Customer Ratings & Reviews

Ear buds always fall out of my ears when I'm at the gym. These fit much better and have great sound quality for music and phone calls.

​I’ve been using the Tozo O2s for about two weeks now, mostly for running outdoors and wearing around the office. I usually struggle with in-ear buds (they fall out or hurt my ears after an hour), so I wanted to try the "open-ear" style without spending $150+ on the big name brands. ​These are very lightweight. Because they sit over your ear rather than in your ear canal, I honestly forget I’m wearing them. No ear fatigue even after a 3-hour session.The dual-axis rotation makes them very flexible. Since they do not block noise, I can have situational awareness as in hearing cars coming when I run, and I can hear my coworkers asking me questions without taking them off. I’m getting very close to the advertised time. The case holds a good charge, and I only have to plug the case in once a week with moderate use. The Tozo app is surprisingly decent. You can customize the EQ, which is necessary to get good quality audio. Mids and highs are crisp and podcasts sound fantastic. You can boost the bass in the app, but it will never thump like an in-ear monitor, which is expected. ​If you blast these at 100% volume in a quiet library, people sitting next to you will hear a tinny version of your music. At 50-60% volume, sound leakage is not an issue. The touch controls are very sensitive, if you have fat fingers like mine, control can sometimes become difficult. The bottom line is that if you want headphones for critical music listening or blocking out the world on a plane, do not buy these. But if you want a super comfortable pair of headphones for workouts, podcasts, or keeping an ear out for the kids/office while listening to background tunes, these are an unbeatable value for the price. ​

These headphones are very comfortable to wear, and they sound great. They have a full sound. The bass is decent. Great value for the pricepoint.
