Description

The Cosmic-III Lite Black wireless headset from Armaggeddon is designed to cover both gaming and audio-listening needs with a strong feature set and smart design. The over-ear cups use premium PU leather with effective passive noise isolation, while the adjustable headband ensures a secure fit for long sessions. The detachable omnidirectional microphone gives you clear communication when needed and can be removed for simple music or media use.

On the connectivity side, the tri-mode design means you can switch between Bluetooth 5.3 for mobile and tablet use, a 2.4 GHz wireless dongle for lag-free PC/console gaming, and a wired AUX input when battery is low or you prefer a direct analog connection. With drivers sized at 40 mm and a frequency range spanning 20 Hz to 20 kHz, you're getting the kind of performance expected from true over-ear headphones, not just a budget wireless set.

Battery life sits at up to 20 hours at 50 % volume and recharging takes approximately 2.5 hours via USB-C.
