The headphones were ok while they worked, sound quality was OK, no headaches, light and comfortable fit, 3-4 hors of battery life. They did the job, and allowed me to hear traffic while running on the streets, but about 2 weeks of use for 60-90 min workouts they stoped charging, and now only turn on with the charging cable pugged in. Seller never responded to the support inquiry. I guess buying the AfterShokz would've been a safer choice from reliability point of view.
I like this a lot. At higher volumes the mini-speakers start to vibrate and bounce off the sides of your head which might be slightly annoying, but you normally usually wouldn't need such a loud volume. It's very comfortable and can be worn for several hours. Edit: 3 months later, still my favorite pair of earphones. good battery life too, about 4-5 hours of use.
