I'm not sure where I stand on burn in with ba's people say they don't burn in and some say they do.. I know that my 535's sound better now and think I have around a 1000 hours.. Maybe a little less.. Maybe ba's just take longer to break in.. Don't know.. I know they do sound better now.. And maybe it in my head..
no you are right ..... my old shure se210 took approx that much to sound better than new (i noticed it mainly in the sound stage !) ..... as i am hoping for my new shure se535 cl to improve its sound too ... but any way it sounds great out of the box unlike the older ones which i hated out of the box !
