Massdrop offers preorders of the Massdrop x Sennheiser HD 6XX Headphones in Midnight Blue for $199.99 with free shipping. That's tied with our mention from two weeks ago and the lowest price we've seen. (It's also $116 less than the best deal we could find for the similar Sennheiser HD650 headphones.) Deal ends July 30.

Based on the classic Sennheiser HD650 Headphones, these extremely well-reviewed open-back headphones feature the same drivers and architecture, updated with a 6-foot detachable cable with 3.5mm plug and midnight blue colorway. They offer a 10Hz to 41kHz frequency response, 300-ohm impedance, and aluminum voice coils.

Note: They have an estimated ship date of December 18.
