These headphones sound great and are fine for sport but, and it's a big BUT, if you want to wear them lying down, sitting in a high backed chair (on a bus, train, plane, sofa etc) forget it! The band around the back of your head is pushed forward and dislodges the earpieces from their proper position. This is uncomfortable and destroys the sound. If this is not bad enough the insulation covering the wires started to come off after a couple of weeks of normal use. After one year nearly half the insulation has gone and the wire tangles and looks a total mess. These headphones have been on the market a long time yet nothing seems to have been done about this problem. I will never buy Sennheiser again.
