TOZO T6 Truly Wireless Headphones Review

The TOZO T6 are fairly standard looking truly wireless earbuds. They look almost identical to the TOZO T10 Truly Wireless, but have touch-sensitive controls instead of physical, clicky buttons. The earbuds are covered in a matte plastic, except for the touch-sensitive area which is glossy. While we bought the black model, they're also available in white or rose gold.

The TOZO T6 are decently comfortable. They come with six different sizes of tips to help you get a good, comfortable fit, which is great. While they fit similarly to the TOZO T10 Truly Wireless, they're slightly thinner and smaller in certain areas which makes them more comfortable in the ear. They also have touch-sensitive buttons, so you won't push them painfully into your ear when you press buttons, like with the T10.

The controls of the TOZO T6 are alright overall. They have touch-sensitive controls that are quite easy to use and follow a control scheme that makes logical sense. You can tap once on either earbud to play/pause, tap twice on your left or right earbud to skip tracks back or forwards, respectively, and hold the left or right earbuds to adjust volume down or up. You can also pull up your phone's voice assistant by pressing three times on either earbud. Their touch buttons don't offer as good feedback as clicky physical buttons, but you do get voice prompts or beeps to let you know when it's registered your commands, which is nice.

Like most truly wireless earbuds, the TOZO T6 are very small and should be able to easily be tossed into most pockets.

The case for the TOZO T6 is good. It feels slightly more premium than the case of the TOZO T10 Truly Wireless and is quite a bit smaller, closely resembling the case of the Apple AirPods. In addition to plugging in a USB cable to charge, you can also charge the case by simply dropping it onto any Qi-enabled wireless charging pad, which is a nice addition. There are four lights on the case itself to let you know how much battery you have left, and the case is rated IPX8 for waterproofing, though this isn't something we test for.

The build quality of these headphones feels good overall. They're made out of dense plastic and feel solid and able to withstand a few accidental drops or bumps. Both the earbuds and the case are rated IPX8 for waterproofing, though this isn't something we currently test for.

The TOZO T6 True Wireless Earbuds feel quite stable in the ear. Even without having stability fins, they should stay in place for basic workouts or light runs.

The TOZO T6 have a decently well-balanced and excited-sounding sound profile. They will add a bit of extra pop and kick to most genres, though their recessed mid-treble range means they may not be the best choice for fans of jazz or classical music.

The frequency response consistency of these headphones is excellent. Once you achieve a proper fit with the included tips, you should get the same audio delivery every time you use the headphones.

The TOZO T6's bass accuracy is quite decent. The entire range is almost entirely flat, and while it's slightly overemphasized, it isn't by too much, so bass shouldn't sound overpowering or boomy.

The TOZO T6 have excellent mid-range accuracy. The entire curve is almost entirely neutral, except for mid-mid which is slightly recessed. While this will push instruments and vocals slightly back in the mix, it likely won't be too noticeable to most people.

The treble accuracy of the TOZO T6 is mediocre. Low treble, responsible for the presence and detail of instruments and some vocals is slightly over-emphasized, though it shouldn't sound too harsh or painful. The dip in high low-treble and mid-treble will result in instruments like cymbals sound dull and lispy, which may bother fans of genres like jazz, classical, or pop. While the sharp peak immediately following the dip may cause some sounds to be sharp and piercing.

The peaks and dips performance of the TOZO T6 is decent. Their most noticeable dip is the large one in mid-treble. This will cause instruments like cymbals to be lacking in brightness and presence. While this may not be completely apparent to everyone or with all types of music, it'll likely make instruments in some genres like jazz or pop sound slightly dull.

The imaging performance of these headphones is excellent. Their weighted group delay graph shows that the entire response is well below the audibility threshold, ensuring tight bass and transparent treble. The left and right drivers of our unit were also well-matched in frequency, amplitude, and phase response, which is important for the accurate placement and localization of objects (voices, instruments, video game effects) in the stereo image. However, these results are only valid for our unit and yours may perform differently.

Like most in-ears, the soundstage performance of the TOZO T6 is terrible. This is because creating an out-of-head and speaker-like soundstage is largely dependent on activating the resonances of the pinna (outer ear) but in-ears are designed in a way that bypasses the pinna completely. They're also closed-back earbuds, so their soundstage won't feel as open as that of open-back earbuds like the Apple AirPods 2 Truly Wireless 2019, Google Pixel Buds Wireless, or the Bose SoundSport Free Truly Wireless.

These Bluetooth in-ears don't have any virtual soundstage features.

The weighted harmonic distortion performance of the TOZO T6 is good. They tend to distort a bit more in the higher frequencies, which can be a bit more noticeable, but it's still within good limits, and most people likely won't have any issues even at louder volumes.

These are the settings used while testing these headphones; therefore, the results are only valid for these test settings.

Due to the lack of a companion app, we were unable to determine the firmware version. If you own these headphones and know where to find it, let us know in the discussion section below.

The TOZO T6 have great noise isolation. While they don't have an active noise cancellation (ANC) feature like some more expensive options, they passively block out background noises quite well, providing you achieve a proper fit with the included tips. They do an excellent job blocking out background chatter and the high-pitched noise of an AC unit. While they don't do the best job overall in the bass range, they block a fair amount in low-bass, where the low rumbles of bus or plane engines sit.

The TOZO T6 leak almost no audio. You should be able to play music quite loud without bothering people sitting next to you, making them a decent option to keep you concentrated in the office.

These Bluetooth in-ear headphones have an integrated microphone.

The microphone recording quality of these headphones is decent. Your voice should be decently clear and easy to understand, but unfortunately it'll be thin and lacking in detail, like with most Bluetooth in-ears.

The noise handling of the microphone is disappointing. While the person you're speaking to will be able to hear you in quiet situations, your voice will get lost in even moderately noisy environments.

The battery performance of the TOZO T6 is sub-par overall, though it's fairly standard for truly wireless headphones. Their 5.3-hour battery life is slightly above average for a pair of truly wireless earbuds in 2020, and their case gives an additional four charges. While they won't last an entire work day off a single charge, you can top them up in their case during your lunch break.

These headphones don't have a dedicated companion app, so you can't EQ their sound or alter their control scheme. To update their firmware, TOZO offers a downloadable APK for Android devices, but this only updates the headphones and serves no other purpose.

Unfortunately, the TOZO T6 don't support multi-device or NFC pairing, so you can only connect them via Bluetooth to one device at a time.

These truly wireless earbuds are Bluetooth-only.

As with all truly wireless in-ears that we've tested so far, these headphones can't be used wired. They come with a short micro-USB cable to charge the case.

These headphones aren't compatible with the PS4. While they'll connect to a Bluetooth-enabled PC, they aren't recommended for gaming due to their high latency.

These truly wireless earbuds only support Bluetooth, so they aren't compatible with the Xbox One.

The charging case for these headphones supports wireless Qi charging and will hold an additional four charges. Like most truly wireless headphones, there are no inputs on the case.
