Nope woops. sorry about that.. I've decided that i'll buy for home use headphone for under 100 bucks and another pair of earbuds for portable.. the reason i was against earbuds was that they damage the ears and because i'm a musician i can't afford this to happen. also i had a bad experience with earbuds. after a periot of time one side would drop dead. i can't see there firms like panasonic ,jvc and so on. any recommends earbuds execpt the RP-JE50? By the way, what is the defference between ::Full-size supra/circum-aural:: and ::IEMs/canalphones (closed in-ear):: thanks alot and sorry for the double posting.
