ONIKUMA X91 RGB Wired Over-Ear Gaming Headset with 50mm Drivers & Noise-Reducing Microphone – Black

Immerse yourself in games, music, movies, and team communication with the ONIKUMA X91, a wired over-ear gaming headset combining powerful 50mm audio drivers, RGB lighting, a flexible noise-reducing microphone, and comfortable closed-back earcups.

The X91 uses a standard 3.5mm audio connection for sound and microphone communication, while a separate USB connection powers the RGB lighting. This makes it suitable for gaming PCs, laptops, PlayStation, Nintendo Switch, compatible Xbox controllers, and mobile devices equipped with the appropriate 3.5mm headset connection.

With its 20Hz–20kHz frequency response, 113±3dB sensitivity, 20Ω impedance, 2.2m cable, adjustable headband, and breathable over-ear cushions, the X91 is designed for extended gaming and everyday multimedia use.

Key Features

50mm Hi-Fi Dynamic Drivers

The ONIKUMA X91 is equipped with large 50mm dynamic speaker drivers designed to provide powerful gaming audio.

The drivers help reproduce:

• Deep game effects
• Clear dialogue
• Detailed footsteps
• Music and environmental audio
• Strong bass response
• Clear mid and high frequencies

The large driver design makes the headset suitable for gaming, movies, music, and voice communication.

Stereo Gaming Audio

The X91 delivers conventional stereo audio through its 3.5mm connection.

Stereo positioning can help distinguish left and right directional information during gameplay, while maintaining broad compatibility without requiring proprietary surround-sound software.

20Hz–20kHz Frequency Response

The headset covers the standard full-range audio spectrum:

20Hz – 20kHz

This provides reproduction across bass, midrange, vocals, effects, and higher-frequency details.

Omnidirectional Noise-Reducing Microphone

The integrated flexible microphone uses an omnidirectional pickup pattern and is designed to provide clear communication while reducing unwanted environmental noise.

Suitable for:

• Multiplayer voice chat
• Discord
• Online gaming
• Team communication
• Voice calls
• Online meetings

The microphone can be repositioned for more comfortable placement near the user's mouth.

360° Flexible Microphone

The microphone arm can be bent and positioned according to the user's preference.

This makes it easy to:

• Bring the microphone closer for clearer speech
• Move it away when not required
• Adjust the pickup position for different users

RGB Gaming Lighting

The X91 features colorful RGB lighting effects built into the earcups.

ONIKUMA markets the lighting system with flowing multicolor effects designed to complement RGB gaming setups.

The RGB illumination is powered through the headset's separate USB connection.

3.5mm Audio + USB RGB Power

The X91 uses two connections for different functions:

3.5mm Jack
Carries headset audio and microphone communication.

USB
Provides 5V power for the RGB lighting.

This distinction is important: USB is primarily for the LED lighting and is not required for normal 3.5mm audio playback.

Wide Device Compatibility

Through its standard 3.5mm connection, the X91 can work with compatible:

• Windows gaming PCs
• Gaming laptops
• Mac computers
• PlayStation 5
• PlayStation 4
• Nintendo Switch
• Xbox controllers with 3.5mm headset support
• Smartphones with headphone ports
• Tablets

Some PCs with separate headphone and microphone sockets may require the included or a compatible splitter cable.

Devices without a 3.5mm port require an appropriate audio adapter.

Closed-Back Over-Ear Design

The X91 uses closed over-ear earcups designed to surround the ears.

This helps provide:

• Passive isolation from surrounding noise
• More focused game audio
• Reduced sound leakage
• Comfortable long-session use

The headphones themselves do not provide electronic Active Noise Cancellation (ANC).

Breathable Padded Ear Cushions

Soft over-ear cushions are designed to provide comfortable contact around the ears during extended gaming sessions.

The breathable design helps reduce discomfort and heat buildup during longer periods of use.

Adjustable Headband

The adjustable headband allows the headset to accommodate different head sizes.

Its suspension-style design helps distribute pressure more evenly across the head.

Quick Volume Control

Integrated volume adjustment provides convenient audio control while gaming.

This lets users change the listening volume without constantly opening Windows, console, or application settings.

Long 2.2m Cable

The X91 uses an approximately:

2.2 ± 0.15m cable

providing enough length for desktop PCs and gaming setups where the system is positioned away from the user.
