Treblab Z7 Pro surprise with a warm yet balanced tuning, 39.5 hours long battery life, and excellent comfort. However, don’t expect a very detailed audio performance.
The Z7 Pro’s are a premium offering from Treblab, focusing on competing in the sub-$200 territory.
Audio enthusiasts will enjoy the headphones’ balanced, smooth sound, with an almost identical midrange as the Apple AirPods Max.
On the other hand, commuters will enjoy comfy memory foam earpads, beefy battery, and active noise cancellation, which can easily beat the one from the Sony WH-CH710N. More on that later.
However, for $120 (or even more in some cases), Treblab Z7 Pro could’ve still offered more.
Read our full review to find out what’s great and what are the headphones’ biggest downsides.
Z7 Pro have boosted bass, balanced midrange, and a smooth, rolled-off treble. That’s the fastest way to describe the sound signature. While their audio quality is pleasing to listen to, it lacks details and dynamics.

Treblab Z7 Pro Sound Quality Test – HeadphonesAddict
Most wireless headphones suffer from boosted and bloated bass since people perceive this as a fun sound.
Thankfully, Treblab Z7 Pro didn’t make the next Beats alternative but took a few tuning ideas from various headphones. Like the mid-range from Apple AirPods Max and treble smoothness from Sennheiser HD 650.
I’m talking about tuning, not technical performance, just to be precise.
The result is a very pleasing listening experience. But let’s dive into more details.
Treblab Z7 Pro Frequency Response
There’s no significant difference between ANC off/on and wired listening.
Bass: Boosted but controlled
Lower frequencies are moderately boosted. The boost lasts throughout the entire bass region, adding warmness to the overall sound.
Consequently, the elevation in the upper bass adds a little bit of boominess, but it isn’t as terrible as it sounds. Even on speedy tracks like “The Stage” by Avenged Sevenfold, the bass kicks are still nicely focused and controlled.
Midrange: Slightly recessed yet balanced for the most part
The midrange doesn’t deviate that much from what I consider natural. The tuning is similar to the Apple AirPods Max, albeit not as detailed and textured in the vocals.
The tuning is pretty similar to the Apple AirPods Max, but with a major difference in the treble.
Treblab Z7 Pro produce gritter electric guitars and have a warmer tone due to boosted bass.
Vocals sound reasonably natural but lack some air and lower treble to truly make them lifelike.
Moreover, instruments are produced in all their fullness, especially string ones. But again, they aren’t very detailed.
One example I found was in “I Will Remember” by Toto. Right at the beginning, the second set of drums is playing on the far-left side. Pricier headphones can portray them out quite easily, but they sound very faith on the Z7 Pro.
Treble: Smooth, with quick roll-off
Higher frequencies on Treblab Z7 Pro are extremely polite. Apart from the small peak at around 8.5kHz, the rest stays even with the midrange.
There is just enough quantity to keep you engaged. Cymbals produce a lovely shimmer, although they lack the crispness and texture of more premium headphones.
Still, this treble is perfect if you’re into laid-back listening sessions.
On the other hand, the extension is poor. Consequently, the sound lacks air, so it might feel a bit congested when listening to specific music genres, like rock or metal.
The Z7 Pro have a great sound, but it’s nowhere near audiophile-like.
Moving to the soundstage, it’s pretty good for closed-back cans. Though, since the imaging isn’t that great, you don’t feel as immersed in sounds coming outside your head.
Overall, I like the tuning of the Treblab Z7 Pro. With some tweaks here and there, these could’ve been excellent entry-level wireless headphones for audiophiles.
The biggest turnoff is the mediocre detail retrieval. The sound will do just fine for a casual listener, but you’ll instantly notice the difference if you’ve ever listened to something higher-end.
Treblab Z7 Pro aren’t the loudest headphones out there
Since some of you care about headphones’ loudness, it’s worth mentioning that these don’t play that loud. Compared to other wireless headphones, I had to push the Z7 Pro over 60% to reach a reasonable loudness.
That being said, at maximum volume, you can still damage your hearing when listening for a prolonged time. It’s good to practice safe listening volume when listening to headphones.
Comfort & Fit
4.5 Almost Perfect
Thick memory foam earpads and lightweight body ensure long-lasting comfort, while a fairly tight clamping force glue the headphones to your head.
Treblab really made sure you can wear the Z7 Pro all day long without complaining too much about comfort.
Earpads are thick and squishy, providing good comfort.
Oval-shaped ear cups are about as big as the ones on the Sony WH-1000XM4. Meaning they can take in most small and medium-sized ears without squishing them.
My ears barely fit, so I can’t complain. However, those with bigger ones might experience some pain after a long listening session.
The earpads use soft faux leather that feels gentle on your skin. The only downside is that it doesn’t breathe, so you’ll start sweating in no time.

The pads are filled with memory foam, while the headband uses regular foam. The latter is still decently thick and provides good support on top of your head.
Moving to stability, these over-ear headphones have a pretty tight clamping force. Thankfully, it doesn’t ruin the overall comfort. Instead, it ensures that Treblab Z7 Pro stay on, even when shaking your head.
You might as well use them for working out due to good stability. Sure, you’ll quickly start sweating, but since headphones sport an IPX4 rating, that shouldn’t be a problem.
Durability
4.0 Great
Primarily plastic construction with an aluminum reinforced headband feels sturdy and good quality. The hard-shell carrying case and an IPX4 rating add extra protection. But there’s something wrong with our unit. More on that later.
An aluminum headband without height markings.
Most headphones use plastic as their main build material. But it’s the quality of the plastic that matters. And in the case of Treblab Z7 Pro, the quality is quite solid.
A faux leather patch on the ear cups indicates the touch control’s position. The leather adds a bit of that premium factor, but it’s hardly noticeable due to a weird space-grey color.
Each ear cup has a pleather patch, indicating the touch-sensitive area.
Since headphones stay on your head relatively well, you can take them to the gym or for an outside run. So it’s nice to know they can handle sweat, thanks to an IPX4 rating.
The hard-shell carrying case protects against drops and prevents headphones from getting squished inside the luggage. There’s a soft mesh inside to store the cables.
Parts are put together tightly so they don’t rattle when you wear or shake the headphones.
At least in most cases. There’s one problem with our review unit.
Quality control issues?
I’ve noticed a small piece bouncing inside the left earcup. After a close examination, I saw that one of the yolks connecting the headband to the earcup isn’t flush with the earcup like the other three.
Slightly scuffed yolk (on the left side) should be flush with the ear cups, but it isn’t (on the right side).
This leads me to believe that maybe a screw got loose. Or something broke from the inside. Minor scratches are visible on the yolk, suggesting it got hit during production.
Nevertheless, I can only hear that piece when shaking the headphones and not during regular use. I only hope it doesn’t damage the dynamic driver.
Another minor complaint I have are the glued earpads. There’s no way you can replace the pads without tearing them.
That means you have to replace the whole unit if the earpads crack or become too stiff.
Glued earpads are impossible to remove, which isn’t great for repairability. Holes under earpads ensure breathability.
Battery
4.5 Almost Perfect
Battery test results: Treblab stuck a generous 39 hours and 34 minutes of battery life inside the Z7 Pro and equipped it with fast charging. It can recharge the headphones in just 2.5 hours.
Treblab Z7 Pro Battery Comparison
Dealing with batteries is always a hassle. Thankfully, most wireless headphones nowadays boast an excellent battery life, much like Treblab Z7 Pro.
With 39 hours and 34 minutes on a single charge (with ANC on), you can squeeze an entire week of use. And even when you hear a “low battery” prompt, fast-charging support will fill you right up.
It takes only 20 minutes to add another five hours of playtime.
Otherwise, headphones charge from 0-100% in 2.5 hours. They use a USB-C port for charging.
Features
4.0 Great
You get a good selection of premium and well-performing features like ANC, transparency mode, and touch gestures. However, there’s no app for customization and EQ settings.
Treblab Z7 Pro headphones offer most of what you expect from “pro” headphones. Active noise cancelling works really well for the price, while the ambient sound mode only moderately boosts the ambient noise.
Furthermore, a hidden proximity sensor automatically pauses playback when you put the headphones off your head. You can still trigger it by placing a finger inside the earcup, so I usually turn off this feature.
Regarding controls, there’s a mix of both touch and physical ones. The physical controls are:
Power on/off
ANC and transparency on/off
Initiate Bluetooth pairing
Physical buttons on the back of the right ear cup.
On the other hand, the responsive touch controls provide:
Double tap for playback commands
Swiping back and forward for skipping tracks
Swiping up and down to change volume
Tap and hold for 3 seconds to call a voice assistant
Placing your entire hand over the right earcup activates the transparency mode.
Unfortunately, headphones lack a mobile app. Even Anker Soundcore Life Q30, which cost $80, have a full-fledged app with complete customization, whereas Treblab Z7 Pro don’t.
While headphones by themselves work great, it would be nice to have the option to change the sound, relocate a touch gesture, or turn off the auto play/pause feature.
Microphone Quality
The voice quality from the main microphone in a quiet room is more than suitable for videoconferencing, online classes, and making quick phone calls.
Treblab Z7 Pro Microphone Test
The mic avoids overly aggressive filtering, resulting in fuller, more understandable vocals, albeit with more background sound.
Using the headphones in a noisier place noticeably affects the call quality, making your voice muffled. However, the end result is still doable for quick voice calls.
Noise Isolation
3.0 Good
Passive noise isolation is average at best. It can reduce outside noises by half, but you’ll have to activate ANC to fully enjoy your music in peace.
Despite having thick and dense earpads, Treblab Z7 Pro’s passive isolation isn’t all that impressive. It’s on par with Sony WH-CH710N, providing average results.
Air vents on top of the ear cups.
It seems the earcup’s plastic isn’t very thick, or it simply doesn’t have good sound-blocking characteristics.
During real-life testing, headphones manage to reduce background noises by half. That might sound a lot, but it isn’t. You can still hear things around reasonably well.
Furthermore, Treblab Z7 Pro also suffer from sound leakage. So you might want to reconsider how loudly you want to blast your music on a daily commute.
Noise Cancelling
3.5 Almost Great
Active noise cancellation works quite well for the price, eliminating almost all low frequencies and some of the higher ones. The highest tones are still audible, which is expected for the price.

Treblab Z7 Pro Sound Quality Test – HeadphonesAddict
Treblab Z7 Pro do a surprisingly good job blocking background noise. They do it better than Sony WH-CH710N, while they’re neck and neck with Anker Soundcore Life Q35.
Like most affordable ANC headphones, the Z7 Pro also do the best with lower frequencies. It reduces around 95% of the low-end hum, as you can still hear it faintly in the background.
That’s still good enough for commuters who want to primarily block engine noises.
Active noise cancelling also blocks some of the midrange and treble.
Nevertheless, Treblab Z7 Pro will help you make the noisiest environments less distracting, letting you enjoy your music without blasting it too loud.
What about transparency mode?
Awareness mode isn’t that impressive. It only moderately boosts the ambient sounds, so you have to take the headphones off when speaking to someone.
When speaking, you can still hear yourself as if your ears are covered, aka muffled. Higher-end headphones do much better in that regard.
Bluetooth
4.0 Great
While Bluetooth performance is average, headphones offer other interesting candies, like an aptX and aptX HD codec, multipoint support, and no visible audio lag during videos.
Treblab Z7 Pro use Bluetooth 5.0 for audio transmission purposes, and it’s quite reliable for the most part. I haven’t experienced any random dropouts or stutters when using headphones near the source.
Treblab headphones also come with advanced features like aptX HD.
The Bluetooth range is average, reaching around 40-45 feet indoors. After which, the audio completely stops playing.
How easy is it to pair?
Headphones initiate pairing soon after you turn them on for the first time. Otherwise, you long-press the Bluetooth button under the right earcup until you see a small LED blinking red and blue.
Since Treblab Z7 Pro support multipoint, you use the same steps when trying to pair them to multiple devices simultaneously.
What Bluetooth Codecs Do They Use?
Treblab Z7 Pro use standard SBC, Apple-friendly AAC, and Android-focused aptX and aptX HD. The latter ensures higher audio bandwidth for high-res audio transmission.
However, you must use a smart device that supports the aptX HD Bluetooth codec, and if you have an older phone, you might have to upgrade. See the list of aptX HD-supported smartphones and media players.
Nonetheless, the Z7 Pro are future-proof and support High-Res sound over Bluetooth.
Is There an Audio Lag?
There’s no visible lag whatsoever, making them perfect for watching movies and YouTube videos.
Should You Get Treblab Z7 Pro?
3.5 Almost Great
While there is room for improvements, the Treblab Z7 Pro makes perfect sense for someone looking for headphones with a well-balanced sound and good ANC.
On top of that, they’re comfortable headphones, well-built (despite our unit having some minor issues), and sport an IPX4 sweatproof rating.
The battery life is fantastic, the microphone quality reliable, and you even get support for the aptX HD and multipoint.
If there were a companion app with custom controls and an audio equalizer, I would rate the value even higher. Nevertheless, for $120, these are a good deal.
The Ankers have a more hyped sound with both bass and treble boost. Thankfully, you can correct the sound to an extent within the app.
The latter offers a ton of customization, which Treblab headphones lack.
Active noise cancelling is about on par with the Z7 Pro. The battery life of 40 hours is also similarly impressive. And while Treblabs offer aptX HD, the Q35 supports LDAC.
