I just read it but still hoping someone to chime in.
Anyway, I was also thinking about the headphones vs IEM issue. Aside from comfort (and fittings), how do they compare in bass performance? I mean, for me IEM has excellent noise cancellation because of total blockage in the ear. I haven't used a headphone before but I am thinking of buying one. For more or less $100, what good headphones has excellent bass performance and clarity?
Logitech UE 4000- Isolation isn't perfect since they are on-ear, but they have solid bass performance and clarity. This is the best price I have seen on them, don't know the retailer though.
