Have the Head Set buy because of the other reviews. Have no regrets. In sports these things sit quite well. Initially, the stakes have something pressed. The material is aging but is a bit softer and. Meanwhile, there is however quite frequently that the stakes disengages from the speakers. The problem with the volume control, I did not because I did not press the switch. Control the action with me over the phone. Sound of the sets is ok. You use it so the sport - I at least. Since you have some noise from the outside. The Speaker, however, are relatively close. One should be cautious and sound control somewhat down while wearing the road. Otherwise, you get rings from happening to not much with.
