The BOYA BY-WM3D is an easy-to-use, digital true-wireless microphone system designed to capture clear, intelligible speech to your iPhone/iPad, DSLR/mirrorless camera, or any smartphone/tablet equipped with a headphone jack. It is a great choice for journalists, YouTube/Instagram creators, TikTok personalities, and vloggers.

Tiny Microphone Yet Powerful on Functions

With no bodypack and no cables, the system provides a true cable-free experience. For demonstrations, presentations, and performances, this gives the user complete freedom of movement. The transmitter's miniature housing allows you to clip it to clothing, slide it into a shirt pocket, place it on a podium, or hold it in your hand. When compared to DSLR and mobile device built-in microphones, this allows you to position the microphone closer to the speaker's mouth, resulting in significantly improved sound quality.

Easy to Use with 4.5 Hours Running Time

The BY-WM3D can be used right out of the box by anyone, regardless of their level of experience. When you remove the microphone from the included charging case, plug it in, and turn it on, it's ready to use, so you can concentrate on creating your content. The system runs on rechargeable batteries and can transmit clear sound for up to 4.5 hours at a distance of up to 20 metres.

Using in Different Environment

Everything you'll need to record crystal-clear speech in any situation is included with the BY-WM 3D. In addition to the clip-on transmitter with built-in microphone and the plug-in receiver with three types of interchangeable audio adapters, you get a foam windscreen and a furry windshield to reduce wind noise when working outdoors. A charging case is included to recharge the batteries and transport your equipment safely.
