Comica Audio BoomX-D UC2 USB C Ultracompact 2-Person Digital Wireless Microphone System for Android Smartphones (2.4 GHz)
Designed for mobile journalists, videographers, and vloggers, the Comica BoomX-D UC2 is an ultracompact, true wireless digital microphone system with two microphones and just one receiver. It offers a complete solution for recording dialogue, interviews, and speech with two people talking simultaneously—directly to an Android smartphone or a USB Type-C device.
The ultralightweight BoomX-D UC2 consists of two ultracompact clip-on transmitters each with its own built-in omnidirectional microphone and a separate lavalier microphone. It also comes with a tiny receiver that mounts on and plugs directly into the USB Type-C port of your phone. To ensure that you are capturing a clean signal, you can monitor your mics via the receiver's 3.5mm headphone output while recording.
The system delivers reliable transmission with a clear sound at a distance up to 164'. The transmitter's built-in rechargeable batteries provide up to 5 hours of operation. Versatile and extremely easy to use with simple controls, the BoomX-D UC2 is well suited for content creators of any experience level.
