Massdrop has done some great things in the past few years, we've gotten some amazing collaborations that gave us the AKG 7XX and Sennheiser 6XX, more recently we got the Fostex T-X0 and the HiFiMan He-4XX. What's next? Will we ever see an electrostatic headphone? Maybe some Massdrop X Stax L3XX? L5XX? L7XX? Whatever it is, I can't wait to see what Massdrop will bring to the audiophile community.
