I have a brand new, never removed from the box pair of Sennheiser HD-650 headphones for sale for $350 shipped. I bought these to replace my Hifiman HE-500 due to comfort issues, but hesitated to switch as I really enjoy the sound quality of the HE-500.
These were purchased direct from Sennheiser; I can supply an invoice if desired.
Please respond with any questions and I will do my best to answer.
