The BOYA OMIC-U Wireless Microphone System . The system includes two clip-on transmitters with built-in omnidirectional microphones and a dual-channel, plug-in receiver with a USB-C connector, which inserts into your compatible device. Attach the transmitters to your talent’s lapel and record audio for social media. All of the components can communicate from up to 164′ away. A single button on both transmitters toggles intelligent noise cancellation technology to minimize background noise for clearer audio capture. The receiver runs on plug-in power from your device. Built-in rechargeable batteries power the transmitters for up to 5 hours at a time. The included charging case recharges the components to expand their battery life to up to 15 hours.
