I mentioned this on the headphone thread, but thought I should probably put it here as well before putting them up on trademe this weekend.
I'm selling an almost brand new pair of Massdrop Sennheiser HD 6XX headphones - effectively the HD 650 but with a midnight blue finish, 6ft rather than 10ft cord and a 1/8-inch plug (though has an adapter to make it 1/4 inch).
I’ve probably only listened to them for three hours in total, and although they are definitely better than my Sennheiser 598SEs I just don’t use them. Basically the tiny portable dac-amps I normally use aren’t enough to make the 6XXs sound better than the 598s when I’m on the move, and thanks to a new home speaker setup, my static use of headphones has basically stopped.
They are open-backed headphones, so don't provide noise isolation, and do require a reasonably good amp to sound their best.
The HD650 usually retails at well over $600 here, which makes these a deal at $300+shipping (or I can drop-off in central Wellington).
