Boya BY-WM3U USB-C wireless microphone

Boya BY-WM3U - USB Type-C wireless microphone system for smartphones

The Boya BY-WM3 is a wireless microphone system using 2.4 GHz transmission technology. The package includes a Lightning-connected receiver and a transmitter with built-in microphone. Both of these are compact in size and lightweight.

The BY-WM3U is therefore particularly suitable for use with Android smartphones thanks to its USB-C connection, but the included interchangeable connector heads also allow the receiver to be fitted with TRS and TRRS connectors. The three different connection options maximise the compatibility of the device with different storage devices.

Thanks to the built-in omni-directional microphone in the compact transmitter unit, the system is virtually plug and play. Simply connect the transmitter and receiver together, plug the receiver into the recording device and you're ready to start recording.

The product also comes with a charging dock, which also serves as a handy case for your devices. In addition to charging, the dock can also be used to pair the transmitter and receiver. After a full charge, the transmitter battery lasts for about 4.5h and the receiver for about 8h.
