TOZO T10 Review

The TOZO T10 is fine. Thanks to a strong emphasis on the bass frequencies, they sound better with hip hop or synth pop than they do with mid-tone focused country and folk songs.

Sound Quality

We were underwhelmed with the sound quality of TOZO. The cramped soundstage makes it a challenge to separate or place individual instruments. There isn't enough clarity to pick out many details, leaving your favorite songs devoid of their normal luster. If you're a gamer, these earbuds won't give you enough auditory information (think footsteps sneaking up behind you) for success.

The mix does not sound natural, as bass frequencies dominate it. If you're a bass lover, you may find it fun, but it lacks balance. The mid-range can often hold its own, and voices sound reasonably realistic. But, at times, they're competing for space. The treble tones rise above the fray for the most part. They can sound thin, but they're controlled enough to avoid distortion or piercing highs.

Take “Sad & Blue” by Charley Crockett. His vocals are center stage as the funky organ and warm trumpet merge with the funky percussion. This song is a rhythmic bop, and the emphasized lows add energy to the mix.

On Joey Bada$$'s “ROCKABYE BABY,” the deep synths and percussion bring emotional weight, especially when the beat drops in at 2:04. Lana Del Rey's “A&W” also works well — these buds highlight the haunting piano and guitar while keeping the layered vocals front and centered. The bass notes cut through the mix to add drama without stealing the limelight.

At other times, the bassline muddies down to a mess. These earbuds certainly have a dramatic take—it's just not a realistic one. They can also get really loud, but they lose clarity at higher volumes and detail at lower levels.

We use a Brüel & Kjaer Type 5128 ear and head simulator and SoundCheck software to map out the frequency response. We graph it beside the GearLab House Curve benchmark for comparison. The blue, TOZO, frequency curve is elevated in the low, bass frequencies and spikes above our preferred curve in portions of the mid and treble ranges. That could be why these earbuds sound somewhat unnatural.

Comfort and Fit

These earbuds feel soft and comfortable off the bat, but our ears breathe a sigh of relief when we remove them after an hour. The long tips sit deeper in the ear canal than most options, creating more pressure. They aren't good or bad, they are just okay.

Despite their design, they don't feel bulky or make noticeable contact with the outer ear. However, they aren't aesthetic, and we think they look terrible.

Stability

Thanks to that elongated tip, these earbuds stay firmly in place. We can get them to wiggle, if we try really hard, but they still stick in place.

Noise Cancellation

Earbuds can dull distracting sounds from the world around you by physically blocking sound waves from entering your ear (passive noise isolation) and active noise cancellation (ANC) technology. All earbuds offer some level of passive noise isolation.

The TOZO T10 earbuds do not offer ANC, so it doesn't score particularly well in this metric. However, its passive noise isolation is shockingly effective. You can still hear what's going on around you, but it's muted. We could barely hear office typing, and the treadmill hum is dampened.

While it's nice that these buds act like earplugs, they're not comfortable enough for the trade-off to be worth it for many of our testers.

To add data to our impressions, our test team used Darwin (our Brüel & Kjaer 5128 head-and-ear simulator) and SoundCheck software to measure how much the earbuds quieted the sounds of a noisy cafe. The results reveal that, even without ANC, these earbuds can block between 10 and 40 decibels of background sound.

Ease of Use

These buds leave a lot to be desired, with a frustratingly cluttered app.

App Features

TOZO offers an app for Apple and Android devices. Identified as the TOZO-technology surrounds you app on iOS and TOZO-tech around you on Android, the names hint at the clunky, cluttered app you get. It's so packed with features that it's hard to navigate, and many of them feel gimmicky. Thankfully, the adjustable EQ presets are easy to access from the home screen and are by far the most useful tool.

You can customize the touch controls, which include playback, volume, and calls, but the default settings are intuitive. If you dig deeper, you'll find odd features like shop, social media interfaces, and an AI area (unsupported with these buds).

Pairing the earbuds can also be frustrating since they won't connect to a new device until you manually unpair them from the previous one. Therefore, they're best for people who use only one phone or computer.

Battery Life

While the manufacturer claims the TOZO should last 10 hours on a full charge, we saw 7 hours and 44 minutes play time during testing.

It takes about an hour and a half to charge them fully, and the case holds enough power for 4.5 recharges on the go.

Call Quality

The TOZO offers a reliable performance when it comes to isolating voices during calls. We played recordings through the mouth of our head simulator to see how well we could hear them in various scenarios. We recorded both male and female voices to check the results across frequency ranges.

The voices were transmitted decently in a quiet room, with a hint of graininess. They were easy to understand with plenty of power and volume, though they aren't as natural and life-like as higher-priced options. They struggled a little in a moderately paced office, since surrounding sounds leaked through, but we could still easily understand both voices.

With a subway platform in the background, more of the shrill sounds bleed into the recording. It's loud enough to cut off a syllable here or there, but the earbuds keep the voices front and center, making it possible to follow the conversation.

Should You Buy the TOZO T10?

Should you buy these earbuds? Probably not. If you find a great deal, and you really like bass or need them for phone calls, they could be okay. There are many better options, and some of them cost even less. I don't think the uncomfortable fit and finicky app are worth it.
