well I have sennheiser HD 465
these:
and I really like 'em ! I've had 'em for a year now and they're so awesome.
they cost about 80-90€ ~ as new. and I have a namie amuro PLAY sticker on 'em 
my best headphones ever, I could keep em' on for 100 hours.
when I'm travelling I just use some ipod headphones, they're actually quite good if you compare to creatives.
