Like the MW07 GO, the GO.DROP earphones are made to move. Crafted from TR90 composite, an ultra-strong performance material used in professional sports eyewear, they’re Master & Dynamic’s “most lightweight and durable earphones yet.” IPX6 waterproof, they come with M & D’s patented silicone Fit Wings and eartips for optimal comfort. Inside each earphone, custom 10-millimeter Beryllium drivers deliver rich, expansive audio across the frequency spectrum. Bluetooth 5.0 with support for aptX and SBC codecs ensures excellent signal transmission up to 100 feet, while a charging case holds an additional 12 hours of battery life. On this exclusive, each earphone is finished with sleek gray stripes: light gray over dark gray on one, and the inverse on the other. Paired with an all-black charging case, it’s a subtle look that deviates perfectly from the standard.
