The TREBLAB Z7 Pro are mid-end hybrid active noise cancelling (ANC) headphones. Unlike the TREBLAB Z2 Wireless, which are this brand's only other over-ears, their ANC activates when it detects noise, and the headphones automatically pause your audio when you take them off of your ears. These over-ears also support aptX and aptX HD codecs, which help lower latency and improve audio quality, as well as multi-device pairing with up to two devices at a time.

Our Verdict

6.4 Neutral Sound

The TREBLAB Z7 Pro are mediocre for neutral sound. They have a very excited sound profile that delivers intense thump, rumble, and boom while vocals and lead instruments are bright. However, their sound is still very muddy and piercing. They also lack sound customization features, so you can't adjust their sound to your liking. On the upside, they have consistent audio delivery, so long as you take the time to adjust their fit and positioning on your head when you use them. They also support aptX and aptX HD codecs, which help lower latency and improve audio quality when streaming over Bluetooth.

Pros
  • Comfortable, well-built design.
  • aptX and aptX HD support.
Cons
  • No EQ.
  • Poor passive soundstage performance.
7.6 Commute/Travel

The TREBLAB Z7 Pro are good for commute and travel. These comfortable headphones have an ANC system that can block out the low rumble of bus and plane engines fairly well, although it does an even better job of cutting down passenger chit-chat. They also have over 37 hours of continuous battery life, and you can use the headphones wired if you run out of battery life. Although they have a bulky design, they come with a carrying case to help protect them when you're on the go.

Pros
  • ANC offers great overall noise isolation performance.
  • Comfortable, well-built design.
Cons
  • No EQ.
7.3 Sports/Fitness

The TREBLAB Z7 Pro are decent for sports and fitness. Unlike most over-ears on the market, these headphones have an IPX4 rating, meaning they can resist water splashes. They have a comfortable as well as durable design that won't move around on your head during moderate head movements. However, they can fall off during more intense head movements.

Pros
  • Comfortable, well-built design.
Cons
  • Poor passive soundstage performance.
7.2 Office

The TREBLAB Z7 Pro are satisfactory for office use. These over-ears have a comfortable, well-built fit. Thanks to their ANC system, they can block out ambient chatter and the high-pitched hum of your computer fan. They also support multi-device pairing, so you can stay connected to your PC and smartphone at the same time and have over 37 hours of continuous playback time. However, if you need to take calls from the office or attend online meetings, their mic has a poor overall performance, so your voice sounds thin and muffled. Your voice can also be drowned out by moderate ambient noise.

Pros
  • ANC offers great overall noise isolation performance.
  • Comfortable, well-built design.
  • Supports multi-device pairing.
Cons
  • Mic has poor overall performance.
  • Poor passive soundstage performance.
5.1 Wireless Gaming

The TREBLAB Z7 Pro are Bluetooth headphones and can't connect to consoles that don't support Bluetooth. Their latency is also likely too high to be suitable for wireless gaming.

6.7 Wired Gaming

The TREBLAB Z7 Pro are okay for wired gaming if you don't need mic support. These headphones come with a TRS cable, which can only receive audio. If you don't mind this, they have a comfortable and well-built design. Their every excited sound profile can help deliver extra thump and boom to gameplay. However, dialogue and instruments sound muddy and piercing. These headphones also lack an EQ to help you adjust their sound to your liking.

Pros
  • ANC offers great overall noise isolation performance.
  • Comfortable, well-built design.
Cons
  • No EQ.
  • No mic support.
5.9 Phone Calls

The TREBLAB Z7 Pro are sub-par for phone calls. These headphones have an integrated microphone, but it offers poor overall performance. Your voice sounds thin, dark, and muffled. If you're taking a call in a noisy environment, your voice can be easily drowned out by background sound. On the upside, their hybrid noise cancelling system can block out a great amount of ambient noise so that you can focus on your call.

Pros
  • ANC offers great overall noise isolation performance.
Cons
  • Mic has poor overall performance.

  1. Updated Jul 14, 2022: After user feedback regarding the audio quality recording not matching the test score, we've retested the mic's Recording Quality and Noise Handling performance. The original review results used aptX HD codec, which resulted in inconsistencies in the mic's frequency response. However, we could slightly improve our results by using the SBC codec, and the mic's frequency response doesn't sound muffled.

Differences Between Sizes And Variants

The TREBLAB Z7 Pro come in one color variation: 'Black', and you can see our model's label here. If you come across another variant of these headphones, please let us know in the discussion section below, and we'll update our review.

Compared To Other Headphones

The TREBLAB Z7 Pro are hybrid noise cancelling headphones. Their noise isolation performance is on par with other similarly-priced mid-end over-ears like the Anker Soundcore Life Q35 Wireless, and they even do a better job of blocking out background sound than this manufacturer's other over-ears, the TREBLAB Z2 Wireless. They're also unique in that they have an IPX4 rating for resistance against water splashes, which is very uncommon for over-ear headphones. They don't have any sound customization features, so you can't adjust their very excited sound to better suit your tastes.

Build Quality

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.

Design
Stability

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'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 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.

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.
