SONY Stereo Headphones MDR-EX500SL BLACK | Inner Ear Headphone (
[027242706798]

I bought these to replace my old earbuds which had decent sound, but became uncomfortable after about an hour. Surprisingly, these headphones don't have that problem. Though they're bigger and heavier, they're quite possibly the most comfortable in-ear headphones I've ever used. In addition to being comfortable, these headphones sound fantastic. The 13.5" driver provides excellent bass response while still offering up clean, crisp highs. I feel comfortable saying that these are on par with, if not better, than the more expensive Shure SE210's and come without the epic learning curve (the fit of Shure headphones takes a while to get used to).
In my opinion, these buds are well worth the money. I'd highly recommend you give them a try. You won't be disappointed.
