Built for ultimate versatility, the OG Series features Three-Mode Connectivity (Bluetooth 5.0, 2.4GHz Wireless, and Wired USB-C), ensuring seamless multitasking across Windows, Mac, and Android devices. It is powered by a massive 4000mAh battery that can last up to 400 days in power-saving mode, freeing you from daily charging anxiety. Whether you are a gamer or a creative professional, the Hot-Swappable PCB allows you to customize switches without soldering, while the dynamic 16.8 million color RGB backlight adds a vibrant modern touch to the classic look.
