The TREBLAB Z2 are ANC Bluetooth over-ears that have a fairly well-balanced sound profile, making them versatile enough for most genres, though they lack a bit of brightness and rumble. They feel decently well-built and comfortable, though unfortunately, their shallow ear cups may get uncomfortable during longer listening sessions. While they have ANC, it doesn't do much, and their microphone makes your voice sound very distorted and unnatural. On the bright side, they last nearly 20 hours off a single charge, and they support multi-device pairing and aptX-LL.

Our Verdict

6.9 Mixed Usage

The TREBLAB Z2 are decent headphones for mixed usage. They have a fairly well-balanced sound profile and last nearly 20 hours off a single charge. They feel decently well-built and comfortable, though their shallow ear cups may cause discomfort during longer listening sessions. Unfortunately, their ANC feature doesn't work very well, and they do a sub-par job at blocking out background noise. They also aren't the best choice if you make a lot of phone calls, as their microphone makes your voice sound unnatural and distorted.

Pros
  • Fairly well-balanced and versatile sound profile.
  • Very good 20-hour battery.
  • Easy to use physical controls.
  • Low latency on some Bluetooth devices thanks to aptX-LL support.
Cons
  • Microphone performance is disappointing; voices sound very distorted and unnatural.
  • Shallow ear cups may get uncomfortable during extended use.
  • Disappointing ANC performance.
  • Leak a fair amount of audio.
7.6 Neutral Sound

The TREBLAB Z2 are a good option for neutral sound listening thanks to their fairly well-balanced sound profile. While most of the ranges are quite even and flat, their bass range is a bit recessed, which may be disappointing to some people. They also lack a bit of brightness, and some higher frequencies sound dull and lispy. On the bright side, they're quite consistent among various users, and you should experience their sound reproduction similarly every time you wear them.

Pros
  • Fairly well-balanced and versatile sound profile.
  • Easy to use physical controls.
Cons
  • Shallow ear cups may get uncomfortable during extended use.
6.9 Commute/Travel

The TREBLAB Z2 aren't the best choice for commuting or travel due largely in part to their disappointing noise isolation. Their ANC doesn't work very well, so they don't help much with reducing the low rumble of a bus or plane engine. They also aren't the most comfortable during long listening sessions. On the bright side, they come with a good hard carrying case, and their battery lasts nearly 20 hours.

Pros
  • Fairly well-balanced and versatile sound profile.
  • Very good 20-hour battery.
  • Easy to use physical controls.
Cons
  • Shallow ear cups may get uncomfortable during extended use.
  • Disappointing ANC performance.
  • Leak a fair amount of audio.
  • Ear cups don't fold inwards for better portability.
7.1 Sports/Fitness

The TREBLAB Z2 are decent for sports if you prefer the fit of over-ears at the gym. They feel decently well-built and comfortable, and they have easy-to-use controls, so you can quickly change tracks mid-workout. They feel stable enough on the head for jogs and light exercising, though they'll likely fall off during more intense workouts or runs.

Pros
  • Very good 20-hour battery.
  • Easy to use physical controls.
Cons
  • Shallow ear cups may get uncomfortable during extended use.
  • Disappointing ANC performance.
  • Leak a fair amount of audio.
  • Ear cups don't fold inwards for better portability.
6.8 Office

The TREBLAB Z2 aren't the best option for use at the office. They leak a lot of audio, so your coworkers will likely get distracted when you listen to music at high volumes. They also don't block out very much background noise, and their shallow ear cups make them uncomfortable when using for extended periods. On the bright side, their 20-hour battery means they should easily last a couple of full workdays.

Pros
  • Very good 20-hour battery.
  • Easy to use physical controls.
  • Low latency on some Bluetooth devices thanks to aptX-LL support.
Cons
  • Shallow ear cups may get uncomfortable during extended use.
  • Disappointing ANC performance.
  • Leak a fair amount of audio.
5.4 Wireless Gaming

The TREBLAB Z2 aren't recommended for wireless gaming as they only support a wireless connection via Bluetooth. This means they aren't compatible with most modern consoles. While you can pair them to a mobile phone or PC, you may notice high latency depending on your device.

7.1 Wired Gaming

The TREBLAB Z2 are a decent option for wired gaming. Thanks to the in-line mic on the included audio cable, you can plug them into your Xbox One or PS4 controller and get full compatibility. It's worth noting that we only test the integrated microphone, so don't know how well the in-line mic performs.

Pros
  • Fairly well-balanced and versatile sound profile.
Cons
  • Shallow ear cups may get uncomfortable during extended use.
6.1 Phone Calls

The TREBLAB Z2 aren't recommended for phone calls. The integrated microphone makes your voice sound thin, unnatural, and very distorted. It also does a disappointing job of separating your voice from background noises. It's worth noting that we only test the integrated microphone, so don't know how well the in-line mic performs.

Pros
  • Easy to use physical controls.
  • Low latency on some Bluetooth devices thanks to aptX-LL support.
Cons
  • Microphone performance is disappointing; voices sound very distorted and unnatural.
  • Disappointing ANC performance.
  • Leak a fair amount of audio.

Design
Style

The TREBLAB Z2 have a fairly sleek and modern design. They look a lot like the similarly-priced Mixcder E9 Wireless, but with an etched white design on each ear cup. They're also available with a black logo on the earcups as opposed to white.

The TREBLAB Z2 are decently comfortable. They're lightweight and well-padded, but unfortunately, the ear cups are very shallow and your ears will likely get pushed in by them. They clamp the head a little bit, but not enough to be exceptionally uncomfortable during most listening sessions.

The controls for the TREBLAB Z2 are decent. The physical buttons are easy to use and provide a good amount of feedback, so you know when you've issued a command. The controls are on the right ear cup, and the middle button has a raised dot, so you can easily tell which button you're resting on without looking. The headphones also give you an audio cue when you reach max volume, and you get a good amount of functionality, including media/call control, and volume control. When using the headphones with the included analog 1/8" cable, the ear cup controls no longer function and all inputs are done via a single button on the in-line remote/mic, which is a bit disappointing as the in-line remote is more difficult to use, and it doesn't provide track skipping or volume control.

The TREBLAB Z2 aren't the most portable as the ear cups don't fold inwards into a more compact shape. On the bright side, the ear cups can swivel to lay flat, making them more comfortable around your neck and easier to fit into luggage or bags.

The TREBLAB Z2 come with a good hard carrying case to help protect them while traveling. It should provide protection against scratches, drops, and light water exposure.

Build Quality

The build quality of the TREBLAB Z2 is decent. The entire headphones are made out of solid plastic, with a bit of metal enforcing the headband. While they don't look as premium and high-end as more expensive options, they don't feel especially cheap or plasticky either.

7.0
Design
Stability

These headphones are decently stable. They clamp the head enough to keep them on during light jogs and head movements. They shouldn't move too much if you have to quickly run to catch a bus, but likely aren't the best option for taking to the gym.

The sound profile of the TREBLAB Z2 is quite well-balanced and accurate, making them well-suited for a very wide range of content and genres. That being said, their underemphasized bass range may be slightly disappointing to fans of bass-heavy genres, and they also lack a bit of brightness which causes some instruments to sound dark and veiled.

The TREBLAB Z2 are very consistent between various users and reseats. Most people should experience their sound reproduction very similarly, though you may have to adjust them slightly on your head to hear their treble the same way every time you use them.

The bass range of the TREBLAB Z2 is very accurate. While most of the range is underemphasized, it's quite even and flat, without any major sharp dips or peaks. Unfortunately, they do lack a fair amount of bass in comparison to many popular headphones, like the Sony WH-1000XM3 Wireless or the Bose QuietComfort 35 II/QC35 II Wireless 2018.

The mid accuracy of the TREBLAB Z2 is excellent. Almost the entire range is even, flat, and accurate. This results in present and clear instruments and vocals that don't sound muddy, harsh, or distant.

The treble range of the TREBLAB Z2 is decently accurate. While half of low-treble is very accurate and even, it dips a fair amount started in the middle of low-treble, resulting in some higher frequency instruments sounding dull and lispy. High treble is also quite uneven, which may cause some sounds to be piercing and others to be very dull, though this is at high enough frequencies that it generally isn't audible to most people.

The peaks and dips performance of the TREBLAB Z2 is very good. Most of the ranges are fairly even, without too many sudden spikes. The peak in high-bass causes the headphones to sound a bit boomy in comparison to the underemphasized low and mid-bass ranges, though this isn't too noticeable overall. However, the large dip in mid-treble causes some frequencies to be noticeably dull and lispy, making the headphones lack a bit of brightness.

The imaging performance of these headphones is disappointing. While most of the group delay is well beneath the audibility threshold, it crosses over in low-bass, resulting in a transparent treble reproduction but a loose bass range. Our L/R drivers are decently well-matched and while their phase mismatch score is very bad, this is because the drivers are mismatched at a very low frequency that likely won't be noticeable to anyone. It's also worth noting that these results are only valid for our unit, and yours may perform differently.

The soundstage of the TREBLAB Z2 is poor. While the soundstage appears decently natural, and very large, it isn't very open and sounds feel to be inside your head as opposed to in front. However, this is to be expected of closed-back headphones.

The noise isolation performance of the TREBLAB Z2 is disappointing. While these headphones have an ANC feature, it doesn't work very well, and only slightly lowers low-end sounds like engine rumbles or construction noises. They do a decent job at blocking out background chatter, though most of this is done passively simply by physically blocking your ears. They do a good job of isolating out higher-pitched frequencies, like the sound of a fan or AC unit, though again, this is almost entirely done passively.

The TREBLAB Z2 leak a fair amount of sound. The leakage occupies a fair amount of the mid and treble ranges, so the sound leaking from your headphones will be quite full. It nears the top of the noise floor of an average office, so your coworkers will likely hear a fair amount of what you're listening to.

The overall battery performance of these headphones is good. They last almost 20 hours off a single charge with ANC turned on, which is very good. While they're advertised as lasting up to 30 hours, this may be with ANC turned off. Unfortunately, they take over four hours to fully charge, which is a long time. On the bright side, they can be used passively with their included 1/8" audio cable.

The Bluetooth connectivity of these headphones is very good. They can be connected to two devices at a time, so you can easily switch between them. While their SBC latency on PC is quite high, they support aptX-LL for a much lower latency connection, provided the device your connecting to supports it. While watching YouTube videos on a mobile device, they have high latency on iOS, but very low latency on Android devices. It's worth noting that devices and apps tend to compensate for latency differently, so your mileage may vary.

These headphones come with a Micro-USB cable for charging, as well as a 1/8" TRS to TRRS analog cable for a wired connection. Because the cable is only TRS on the end that plugs into the headphones themselves, it doesn't support input from the controls on the ear cups or the integrated microphone, requiring you to use the in-line remote and mic while wired. On the bright side, both included cables are flat silicone cables, which tend to be less prone to tangles and kinks.

Compared to other headphones

Comparison picture

The TREBLAB Z2 are decent over-ear headphones that don't offer much over the competition. Their ANC performs much worse than the similarly-priced Mixcder E9 Wireless or Anker Soundcore Life Q20 Wireless, though, on the bright side, they have a much better-balanced sound profile. If you don't want to spend over $100 but want something that performs better, check out our recommendations for the best wireless headphones under $100, the best noise cancelling headphones under $100, and the best over-ear headphones under $100.

The TREBLAB Z2 Wireless are better headphones for mixed usage than the Cowin E7 Wireless. The TREBLAB feel more comfortable and durable, have easier to use controls, and support multi-device pairing. Their sound profile is also much better-balanced, with a much more accurate treble range. On the other hand, the Cowin last longer off a single charge, and have a slightly better ANC feature, though neither headphones block very much background noise.

Cowin E7 Pro Wireless
SEE PRICE
Amazon.com

The TREBLAB Z2 Wireless are slightly better headphones than the Cowin E7 Pro Wireless. The TREBLAB are more comfortable, and feel better-built. They also have a much more accurate sound profile that doesn't sound as boomy and muddy. On the other hand, the Cowin have a much better ANC feature, and they also last a lot longer off a single charge.

Sony WH-1000XM3 Wireless
SEE PRICE
Amazon.com

The Sony WH-1000XM3 Wireless are much better headphones than the TREBLAB Z2 Wireless. While both headphones have well-balanced sound profiles, the Sony is a bit more bass-heavy, without being overpowering. They also look and feel much more premium and well-built, are a lot more comfortable, last longer off a single charge, and have an excellent companion app that gives access to a graphic EQ. Sony's ANC is also among the best we've ever tested, while the TREBLAB's ANC doesn't do much at all. On the other hand, some people may prefer the physical controls on the TREBLAB, and they may represent better value to some.

Mpow H10 Wireless
SEE PRICE
Amazon.com

The TREBLAB Z2 Wireless and the Mpow H10 Wireless are similarly-performing headphones. The Mpow are more comfortable, last longer off a single charge, and have a better microphone. Their ANC feature is also significantly better and blocks out much more background noise. On the other hand, the TREBLAB have a much better-balanced sound profile, support multi-device pairing and aptX-LL, and come with an analog cable with an in-line microphone.

Mixcder E9 Wireless
SEE PRICE
Amazon.com

The Mixcder E9 Wireless are marginally better headphones than the TREBLAB Z2 Wireless. The Mixcder are more comfortable, have a better mic, and have much better ANC.

Anker Soundcore Life Q20 Wireless
SEE PRICE
Amazon.com

The Anker Soundcore Life Q20 Wireless and the TREBLAB Z2 Wireless both perform similarly overall. While the Anker have a much better ANC feature and last longer off a single charge, the TREBLAB have a better-balanced and less bass-heavy sound profile. The Anker are more comfortable and have a better microphone. On the other hand, the TREBLAB support features like multi-device pairing and aptX-LL, and have easier to use controls.
