I own many,many pairs of iem's, but on rare occasion have a run across a pair that just seems to do everything perfectly. my vsonic gr-7 bass edition came close but still lacks with isolation. my rha 750's are excellent but still lack in the sub bass in my opinion. but these little yamaha's seem to be the best all around for me. best of all I got them on ebay for $56.00, money well spent for these jewels!
