Skullcandy Hesh ANC review – SoundGuys
Skullcandy wants you to know that you don’t have to “flex” with expensive cans to enjoy active noise cancelation (ANC). Though it appears fairly plain, the Skullcandy Hesh ANC sets out to rival pricier noise canceling headphones. We spent a week with the Hesh ANC to find out if the headset succeeds.
Editor’s note: This review was updated on June 23, 2023, to add the Skullcandy Crusher ANC 2 to Alternatives.
Anyone who wants over-ear headphones with noise canceling, but doesn’t want to pay a fortune can pick up these over-ear cans. They compact easily for travel and are more flexible than many flagship ANC headphones. If all of this sounds appealing to you and you’re a bass head, then this headset is tailor-made for you.
What’s it like to use the Skullcandy Hesh ANC?
The Skullcandy Hesh ANC is an over-ear noise canceling headset made of plastic, with a memory foam cushion on the band and thick memory foam ear pads wrapped in faux leather. The ear pads fit snugly but are comfortable around my ears. Anyone with bigger ears may have difficulty with a proper fit. Interior ear pad dimensions measure just 40mm by 60mm. For comparison, Sony WH-1000XM4 ear pads are about 50mm by 70mm.
The ear cups swivel 180 degrees and fold up toward the band, so you can easily transport the headset.
On the right ear cup, you’ll find everything of interest. There’s a row of buttons to control media playback or answer calls, and below that, you’ll find a recessed port that houses the USB-C input and headphone jack. Unlike the Bose Noise Cancelling Headphones 700, you don’t get button and touch controls. Instead, the Hesh ANC is a tactile-only experience.
Skullcandy includes a 3.5mm jack cable for wired listening, as well as the shortest USB-A to USB-C cable I’ve seen. It also comes with a thin fabric carrying pouch. The pouch won’t protect from a tumble down the stairs, but it prevents the plastic ear cups from scratching up too much.
Track your Skullcandy headphones with Tile
The Hesh ANC comes with a carrying pouch, 3.5mm cable, and the tiniest charging cable.
Tile tracking integration appears on the Hesh ANC, which we’ve seen with more modern headsets like the Skullcandy Grind Fuel. You can pair the Hesh ANC to the Tile app, so you are always able to track it down, whether you left it on top of the fridge or on the bus. Tile needs to use location data to do this, so if you’re extra careful about privacy, pass on this feature.
First, you’ll need to download the Tile app, available on the App Store and Google Play. Then, open the app and hold down the multi-function button and the plus button for one second to pair the Hesh ANC with Tile.
How do you control the Skullcandy Hesh ANC?
The right ear cup has buttons for controlling the Hesh ANC.
The Skullcandy Hesh ANC has controls on the right ear cup, with a hollow circular button as the ANC button, a plus and minus button for volume up and down, and a multi-function button between the two. All buttons have a rubberized coating to help differentiate them from the headphone’s plastic. Our table below illustrates all of the buttons’ various functions:
Play/Pause/, Answer/End call
How does the Skullcandy Hesh ANC connect?
The Skullcandy Hesh ANC has support for the SBC and AAC Bluetooth codecs.
The Skullcandy Hesh ANC connects wirelessly over Bluetooth 5.0, using the SBC or AAC Bluetooth codecs. When you want to tap into your lossless media library, you can use the 3.5mm wired connection. The Hesh ANC lacks a reliable high-quality Bluetooth codec for Android phones like aptX, but that’s expected at this price.
Connecting the Skullcandy Hesh ANC to your devices is as simple as any other Bluetooth headset:
- Start with the headset off.
- Hold down the ANC button to turn the headset on and enter pairing mode.
- Go into your device’s Bluetooth settings.
- Choose “Hesh ANC,” and you’re connected!
How long does the Skullcandy Hesh ANC’s battery last?
Skullcandy advertises a 22-hour battery life with the Hesh ANC, which is close to our test results. In our battery testing of consistent music output peaking at 75dB(SPL), the Skullcandy Hesh ANC lasts 22 hours, 58 minutes. This is longer than the Sony WH-1000XM4 battery life of about 20 hours, and the Bose Noise Cancelling Headphones 700 battery life is 21 hours. Like other headsets, the Hesh ANC has quick charging. You can get three hours of listening time from just 10 minutes of charging with the USB-C cable.
Yes, battery life will be longer with ANC turned off. Skullcandy claims the battery life is 30 hours or more without ANC.
How well does the Skullcandy Hesh ANC cancel out noise?
The noise canceling cuts low and midrange frequencies, and passive isolation is average.
The Skullcandy Hesh ANC does a pretty great job canceling out noise for such a cheap set of headphones. I frequently run a loud portable air conditioner, and the ANC completely blocks and filters out the low droning noises.
The isolation is just okay, and I can still hear a lot of incidental noises like typing, snapping fingers, and clanking dishes. You’ll want to get the best fit around your ears you can to block out the most noise, and ensure optimal ANC performance. I can hear voices clearly when someone is right next to me with ANC on, though it’s a bit muffled.
How does the Skullcandy Hesh ANC sound?
This sub-bass response is much louder than we recommend.
The frequency response chart for the Skullcandy Hesh ANC shows a major boost in the sub-bass, and a big boost in the treble frequencies compared to our consumer target curve. This means low bass frequencies will be louder compared to the music producer’s intent, and this could result in bass loud enough to negatively impact the mid range frequencies. If you want to hear your music without excessive amounts of sub-bass enhancement, you likely won’t enjoy this frequency response.
Lows, mids, highs
Music sounds good through the Skullcandy Hesh ANC. With bass being boosted, genres like EDM or hip hop will sound a lot more bassy, and if that’s your cup of tea, you’ll really enjoy the sound of the Hesh ANC.
Last Nite by The Strokes has a pretty prominent bass line and loud kick drum, but there are no issues with bass frequencies masking mids or highs. The kick drum is enjoyably prominent, Julian Casablancas’ voice comes through among the bass line throughout, and the guitar part is still very audible.
The sub-bass in Lose Yourself To Dance by Daft Punk featuring Pharrell Williams is very loud through the Hesh ANC, enough that it’s a bit jarring. The song still sounds good overall, but the sub-bass is a bit distracting to me. If you really like to “feel” your music with heavy sub-bass, you’ll enjoy how Daft Punk and other EDM sounds with the Hesh ANC.
Can you use the Skullcandy Hesh ANC for phone calls?
The microphone does a reasonable job with the essential speech frequencies, and won’t sound at all “hi-fi”.
The microphone on the Skullcandy Hesh ANC isn’t the best, but it’s certainly fine for phone calls. When taking calls on it, make sure there’s not too much background noise, because the noise suppression isn’t that great on this headset. It does an okay job of suppressing background noise, but unpredictable sounds still make it through.

Should you buy the Skullcandy Hesh ANC?
These are affordable noise canceling headphones.
The Skullcandy Hesh ANC are fine noise canceling headphones for their price. You get effective active noise canceling, decent battery life, fairly muted aesthetics, and a comfortable build. Although microphone quality could be better, that’s par for the course in this price bracket. The sound profile will mainly appeal to bass heads and those willing to mess with a third-party EQ app, but it’s a small price to pay for an otherwise complete package.
There are a lot of decent ANC headsets out there, but this is worth considering if you don’t want to spend serious money.

What should you get instead of the Skullcandy Hesh ANC?
Monoprice’s headset supports aptX HD and AAC.
One of the best affordable noise canceling headphones out there is the Monoprice BT-600ANC. It has great ANC and isolation, an amazing 36-hour battery life, and support for aptX HD. The sound quality is bass-heavy here too, but if you’re looking for super cheap and ANC, this is a great option ($89 at Amazon).
Another really nice noise canceling headset at a similar price point to the Hesh ANC is the Anker Soundcore Life Q35. It has LDAC support, a 52-hour battery life, and a bassy frequency response. The noise canceling isn’t quite as good as the Monoprice BT-600ANC, but it’s solid for the price ($99 at Amazon).

The Skullcandy Crusher ANC 2 folds up to make it portable.
Skullcandy upgraded its Crusher series with the newest Skullcandy Crusher ANC 2 ($229.99 at Manufacturer site). If bass is where you’re at, these deliver via a dial that directly controls the Crusher (low end volume) mode. Besides the hefty low end, the headphones feature noise canceling and a competent app too. Per-function buttons are fully editable and reassignable as well for the tinkers out there. Still, these are definitely bassy.
What is the best pair of noise canceling headphones?
The Sony WH-1000XM5 (left) diverges from the WH-1000XM4 (right) with its new headband adjustment system and cleaner design.
If you have more money to spend on noise canceling headphones, consider the Sony WH-1000XM4 ($348 at Amazon), or even the newer WH-1000XM5 if you’re feeling particularly flush ($387 at Amazon). Both headsets have top-of-the-line noise canceling and excellent sound quality, and great mics too. You can read how the two headphones compare in our detailed versus article.

Skullcandy Hesh ANC Review | PCMag
While we’ve been seeing an influx of noise-cancelling true wireless headphones below $150, the same can’t be said for over-ear noise-cancelling headphones, which tend to cost $200 or more. Thus, Skullcandy’s Hesh ANC headphones are automatically notable for their $129.99 price. Sonically, they deliver a bass-forward, highly sculpted sound signature. The ANC (active noise cancellation) performance is about what we expect for this price—nothing groundbreaking, but effective against deep low frequencies. Ultimately, the price is the most appealing feature here, though you can also find stronger options like the Sennheiser HD 450BT discounted to a similar amount.
The Hesh ANC headphones are available in black, gray, or white, with circumaural earcups generously padded with memory foam and a leather-like lining. The underside of the headband is also well-padded, and the headphones feel comfortable even over long listening sessions.
The controls along the right earcup’s side panel work well and are easy to feel, with a central playback button that doubles as the call management and power button. There are plus/minus buttons that control both volume and track navigation—we’re not huge fans of this design choice, as it makes it easy to accidentally skip a track when you mean to adjust the volume. There’s a dedicated ANC on/off button, and pressing it twice puts the headphones in ambient mode.
Internally, 40mm drivers deliver a frequency response of 20Hz to 20kHz, with 32-ohm impedance. The headphones are compatible with Bluetooth 5.0 and support the SBC Bluetooth codec, but not AAC or AptX.

Skullcandy estimates the Hesh ANC’s battery life to be roughly 22 hours, but your results will vary with your volume levels and your use of ANC.
A very short USB-C-to-USB-A charging cable is included, as is a drawstring travel pouch. The headphones have Tile built in, so you can use the Tile app to locate them if they’re lost nearby. What’s missing? An app with customizable EQ would welcome, though not necessarily expected at this price.
Hesh ANC Noise Cancellation and Audio Performance
The Hesh ANC headphones deliver decent noise cancellation for the price. They do a solid job of dialing back deep low-frequency rumble, like you’d hear on a plane. That said, a recording of a loud, busy restaurant played through near-field monitors gave the headphones some trouble. At lower volumes, they were able to tamp down the noise for the most part, but at high volumes, the highs seem to not only escape the ANC circuitry, but perhaps even get louder—there’s a weird effect in the earcups when this happens, as though you’re hearing the highs through the ambient mics.
The ANC emits a high-frequency hiss (not unpleasant—think faint white noise), which is common among affordable noise-cancelling headphones. It’s most evident in a quiet room, where you can hear things actually get slightly louder when ANC is enabled. You can hear just a bit of the hiss mixed in, but again, this is common and not a deal breaker for this price.
See How We Test Noise-Cancelling Headphones
In addition, the ANC also seems to have a noticeable effect on the audio performance. When it’s off, there’s a little more sub-bass depth, and when it’s on, things sound a bit brighter. Even though the change doesn’t sound bad, it’s another sign of inexpensive ANC circuitry. On the plus side, ambient mode is well-implemented, and you can easily hear your surroundings with a natural volume level without taking the headphones off.
When it comes to audio, on tracks with intense sub-bass content, like The Knife’s “Silent Shout,” the headphones deliver powerful low-frequency response, and at top volumes, avoid distorting. The bass depth still sounds strong at moderate listening levels.
Bill Callahan’s “Drover,” a track with far less deep bass in the mix, gives us a better sense of the Hesh ANC’s general sound signature. The drums on this track get some added thunder—this is definitely a bass-forward sound signature. Callahan’s vocals are also given some added low-mid richness that they arguably don’t need. The highs are dialed up, too—the tape hiss is a little louder in the mix than it normally is, and the acoustic strums sound bright. It’s those drums that stand out, though—they’re heavy and borderline unnatural. Thankfully, the higher-frequency sculpting keeps things from veering into muddy territory.
On Jay-Z and Kanye West’s “No Church in the Wild,” the kick drum loop receives plenty of high-mid presence, allowing the attack to retain its punchiness. The vinyl crackle and hiss take a step forward in the mix, as well—this is a bright sound signature, even with all the added bass depth. The sub-bass synth hits are delivered with true power here—they don’t quite overwhelm the mix, but the drivers are able to pump out lows that other headphones don’t quite reach down for. The vocals on this track sound a little more sibilant and slippery than usual with those dialed-up high-mids and highs added into the mix. The mids sound like they aren’t nearly as present as they could be, which makes for a scooped sound signature with deep lows and dialed-up highs.
Orchestral tracks, like the opening scene from John Adams’ The Gospel According to the Other Mary, get more bass depth than they need. It doesn’t sound terrible, but the lower-register instrumentation steps forward from its subtle anchoring role and occasionally sounds booming. The higher-register brass, strings, and vocals retain their bright presence and the focus of the mix, but this isn’t a sound signature for those seeking a transparent listen.
The mic offers solid intelligibility. Using the Voice Memos app on an iPhone 8, we could understand every word we recorded—there wasn’t much Bluetooth distortion fuzzing up the signal, and the mic even provided a hint of low-frequency response. Callers should understand you easily on a solid cell connection.
Affordable, Average ANC
Skullcandy’s Hesh ANC headphones deliver decent noise cancellation for the price, but nothing outstanding. Audio quality is also solid, if seriously sculpted. As mentioned earlier, our favorite affordable noise-cancelling headphones in this price range are Sennheiser’s HD 450BT, which debuted for $200 but can now be found for much less. If you’re willing to go the true wireless route, we also like the $130 Anker Soundcore Liberty Air 2 Pro. Beyond that, you really need to spend more to get high-quality ANC, with the best pairs like the Sony WH-1000XM4 and the Bose Noise Cancelling Headphones 700 falling in the $300 to $400 range. All of this said, if you want wireless audio with boosted bass depth and bright highs, the Hesh ANC headphones also provide decent noise cancellation for the price.

Fully Wireless Headset Review
It’s no secret that for many users a wireless headset is not only a way to listen to music and communicate, but also an element of style. And if we are already familiar with very good sounding solutions, then a truly original and catchy design is rare. The heroine of today’s test can stand out quite strongly from the crowd, at least thanks to the bright color, not to mention the recognizable logo. At the same time, it also sounds acceptable, has good autonomy and a comfortable fit . .. True, it is also not without flaws – we will definitely talk about them separately. Well, let’s start traditionally with the declared technical characteristics and design.
|Declared frequency range
|20 Hz – 20 kHz
|<3% (1 kHz / 94 dB)
|up to 5 hours
|Autonomy with charging case
|up to 24 hours
|USB Type C
|Weight per earpiece
Packing and contents
The headset is delivered in a black box with illustrations and brief characteristics printed on it. The design seems to be quite standard, but the skull on the logo immediately attracts attention.
The kit includes the headphones themselves, a charging case, instructions, a USB-USB Type C charging cable 25 cm long, documentation and a warranty card, as well as two pairs of interchangeable silicone tips (another one is installed on the headphones initially).
The ear pads are quite low, the manufacturer’s logo is applied on the outer side. The seam at the bottom is clearly visible in the photo, but in life it is not striking. The mount is standard, it is quite possible to pick up a replacement in case of loss.
Design and construction
The headset is available in several colors. From bright and unusual blue, mint and dark red to classic gray and black. We had a blue version for testing.
Case is far from the most compact of those that we have seen – 78×38×34 mm. You can’t put it in your pocket, but in a small handbag – easily.
The manufacturer’s logo is applied on the front of the cover, below it there are four LED indicators of the battery charge and a button to activate them. The latter is painted orange and stands out noticeably against the general background, adding originality to the design.
There is nothing interesting on the top of the lid – just a painted matte surface. Which, by the way, is not at all prone to the appearance of traces from touches.
At the bottom, many icons of various certification systems, brief information about the manufacturer, and so on are found at once. At the same time, they are applied with a slightly darker paint of the same color, they are not noticeable from afar and do not violate the integrity of the design.
At the bottom of the back of the case is a USB Type C port for charging, above it you can see the lid fastening loop. The case is assembled well – there are no gaps or backlashes.
The lid opens without any extra effort, is fixed by a “closer” in the extreme positions. The name and model number are printed on the inside, as well as an indication that the device was made in Vietnam.
The earphones are held securely inside with a magnetic attachment. At the same time, it is not difficult to get them, you just need to pull a little on the rather strongly protruding part of the case towards you, as they “pop out” of their slots.
Spring-loaded charging contacts are visible inside the headphone slots. They are placed in a kind of “wings” and not very deep – if necessary, they will be easy to clean. This, of course, can hardly be called a serious advantage of the headset in question, but the detail is quite pleasant.
The body of the headphones is not very large, in the ears they look quite neat. Weight is also small – only 5 g.
Ergonomic shape of the inner part of the case provides a good support on the ear cup, which makes the fit of the headphones comfortable and secure – we will return to this.
A logo is applied to the outer side of the case, but this is done in the most discreet manner – if you wish, you can notice it, but it will not be striking.
The outer panels of the case are buttons that are pressed easily and with a pleasant click, we will also return to them in the corresponding chapter.
On the protrusions of the inside of the case, you can see the contacts for charging and the barely noticeable designations of the right and left earphones – it will obviously be more convenient to navigate by the shape and position in the case.
LED mode indicators are located on the side, which is very good: they are perfectly visible when the headphones are in the case, and almost invisible while wearing.
On the opposite edge of the case are rather large holes for microphones for voice communication.
When viewed from the side, it is clearly seen that the sound guide is not very long and exits the housing at an angle. We have already talked about logos on silicone tips – the element seems to be simple and inconspicuous, but somehow more interesting with it.
Silicone tips are easy to remove and put in place, but they are held quite firmly due to the recess on the tip of the sound guide.
The sound guide output is covered with a thin plastic mesh, which is almost flush with its body – it will be more or less easy to clean.
After removing from the case, the headphones look for “familiar” sound sources for some time, if they do not find them, they activate the pairing mode. Well, then everything is as simple as possible – we find them in the corresponding gadget menu and connect them. The headset notifies you of connection and other events by voice messages in English.
Multipoint Skullcandy Sesh Evo does not support, which was verified by trying to connect it to a smartphone and PC running Windows 10 in parallel. At the same time, using the Bluetooth Tweaker utility, a list of supported codecs and their modes was obtained. The result is the standard for a good budget headset: a basic SBC, plus a slightly more “advanced” AAC.
Each headphone can be used in mono mode by simply placing the other in the case. Switching occurs in a “seamless” mode – the music continues to play in the rest. The reverse transition to stereo mode is also fast and without interrupting the playback track. When watching the video, there was no “out of sync” picture and sound, but in games it is quite noticeable. It should also be noted that Skullcandy has its own application for managing headsets – Skullcandy App, but the budget Sesh Evo does not support it.
The headset is controlled by buttons located on the outside of the case. They are pressed with a pleasant click and light enough not to “press” the headphones into your ear until discomfort appears. It may not be the most “advanced” option today, but it is definitely better than the poorly performing sensors in a lot of budget headsets that we have come across.
Multi-tap is supported, with which you can not only control playback and skip tracks, but also adjust the volume, activate voice assistants and even switch between three built-in equalizer presets. Presses are registered quite correctly, it only takes a little time to adapt to how quickly the button should be pressed.
In mono mode, some control options are lost. So, for example, if the user left the right earpiece working, only increasing the volume and scrolling the track forward will be available to him. If left – respectively, decrease and scroll back.
The fit of the Skullcandy Sesh Evo is quite secure and comfortable, but peculiar – they should be placed in the ear with a “twisting” movement, each time looking for the most comfortable position. Then it will be better with the transmission of the low-frequency range, and the headphones will hold well. If everything is done correctly, they do not fall out even with sudden movements during various activities, including jumping rope and twisting on an incline bench. Well, thanks to IP55 dust and water protection, you can not be afraid not only of sweat drops, but also of heavy rain while jogging – in general, the headphones are perfect for sports.
As mentioned above, the headset has three built-in equalizer presets, switching between them by pressing the control keys four times: Music, Podcast and Movie. We will talk about the features of the sound of headphones in each of them in the corresponding chapter. Also among the interesting features of the headset should be noted compatibility with the Tile service, which helps to find a lost gadget. It is enough to add the device to the service, and then click on the search button, as it “responds” with a rather loud sound, it will become much easier to find it. For those who often rush around the house in search of a headset left in an incomprehensible place, this can be a highly sought-after opportunity.
The quality of the built-in microphones for voice communication is average. In a quiet environment, they still cope with the task, but as soon as even a small background noise appears, the interlocutors begin to complain that it becomes much more difficult to make out speech. In general, everything is like with many headsets in the budget segment – you can exchange a few words, but for longer communication it would be better to look for a more serious solution.
In this test, we tried out a methodology for testing the autonomy of wireless headphones, which we will refine and develop in the future. Most often, manufacturers indicate a certain average operating time of headsets from a single charge, without mentioning the conditions in which the measurements were taken – in particular, the volume level, depending on which the result can vary significantly. Fixing this parameter was the first priority.
The safe sound pressure level when listening to music on headphones is 75 dB – one could take it as a guideline. But in practice, most listeners prefer a level in the region of 90-100 dB. Let’s take the average value – 95 dB, and we will take measurements on it. We broadcast white noise into the headphones, fix the SPL level at a given value, immediately after the start we start recording the signal from the measuring stand – by the length of the resulting track, it is easy to understand how long each of the headphones worked.
Claimed operating time – 5 hours. Approximately so much and worked headphones in each of the three tests.
It takes about an hour to fully charge the earphones from the case, the case itself charges longer – about 2 hours. The battery in the case is enough for 3 full charges of the headphones, plus once again it is possible to charge them by about 60 percent. The manufacturer claims 24 hours of total autonomy – you can count on this figure. Fast charging is supported: 10 minutes in the case should give a little more than two hours of headset operation. Our result turned out to be more modest, but not by much – 1 hour 43 minutes on average.
Sound and frequency response measurements
In marketing materials, the manufacturer promises “powerful sound with enhanced bass and clear high frequencies.” In general, everything is so, although not without reservations. The volume margin is indeed quite impressive, but the low-frequency range, although forced, is slightly prone to “buzz” – this is especially noticeable in tracks with dense bass drum parts. The correct selection of ear pads can significantly reduce the severity of this effect, but not get rid of it completely. However, experimenting in any case is worth at least in order to achieve more surround sound in the low-frequency range.
The middle is worked out rather poorly, the accentuated bass periodically leads to a decrease in the detail of the vocals and parts of the solo instruments. The high-frequency range, although well developed, periodically reminds of itself with the so-called “sand” and problems with sibilants. In general, the sound is rather modest, a little brightness and volume would obviously not hurt him. But for its price range, the Skullcandy Sesh Evo sounds pretty good. At this point, let’s leave subjective impressions and move on to the frequency response graphs.
We draw the attention of readers to the fact that the frequency response graphs are provided solely as an illustration, which allows us to demonstrate the main features of the sound of the tested headphones. You should not draw conclusions from them about the quality of a particular model. The actual experience of each listener depends on many factors, ranging from the structure of the hearing organs to the ear pads used.
The frequency response graph above is shown against the background of the IDF (IEM diffuse field compensation) curve provided by the manufacturer of the test bench used. Its task is to help compensate for the resonant phenomena in the simulated auditory canal and the features of the equipment used, creating a “sound profile” that most correctly illustrates how the sound of the headphones is perceived by the listener. It can be thought of as a device-specific analogue of the so-called “Harman Curve” created by the Harman International team led by Dr. Sean Oliva. Compensate the resulting frequency response graph in accordance with the IDF curve.
The peak in the upper midrange of the target curve is intended to compensate for resonances in the simulated ear canal. In this case, they turned out to be not so pronounced, which gave us a visible dip on the compensated chart – we should not take it too seriously. In other respects, the shape of the graph is quite consistent with the subjective impressions of listening to the headset. Well, in the end, let’s look at the results obtained by activating all three equalizer modes.
The main measurements were, of course, made with the Music profile activated. In Podcast mode, the main emphasis is predictably placed on the midrange, and the bass is almost completely relegated to the background. In Movie mode, the differences in sound are minimal – only the high-frequency range is slightly emphasized, and a little reverb is added.
