BOYA BY-WM4 PRO K1 Wireless Microphone System - Video, Podcast, Journalism

BOYA BY-WM4 PRO K1 Wireless Microphone System arrives as a compact and affordable solution for video, podcasting and journalism, offering reliable wireless audio capture with a 60 m range.

This BY-WM4 PRO K1 kit includes a lavalier microphone and a bodypack transmitter paired with a bodypack receiver, both measuring 45 x 35 x 70 mm and weighing only 47 g, so the whole system stays unobtrusive during shoots and interviews.

Designed for simple connectivity, the lavalier plugs in via a 3.5 mm jack and operates in the 2405–2478 MHz band using GFSK modulation. The system delivers a frequency response on the receivers from 35 to 14,000 Hz, with a signal-to-noise ratio of 84 dB and total harmonic distortion of just 0.05% for clear, natural sound.

Power is supplied by two AAA batteries (1.5 V each) for both transmitter and receiver, and the receiver’s maximum power consumption is 70 mA, with RF output at 3 mW to balance range and battery life. The BY-WM4 PRO K1 supports two channels, making it flexible for different setups.

The kit comes with a carrying case for secure transport and protection, and ships with one microphone, one transmitter and one receiver—everything needed to start recording quickly in the field.

Typical use cases include run-and-gun interviews, on-camera reporting, single-host podcasts, and content creation for social media where mobility and discreet miking are important.

Key selling points are its light weight and compact dimensions, long 60 m wireless range for most on-set conditions, low distortion and high SNR for clean audio, plus the convenience of AAA battery power and a protective carrying case.
