360° Omnidirectional Pickup
Built with 4 unidirectional microphones that form a true 360° sound pickup pattern. It captures voices clearly from all directions within a 4-meter radius, ensuring every participant is heard without needing to move closer. When paired with an external expansion microphone, the pickup range extends to 6 meters—ideal for conference rooms sized between 15–40㎡, such as small to mid-sized meeting spaces or huddle rooms.
Long Battery Life & Reliable Performance
Powered by a built-in 2000mAh rechargeable battery, this microphone provides over 4 hours of continuous operation and up to 7 days of standby time. Whether for long online meetings, hybrid conferences, or business travel, it delivers dependable power without frequent recharging, keeping your communication smooth and efficient.
Advanced Audio Processing Technology
Integrated with cutting-edge audio algorithms including ultra-depth full-duplex echo cancellation (up to 65dB), dual-direction dynamic noise compression (18dB), and intelligent automatic gain control. These technologies eliminate echoes, reduce background noise like air conditioning or typing sounds, and balance voice volume for clear, natural, face-to-face-like communication—even in acoustically challenging environments.
Dual Connectivity & Wireless Freedom
Supports both Bluetooth and USB connections for flexible conference setups. It can connect wirelessly to smartphones, tablets, or video terminals via Bluetooth, or directly to PCs through USB for plug-and-play use. With no need for additional cables or drivers, users can easily start a meeting anytime, anywhere—perfect for modern offices and remote collaboration.
