I got a AKG Q701 black from an ebay seller 2 weeks ago. Since I don't have any other full-size headphones, I can only compare it with my Triplefi 10 in-ear and it doesn't sound noticeably superior as what I expected. Then I noticed the specifications printed on the retail box is really weird ( apparently it should be 10ft/20ft)
The serial number on the box is something like AK3007-043XX, the last 5 digits do match what is on the headphone though. Is there any chance this pair being a fake one?
