COLO GCS is a new 7.1.2 channel speaker system designed for PC. It is installed directly on the backrest of the game chair. 11 independent speakers, including Dolby Atonomic technology, can create an immersive 3D sound field without taking up additional space on the desktop. The U-shaped ergonomic design, with shoulder-mounted speakers and avant-garde appearance, can perfectly integrate into the game setting without affecting the field of vision. case from the official website of the red dot, only for case sharing.
