The BOYA BY-WM3U is an easy-to-use, digital true-wireless microphone system designed to capture clear, intelligible speech to your Android phone/tablet, DSLR/mirrorless camera, or any smartphone/tablet equipped with a headphone jack. It's ideal for journalists, YouTube/Instagram creators, TikTok personalities, and vloggers.

Tiny Microphone Yet Powerful on Functions

The system provides a true, cable-free experience with no bodypack and no cables required. This enables the user to experience complete freedom of movement for demonstrations, presentations, and performances. You are able to clip the transmitter to clothing, slide it into a shirt pocket, place it on a podium, or hold it in your hand thanks to the transmitter's miniature housing. When compared to the built-in mics on DSLRs and mobile devices, this allows you to position the microphone close to the speaker's mouth, resulting in significantly improved sound quality.

Easy to Use with 4.5 Hours Running Time

Anyone, regardless of their level of experience, can operate the BY-WM3U right out of the box. The microphone is set and ready once it's removed from the included charging case, plugged in, and powered on, so you can focus on creating your content. On rechargeable batteries, the system provides reliable transmission with clear sound at a distance of up to 20m for up to 4.5 hours.

Using in Different Environment

The BY-WM3U comes with everything you'll need to record crystal-clear speech in any setting. You also get a foam windscreen and a furry windshield to reduce wind noise when working outdoors, in addition to the clip-on transmitter with built-in microphone and the plug-in receiver with three types of interchangeable audio adapters. To recharge the batteries and transport your equipment safely, a charging case is included.
