The Boya BY-WM4 PRO-K2 is a compact entry-level wireless system with two lavalier microphones that offers an easy-to-use, cost-effective, and all-inclusive solution for recording two subjects to your camera, camcorder, or mobile device. The system delivers improved sound quality over the built-in mics on cameras and mobile devices, to supply clear, intelligible speech for interviewers, journalists, YouTube/Instagram creators, TikTok personalities, vloggers, and more.
The package includes two omnidirectional lavalier mics and two bodypack transmitters with belt clips that allow your subjects to move around hands-free in front of the camera for interviews, demonstrations, presentations, and performances. The compact, dual-channel receiver offers a 200′ line-of-sight maximum operating range and includes an attachment clip and a camera shoe mount for flexible mounting options.
Connecting cables for both your camera and smartphone are included, while the 3.5mm jack on the receiver lets you plug in headphones for monitoring while you’re working on set. The transmitters and receiver are both powered by two AAA batteries for up to 11.5 hours and arrive prepaired at the factory—just power up, plug the receiver into your camera or phone, and you’re ready to go.
