The TOZO T12 Truly Wireless are a decent pair of budget-friendly truly wireless earbuds. They’re lacking in frills and features but have a sturdy, somewhat comfortable design. Their sound profile is excited, which delivers extra thump, rumble, and boom while vocals and lead instruments are bright. Unfortunately, their battery performance isn’t particularly impressive, their integrated mic is sub-par, and their deep in-ear fit may not suit everyone. Still, if you’re looking for a fairly versatile set of earbuds and don't want the hassle of a wired connection, they aren’t a bad choice.
Our Verdict
The TOZO T12 are alright for neutral sound. They have an overemphasized bass that creates a fair bit of boominess, but their amazingly well-reproduced mids prevent vocals and lead instruments from sounding overly muddy or cluttered. Their treble accuracy is satisfactory, though some listeners may experience a bit of harshness. Unfortunately, they don't have a companion app with EQ presets to personalize your listening experience. Like most in-ears, they provide a very closed-off, narrow soundstage.
- Bass-heavy but not overwhelming sound profile.
- No EQ in companion app.
The TOZO T12 are good for commute and travel. They’re small enough to be easily tossed into your pocket or a bag and do an excellent job of blocking out chatter from fellow commuters. That said, the rumble of bus and train engines may disturb your listening experience on the way home. They also don’t have an especially long continuous battery life, so if you’ve used most of their charge at work, you may have to put them back in their case. It's possible to listen to one bud at a time while the other recharges.
- Very good passive noise isolation.
- Sturdy build quality.
- Remarkably low audio leakage.
- Short continuous battery life.
The TOZO T12 are great for sports. They feel sturdy, have a secure fit that shouldn’t fall out of your ears, even during moderately strenuous exercise, and are certified IPX8 for protection against water immersion. Meanwhile, their bass-heavy sound profile should keep you pumped up during your next workout session, while their intuitive control scheme lets you make simple adjustments without interrupting your rhythm.
- Stable fit.
- Sturdy build quality.
- Bass-heavy but not overwhelming sound profile.
- Short continuous battery life.
The TOZO T12 are alright for office use. They do an outstanding job of blocking out the chatter of coworkers and the high-pitched hum of a noisy AC unit, meaning you can stay focused on your work. They also barely leak any audio, so even if you’re the type to blast your music at high volumes, you won’t disturb people nearby, even in a quiet workplace. Unfortunately, their 5.3-hour battery life won’t last you the day without a stint in their charging case. Meanwhile, their deep in-ear fit may become a little fatiguing during longer listening sessions.
- Very good passive noise isolation.
- Remarkably low audio leakage.
- Short continuous battery life.
- No multi-device pairing.
The TOZO T12 can connect to Bluetooth-enabled PCs, but their audio latency is a little too high for them to be well-suited for wireless gaming. They also aren’t compatible with PS4 and Xbox One consoles.
The TOZO T12 are Bluetooth-only, and you can't use them with a wired connection.
The TOZO T12 are passable for phone calls. While your voice should sound somewhat natural over the line, it’s perceived as being thin and muffled. Their integrated mic also does a mediocre job of isolating speech from background noise, so people may have a hard time understanding you if you call from a noisy or crowded environment. Thankfully, you should hear people talking to you more clearly as these in-ears do a very good job of passively isolating you from background noise.
- Very good passive noise isolation.
- Mediocre noise handling capability.
