The TOZO T6 are fairly non-descript headphones. While they look almost identical to the TOZO T10 Truly Wireless, they 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' color variants.
The TOZO T6 True Wireless Earbuds are decently comfortable. They come with six different sizes of tips to help you get a good, comfortable fit. 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. If you're looking for something more comfortable, but still affordable, check out the Mpow M30 Truly Wireless or ENACFIRE E60 instead.
The controls of the TOZO T6 True Wireless Earbuds are alright overall. They have touch-sensitive controls that are quite easy to use. 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.
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 (2nd generation) Truly Wireless. You can either charge them with their included Micro-USB to USB-A cable or 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 water resistance, though this isn't something we test for.
These headphones have a good build quality. They're made out of dense plastic and feel solid. They should be able to withstand a few accidental drops or bumps without taking too much damage. Both the earbuds and the case are also rated IPX8 for water resistance, though this isn't something we currently test for.
The TOZO T6 have a slightly bass-heavy sound profile. They can reproduce a touch of extra thump, rumble, and boom, while vocals and lead instruments are detailed and clear. However, sibilants like cymbals sound dull. Unfortunately, they lack sound enhancement features like an EQ to tweak their sound to better suit your tastes. If you want budget earbuds with integrated EQ presets, check out the Skullcandy Smokin' Buds/Buds XT True Wireless.
The frequency response consistency of these headphones is outstanding. 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 decent. The entire range is overemphasized, although it's almost entirely flat in response. This results in a thumpy, boomy sound that should please fans of EDM and hip-hop. However, some users may find it sounds too boomy.
The TOZO T6 have excellent mid accuracy. Overall, the response is fairly neutral, though there's a dip in the mid-mids, which pushes instruments and vocals slightly back in the mix. That said, vocals and lead instruments still sound clear, and accurate.
The treble accuracy of the TOZO T6 is mediocre. The low-treble, which is responsible for the presence and detail of instruments and some vocals, is slightly over-emphasized, though it shouldn't sound too harsh or painful. There's a dip between the low to mid-treble, which makes the upper harmonics of vocals and lead instruments, as well as sibilants like cymbals, sound dull and lispy. There's also a peak in the mid-treble, which can make sibilants sharp and piercing.
The peaks and dips performance of the TOZO T6 is decent. There's a dip in the mid-mids, which pushes vocals and lead instruments to the back of the mix while a peak in the low-treble makes the upper harmonics of these sounds harsh. There's also a deep dip and peak in the mid-treble, which makes sibilants like S and T sounds alternatively dull and piercing.
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 are 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. Since they're in-ear headphones, they completely bypass the outer ear, which is an important factor in creating an out-of-head and speaker-like soundstage. As a result, the soundstage is perceived as coming from inside your head. Their closed-back design also means that their soundstage won't feel as open as that of open-back earbuds like the Apple AirPods (2nd generation) Truly Wireless or the Bose SoundSport Free Truly Wireless.
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. However, 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 more premium options, they passively block out background noises quite well, providing you achieve a proper fit with the included tips. They do an outstanding job of blocking out background chatter and the high-pitched noise of an AC unit. However, they really struggle to cut down the low rumbles of bus or plane engines. For headphones with a dedicated ANC feature, check out the TOZO NC9 Truly Wireless.
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 suitable option to keep you concentrated in the office.
The microphone recording quality of these headphones is decent. Your voice should be decently clear and easy to understand, but unfortunately, like most Bluetooth in-ears, it's thin and lacking in detail.
The noise handling of the microphone is disappointing. While the person you're speaking to should be able to hear you in quiet situations, your voice gets lost in even moderately noisy environments like a busy street.
The battery performance of the TOZO T6 is sub-par. They're advertised to have six hours of continuous playback time, but we measured slightly under this amount. Even though they don't have any power-saving features, their carrying case holds roughly four additional charges, which is handy in a pinch. However, battery life can vary according to usage, so your results may vary.
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 have okay Bluetooth connectivity. They don't support multi-device or NFC pairing, so you can only connect them via Bluetooth to one device at a time. Unfortunately, they have higher latency on PC, iOS, and Android than the similarly designed TOZO T12 Truly Wireless, so you may experience delays if you're streaming video. That said, some apps and devices compensate for latency differently, so your real-life experience may vary.
The charging case for the TOZO T6 supports wireless Qi charging and holds an additional four charges. Like most truly wireless headphones, there are no inputs on the case.
