I already have a pair of nice headphones that I use at home or for long trips, but I need a new pair for every day use. I always carry my ipod in my pocket wherever I go, and of course need headphones to go along with it. I've been going through a new pair like every 4 months and I'm getting sick of it. Is there a good pair of durable headphones out there? Preferably one of the IEM variety with good sound quality and at a reasonable price.
