I use these headphones min. 2 times a week in fitness training and I'm thrilled. Whether I'm on the track or on the components: the headphones remain in the ear! What unfortunately in other products was not always the case. The cable is very long and can even for larger people easily make contact to MP3 players & Co in your pocket). I myself (160 cm) have always via cable, which I put in with your pocket. The sound thrilled. Compared to my previous headphones bass and treble are great spread here.
