These are some of Massdrop's most-requested headphones. They're expected to ship at the end of August.
Brad's Deals Editor Jim,
These open-back Sennheiser HD 6XX Headphones listed at $499.95, but you can get them for $199.99 when you order with a free account at Massdrop. Shipping is free. That's the best price we can find anywhere by about $116, and it matches the best price we've ever seen for this style. The 6XX model is based on Sennheiser's HD 650 headphones, only they're designed especially for Massdrop. I regularly use these with an amp and DAC, and they have the best sound stage of any headphones I've ever heard. Note: Once you sign in as a free member and join the drop, you'll be charged on or before 4/28. The headphones are expected to ship on 8/30. Sales tax is charged in most states.
