Sennheiser HD 600 Headphones ?

Sennheiser HD 600 - Open Monitoring Headphones Used but in excellent working condition - fully boxed! Used them for digital keyboard but have to sell off the equipment due to lack of time. These are the BEST headphones I have ever had in my possession. Superb quality, comfort and performance!
