The Aurisonics Kicker is one of the metallic coated ones?
I've owned a lot of metallic coated headphones over the years. Got rid of all of them pretty fast and now I just avoid them... that said I still want to try the kicker.
I had one set of Ultrasones I liked but I ended up selling them. They had pretty decent bass, I don't remember exactly what I didn't like a lot about them.
@Whataudiophile Only if you find a used MDR 7550 that cheap, which won't be easy, aside from that the 90EX is the best i know of, I honestly still use it almost daily.
