think i'll get myself a pair of cx400's £20 is cheap as chips for decent earphones
my sony ex71's are falling to bits now (had them about 4 years, and i really don't take any care of them)
I had the Sony ex71s, do you find the wires tangle for fun? Every time i got them out of my pocket i had to spend 5 mins untangling them. They had good sound though, was gutted when they fell out of my ear and got tangled in my bike gears

The Sen cx300s sound better IMO so the later models cx400 or 500 should be a good upgrade.
