This headphone is just one purchase short of fully unlocking and it should easily do so with 15 days left in the offer, it is the new condition AKG K181 DJ UE closed-back on-ears going for $55 plus $8~ flat shipping with a late September 2016 release estimate.
Speaking of AKG DJ headphones, the K167 TIESTO DJ, in new condition, goes for $55~ with free shipping with a limit of three units per customer at Amazon by Amazon actual.
And while we are talking Massdrop, another offer fully unlocked, it’s “just” cables, no, not the magical kind, but the utilitarian kind, the MEE Audio MMCX Cables going for $25 plus $3.50 flat shipping. Earphones NOT included. This offer has eight more days to go and ships in late September 2016.
Speaking of magical audio improvements, did you know that there’s now magical “file copying technology” that improves sound quality? Yes, the soul of the music is recaptured and reconstructed in the buffers in otherwise bit-by-bit identical music files. Because it’s the soul of the music! /sarcasm
