This is some good information, never even thought about in a car. Especially if driving alone, I'm sure it would be more enjoyable...

I've been lurking for awhile, I was going to get into headphones, but we just invested well over $1000 into a new home audio system, so I figure I should wait until the excitment form that wears off Anyways you guys seem to know what your talking about, so when I read that a lawnmower could...

Well a neat idea anyways I'm kind of curious about the setup now (we just got a sub for our stereo system and we have the speakers running through the sub so it filters out the low frequencies.) How would a sub be set up with headphones?

Sadly my budget is umm...expiriencing a mild drought. So no etymotics at that moment. But I am in the market for a decent earbud. I'm looking for some opions from you guys. They are going to be driven by a RIO PMP300 MP3 player with no amp (MP3's at 56k). Any advice would be greatly appreciated!
