Bought new from PJ Hi - Fi in Guildford 21st March 2015, just over a year ago. I have box and receipt with registered serial number. They are in as new in condition as was an impulse buy. Pics don't do them justice, they really do look brand new. Been boxed for last 4 months and had very little use since purchase. Cash on collection only and for serious buyers, I will demo though my DAC to test. Looking for £750.00 but price negotiable. I simply don't use them so highest offer nearest to my price. 01483 832765 01483 8327...(click to reveal full phone number) 07951553378 079515533...(click to reveal full phone number) Thanks http://en-uk.sennheiser.com/dynamic-headphones-high-end-around-ear-hd
