So my friend is looking to purchase these Senheiser RS 170s (http://www.sennheiserusa.com/wireless-headphone-stereo-surround-sound-headphones-502874). I'm more into hometheatre setups and could use your advice on equally priced, but perhaps better, wireless, closed cup headphones. He will be wearing them during work hours so they should be comfortable and relatively isolated. He listens to electronica, ambient and female vocal music, so I'd say something clear and crisp on the treble (he enjoys detail) and with decent bass and midrange obviously. Also if the Senheisers are the way to go, I just want some second opinions to confirm this, but nothing more expensive than them ($280). Thanks guys!
