TREBLAB Z7 Pro Wireless Headphones Review

The TREBLAB Z7 Pro have a fairly non-descript look. They're black with a satin finish and, unlike the TREBLAB Z2 Wireless, lack the manufacturer's logo on the ear cups. Overall, they have a similar design language to the Sony WH-1000XM4 Wireless but look shinier, which some may find cheap and plasticky.

The TREBLAB Z7 Pro have a comfortable fit. They have well-padded ear cups that don't clamp on your ears too tightly, so you can wear them for long periods without feeling discomfort. If you have large ears, they may touch the edges of the inner ear cup padding.

The TREBLAB Z7 Pro have good controls. All the controls are on the right ear cup, and there are three buttons and a touch-sensitive surface. These headphones also have an auto-pause feature that pauses your audio when you take the headphones off your head. It's very sensitive, though, so if you lift the ear cup to adjust their fit, you can accidentally trigger this feature. There's also no way to turn this feature off. That said, the controls are smooth, easy to use, and responsive.

Using the touch-sensitive surface:

• Swipe up: Raises the volume.
• Swipe backward: Skips the track backward.
• Swipe forward: Skips the track forward.
• Double tap: Plays and pauses audio. Also answers and ends calls.
• Tap and hold: Activates voice assistant. Also rejects calls.
• Cover ear cup with your hand: Activates transparency mode so that you can hear what's going on around you without taking off your headphones.

ANC button:

• Single tap: Cycles between ANC on, transparency mode, and ANC off.

Power button:

• Single tap: Tells you your battery life.
• Press and hold for three seconds: Powers the headphones on and off.

Bluetooth button:

• Press and hold for three seconds: Enters pairing mode.

The TREBLAB Z7 Pro have mediocre portability. Although they're a bit bulky, the ear cups can swivel and fold inwards to help conserve space. They also come with a carrying case to help protect them when you're on the go.

The TREBLAB Z7 Pro have a good carrying case. It's a bit big, but it feels sturdy and solid. There's a velcro pouch inside the case, where you can store the cables when not in use.

The TREBLAB Z7 Pro have good build quality. They're mostly plastic with faux leather padding. The padding feels soft and good against the skin, but the thin coating on the outer ear cup is prone to slight rips or tears over time. On the upside, they're certified IPX4 for resistance against water splashes, which is a bit uncommon for over-ear headphones.

These headphones have good stability. Although they don't have a tight clamping force, they won't fall off your head with low-intensity head movements. However, they can move around with more intense head movements, so you need to be cautious if you want to wear them during your workout.

The TREBLAB Z7 Pro have a very excited sound profile that delivers extra thump, rumble, and boom to mixes. At the same time, vocals and lead instruments are bright. However, their overemphasized bass muddies and clutters your tracks while sibilants are piercing and harsh. Unfortunately, these headphones lack sound customization features like an EQ to help you adjust their sound to your liking.

The TREBLAB Z7 Pro have very good frequency response consistency. They have consistent bass delivery, but they're more prone to inconsistencies in treble delivery due to positioning and seal. However, once you can get a good fit, you'll get more consistent audio delivery.

The TREBLAB Z7 Pro have sub-par bass accuracy. The whole range is very overemphasized, resulting in intense thump, punch, and boom, which is great for genres like EDM and hip hop. However, this sound can also sound muddy and cluttered.

The mid accuracy is fair. There's some overemphasis from the bass range into the low-mids, which muddies mixes. Although the mid-mid is fairly flat, the high-mid is overemphasized. Vocals and lead instruments like the electric guitar in the chorus of Beggin' by Måneskin sound harsh.

The TREBLAB Z7 Pro have alright treble accuracy. Overall, the range is overemphasized. The upper harmonics of vocals and lead instruments are harsh and piercing, while sibilants like cymbals are painful.

The TREBLAB Z7's peaks and dips performance is okay. A peak in the high-bass adds boom to mixes, while a dip in the low to mid-mid pushes vocals and lead instruments to the back of the mix. The peak in the high-mid leads to a peak in the low-treble that's more prominent in the right driver. It makes vocals and lead instruments piercing. A massive peak in the high-treble makes sibilants, like S and T sounds, piercing.

The imaging performance is great. The group delay falls below the audibility threshold, resulting in tight bass and transparent treble reproduction. The L/R drivers are also well-matched in amplitude and phase response, ensuring a stable and balanced stereo image. Although there are a couple of peaks in the phase response, you won't hear the peak in the low-bass range. The peak in the high-treble range is also very hard to hear with real-life content. Keep in mind that there's a slight mismatch in frequency response, resulting in a small difference in level between the left and right drivers. That said, imaging can vary between units and indicate a manufacturer's quality control and ergonomics.

The TREBLAB Z7 Pro have a poor passive soundstage performance. They're closed-back headphones, so their passive soundstage doesn't seem very open or spacious, especially when compared to that created by open-back headphones. Their soundstage seems wide but a bit unnatural, as if sound is coming from inside your head rather than from speakers placed in the room around you.

The TREBLAB Z7 Pro have a decent weighted harmonic distortion performance. There's a small peak between the low and mid-treble at normal listening volumes, but this can be hard to hear with real-life content. As a result, most frequencies fall within good limits, which results in fairly clear and pure audio reproduction.

These are the settings used to test the TREBLAB Z7 Pro. Our results are only valid when used in this setting. Note that these headphones have a very sensitive ear detection sensor. When placed on our dummy head, the headphones automatically pause audio. To get around this, we used a piece of copper tape and wire inside the ear cup to activate the sensor. However, this isn't a problem for human ears, and you won't experience this issue with regular use.

The TREBLAB Z7 Pro's noise isolation performance is great. While they do an alright job blocking out the low rumble of bus engines, they're more effective when it comes to office chatter and the high-pitched hum of computer fans.

The TREBLAB Z7 Pro have a decent leakage performance. Escaping audio is mostly concentrated in the mid-range and sounds fuller than that of in-ears and earbuds. If you're listening to audio at a high volume in a moderately noisy office, it's unlikely you'll bother others around you.

The TREBLAB Z7 Pro's mic has poor recording quality. In our original testing, we noticed that the mic's frequency response was all over the place when using aptX HD codec. When retested using the PC's integrated Bluetooth, rather than our Bluetooth dongle, and using SBC, which is the default Bluetooth codec, we could get more consistent results. However, the overall recording quality didn't improve much when switching to SBC. As a result, your voice sounds thin and lacking in body, which can make it challenging for whoever you're speaking with to hear you clearly.

The mic's noise handling performance is disappointing. Although the manufacturer advertises the mic to have electronic noise cancelling (ENC), which is supposed to reduce background noise picked up by the mic, it doesn't seem to make a difference in its performance. Like the Recording Quality test, we also reran this testing using the SBC codec instead of aptX HD, which is the codec used for the sound portion of our review. However, the mic performance in this regard didn't change. It still struggles to separate your voice from moderate ambient noise around you. Your voice can be drowned out if you're calling from a busy street.

The TREBLAB Z7 Pro's battery performance is great. The manufacturer advertises them to have 30 hours of continuous battery life, and we measured almost 38 hours, which will easily last through long days on the go. They also have a 20-minute quick charge feature that they advertise to supply five hours of playback. If you run out of battery life, you can use them passively using their 1/8" TRS cable. Keep in mind that battery life can vary with real-life use, though.

These headphones have great Bluetooth connectivity. They support multi-device pairing, meaning you can connect them with your laptop and smartphone at the same time. Although they support aptX and aptX HD codec, they have high latency across all support codecs on PC, so you may notice your audio and visuals fall out of sync. On the upside, the latency on iOS and Android devices is a lot lower, which is good if you like to stream video from your phone. It's worth noting that devices and apps compensate for latency differently, so your mileage may vary.

These headphones come with a 1/8" TRS cable that you can use for audio. However, unlike the TREBLAB Z2 Wireless, this cable doesn't have an inline mic. These headphones also come with a USB-A to USB-C cable for charging them up.

These headphones are fully compatible with PCs via Bluetooth. If you connect them to your PC using their 1/8" TRS cable, you can only receive audio and can't use their mic.

The TREBLAB Z7 Pro are audio-only compatible with PlayStation consoles via their 1/8" TRS cable.

You can use these headphones on Xbox consoles via their 1/8" TRS cable. However, you can only receive audio.
