TOZO T10 Truly Wireless  Headphones Review

The TOZO T10 are fairly straightforward looking small truly wireless earbuds. Their physical buttons have a flat surface and they don't stick out too far from the ear. They're covered in matte plastic, with a small ring of glossy black, and overall don't appear too cheap. While we purchased the black model, they're also available in white, gray, blue, or khaki.

These headphones are less comfortable than most truly wireless in-ears we've tested. While they come with four different sizes of tips to help find the best possible fit, the tips are quite stiff. The physical controls also require a lot of pressure to press and push the earbuds deep into your ear, which can be fairly painful. If you want something similar that have touch-sensitive controls and are much more comfortable, check out the TOZO T6 Truly Wireless. If you prefer something with an earbud design that doesn't enter the ear canal as deeply, consider the JBL TUNE 220TWS Truly Wireless.

The control scheme on the TOZO T10 is bad. The single button on both buds does the same action and the only music playback controls you get are to pause/play a track. The rest of the controls are related to phone calls and allow you to answer/hang up, reject a call, or redial. This is rather disappointing compared to most other truly wireless headphones which at least allow you to skip tracks. The double click to redial also makes it too easy to accidentally call someone. There's audio feedback when pairing, powering on/off, or redialing, though the voice tells you that it's redialing, even if there's no number to redial. The physical buttons of the controls are also quite stiff and require a lot of force to press, pushing the earbuds deep into your ear. Consider the TOZO T12 Truly Wireless if you're looking for a similar pair of truly wireless headphones that are easier to use.

Like most truly wireless earbuds, the TOZO T10 Bluetooth 5.0 Wireless Earbuds are very small and portable and can easily be tossed into your pockets.

The case of the TOZO T10 is good. While it doesn't feel quite as premium as some more expensive options, it doesn't feel too cheap and has good magnets to help keep the lid closed. It also features Qi-enabled wireless charging, which is very rare at this price point. The case is also rated IPX8 for waterproofing, though this isn't something we currently test for.

The overall build quality of the TOZO T10 is good. While they're made out of plastic, they feel quite dense and solid. Both the earbuds themselves and the case are rated IPX8 for waterproofing, though this isn't something we currently test for.

The TOZO T10 feel quite stable. While they would feel even more stable with stability fins, they still likely should stay in your ears well even during light runs or workouts.

The TOZO T10 have a very warm, bass-heavy sound profile. They pack a serious punch with deep, thumping bass that's suitable for genres like EDM or hip-hop. However, they'll sound a bit too muddy and cluttered for folk, jazz, or classical music.

The frequency response consistency is outstanding. If the user can achieve a proper fit and an air-tight seal using the assortment of tips that come with the headphones, then they should be able to get consistent bass and treble delivery every time they use the headphones.

The bass accuracy of the TOZO T10 is terrible. The entire range is very overemphasized, which will result in thumpy and boomy bass. While this isn't neutral or accurate, it will likely please fans of EDM or hip-hop who want a lot of extra kick in their music.

The mid-range accuracy of these headphones is good. The entire range is fairly well-balanced, though the mid-mid range is a bit recessed, which will push lead instruments back in the mix.

The treble accuracy of these headphones is decent. While the entire low-treble range follows our target curve quite well, there's an over-emphasis in mid-treble that will help keep vocals and lead instruments from getting too overpowered and drowned out by bass. Unfortunately, this may sound sharp and piercing to some.

The TOZO T10 have quite a few peaks and dips. The large hump starting at mid-bass and continuing until low-mids brings extra kick and punch, but will cause the overall sound profile to sound a bit muddy and cluttered. The dip during the mid-mid range will push lead instruments further back in the mix, while the large spike in mid-treble will help prevent vocals and some higher frequency leads from getting drowned out, though it may sound a bit sharp to some.

These headphones have great stereo imaging. 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 passive soundstage performance of these headphones is awful. 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 (2nd generation) Truly Wireless, 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 T10 Bluetooth 5.0 Wireless Earbuds 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 headphones' results are only valid for these test settings.

However, 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 noise isolation performance of these headphones is surprisingly impressive. 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 outstanding job isolating noises in both the mid and treble ranges, which will help with background chatter and the noise from AC units. Unfortunately, they may not be the best for blocking the low rumble from bus or plane engines, though they do better at this than most earbuds without ANC.

Like most closed-back in-ears, the TOZO T10 Bluetooth 5.0 Wireless Earbuds leak very little audio. Most of the leaked audio comes from the treble ranges, so it will sound quite thin. These are a good option for using at work without bothering those around you, as even at moderate volumes, the leakage should be masked by the ambient noises of your average office or home.

These Bluetooth in-ear headphones have an integrated microphone.

The microphone recording quality of these headphones is slightly better than most Bluetooth in-ears and surprisingly decent overall. Your voice should be clear and easy to understand, but unfortunately, will still likely sound fairly thin and lacking in detail.

Update 11/10/2021: These headphones have been updated to test bench 1.5. In this update, we made changes to the way we test noise handling. We now use a subjective evaluation of our audio clips. This new method has resulted in different results than what we had reported in our previous test bench. As a result, the scoring of this box has changed, and we have updated our results.

The noise handling of the microphone is passable. While the person you're speaking to should be able to hear you in quiet situations, your voice can be drowned out in even moderately noisy environments.

The battery performance of these headphones is disappointing. Their 3.5-hour battery life is on the shorter side for truly wireless headphones, and their case only gives an additional four charges, despite being fairly large. On the bright side, they deliver a longer battery life than the 3 hours that's advertised, and they only take an hour to fully charge.

These headphones don't have a dedicated companion app, so you can't EQ their sound or alter their control scheme.

Update 11/10/2021: These headphones were updated to Test Bench 1.5 and their latency values have changed. Our previous Test Bench 1.4 measurements reported 'PC Latency ' at 323 ms, 'iOS Latency' at 152 ms, and 'Android Latency' at 295 ms. However, our new test bench uses an average of three measurements instead of one, resulting in 322 ms of latency on PC, 74 ms on iOS, and 190 ms on Android. As a result, we have updated our text to better reflect test bench 1.5 measurements.

The TOZO T10 are truly wireless in-ears that support Bluetooth 5.0. Unfortunately, they don't support multi-device or NFC pairing, and their line of sight range is lower than many similar options. Their latency is also quite high on PC and Android, which is disappointing if you like to stream video. However, they have significantly lower latency on iOS devices. Some apps seem to compensate for latency, though, so your mileage may vary during personal use.

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 truly wireless earbuds only support Bluetooth, so they're not compatible with the Xbox One.

The charging case for these headphones should give you up to four additional charges, but like most truly wireless headphones, it doesn't have any inputs.
