Very bad headphones... You can't hear well when talking on the phone. Others can't hear you either... When I listen to music with the volume at max, it's not enough. It's like having the volume at half compared to other headphones. The sound quality is very poor. And the icing on the cake is that even though I bought black ones and the box said they were black, the headphones were silver... Stay away! It's better to get a vuvuzela and attach your phone to it.
