TOZO T10 Review

I didn't expect to be impressed at this price, and I wasn't. These earbuds are fine. The thing is, the JLab Go Air Pop+ earbuds cost even less and earn higher scores, with slightly better sound quality. The only place these earbuds outperform the Air Pop+ buds is in voice isolation during phone calls. 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.

Performance Comparison

Sound Quality

I'm underwhelmed with the sound quality of these earbuds. 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 you to succeed.

The mix does not sound natural, as it is dominated by bass frequencies. 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 centerstage 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. These earbuds can also get really loud, but they lose clarity at higher volumes and detail at lower levels.

To back up our impressions, we use a Brüel & Kjaer Type 5128 ear and head simulator (aka Darwin) and SoundCheck software to map out the frequency response of each earbud. Then we graph it beside the GearLab House Curve benchmark to see how they compare. 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 to our testers.

User Experience

These buds leave a lot to be desired, between an uncomfortably fitting tip and a frustratingly cluttered app, they're difficult to recommend. Unless you find an incredibly good deal on them, I suggest skipping them for more user-friendly options, like the JLab Go Air Pop+.

Comfort

Though these earbuds feel soft and comfortable off the bat. I inevitably breathe a sigh of relief when removing them after nearly an hour. The long tips sit deeper in your ear canal than most options, creating more pressure on sensitive skin. They aren't really good or bad on the comfort scale, just okay.

They don't feel bulky, despite their looks, and don't make much noticeable contact with the outer ear. Every time I catch my reflection, though, I can't help but think they look terrible. Don't expect a sleek aesthetic.

Stability

Thanks to that elongated tip, these earbuds stay firmly in place. I can get them to wiggle, if I try really hard, but they are stable overall.

Adjustability and Tunability

You can download an app for these earbuds on Apple and Android devices. It's listed as the TOZO-technology surrounds you app on iOS and TOZO-tech around you on Android, names that hint at the clunky, cluttered feel of the app itself. 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 also customize the touch controls, which fields playback, volume, and calls. That said, I find the default settings intuitive already. If you dig deeper, you'll find odd features like shop and social media interfaces and an AI area. Yet, AI features don't seem to be supported with these earbuds. I would appreciate a more streamlined app experience.

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

Noise Cancellation

Earbuds can dull distracting sounds from the world around you in two ways. First, they physically block sound waves from entering your ear, which is known as passive noise isolation. All earbuds offer this service to a greater or lesser extent.

The second method is through active noise cancellation (ANC) technology. While it's common among the more expensive earbuds tested, the TOZO T10 earbuds do not offer ANC, so it doesn't score particularly well in this metric.

That said, its passive noise isolation is shockingly effective, probably thanks to those extra-long eartips. You can still hear what's going on around you, but it's muted. I can barely hear my typing at the office, and the treadmill is blessedly subdued at the gym. You can hear for yourself in the video below.

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.

Battery Life

While the manufacturer claims that these earbuds should last around 10 hours on a full charge, I only got them to run for 7 hours and 44 minutes in our tests. That's usually enough to get through a full day, though. It takes about an hour and a half to charge them back up fully. Since the case can hold enough power for 4.5 recharges, you can do that on the go.

Call Quality

These earbuds offer a more reliable performance when it comes to isolating your voice during calls. In our lab test, we played recordings through Darwin's mouth simulator to see how well we could hear them on the other end in various scenarios. We recorded both a man's and a woman's voice to check the results in both frequency ranges.

The recordings came through decently in a quiet room, with just 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 like the Samsung Galaxy Buds3 Pro. They struggle a touch more in a moderately paced office environment, since surrounding sounds leak into the recordings. You can still easily understand both voices, though.

With a recording from 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 an okay option. There are many better options, though, and some of them cost even less. I don't think the uncomfortable fit and finicky app are worth it.

What Other Earbuds Should You Consider?

If you're looking for a pair of earbuds around this price point, I'd steer you directly to the fabulously functional JLab Go Air Pop+ earbuds. They don't have the most sophisticated sound, but they're more consistent and enjoyable than the T10buds. They're also much more pleasant to use. If you're willing to spend a bit more for higher quality audio and improvements in every category except for call quality, the EarFun Air Pro 4 offers impressive value.
