Selling my Sennheiser HD 6XX headphones purchased in late March 2018. Only have 2 hours of listening time on them. Include original Sennheiser box, manual, 6 foot detachable cable and adapter for home audio listening. Purchases though Massdrop for a total of $340 after shipping, currency conversion and customs.
Sound quality is for audiophiles which turns out....isn't my taste.
