Sennheiser HD600 £151.20 / HD660S2 £228 Open Back Hi-Fi Headphones ( Refurb / Discount at Checkout )

Thanks to @Tacavas and @Alex_H for the spot - a fantasic price for both headphones. I feel tempted to get an HD600 to compare with my HD660S2! The discount applies at Checkout - my HD660S2 from the last time it was this price looked brand new.
The HD660S2 has the best bass of the HD600 series,but the HD600 is considered the best for vocals.
