Hi there, I've been using HD228 for quite some time now, but it's getting uncomfortable and doesn't sound as good as it used to etc, etc.. So I decided it's a time for a portable on-ear headphones. Now let me tell you that I really do like BASS. However, I'am not as much into it to sacrifice everything else, so I ruled out XB500's (they are not very portable neither..) After hours of reading I finally decided to get either UR-55 or S600. Which one do you think is better? Which one has more bass, better soundstage, more clarity... Which should be more comfortable? I'am aware that KOSS has little to no sound isolation, but I could probably live with that if they sound better than JVC. Also, is there any sense in these negative reviews? http://translate.google.lt/translate?hl=lt&sl=af&tl=en&u=http%3A%2F%2Fwww.digitalversus.com%2Fheadphones%2Fkoss-ur-55-p11760%2Ftest.html http://translate.google.lt/translate?hl=lt&sl=ga&tl=en&u=http%3A%2F%2Fwww.expertreviews.co.uk%2Fheadphones%2F1282846%2Fjvc-ha-s600 Or did they just tested them out of the box without burning them in? The impressions from forum members seem to be quite opposite... PS. For some reason direct links do not want to work, so used google ones instead.
