The Bottom Line:​

The TREBLAB Z2 Wireless Headphones offer premium features at a budget price! With excellent battery life, an IPX4 rating (totally sweatproof!), as well as Bluetooth 5.0 connectivity, the TREBLAB Z2 is bound to be your next favorite pair of workout headphones!

TREBLAB is a fairly new brand on the market but it’s fast becoming a household name – and for good reason! Founded in 2015, TREBLAB has been working hard to be known as a brand that produces high-quality wireless audio products that are accessible to everyone. Today we’re taking a closer look at the TREBLAB Z2 Wireless Headphones. Packed with premium features like Bluetooth 5.0, active noise cancelation (ANC), and an IPX4 waterproof rating, the Z2 offers many of the things you’d expect to see in high-end headphones. How do they fare? Let’s take a look!

Unboxing & First Thoughts

The packaging of a product can generally give you a fairly good indication of the quality you can expect of the product itself. It’s the first impression of the item and everyone enjoys a good unboxing experience! For a pair of headphones that costs less than 100 dollars, TREBLAB has really gone the extra mile here. The box is sturdy, with a magnetic-opening flap. Inside, you’ll find the headphones with its hardshell travel case, USB charging cable, 3.5mm anti-tangle/flat AUX cable with an inline mic, and a small carabiner. On the left-hand side of the box is a pouch. Inside the pouch, you’ll find the user manual, a product registration card, and a free TREBLAB sticker.

Headphone Design & Comfort

Featuring an almost all-black design, the TREBLAB Z2 offers a sleek, modern, and stylish aesthetic. The finish of the headphones is matte, with the outer ear cups featuring the TREBLAB logo over a gloss metal. When handling the Z2, they look and feel like a premium pair of headphones. The metal adjustment slider allows for up to 7 size adjustments and holds just enough tension to ensure it stays in place.

The TREBLAB Z2 Headphones offer an over-ear fit, and while the inner ear cup is on the slightly smaller side, the padding is soft and doesn’t cause any ear fatigue. Equally, the padding along the top of the headband is ample and provides excellent comfort. The ear cups also have a 100° swivel layout, which not only ensures a more comfortable fit but also extended longevity when compared to other headphones in this price range. It also makes transporting them easier, as they sit flush inside the carry case.

Workout Headphones & Office Use

Designed specifically as workout headphones, the TREBLAB Z2 will make the perfect gym accessory. They’re low-key but stylish and offer the perfect balance between clamping force and comfort. This means that they stay in place during your workout but they also don’t cause any discomfort over long periods of wear. The earcups and headband are lined with PU leather and while this does tend to make your ears hotter than fabric would, it is far more hygienic and easier to keep clean.

The TREBLAB Z2 headphones can also be worn in the office for extended working hours without causing ear fatigue and discomfort. While some sound leakage is present at higher volumes, almost all headphones (as opposed to earphones) will leak sound at higher volumes. When listening to music at a standard volume, we did not experience any significant sound leakage.

Headphone Controls

TREBLAB has kept the controls simple and intuitive. On the left earcup, you’ll find the ANC (Active Noise Cancelation) ON/OFF switch, along with a small red LED indicator that illuminates when the ANC is turned on.

The right earcup houses the power on/off button which is also the play/pause button. This button also features a raised notch so that you’re able to find it easily while still wearing the headphones. To the left of this button you’ll find the Volume + / Next track button, and to the right is the Volume – and Previous track button. A single press adjusts the volume, while a press and hold will adjust the track selection. The integrated mic, AUX line-in, and USB charging port can also be found on the right earcup, along with a small LED indicator for power and Bluetooth connectivity.

To answer a call, simply short-press the power button, and then short-press again to end it. Pressing and holding the power button for 2 seconds will reject the call while pressing the power button twice will activate your voice assistant.

TREBLAB also includes a 4-ft long, anti-tangle/ flat AUX cable with an inline mic and button for a wired connection. It’s important to note that, when using the AUX cable, the pause, track selection, and volume adjustment controls on the headphone will not work. Instead, you will need to make these adjustments on your smart device or via the in-line button on the cable.

Sound Quality

The TREBLAB Z2 Wireless Headphones feature 40mm, neodymium-backed drivers. These headphones are ideal for a wide variety of music genres. They have a well-balanced sound profile and are great for everything from hip-hop and rock to classical music. The midrange performance is excellent! Vocals and instruments are present and clean, without being harsh, muddy, or distant. 

Treble performance is decent, while the bass range is slightly under-emphasized and that can be a turnoff for fans of bass-heavy genres. Often we see brands apply too much bass boost to their headphones, resulting in a distorted and muddy sound. This is certainly not the case with the TREBLAB Z3 Headphones. Overall, they provide an enjoyable listening experience.

Technical Specs & Features

Noise Cancellation

Featuring Active Noise Cancellation, the TREBLAB Z2 Headphones do a good job at blocking out background noise. While some sounds are still present, with the ANC turned on but music off, these disappear as soon as you begin playing your music. Tested in a busy gym, the Z2  Headphones blocked out the sounds of the overhead music being played inside the gym. If you’re intending to use these headphones outside of the gym as well, the noise cancellation also works well drowning out the sound of an AC or fan, making them great for office use too.

Battery Life & Charging

The TREBLAB Z2 offers a battery life of up to 35 hours. As with all wireless headphones, it’s important to note that listening to music at higher volumes as well as using the ANC feature will drain the battery faster. Listening at 100% volume without the ANC turned on, you can expect around 20 hours of playtime while turning the ANC on will reduce this to 12 hours. Generally speaking, if you listen to music at medium volume with the ANC turned on, you can expect around 22 hours of battery life. The Z2 also features Quick Charge functionality, which ensures your headphones will be fully charged within just 3 to 4 hours.

Wireless Connectivity

The TREBLAB Z2 Headphones feature Bluetooth Version 5.0 as well as a Qualcomm QCC chipset with aptX. Previously, Bluetooth headphones had a bad rep in terms of sound quality. Flash forward to today and Qualcomm’s aptX technology helps to deliver high-quality Bluetooth audio.

AUX Connection

If your battery happens to run flat, or you just prefer a wired connection, you can use the included 4-ft long, anti-tangle/ flat AUX cable. The cable includes an inline mic and an inline button that allows you to activate your voice assistant with a 1-second press. You can also short-press the button to play/pause your music, press twice for the next track, or triple press for the previous track.

IPX4 Water Resistance

As workout headphones, there’s naturally going to be sweat involved. Thankfully, the TREBLAB Z2 features an IPX4 rating. This means that they are actually water-resistant rather than waterproof (you can’t submerge them in water). However, they are still protected from splashes of water and are fully sweatproof.

Voice Assistant & Phone Calls

As previously mentioned, the TREBLAB Z2 headphones are voice assistant compatible and can be used with either Siri or Google Voice Assistant. With an integrated mic, as well as an inline mic on the AUX cable, you are able to use your voice assistant and call function wirelessly or via a wired connection.

How to Pair your TREBLAB Z2 Headphones

Step 1: Ensure that your headphones are fully charged and that the AUX cable is not plugged in.

Step 2: Press and hold the power button for 5 seconds. You will hear the voice prompt say “Power ON”, followed by “Pairing”.

Step 3: Scan for Bluetooth devices on your smart device and select the TREBLAB Z2 headphones.

Step 4: If a password is required, enter “0000”.

Step 5: Upon successful pairing, you will hear the voice prompt say “Connected”.

If you experience any issues with pairing, ensure that the headphones are within 30ft of your device and that the AUX cable is not plugged in. The Z2 headphones can only be paired with 2 devices at a time. To remove previously paired devices, reset the memory limit on the headphones. 

To do this, turn the headphones ON, then press and hold the Volume + and Volume – buttons down at the same time for 5 seconds. The headphones will turn off automatically, signaling that the memory has been cleared and you can then proceed to pair your new device. If you still experience an issue with pairing, try turning your smart device off/on again. 


The TREBLAB Z2 Wireless Headphones are perfect for the gym as well as the office. Despite their budget price-point, that’s the only thing “cheap” about these headphones. From build quality to features, and even the included accessories, TREBLAB has truly exceeded expectations for headphones priced below 100 dollars. Offering Active Noise Cancelation, Bluetooth 5.0, an IPX4 rating, and even the ability to have a wired connection, the TREBLAB Z2 packs a variety of premium features that compete with high-end brands. If you’re looking for a new set of cans, look no further than the TREBLAB Z2 – you’ll certainly be impressed!
