The BOYA BY-WM4 PRO K2 is a dual-channel digital wireless lavalier microphone system designed for creators who need to record two people at the same time. It is suitable for interviews, YouTube videos, TikTok content, vlogging, livestreaming, presentations, journalism, social media videos and other content where clear spoken audio matters.
The system uses a 2.4GHz digital wireless connection and comes with two bodypack transmitters, two omnidirectional lavalier microphones and one dual-channel receiver. This allows two speakers to be recorded through a single receiver connected to a compatible camera, smartphone, camcorder, tablet or computer.
With an operating range of up to 60 metres in unobstructed conditions, the BY-WM4 PRO K2 gives creators freedom to move around while recording. The system is also compact enough for portable content production and includes a carrying case for easier storage and transport.
If you're looking for a practical wireless microphone for interviews, TikTok, YouTube or two-person videos in Kenya, the BOYA BY-WM4 PRO K2 provides a straightforward wireless audio setup without requiring a complicated professional audio system.
The BY-WM4 PRO K2 is designed to capture audio from two people simultaneously. It includes two transmitters and two lavalier microphones connected to a single dual-channel receiver.
This makes it particularly useful for:
The system operates on the 2.4GHz digital wireless band, using GFSK modulation. This provides a cable-free connection between the transmitters and receiver while keeping the setup relatively simple.
BOYA specifies an operating range of up to 60 metres / 197 feet without obstacles. Actual range can vary depending on walls, interference, people and the recording environment.
The included lavalier microphones use an omnidirectional pickup pattern, allowing them to capture speech without requiring the speaker to stay perfectly positioned in front of the microphone.
The K2 package is built specifically for recording two subjects. Each person can wear their own transmitter and lavalier microphone while both signals are received by the same receiver.
The receiver includes a 3.5mm headphone output, allowing compatible setups to monitor the incoming audio while recording.
The BY-WM4 PRO system is designed to work with smartphones, tablets, DSLR/mirrorless cameras, consumer camcorders and PCs when the correct compatible cable or connection is used.
The transmitter and receiver units use AAA batteries, making it possible to replace batteries rather than depending entirely on built-in rechargeable batteries. The K2 system is rated for approximately 6 hours of operation in some specifications, depending on usage and conditions.
The transmitter and receiver are compact bodypack-style units, making the system convenient for creators who move between different filming locations.
