Momentum 3: MOMENTUM 3 Wireless | Sennheiser

Sennheiser MOMENTUM 3 Wireless review

The Sennheiser MOMENTUM 3 Wireless is a luxurious noise canceling headset, which is made painfully obvious by the exorbitant original price. Sennheiser relies on its mature design and audio engineering expertise to make the new MOMENTUM Wireless stand out from the sea of capable active noise canceling (ANC) headphones.

We spent two weeks with the MOMENTUM 3 Wireless to learn all that it has to offer. Time to find out if these expensive headphones are worth the money, or if you’re better off with something more pedestrian.

Editor’s note: this Sennheiser MOMENTUM 3 Wireless review was updated on May 17, 2023, to address the MOMENTUM 4 Wireless, add a Controls section, and expand the Alternatives section. We also updated the formatting to match our current style.

Commuters and frequent flyers should consider the MOMENTUM 3 for its ANC, sound quality, and comfortable, premium build. These cans may also appeal to those who valu style as much as sound quality.

What is the Sennheiser MOMENTUM 3 Wireless like?

You can connect multiple devices to the MOMENTUM 3 Wireless.

Sennheiser sourced genuine leather for the headband and plush covering for the memory foam ear cups. Matte steel arms extend from the headband and feature a sliding mechanism for adjusting the fit. The ear cups minimally rotate, allowing them to rest comfortably against your collarbone. Despite the deluxe ear pads, a hotspot always forms at the crown of my head by the 90-minute mark.

These cans hardly deviate from previous iterations: the design is nearly identical save for the button layout on the right ear cup’s edge. It forgoes plastic buttons and sliders, opting instead for a rubberized, matte material.

The Sennheiser MOMENTUM 3 Wireless successful marries style and performance.

Another great feature is multipoint, which lets you connect up to two devices to the MOMENTUM 3 Wireless simultaneously. I use multipoint while working to connect my computer and phone. That way, I can stream music from the former but hear incoming notification dings from the latter.

Rather than the last model’s drawstring bag and stitched case, Sennheiser provides a stout, cylindrical carrying case. The top and bottom panels are stiff but pliable. It’s not as nice as the previous carrying case but has an internal elastic pocket for storing the included 3.5mm cable and USB-C charging cable.

How do you control the Sennheiser MOMENTUM 3 Wireless?

The carrying pouch doesn’t feel as premium as that included with the second-gen MOMENTUM Wireless.

The MOMENTUM 3 Wireless uses button controls that rest on the back of the right ear cup. You’ll find volume buttons flanking a multifunction button for pausing music, skipping songs, and fielding phone calls. Above that, you’ll find a toggle. Sliding this down turns ANC on, and sliding it up turns ANC off. You can use the app to swap out the ANC function for transparency mode. Toward the very bottom is the Bluetooth pairing/smart assistant button.

This third-generation model also does away with the power button. Instead, folding the ear cups toward the headband initiates powering down, something we’ve seen from Jabra and Beats. Beware of the folding hinges that easily pinch fingers

One of my favorite headset features is its auto-pause/play functionality. This occurs when the headphones are removed and worn, respectively.

How do you use the Sennheiser Smart Control app and Tile tracking?

You can track the headphones, customize the EQ, and adjust ANC intensity from the Smart Control app.

Sennheiser’s proprietary app is free on both the Google Play Store and Apple App Store. While it isn’t required to use the Sennheiser MOMENTUM 3 Wireless, it has nifty tools that may be of interest. Like most accompanying headphone apps, this includes a way to customize the EQ and enable voice assistant access. You can also adjust the intensity of transparency mode, which amplifies background noise through the headset. There are three ANC modes: anti-pressure, anti-wind, and maximum, listed in ascending order.

One of the major features separating the Sennheiser MOMENTUM 3 Wireless from the MOMENTUM Wireless 2 is Tile tracking integration. It allows you to see where your headphones are located, which is helpful for the forgetful among us.

How do you connect the Sennheiser MOMENTUM 3 Wireless to your phone?

Memory foam ear pads make the headphones comfortable to wear with or without glasses.

You can connect the Sennheiser MOMENTUM 3 Wireless to your smartphone via NFC or the standard Bluetooth pairing process (Bluetooth 5.0). For the NFC route, enable NFC from your phone’s settings. Then, hold the device next to the MOMENTUM’s right ear cup. A pop-up will appear on your phone confirming a successful pairing process.


Bluetooth codecs

aptX Low Latency,

Once connected, you benefit from three high-quality Bluetooth codecs: AAC, aptX, and aptX Low-Latency. As it stands, AAC’s performance has been historically poor on Android devices, but it’s always been reliable on iPhones. Fortunately for us Android users, we can listen to our favorite tunes over either aptX codec.

For anyone looking for the best possible audio quality, use the included 3.5mm cable. The cable doesn’t have an integrated mic and remote module. However, third-party cables are available for around $12, providing an in-line mic and remote compatible with iOS devices.

How long does the Sennheiser MOMENTUM 3 Wireless battery last?

Metal accents complement the matte black finish.

With noise canceling turned on, the battery lasts 13 hours, 17 minutes. This should get you a whole week of commuting and nearly any international flight. If you listen to levels quieter than 75dB(SPL), which you likely will, the battery should last closer to Sennheiser’s posited 17 hours. When the battery is drained, you can quick-charge the headset with the USB-C cable—just 10 minutes of charging yields 90 minutes of listening.

You can check the remaining battery life via the Smart Control app or by holding the multifunction button down for two seconds. If you need extended battery life from your ANC headset, look into either the Sony WH-1000XM4 or Bose QuietComfort 35 II.

How well does the Sennheiser MOMENTUM Wireless cancel noise?

There’s basically no low-end attenuation, which is a shame given how expensive the headphones are.

Noise cancellation is good, and the technology filters out some midrange frequencies, while the dense ear pads and properly fitted ear cups nearly eradicate high-frequency sounds. However, the low-end attenuation is poor compared to top competitors. There are other benefits to effective noise cancellation, aside from quieting the world around you: good ANC can help prevent noise-induced hearing loss. When external noise is combated, we’re less likely to increase the volume to egregious, eardrum-smashing levels. If you’re looking for a way to justify an expensive purchase of noise cancellers, hearing loss prevention is a good reason.

You have three options for noise canceling:

  • Max: This uses the internal and external mics to reduce noise. It’s the most effective and best for loud environments like a plane or train car.
  • Anti-wind: This uses the internal-facing mics to reduce noise and is best for when you’re moving.
  • Anti-pressure: This uses the external mics to reduce outside noise only, and is best for a fairly quiet environment. It’s a comfortable ANC setting that doesn’t create that “clogged up” ear feeling.

Transparent Hearing amplifies external noise through the headset to keep you aware of your surroundings. You can enable it whether music is playing or not.

What does the Sennheiser MOMENTUM 3 Wireless sound like?

In typical Sennheiser fashion, the headphones sound great. This headset is for general consumers, rather than professionals, and the sound signature reflects that. It’s great for pop and hip-hop as it lends a nice oomph to tunes. However, if you favor folk or classical music, you may find it useful to EQ the sound in the Smart Control app.

Lows, mids, and highs

In Mallrat’s song Charlie, Grace Shaw’s voice is relayed front and center during the first verse. The accompanying piano doesn’t overpower her vocals. Despite the strong low-end, instruments still come through clearly unless it’s during a particularly bass-heavy chorus. It isn’t until the last third of the song (2:29) when the bass kicks in that Shaw’s voice and finger-snapping become hard to hear compared to the low-end; this doesn’t happen when I listen to the same song through my reference Drop x Sennheiser HD 6XX. To completely avoid this, you can lessen the bass response in the app.

Hold up! Something’s different:

This article’s frequency response and isolation charts were measured with our old testing system. We have since purchased a Bruel & Kjaer 5128 test fixture (and the appropriate support equipment) to update our testing and data collection. It will take a while to update our backlog of old test results, but we will update this review (and many others!) once we’re able with improved sound quality measurements, isolation performance plots, and standardized microphone demos. These will be made obvious with our new chart aesthetic (black background instead of white). Each new mic sample begins with the phrase, “This is a SoundGuys standardized microphone demonstration …”

Thank you for bearing with us, and we hope to see you again once we’ve sorted everything out.

How is the microphone on the Sennheiser MOMENTUM 3 Wireless?

The microphone amplifies voices which can cause clipping and the presence of fricatives and plosives. While the mic isn’t bad by any stretch, the person on the other line will know you’re speaking from a headset microphone. If you have a low-pitched voice, others may comment that you sound distant or hollow. This is a consequence of the marked low-end attenuation.

Should you buy the Sennheiser MOMENTUM 3 Wireless?

Tile integration is brilliantly executed, making the Sennheiser MOMENTUM 3 nearly impossible to lose.

The MOMENTUM 3 Wireless is a beautiful pair of noise canceling headphones that put build quality and design first, without ignoring the importance of sound quality. That said, the MOMENTUM 3 Wireless is no longer available through Sennheiser’s website. If you want these headphones, you’ll have to buy them from the likes of Best Buy or Amazon.

Listeners who want the latest Sennheiser headphones should check out the MOMENTUM 4 Wireless ($279.85 at Amazon). These headphones have stellar battery life and sound quality. Sennheiser really stepped up its noise canceling game with the fourth-generation MOMENTUM Wireless, too.

The Sennheiser MOMENTUM 3 Wireless marries style and substance.

The Sennheiser MOMENTUM 3 Wireless builds upon the MOMENTUM line while retaining the same grade-A build quality and style. Connection quality is excellent in part due to the Bluetooth 5.0 firmware and an array of high-quality Bluetooth codecs. If you want a snazzy pair of headphones and aren’t bothered by the high cost, the MOMENTUM Wireless 3 could be your next travel buddy.

What should you get instead of the Sennheiser MOMENTUM 3 Wireless?

Using physical buttons means pressing into the earcup and potentially dislodging it.

The Bose QuietComfort 45 ($329 at Amazon) has much better noise canceling than the Sennheiser MOMENTUM 3 Wireless. While both headsets are comfortable, the QC 45 is a lighter option than Sennheiser’s headset and is a better pick for hours-long listening sessions.

Seeing how the MOMENTUM 3 Wireless can often be found for less than $250 USD, it sits at a much more competitive price bracket than upon its debut. With that kind of budget, you could go for the Sennheiser PXC 550-II ($299.99 at Walmart), which compares rather well against the Bose QC 45. For less than the MOMENTUM headset, you get the same Bluetooth specs and good noise canceling. The PXC is a bit more portable as each headphone can lay flat.

The MOMENTUM 3 Wireless has some stiff competition, specifically from Bose and Sony.

If you don’t mind going the refurbished route, or waiting until a big holiday sale, the Sony WH-1000XM4 ($348 at Sony) is a great option too. The noise canceling is excellent as is the software support. You can listen via wired connection or over the SBC, AAC, and LDAC Bluetooth codecs. Battery life is quite good, but again, the main drawback here is price.

Last but not least, if you want to listen in luxury, might we recommend the Shure AONIC 50 ($249 at Amazon) to you. Shure’s noise canceling over-ear headset has an excellent frequency response that you can equalize in its mobile app, a comfortable build, and replaceable ear pads. If you like the Shure AONIC 40 but don’t want to drop that much money, the AONIC 40 is a little cheaper, lighter, and more flexible. You can find the AONIC 40 for $179 at Amazon.

Frequently asked questions about the Sennheiser MOMENTUM 3 Wireless

It depends what you’re going for: the Bowers & Wilkins PX7 is a handsome headset with significant bass emphasis. The PX7 noise canceling is very good, and outperforms the Momentum 3 Wireless by a long shot. Still, the PX7 is an expensive headset around $400 USD and you can get a similar sound and sophisticated design from Sennheiser’s headset for at least $100 USD less.

No. PlayStation consoles don’t support Bluetooth audio.

No, the Sennheiser MOMENTUM 3 Wireless supports Bluetooth multipoint, which means one pair of headphones can be simultaneously connected to two source devices. The feature you’re describing is what Samsung calls Dual Audio, and Sennheiser headsets do not support it.

Yes, you can connect the Sennheiser MOMENTUM 3 Wireless to your laptop manually. In order to do so, you must hold the voice assistant button for five seconds; this initiates pairing mode. Then, enter the Bluetooth menu on your computer and select the appropriate headset. Once the devices establish a connection, you can listen to media.

For most shoppers, budget is the biggest deciding factor, and the Apple AirPods Max is a very cost-prohibitive headset that retails for $549 USD. If you’re already surrounded by Apple products, it may be a bit easier to justify the price, but most people will be perfectly happy with the Sennheiser MOMENTUM 3 Wireless.

Sennheiser’s headset still costs quite a bit, but it seems modest relative to the AirPods Max. Of course, when you buy the AirPods Max, you’re paying for convenience: each ear cup houses an h2 chip, which facilitates the streamlined user experience—again, exclusive to Apple devices. The AirPods Max uses a hybrid noise canceling system to reduce external noises, much like the Sony WH-1000XM4 and Bose Noise Canceling Headphones 700.

Great question! The Sennheiser PXC 550-II is a great deal and is more affordable than the Sennheiser MOMENTUM Wireless 3 (at least when you compare the two headset’s original prices).

The difference between the Sennheiser PXC 550-II and Sennheiser MOMENTUM Wireless 3 comes down to a form versus function debate. The PXC 550-II has more effective low-frequency noise canceling; in other words, frequent flyers may benefit more from the more affordable headset. However, if you care more about design quality and durability, the premium construction of the MOMENTUM series is hard to beat.

The Sennheiser MOMENTUM Wireless 3 and Shure AONIC 50 are both stylish noise canceling headsets, but the latter mops the floor with the MOMENTUM Wireless 3 when it comes to noise cancellation. Anyone who travels a lot for work or pleasure will be better off getting the Shure AONIC 50 for how well it attenuates low and midrange frequencies. This means low rumbles just melt away when ANC is set to high. For a more accurate representation of sound right out of the box, get the Shure AONIC 50, but for anyone who likes to experiment with custom EQ settings, get the Sennheiser cans or turn your attention toward Sony. The AONIC 50 also supports more codecs than the MOMENTUM Wireless.

The Sennheiser MOMENTUM 3 Wireless has a completely different design than the Bose Headphones 700, even though both are noise canceling headphones. Listeners who want a more accurate representation of their music should get the Bose 700 ANC headphones. Anyone who wants more low-end amplification will gravitate toward the Sennheiser MOMENTUM 3 Wireless for their default bass-heavy sound. Bose’s headphones have more effective passive and active noise canceling than Sennheiser’s headphones.

Sennheiser MOMENTUM True Wireless 3 review

The pressure is on when any company releases a new flagship product, and the Sennheiser MOMENTUM True Wireless 3 has a lot of expectations to live up to, from sound quality to active noise canceling (ANC). With an already strong lineup of wireless earbuds and headphones, Sennheiser adds a bunch of extras to bolster the MOMENTUM True Wireless 3. We tested the MOMENTUM True Wireless 3 for about a week, so here’s the rundown.

Editor’s note: this Sennheiser MOMENTUM True Wireless 3 review was updated on May 1, 2023, to add the Sony LinkBuds S and Google Pixel Buds Pro as alternatives, and to answer a FAQ about mono listening.

About this Sennheiser MOMENTUM True Wireless 3 review: We tested the Sennheiser MOMENTUM True Wireless 3 over a period of one week. It was running firmware version 2.3.9. The company provided the unit for this review.

People with money to burn will enjoy the good sound and customization in the Sennheiser Smart Control app. Consumers who want all of the conveniences of wireless earbuds will like the MOMENTUM True Wireless 3.

What’s it like to use the Sennheiser MOMENTUM True Wireless 3?

The Sennheiser MOMENTUM True Wireless 3 (or MTW3) represents an iterative update to the MOMENTUM True Wireless 2. It comes in a tweed-covered case with a USB-C charging connection (and USB-C cable), and four sets of silicone ear tips, which range from 10-15mm in diameter. Like the popular Amazon Echo Buds (2nd Gen), the MTW3 ships with three sets of silicone wings that wrap around the outer edges of the buds to lock in the fit. I use the 11mm (size small) set of ear tips and the largest stabilizers. Pleasingly, the ear tips are the most hassle-free to swap out I’ve ever experienced: they just fit over the 7mm earbud nozzles. You don’t have to exert any force trying to get them on. The same goes for the stabilizers.

Our test set is the Graphite colorway, but there are White and Black options too.

The MOMENTUM True Wireless 3 is a bit chunky and the case is a bit heavier than it looks, but I suppose that’s to accommodate the thick earbuds. Everything feels solid, from the satisfying magnetic click of the buds fitting into the case, to the snap that emanates when the clamshell lid shuts. The MTW3 has a IPX4 certification, meaning you have some waterproofing. While the buds stay in my ears reasonably well, I wouldn’t go for a jog with them—they don’t quite fit well enough for that.

Fortunately, the touchpad is obviously on the flat exterior of the housing, and this makes adjustments easy and mostly free of misfires. After two hours my ears experience some discomfort from fatigue. For daily use, like going for walks, commuting, or performing office work the MOMENTUM True Wireless 3 has a good enough in-ear fit.

It’s a decent number of ear tips, and the stabilizers make a difference in the fit.

Unlike the pair-and-go earbuds out there the MOMENTUM True Wireless 3 requires some of your time to set up. Sennheiser advises performing a quick 30-second charge when you open the box to pair. Yours may require a firmware update too. This is very much designed for people who like to tinker with apps and adjust fit.

You get some new features like Sound Zones (covered more in the Software section). This allows you to set up listening preferences depending on your geographic location. You can make your office a zone where the buds automatically turn on ANC and podcast EQ, for instance. I find this handy when I’m working from home, and I have ANC on, but when I leave the buds in to walk the dog, it switches to Transparency Mode automatically. You also get conveniences like wireless charging, and a quality build.

How do you control the Sennheiser MOMENTUM True Wireless 3?

These are the default settings that you can control on the MTW3. Press and hold for volume is very handy.

In an everyday capacity, the Sennheiser MOMENTUM True Wireless 3 has the right amount of touch sensitivity (Samsung, please take note.) The only time I experience misfires is when I remove the buds and have them in my hands—usually, it amounts to making paused audio start playing again. You can turn off the touch controls completely in the Smart Control app, but you lose out on some of the key features if you do that.

Should you download the Smart Control app?

As mentioned already the MOMENTUM True Wireless 3 requires some set up time. Sennheiser includes a QR code, or you can go to the Google Play Store or Apple Store to download the Smart Control app. Our test set immediately required a 21-minute firmware update (we’re reviewing version 2.3.9). So, yes, you should download the Smart Control app at the very least for updates.

Part of the appeal of the MOMENTUM True Wireless 3 is the extensive app. Ignore the “Discover” tab, because it’s mostly just Sennheiser adverts for its own products.

In the app, you’ll see tiles pertaining to different options: your connected devices list, three-band equalizer, Sound Check (which lets you test custom EQ presets), Transparency Mode settings, Adaptive Noise Cancellation, “Sound Zones,” and Touch Controls. You can also tap the Settings tab to reorganize the tiles as you like—a very nice touch.

The included equalizer is not as detailed as we might like. It features three modifiable sliders that affect bass, mids, and treble up to 6dB in volume (up or down). Sennheiser does not specify which frequencies these bands alter, which makes it more difficult to dial in your EQ. That said, it lets you save your custom presets, which is handy. It also has Bass Boost and Podcast presets you can toggle on and off.

On the left is the main menu, and on the right is the truly basic equalizer. What, for instance, does Sennheiser classify as treble?

Sound Check lets you create and play with custom presets that you can add to your personal library. If the included equalizer gave more information about the frequencies affected, this would be a really great idea to truly harness the best possible sound for every listening scenario. My fingers are crossed for an update.

Adaptive Noise Cancelling

Sennheiser equips the MTW3 with a form of active noise canceling (ANC) that turns on and off, as well as an Anti Wind mode. Anecdotally, the Anti Wind mode works quite well compared to just having the Adaptive Noise Canceling turned on during those windy days.

This feature is still pretty self-explanatory, but it does more than just turn off and on. Unlike a basic transparency mode, the MOMENTUM True Wireless 3 lets you turn it off, on with music, and on when you pause music. It also supplies a slider to finesse how much environmental sound to let it. The discerning listener will like this feature.

What are Sound Zones?

Sign away your location and you gain the advantage of seamless audio settings based on your preferences for different locations.

“Sound Zones” is one of the more interesting features in the app. Equipped with a map you can customize locations you frequent, like your home, or workplace and save preferred ANC and EQ settings. Once you enter the radius—as set by you on the location map—your settings will automatically change to the saved setting for that Sound Zone. You also set what happens when you leave a zone. Either the settings stay as is until you enter another Sound Zone with different ANC and EQ, or they automatically switch to your saved preferences when you leave a determined zone.

You get notifications when you enter a new Sound Zone so you shouldn’t be surprised when the settings change either. To access these settings you have to create an account (or sign in, if you have an account with Sennheiser already), and consent to more data collection, specifically location-related data. It’s a novel use of location tracking and works well.

How does the Sennheiser MOMENTUM True Wireless 3 connect?

Finding the touch control area is super easy; it’s on the Sennheiser logo.

Sennheiser kits out the MOMENTUM True Wireless 3 with a suite of codecs: aptX Adaptive, aptX, AAC, and SBC. In the Smart Control app under “Settings,” you’ll see which codec your device uses. Our tests were all done with aptX, which yields the highest potential quality audio the MTW3 can offer. aptX Adaptive is a nice option for folks using Android devices that watch many videos or deal with patchy internet connections. This is because while aptX has the higher potential data transfer and generally low latency that’s good for video, aptX Adaptive adjusts the audio quality to prioritize low latency and maintain a strong Bluetooth connection. Without altering any settings, the earbuds default to aptX with my Samsung phone.

If you’re part of the Apple ecosystem, the aptX inclusion is a moot point, as you’ll only be using the AAC codec. However, if like a lot of people you have a Windows machine and an iPhone, you may still benefit from aptX if your PC is capable.

The connection is mostly stable over aptX to a distance of about eight meters, after which the buds began to experience connection issues. A couple connection drops can occur no more than one meter away too, which is surprising. It should not pose a problem for most users, but it’s also not as stable as it should be.

On November 2, 2022, Sennheiser released an update allowing 24-bit/96kHz streaming to the MOMENTUM True Wireless 3. This “Hi-Res” mode in the app only works with aptX Adaptive and increases the bitrate to 420kbps. To get this feature, you must update the buds’ firmware to 2.10.19 or later and the app must run version 4.1.5 or later.

The MTW3 should automatically enter pairing mode when you remove both buds, indicated by a flashing red and blue LED. If this doesn’t happen automatically, place both buds in your ears and hold down on each touchpad for 3 seconds to trigger pairing mode. In use, it links back to your device very quickly after being disconnected.

How long does the battery last on the Sennheiser MOMENTUM True Wireless 3?

The charging pad doesn’t come with the package, but if you have one already it’s handy.

According to our standardized battery testing the Sennheiser MOMENTUM True Wireless 3 lasts 5 hours, 33 minutes on a single charge. This result is reasonably good, and the charging case has an additional three charges totaling 22 hours of battery. You can also use a wireless Qi charging pad to keep the case topped up, or the included USB-C cable.

A 10-minute quick charge provides 60 minutes of playtime to the buds.

Is the Sennheiser MOMENTUM True Wireless 3 noise canceling any good?

This is definitely flagship ANC performance.

Secure yourself a good in-ear fit and the MOMENTUM True Wireless 3 is very capable of canceling noise. Passive isolation is impressive, managing to reach over 45dB of attenuation around 10kHz. Although, that looks good on a chart, more impressive is how comprehensive the isolation is, particularly around 1kHz (where a lot of environmental sounds are), down into the lows. Low sounds are usually the area of struggle for passive isolation, with some earbuds blocking zero lows, but not here.

Active noise canceling (ANC), which Sennheiser labels as “Adaptive Noise Cancelling” in the Smart Control app, is very good too. Besides a narrow band at 400Hz where both isolation and ANC dip down to just above 10dB of attenuation, from 1000Hz and below the ANC mainly hovers between 20dB and 30dB of cancellation. This is more than sufficient for your commute or your office to focus, or alternately, zone out. Anecdotally, it successfully mutes my very vocal cat.

How does the Sennheiser MOMENTUM True Wireless 3 sound?

The MOMENTUM True Wireless 3 (cyan) follows our target curve (pink) closely, except for the highs.

On the whole, the MOMENTUM True Wireless 3 has a very pleasant frequency response, though treble takes a backseat to bass and midrange sound. Compared to our headphone preference curve, the MTW3 only really deviates significantly in the highs.

From 2.5-10kHz in the treble region, there is under-emphasis relative to our preference of anywhere from a couple of decibels down to almost 10dB. Generally, this leads to hearing everything in the lows and mids very well. You may be tempted to turn up your volume, because treble might be just that bit too quiet, but please don’t do that. On the flip side, it also means you won’t experience ear fatigue from too much treble. Here’s where one can suggest using the included equalizer to turn up those frequencies, but the Smart Control app doesn’t tell you which frequencies you can adjust. Even so, you can play with it to your liking, or go with a third party equalizer.

Lows, mids, and highs

The new stabilizers help give the MOMENTUM True Wireless 3 a more universal fit than its predecessor.

Sennheiser’s sound works with a variety of music genres. The frequency response highlights the disco-inspired bassline in the song Negroni Summer by Donny Benét, and Benét’s airy voice is audible, if just a touch too quiet. During the bridge beginning at 2:25, the saxophone solo plays in excellent comparative volume with the kick and bass. Throughout most of the track, the relative volume of keys sounds just a bit too quiet but not egregiously so.

It’s not altogether unpleasant and for some tracks, it works better than on others. Girl and the Sea by The Presets sounds just about perfect. Low vocals sit at the right volume, while bubbly sequenced synths in the intro and verse are easy to hear too. The high-pitched synths and heavily processed rhythm guitar at the chorus are tamed to the right volume, while the driving bass and kick provide a satisfying groove.

Using the limited equalizer in the app, you can crank the treble slider up by 6dB (though I tend to leave it more around +2dB most of the time). Doing that with the Donny Benét song reveals more detail in the vocals and the muted guitar in the verse than before. The drum machine’s hi-hats come through much more obviously too.

However, I don’t think this EQ fully resolves the frequency response under-emphasis in the highs. The equalizer is too limited to make informed adjustments. Sure, a lot of people don’t know which frequencies apply to which sounds, but Sennheiser could easily label a slider “treble” and the frequency affected.

Can you use the Sennheiser MOMENTUM True Wireless 3 for phone calls?

Voices experience some inaccurate reproduction with these buds.

You can use the MOMENTUM True Wireless 3 for calls, although it’s mostly just okay. Voices are captured with some under-emphasis in both the highs and lows. When taking a call in less than ideal conditions, say in a noisy office or on the street, the MTW3 filters out the lows heavily. Your voice will still be audible, but any noises in the highs will still come through too in a kind of noise haze—think keystrokes and car sounds.

Take a listen and let us know what you think.

Should you buy the Sennheiser MOMENTUM True Wireless 3?

Sennheiser is really aiming for the top tier with the MOMENTUM True Wireless 3, in price and specs. For people who just want basics like good sound and serviceable ANC, this might be kind of expensive. With that said, the noise canceling is rather good, with upgraded features like anti-wind for noise canceling, and the sound is solid too.

The strong case magnet hampers single-handed operation, but it also stays closed in your bag.

While the connection of our test unit isn’t always totally steady, it’s possible another update could resolve that. All the touch controls work effortlessly, as does in-ear detection. People who don’t want to sign over data like location tracking will miss out on the novel Sound Zones feature, which might mean it’s not the right choice for you. Sennheiser could take some cues from Shure or JBL and implement a more comprehensive equalizer at this tier.

By and large, the sturdy build of the case and buds, the IPX4 rating, and the two-year warranty greatly allay any durability worries. Skipping allegiances to any OS doesn’t go without saying these days as the brand specific earbuds wars continue, let’s express gratitude for Sennheiser making a product that works with Apple and Android. If you don’t want to compromise while looking for true wireless earbuds, you won’t have to make many with the MOMENTUM True Wireless 3.

What’s the difference between the Sennheiser MOMENTUM True Wireless 2 and MOMENTUM True Wireless 3?

The Sennheiser Momentum True Wireless 2 similarly has a fabric case and chunky buds, but without additional stabilizers.

In looks, both the newer MOMENTUM True Wireless 3 and Sennheiser MOMENTUM True Wireless 2 have quite a lot in common, starting with a tweedy charging case. They weigh almost the same, with the MTW3 gaining an extra overall 7g. Both possess IPX4 ratings against water and sweat. Even in touch control functionality, not much is different. The ANC is controlled by default on the right earbud with the MOMENTUM True Wireless 2, as opposed to on the left with the newer version, but both use the same Smart Control app.

The real differences come down to details: while the MOMENTUM True Wireless 3 has AAC, SBC, aptX, and aptX Adaptive codecs, the predecessor has the same except it’s missing aptX Adaptive, and the November 2022 update to the MTW3 now makes it capable of “Hi-Res” audio. Battery life on the MTW3 is longer than the MOMENTUM True Wireless 2 which runs 4 hours on a single charge.

You won’t hear much of a difference between the passive isolation and active noise canceling with these buds.

ANC and sound are where you’ll find some of the major updates with the MTW3. The MOMENTUM True Wireless 2 barely attenuates in the lows, often not even achieving 10dB in reduction. By contrast, the MTW3 all but mutes an impressive 30dB at 100Hz. It utterly blows the MOMENTUM True Wireless 2 away with noise canceling.

The frequency response on both sets of earbuds is pretty good. The MOMENTUM True Wireless 2 has a “flatter” frequency response with under-emphasis in sub-bass and between 2-7kHz. You can tweak this in the app, although only with the three-band EQ. Bass and mids in the MOMENTUM True Wireless 3 more closely follow our house curve, meaning you get a little more oomph. In addition, the MTW3 also has some under-emphasis in the highs above 2kHz as well.

With only a bit of under-emphasis on the highs, the Sennheiser MOMENTUM True Wireless 2 is an exceptionally decent set of earphones.

The MOMENTUM True Wireless 2 has gone down in price ($149.95 at Amazon) now that the newer model is out, and still offers good sound and functionality. If you already own the MOMENTUM True Wireless 2, unless you need improved ANC, it may not be worth the upgrade. However, if you own neither, the newer one is worth it for the noise canceling and better battery life.

Should you get the Sony WF-1000XM4 or Sennheiser MOMENTUM True Wireless 3?

Pairing the earphones is easy after the first time.

Both the Sony WF-1000XM4 and Sennheiser MOMENTUM True Wireless 3 are top-tier earbuds. Both will make most listeners very happy but take slightly different approaches. You get some high-quality codecs with either pair of earphones. The MTW3 uses aptX and aptX Adaptive (and AAC and SBC), as opposed to the WF-1000XM4, which has LDAC (as well as AAC and SBC). We’ll give Sennheiser the edge here, but most listeners won’t notice much difference.

Sony pushes ahead with a greater battery life per charge. The WF-1000XM4 lasts 7 hours, 43 minutes, compared to 5 hours, 33 minutes with the MOMENTUM True Wireless 3. Sony also has a more detailed equalizer in the app. However, the UI/UX on the app is notably clunkier than the Sennheiser app, which could otherwise benefit from a more granular equalizer function.

You can see the Sony WF-1000XM4 better isolates in the highs, while the Sennheiser MOMENTUM True Wireless 3 cancels more low-end.

It’s safe to say that both earbuds do a great job of muting your environment. The WF-1000XM4 relies heavily on a good in-ear fit to deliver better isolation than the MTW3, but Sennheiser manages to outdo the Sony below 400Hz in ANC performance. Particularly, the MOMENTUM True Wireless 3 really quiets sub-bass noise and noises around 900Hz compared to the WF-1000XM4. Even so, isolation on the Sony WF-1000XM4 will go a long way in dampening high-pitched sounds.

From the mids down, the earbuds are barely distinguishable sounding from each other.

Neither set of earbuds sounds perfect, but they each sound good and follow our target curve reasonably well, especially in the mids and bass. Both Sony and Sennheiser under-emphasize treble, although the MOMENTUM True Wireless 3 holistically reaches closer to our ideal in the highs. Fortunately, you can amend these deviations in the frequency response to some extent with the in-app EQ Sony and Sennheiser provide.

Sony might have the upper hand for folks who want surround sound, with its 360 Reality Audio, although its implementation is still quite limited. In this price range, both sets are winners. You can find the Sony WF-1000XM4 for $178 at Amazon.

What should you get instead of the Sennheiser MOMENTUM True Wireless 3?

Check out the family resemblance with the Sennheiser CX Plus True Wireless.

Check out the Sennheiser CX Plus True Wireless if you want very good ANC and sound without extras like Sound Zones. It has a similar shape as the MTW3 and a similar frequency response at a cheaper price. It also uses the aptX codec and AAC, so you need not compromise. It’s a wise choice, if not the most decked-out set, and costs $69.95 at Amazon.

Sportier listeners may instead opt for the Sennheiser Sport True Wireless which includes wing sleeves and a slightly different design. You don’t get ANC on the Sport True Wireless which is a “pro” for some and a “con” for others. The Sport True Wireless will run you $99.95 at Amazon.

Understated is the name of the game with the LinkBuds S.

In addition to the Sony WF-1000XM4 earbuds, the Sony LinkBuds S is a bit of a sleeper hit. With an understated style, the matte textured buds stick to stay in-ears without using a stabilizer. Plus, if spatial audio is important to you, the Sony buds are capable of delivering. Like Sennheiser, Sony doesn’t pressure users to pick an OS, so the AAC and LDAC compatible LinkBuds S work regardless of whether you’re an Apple or Android fan. In action, both earbuds have similar battery capacities, and pretty close to the same noise canceling capabilities as well. The buds even sound rather alike, with the MTW3 having more volume above 7kHz. It’s a tight race, but if Sony is more your style pick up the LinkBuds S for $148 at Amazon.

Alternatives for exclusively Android or Apple

When choosing between the Galaxy Buds 2 Pro and AirPods Pro (2nd gen), you may need to know that the Samsung earbuds are IPX7-rated, while Apple’s earbuds (and case) have an IPX4 rating.

Android users, particularly Samsung phone owners, may want to save a few bucks with the Samsung Galaxy Buds 2 Pro, which lacks stabilizers and Sound Zones, but feels good to wear. Its frequency response boosts more bass and treble than Sennheiser’s buds. Paired with a Samsung device, you can use the Samsung Seamless Codec and the Android-exclusive Galaxy Wearable app. Its ANC is among the best out there currently, but the battery life is a touch shorter. You only get EQ presets on the Galaxy Buds 2 Pro. The Samsung Galaxy Buds 2 Pro go for ($189.99 at Amazon).

For productivity minded folks the Google Pixel Buds Pro has a few tricks up its sleeve, such as automatic translation. Rather than concentrating on codecs, Google gave the Pixel Buds Pro simply AAC and SBC, so you won’t get that “Hi-Res” audio present on the Sennheiser MOMENTUM True Wireless 3. Instead, the buds are smaller, lighter, and more comfortable (albeit, less secure). When paired with a Google Pixel device you can use spatial audio with head tracking. With very good ANC in addition to a greater battery life, the Pixel Buds Pro might fit your life better if you have a Pixel device; it sells for $192.5 at Amazon.

Consider matching your iPhone with the new Apple AirPods Pro (2nd generation), which has a pretty similar frequency response as the Sennheiser buds. The AirPods Pro (2nd generation) has a slightly longer battery life than the MTW3, and noise canceling is not so different either. Because it uses AAC and SBC codecs with Apple OS-specific features, only buy the AirPods Pro (2nd generation) to pair with an iOS device. The stemmed design is polarizing and may catch on face masks, but the sliding gesture for volume is neat. You’ll pay $229 at Amazon for these Apple earbuds.

Frequently asked questions about the Sennheiser MOMENTUM True Wireless 3

As of November 2, 2022, the MOMENTUM True Wireless 3 does support multipoint connectivity. To access this, the earbuds must run firmware 2.10.19 or higher, and the Smart Control App must be version 4. 1.5 or higher. Multipoint switching is works over any mutually supported Bluetooth codec.

Yes, the Sennheiser MOMENTUM True Wireless 3 works in mono mode with either left or right earbud.

We recommend Samsung and Apple’s earbuds over the Bose QuietComfort Earbuds II for now because the QC Earbuds II cannot disable ANC and has a wonky default frequency response. Bose and Apple’s noise canceling earphones share a stem-like design, but Bose’s is more expensive at $279 at Amazon. Unlike the Galaxy Buds 2 Pro and AirPods Pro (2nd gen), the Bose QC Earbuds II case lacks wireless charging. If you’re willing to throw down $200 USD or more on wireless earbuds, there are better options.
