This pair of the HD600 have been rarely used, less than 10 hours total I would say. They just don't hold their weight against T1 or LCD2 IMO. They've been sitting in the box provided by Sennheiser while not in use. I've really just been procrastinating on selling them. I can include more pix upon request.
The price is $270 + shipping and paypal fees. I would prefer to sell them locally on Long Island to avoid shipping and fees.
