Before you drop $300 on a fancy celebrity endorsed set of headphones, you might be better served trying the iWOW-U from SRS Labs and your existing headphones. That's what I did, with a $20 pair of Sony headphones and the sound quality was significantly better. The iWOW-U is a 3.5mm extension cord but with a twist. It includes a powered amplifier that enhances the sound quality and does a great job of stereo separation... I was skeptical, but the improvement was immediately noticeable and I am a tough cookie to please.
