I have a pair of ATH-A500 that i want to sell as i dont really need them anymore. They dont include the box or the 1/4th inch adapter (unless i can find it). They sound great and there is only two small scratches on the right side, along with a tiny white spot. The cord is in great condition and they run great, I'm asking 65$ for them and an extra 10$ for shipping (If you live in florida near the seminole area you can come pick them up). There about a year or so old and I'm uncertain how many hours i've put on them (but its alot, heh).
I'll accept paypal (which i may need some help on) or you can come pick them up if your in the area.
