[Hampshire] [OT] Recommendations for quality audio earbuds.

Back in September last year I bought an iAudio u3 MP3 player after
Samuel Penn pointed me to iAudio. I am very satisfied with it as it
gives good quality audio from the supplied earpieces but I find these
get a little uncomfortable after a while. My son has a pair of
Sennheiser CX400 but when I tried these I did think the quality was
anywhere near as good as those supplied with the iAudio.

Does anyone have any recommendations? I do not need noise cancellation.
