I have a set of Sony MDR-V200's (I think) that I've had for about 10 years, and a set of Panasonic in-ear headphones. The sony's are alright.. bass heavy. Definitely far from accurate! The Panasonic's are pretty well the opposite.. I bought them over Sony's in-ear phones because I did a bunch of research and they're supposedly more accurate. I'm not sure if that's really what I want anymore though.. a little extra kick in the low end would be nice sometimes. I still like them for around-town headphones though, especially for the price!

I've been shopping for a set of proper studio phones for a while though for my musical dabblings, but I've never gotten around to it. I've used the Sony V7506 in a few different places and found them comfortable, but I've never A/B'ed them with anything else.

ps. I can't ride with in-ear headphones. I need my hearing!
