Product Description
The ONIKUMA GT811 Head-mounted Dual Noise Reduction Wireless Bluetooth Headphone combines dual-chip active noise cancellation, low-latency audio transmission, and high-fidelity sound reproduction for competitive gaming, remote work, and travel. Built with an ergonomic headband and plush memory foam earmuffs, the GT811 provides exceptional passive sound isolation and all-day wearing comfort.
At the core of the headset is an advanced ANC+ENC dual-chip hybrid noise reduction system. The Active Noise Cancellation (ANC) actively suppresses ambient external noise such as office chatter, engine hums, and transit sounds, while the Environmental Noise Cancellation (ENC) filters background room chatter from your voice to keep microphone calls crystal clear.
Acoustically tuned with high-precision 40mm dynamic drivers, the GT811 outputs balanced sound with punchy bass response, warm midrange clarity, and crisp treble across a 20Hz–20kHz frequency spectrum. Powered by Bluetooth 5.4, it maintains a stable wireless connection up to 15 meters and delivers an ultra-low 60ms audio latency mode for real-time audio synchronization during fast-paced gaming.
Equipped with a 500mAh internal battery, the GT811 offers up to 55 hours of continuous playback on a single charge and recharges fully in approximately 2 hours via USB Type-C. For maximum setup versatility, it supports both wireless Bluetooth 5.4 operation and a zero-latency 3.5mm wired AUX connection across desktop PCs, laptops, mobile devices, and consoles.
