Selling a used condition O2 amp. Comes with 3.5mm cable and wall wart.
Looking for Philips Fidelio L1, Vmoda M100, NAD VISO HP50,
No functional problems. Other than being scratched up, most of the screws are stripped. I use it as a desktop amp that is always plugged in and has never left my desk. It's not like the O2 was ever supposed to be a glamour product :)
