Drop took the Koss GMR-540-ISO gaming headset and made it lighter and more affordable. The GMR-54X-ISO features the same audiophile-grade 3D sound as the 540. It also has a detachable cable with inline mic, while the detachable boom mic has a new mute and volume switch.
THE BEST Koss
Based on the 1984 classic lightweight headphones, Koss and Drop teamed up to build a new version, designed for better durability, with modern components, and an inline mic for calls. They weigh just 2 ounces, and have an adjustable comfort band, and offer an impressive 15 Hz–25 kHz frequency response.
