ONIKUMA GT889 Gaming Headset

The ONIKUMA GT889 is an over-ear gaming headset with a detachable microphone and three connection modes: 2.4 GHz via the included USB receiver, Bluetooth 5.4 and a wired connection. It features 50 mm drivers, RGB lighting and a built-in battery rated for up to approximately 60 hours of playback. The headset is compatible with PS4, PS5, Nintendo Switch, computers running Windows 10 or Windows 11, and macOS devices. It is suitable for gaming, listening to music and making calls.

Three Connection Methods

In 2.4 GHz mode, the included USB receiver provides low-latency wireless transmission for fast-paced gaming. Bluetooth 5.4 enables wireless connection to compatible devices, while wired mode offers an alternative when you prefer not to use a wireless connection. The wireless range is approximately 15 m.

50 mm Drivers and Communication Microphone

The 50 mm drivers have a frequency response of 20 Hz to 20 kHz, making the headset suitable for gaming, music and films. The detachable microphone is mounted on a flexible boom for convenient positioning during conversations. It features noise cancellation and can be controlled directly from the headset, so you can mute it without opening settings on your computer.

Controls and RGB Lighting

Dedicated controls on the ear cup allow you to adjust the volume, manage playback, skip tracks, and control the microphone and lighting. RGB lighting is located on the outer ear cups and the flexible outer frame of the headband; the inner headband that rests on the head is not illuminated. The lighting can be switched off to suit your preference.

Battery and Comfort

The built-in battery provides up to approximately 60 hours of playback. Charging takes approximately 2–2.5 hours via the USB-C port, and the specified power input is 5 V / 600 mA. Soft, breathable ear cushions are designed for comfortable wear during extended gaming sessions.
