The Massdrop x Beyerdynamic DT 177X Go headphones redefine portable audio excellence. These closed-back headphones combine sleek design with outstanding sound quality, offering a perfect balance of detail and punch in a compact form. The plush, comfortable ear cups ensure extended listening without fatigue, while the durable build makes them ideal for on-the-go use. For audiophiles seeking premium sound on the move, these headphones are a game-changer.

"A collaboration with world-renowned headphone manufacturer Beyerdynamic, the DT 177X GO has the kind of German-made quality you can see, hear, and feel. Based on the DT 1770 PRO, it uses the latest generation of 45-millimeter Tesla drivers for a wide frequency range and a weighty, controlled bass. We smoothed the response slightly while retaining the punchy sound that’s made the DT 1770 PRO a favorite in recording studios. With 32-ohm impedance, it’s easy to drive from portable sources without an amp, while the office-friendly closed-back design ensures your music won’t disturb your neighbor—and vice versa. The four-pin mini-XLR connection allows compatibility with balanced cables. For unrivaled comfort, you’ll get two pairs of premium Dekoni earpads—one sheepskin and the other velour—totally free."
