The ONIKUMA B15 Tri-mode Wireless Gaming Headphone is a versatile gaming headphone designed for users who want wireless freedom, low-latency gaming performance and flexible connectivity. With Bluetooth 5.3, 2.4G wireless and wired modes, a 50mm driver, RGB lighting and a large 1000mAh rechargeable battery, the B15 is suitable for gaming, music, movies, streaming and everyday entertainment.
50mm Gaming Driver
The ONIKUMA B15 features a 50mm driver with a 20Hz–20kHz frequency response, designed to provide immersive stereo audio for gaming and multimedia. The listed impedance is 32Ω ±15%, while sensitivity is specified at 116dB ±3dB by current Bangladesh listings.
Tri-mode Connectivity
One of the main advantages of the B15 is its three connection modes. It supports Bluetooth 5.3, 2.4G wireless and wired connectivity, allowing users to switch between different connection methods according to their gaming or entertainment needs.
Low-Latency 2.4G Gaming
The 2.4G wireless mode is designed for gaming with less than 30ms wireless delay, helping keep game audio closely synchronized with on-screen action. This makes the B15 suitable for fast-paced gaming where responsive audio is important.
Long-Lasting 1000mAh Battery
The ONIKUMA B15 is equipped with a 1000mAh rechargeable battery. Current Bangladesh listings specify up to approximately 55 hours of battery life with the RGB lighting turned off. Actual runtime can vary depending on connection mode, volume level and RGB usage.
RGB Gaming Lighting
The B15 includes multicolor RGB LED backlighting that adds a stylish gaming aesthetic to the headphone. The RGB lighting is especially suitable for users who want their gaming peripherals to complement an RGB-equipped setup.
Detachable 360° Adjustable Microphone
For gaming communication and voice chat, the B15 includes a detachable 360° adjustable omnidirectional HD microphone. The flexible microphone design allows users to position the microphone conveniently for communication during multiplayer gaming and online calls.
IPX4 Water Resistance
The ONIKUMA B15 is listed with an IPX4 water-resistance rating, providing protection against water splashes. It is designed for everyday use, although IPX4 protection does not mean the headphone is waterproof or suitable for submersion.
Wired Mode with 2-Meter Cable
Alongside its wireless modes, the B15 supports a traditional 3.5mm wired connection. A 2-meter cable is listed for wired use, giving users an additional option when wireless connectivity is not preferred or available.
Wide Device Compatibility
The ONIKUMA B15 is listed as compatible with PC, computers, Xbox, mobile phones, iPhones, iPads, tablets and laptops. Compatibility and available connection modes can vary according to the individual device.
Comfortable Gaming Design
