For sale is a pair of Massdrop K7XXs. I paid $200 + $25 shipping, and also €50 import duty.
They are of course in mint condition only used for an hour or so. No rattle whatsoever. They just don't do it for me, I prefer my Denon D2000s. €250 shipped, you pay paypal fees. Located in EU. Registered post. In original packaging with invoice for 2 year warranty.
