I had owned a Sony Ericson HBH-DS980 and an HBH-IS700. the DS980 rocked, can't say much for the latter. The BT3030 headset is great because I can workout in it and not worry about it while sweating. My DS980 broke because of the humidity, lol. the headphones that accompany it are garbage but if you get some sony's or skull candy you will be all set. All the controls work and it lasts sometimes longer than six hours. I totally recommend this if you are looking for a headset that is semi-classy while rugged, this would be the headset you take with you on a bike trail or in a conference meeting using the clip(which wasn't included in mine but it's cool).
