Hey I'd like to give the hd650's a try. If anyone wants to try the hd600's I'd like to trade with you. This is NOT a sale, I only want to trade for hd650's. Mine are in good condition, work well, look good. They will come with no cable as I want to keep the cardas for the 650's I will be willing to pay $cash in addition to the phones. Let me know. Thanks.
