I have been hearing great thing about these Koss clip-ons, so i coughed up £12 and they arrived yesterday.
My normal daily phones are either px200 or groovecapped e888sps but i own lots SR60s, various sonys ex71, v300, 710lp, ed21lp, sennheisers psx60 , px200 , 400 and 500s, akg k26p. Nothing too expensive but a good mix.
These are the second best pair i own behind the SR60s and they are just behind them , i mean just...
They sound like my SR60s a lot, same airy reproduction , tight , smooth bass and lots of detail in the mids. The SR60s are slightly colder and more natural, i have read that with 40 hrs + burn in the ksc75s lose a little warmth and the bass calms down, this may even the score!
