I chose these headphones to accompany me during my running, very loyal and satisfied the Creative brand for several years. I was very pleasantly surprised: overall very serious natural, settled once the equalizer, we get a really amazing sound reproduction! Tested with electro, metal and drum'n'bass, you simply can not wait for better headphones for sports at this price! Maintaining is there, we shake your head in any direction, it does not move! The flexible branches will suit several sizes of ears. Completely satisfied!
