Beats headphones Studio edition
New still in box, but I did just try it to make sure they still workI bought these a few months ago for $300 and I've never used themThese are not the wireless version but the Studio version which is double cabled for higher sound quality and power. While it can be used while on the go it's intended for strong audio in a recording studio or while gaming.The wired version does still have a rechargeable lithium battery inside. You don't need to keep the power wired during the whole use.
