So, head-fi, I have been wanting to pick one or two cans out of this line for a while now, ever since my brother got the 203's. I was wondering what the pro's and cons were of the separate headphones... I heard the HD 201's have the right amount of bass, while lacking isolation... Whereas I heard the 202's bass sounds boomy and rather annoying... I haven't heard much about the 203's though... I tried them on and I like them. Anyways, if I were to choose two of the three headphones, which would you recommend?
