I purchased the BestSkinsEver. It covers the whole phone. I then purchased the Marware Sidewinder.

I like the combin of the two items. I wanted to use a belt clip and carry the headphones with me. This works out great. I use my Bluetooth headset to answer calls most of the time but if I do want to jam on music I have the headphones with me and they are not twisted and tangled.
