Good · researched from 3 sources
Nearly sixty hours of battery and genuinely comfortable pads for under a hundred, with cancelling that works best on the noise you notice least. The sound is the compromise, and the twelve-band app is where you start fixing it.
- Buy if
- Very long trips, on a measured 56 hours · Offices and cafés, where the treble cancelling is strongest · Anyone who wants marathon comfort at a budget price
- Skip if
- Aircraft and trains, where 15.6 dB of low-frequency reduction is modest · Critical listening, on TechGearLab's 6.4 sound score · Gym use, since there is no water resistance
We don’t list prices, because Amazon’s change hourly.
Fifty-seven hours
SoundGuys measured 56 hours 51 minutes with cancelling on, against a claim of 50.
TechGearLab measured exactly 50. Trusted Reviews' spot check, at roughly five hours of use per ten percent of battery, lands at about the same.
Whichever figure you take, this runs for the better part of a fortnight of commuting between charges, and five minutes on the cable returns five hours, which is the fastest quick-charge result anywhere in this catalogue.
Where the cancelling works
TechGearLab's breakdown is the most useful measurement here: 24 dB overall, composed of 15.6 dB at low frequencies, 21.0 in the midrange and 36.2 in the highs.
That shape is the opposite of what buyers usually assume. Most people picture noise cancelling as the thing that removes an aircraft's drone, and the low frequency figure here is modest. What 36.2 dB in the treble buys you is chatter, keyboards, air conditioning whine and the general hiss of a shared office.
SoundGuys describes the same product more favourably, crediting it with nulling low rumble below 1 kHz on public transit with passive isolation handling the rest.
Both fit if you read the 15.6 dB as adequate rather than absent.
The sound is the compromise
TechGearLab: 6.4 out of 10, underemphasised mids and treble.
SoundGuys: a little light in the low end against their target curve, with a significant boost around 150 Hz when used wired.
Trusted Reviews: warm, emphasising mids and bass, with the low end blurring together and highs falling flat on vocal tracks.
Three descriptions that do not agree with each other, from headphones costing under a hundred. What they have in common is that nobody calls the sound a strength.
The app has twelve presets and a graphic equaliser with three custom profiles, which is more adjustment than most headphones at any price, and it is the obvious first move.
Comfort is the quiet win
TechGearLab: 7.3 out of 10, 7.5 hours of comfortable listening, super cozy, good for marathon sessions.
Trusted Reviews: thick memory foam under protein leather, 250 grams, soft and comfortable for extended wear.
SoundGuys dissents, criticising a heavy headband and low clamping force. Low clamp is generally why headphones stay comfortable, so that reads more as an observation than a fault.
The gaps
No water resistance at all, which Trusted Reviews raises for anyone thinking about the gym.
TechGearLab reports multipoint needing frustrating workarounds when pairing with several devices.
Trusted Reviews finds the transparency mode too quiet to hold a conversation through, and the physical buttons clicky and hard to tell apart.
And SoundGuys notes there is no continuous power or connection indicator, so knowing whether they are on is guesswork.
How it scored
The overall 8.0 is the weighted average of these five criteria — we never adjust it by hand.
Sound quality
TechGearLab scored sound 6.4 out of 10 with underemphasised mids and treble. SoundGuys measured a response a little light in the low end. Trusted Reviews finds the bass blurring together.
Value
SoundGuys scored 7.6 out of 10 and calls it an excellent budget option. TechGearLab scored 66 out of 100 and Trusted Reviews four stars, both explicitly on price.
Build quality
SoundGuys criticises a heavy headband and low clamping force, and notes there is no continuous power or connection indicator. Trusted Reviews notes there is no water resistance.
Comfort
TechGearLab scored comfort 7.3 out of 10 and puts comfortable listening at 7.5 hours. Trusted Reviews credits thick memory foam and protein leather at 250 g.
Noise cancelling
TechGearLab measured 24 dB overall, breaking down to 15.6 low, 21.0 mid and 36.2 high, and calls it one of the best budget implementations while short of premium models.

How we researched this
We have not had this unit on the bench. This review synthesises the manufacturer’s published specifications, independent measurements and owner reports listed below. Every figure on this page comes from one of those sources rather than our own measurement.

sources reviewed
SoundGuys supplies the measured battery figure, the frequency response finding against their target, the weight, the app inventory and the build criticisms, and scored 7.6 out of 10. TechGearLab tested against a group and supplies the noise cancelling attenuation by frequency band, the category scores, a second battery measurement and the comfort duration, scoring 66 out of 100. Trusted Reviews supplies the driver detail, the codec and multipoint information, the real-world battery observation and the transparency mode criticism, and gave four stars. The sources differ on codec support and on call quality, and both positions are reported.

Sonarworks measured up to ±4 dB of channel imbalance and ±3 dB of bass variation between units. That is a bigger difference than most of the arguments about how it sounds.

One lab scored comfort 4.6 out of 10 and found glasses cut wearable time to less than sixty minutes. Everything else about them is very good, which is the frustrating part.

Measured runtime came in at 5 hours 43, 6 hours 03 and 8 and a half hours depending on who ran the test. The noise cancelling has a hole in it at 1kHz that only one of them looked for.
