I have been using the headphones for several weeks now and think they are completely overrated. The sound is just good enough. The cable sheathing is too stiff for my taste, which is annoying when moving. A softer plastic could have been used, as with other suppliers. The control lump on the cable is also annoying. Although the ear hooks hold the headphones to the ear, they are still far too loose in my opinion. Even the smallest ear rubber is far too big for my ear opening and keeps slipping out. I miss my old Plantronics Backbeat sports headphones. They held perfectly and the sound was better.
