I have a pair of Sennheiser HD600 cans for sale, asking $200USD shipped in USA/Canada. They are in immaculate shape and include the original inner and outer boxes. The inner box has a tiny strain mark at the corner of the lid, otherwise the box and headphones are perfect. These cans sound great, but are just not the sound for me.
I live in Vancouver, BC, so if any Head-Fiers around here are interested, let me know.
