Up for sale is my nearly new K7XX.
Received from Massdrop about a week ago and I've only listened to it a few times. Maybe 10 minutes total. Compared with some of my other headphones, I just don't like it as much as I used to (and AKG's never really fit my head that well). Mine is serial #174 and still has the plastic around the earcups. Everything included.
Asking $OLD paypal, shipped via Priority. Fees on me. Ships day after payment.
Thanks for looking.
