I subscribe to Massdrop's updates, honestly finding that there's little upside for me to buying one of their drops. I missed out one of their drops late last year, being a fan of certain products. An email was sent out for an added queue to their second limited-run drop of Massdrop's Sennheiser 650, called the 6XX with a shorter cable (2m instead of 3m), different connector (1/8-inch mini-plug connector instead of full size plug), and different color (midnight blue).
The drop extension includes the $199 price. The only downside is the 12/18/17 delivery date. Made in Ireland, no shipping cost, same 2-year Sennheiser warranty. I ordered one before posting here. A no-personal-affiliation link here with Head-Fi's review embedded:
