I want to buy...your HE-6s! Preferably in good condition. Please contact me with a full and complete description of the condition of your cans and your asking price.
I have no problem paying cash, but I also have a pair of Beyerdynamic T1s in MINT condition, recabled with DHC Nucleotide (nicest cable I've ever seen) and with matching J$ pads available for trade. The T1s come with original box and all accessories.
Check my feedback, I'm legit.
