The quality is not that good, especially when comparing to other bluetooth stereo products. Very uncomfortable. Ear area is designed for very small ears. Mine are not huge, normal size, and after 30 minutes of listening I have to readjust because my upper ear becomes very sore. Outside of that, they do what they are designed for. Play music. No issues with it disconnecting when I move. Short battery life (approx 6-8 hours listening time).
