The sound is passable, understandably considerably thinner than in larger on-ear or over-ear models, which play in a different price league. Is operated via a pretty small button at the upper end of the cable. Pause (press once) or to accept a call, works well. With twice you can jump a track forward. With practice also manages the Press three times durz to skip back one track., Is no longer possible for me personally but. Ok, that's bearable.
All in all ok, albeit with minor limitations. The price can look past it.
