Product Description
You don’t have to pay like the pros to play like the pros. Our latest collaboration with Koss is an audiophile-approved gaming headset with Drop-exclusive upgrades you won’t find anywhere else.

Hear It All, so You Can Win Them All

Hear your favorite games and tracks like never before with the Drop + Koss GMR-54X-ISO gaming headset. Based on a popular Koss headset, the GMR-54X-ISO pairs a closed-back design with custom-engineered acoustics for truly immersive 3D sound. When gaming, the headset delivers positional cues to help you hear enemies from all directions. When listening to music, you’ll get a fun, punchy sound that does your favorite tunes justice. It’s the best of both worlds.

Small Adjustments That Make a Big Difference

After testing the original version, we reduced some tension in the already-lightweight headband for extended comfort during long gaming and listening sessions. What’s more, our version comes with a cord splitter, plus a boom mic with a new volume/mute switch for quick adjustments on the fly. With these upgrades, you never have to pause the action to change the volume, and you can plug the boom mic into a PS4, Xbox, Nintendo Switch, or other console without hassle. Crafted in a subtle, midnight blue colorway, our GMR-54X-ISO won’t call too much attention in the office or on the streets.

About Koss

If we were to write a history of audio companies in the US, Koss would land on the first page. Not only did the Milwaukee, Wisconsin–based company make the world’s first stereo headphone—the SP/3, in 1958—it’s also responsible for the first self-energizing electrostatic headphone, the first dynamic headphone to deliver all 10 audible octaves, and a standard-setting infrared wireless headphone. Over the years, Koss headphones have made it onto Air Force One, into the Smithsonian, and onto the heads of such music icons as Neil Diamond, Tony Bennett, and Pete Fountain. Founder John C. Koss was inducted into the Audio Hall of Fame in 1979 and the Consumer Electronics Hall of Fame in 2000.
