Crafted with the modern audiophile in mind, the HD 6XX replaces the HD 650’s gray colorway with something darker and more dramatic: a deep midnight blue. The silver nameplates have been swapped for black plates with contrasting silver text—and the Massdrop logo is silk-screened on the inside of the headband, just above the right cup, with the serial number located just above the left cup. Based on feedback from the community, this iteration has also been updated with a detachable 6-foot cable (compared to the original’s 10-foot cable) and a ⅛-inch plug, which is more versatile for everyday laptop, phone, and DAP use than the standard ¼-inch plug. Of course, the HD 6XX comes with a ¼-inch adapter for those who want it.
