TOZO T10 Review

Our TOZO T10 Experience

The TOZO case is elongated and more of a rectangle than a square. They have fun lights inside when you flip the lid, and clearly marked L and R indicators that match similar marks on the buds. Both buds have small LED lights, which can be distracting to others when used in the dark. The end has a connection point for a lanyard or clip that might help make loss less of a concern.

They come with five different silicone tips, so there is something for everyone, and in our experience, finding the right size really impacts the overall comfort and how long they are comfortable to wear.

Pairing requires pulling them from the case and opening your Bluetooth on your device. We didn't have trouble pairing them with a first device, but if you want to pair them with more than one, you need to unpair them from the original device before pairing with a secondary device. This was really annoying when switching between a phone and computer; the clunky experience makes it a no-go for anyone seeking a multi-point connection.

These earbuds feel soft and comfortable, but our ears breathe a sigh of relief when we remove them. The long tips sit deeper in the ear canal than most, holding them firmly in place but creating more pressure, making them only okay. Despite the 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.

The IPX8 rating makes them a compelling choice for use in wet environments or during workouts. Theoretically, this rating means prolonged immersion in water up to a meter. They sport the highest rating for being waterproof in the group.

Making calls is where we loved the TOZO the most. While they struggled in really loud environments like the metro, they still put the caller's voices front and center, no matter the background clutter, so not much was lost. Calls weren't perfect, but it was better than most for the price.

We were underwhelmed with TOZO's sound quality. The cramped soundstage makes it challenging to separate or place individual instruments. There isn't enough clarity to pick out many details, leaving favorite songs devoid of luster. Gaming was a disappointment as well, as you can't hear auditory information around you.

Our Analysis and Test Results

Sound Quality

The Tozo mix does not sound natural, with dominant bass frequencies. Bass lovers might find it fun, but it lacks balance. The mid-range can sometimes hold its own, and the voices sound reasonably realistic. But, occasionally, they compete for space. The treble tones rise above the fray for the most part. They can sound thin, but are controlled enough to avoid distortion or piercing highs.

Charley Crockett's vocals in “Sad & Blue” are center stage as the funky organ and warm trumpet merge with the percussion. This song is a rhythmic bop, and the emphasized lows add energy to the mix. 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 into a mess. These earbuds certainly have a dramatic take, but it isn't a realistic one. They can get loud but lose clarity at higher volumes and detail at lower levels.

We map out the frequency response and chart it beside the GearLab House Curve benchmark for comparison. The TOZO frequency curve is elevated in the low and bass frequencies and spikes higher than the preferred curve in portions of the mid and treble ranges, which could explain its unnatural sound.

Comfort and Fit

The TOZO is not that comfortable. They feel heavy (but they aren't), and the tips are longer, making the ear canal feel full. Perhaps it is the feel of the longer tip putting pressure inside the ear canal as it tilts due to the weight. Discomfort soon follows. We only wore them for about 1-3 hours on average before seeking relief.

While they feel good at first, they are bulkier than most buds, and the design is a poor fit for those with smaller ears. However, the tip design did help keep them in place, and they stayed put better than other bulky buds.

Noise Cancellation

All earbuds offer passive noise isolation, but the TOZO T10 earbuds do not offer active noise cancellation (ANC). Our lab tests reveal that these earbuds can block between 10 and 40 decibels of background sound, even without ANC.

However, its passive noise isolation is shockingly effective, muting ambient sounds. We could barely hear office typing, and the treadmill hum was dampened. While the “earplug effect” is beneficial, the earbuds aren't comfortable enough for the passive trade-off.

App Features

These buds leave much to be desired, with a frustratingly cluttered 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 app you are about to download. It's so packed with features that it's hard to navigate, and many feel gimmicky. Thankfully, the adjustable EQ presets are easy to access from the home screen and are the most helpful tool.

The touch controls, including playback, volume, and calls, are customizable, but the default settings are intuitive. Digging deeper, you'll find odd features like a shop, social media interfaces, and an unsupported AI area.

Battery Life

While the manufacturer claims the TOZO should last 10 hours on a full charge, we eeked out 7 hours and 44 minutes.

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 provides reliable isolation of voices during calls. The voices have a hint of graininess, even in a quiet room. They were easy to understand with plenty of power and volume, though they aren't as natural and life-like as higher-priced competitors. They struggled somewhat in a moderately paced office, but we could still understand voices easily.
