The TREBLAB Z2 Wireless are ANC Bluetooth over-ears with 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.
The TREBLAB Z2 are fair 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 many phone calls, as their microphone makes your voice sound unnatural and distorted.
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 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 consistent among various users, and you should experience their sound reproduction similarly every time you wear them.
The TREBLAB Z2 are fair for commute and travel. They're decently comfortable, come with a good hard carrying case, and their battery lasts nearly 20 hours, which is good for long trips. Unfortunately, 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.
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.
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 don't block out much background noise, and their shallow ear cups make them uncomfortable when used for extended periods. On the bright side, their 20-hour battery means they should easily last a couple of full workdays.
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.
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. We only test the integrated microphone, so we don't know how well the in-line mic performs.
The TREBLAB Z2 are mediocre for phone calls. The integrated microphone makes your voice sound thin, unnatural, and very distorted. It does a disappointing job separating your voice from background noises. It's worth noting that we only test the integrated microphone, so we don't know how well the in-line mic performs.
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. If you're looking for more comfortable headphones from this manufacturer, check out the TREBLAB Z7 Pro Wireless instead.
The TREBLAB Z2's controls 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. This is disappointing as the in-line remote is more difficult to use and 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, they 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 protect against scratches, drops, and light water exposure.
The TREBLAB Z2's build quality 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.
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 aren't the best option for the gym.
The TREBLAB Z2's sound profile is well-balanced and accurate, making them well-suited for a very wide range of content and genres. That 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 TREBLAB Z2's bass range is very accurate. While most of the range is underemphasized, it's even and flat without any major sharp dips or peaks. Unfortunately, they 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 TREBLAB Z2's mid accuracy is outstanding. 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 TREBLAB Z2's treble range 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 TREBLAB Z2's peaks and dips performance 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 is sub-par. 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 TREBLAB Z2's soundstage is disappointing. 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.
These headphones don't have any virtual soundstage features.
The TREBLAB Z2's weighted harmonic distortion performance is decent. Almost all frequencies fall within acceptable limits, resulting in a fairly clear and pure audio reproduction.
These are the settings used to test the TREBLAB Z2. Our results are only valid when used at these settings.
The TREBLAB Z2's noise isolation performance is sub-par. While these headphones have an ANC feature, it doesn't work very well and only slightly lowers low-end sounds like engine rumbles. 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 have a mediocre leakage performance. The leakage occupies a fair amount of the mid and treble ranges, so the sound leaking from your headphones will be 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 TREBLAB Z2 have an integrated microphone as well as an in-line mic on the included analog cable. We only test the integrated mic, and the in-line mic may perform differently.
The recording quality of the TREBLAB Z2's integrated microphone is sub-par. When using the microphone, your voice sounds very unnatural, thin, and distorted.
The integrated microphone is middling at handling background noise. It's best suited for quiet environments, as your voice gets easily drowned out in noisy situations.
The overall battery performance 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, you can use them passively with their included 1/8" audio cable.
These headphones don't have a dedicated companion app.
The Bluetooth connectivity is good. They can connect to two devices at a time, so you can easily switch between them. While their SBC latency on PC is high, they support aptX-LL for a much lower latency connection, provided the device you're 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 only support a wireless connection via Bluetooth.
These headphones come with a Micro-USB cable for charging and 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.
Thanks to the in-line mic on their wire, these headphones are fully compatible with PC or PS4 gaming when you use them wired. They're also compatible wirelessly with any Bluetooth-enabled PC, though you may experience too much lag for competitive gaming.
Thanks to the in-line mic on their wire, these headphones are fully compatible with Xbox One when you use them wired into the controller.
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 they have a much better-balanced sound profile.

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.
The TREBLAB Z7 Pro Wireless are better headphones than the TREBLAB Z2 Wireless. The Z7 are more comfortable and better-built, and their noise isolation performance is significantly better. They also have a superior battery performance, and they also support aptX HD. However, the TREBLAB Z2 support aptX-LL and have a more neutral sound profile, which some users may prefer.
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.
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. On the other hand, the TREBLAB have a better-balanced sound profile, support multi-device pairing, and last a tiny bit longer off a single charge.
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.
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.
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.
