The BOYA BY-M1DM Dual Omnidirectional Lavalier Microphone is the go-to wired mic solution for content creators, journalists, and videographers who need to record two voices simultaneously on a single device. With two condenser lav mics sharing one 3.5mm TRRS connector, it plugs directly into your smartphone, DSLR, mirrorless camera, camcorder, or computer — no adapter juggling required.
Each mic captures audio on its own discrete channel, giving you full control over individual levels in post-production, while the impressive 74 dB signal-to-noise ratio ensures clean, professional-grade recordings with minimal background hiss. Power is drawn automatically from your smartphone, and an included LR44 battery keeps you rolling when shooting with a camera.
Key features

Frequently asked questions
Can the BOYA BY-M1DM be used with both smartphones and DSLR cameras?
Yes. The BY-M1DM features a 3.5mm TRRS connector that plugs directly into smartphones for plug-in power, and it includes an LR44 battery to provide the power needed when connecting to a DSLR, mirrorless camera, or camcorder.
Does each microphone record to a separate audio track?
Yes. Each of the two lavalier mics is routed to its own discrete channel, allowing you to adjust the volume levels of each speaker independently in your video or audio editing software.
How does the omnidirectional pickup pattern help during interviews?
The omnidirectional pattern picks up sound equally from all directions, so if a speaker turns their head or shifts position, the mic continues to capture their voice at a consistent level — reducing the risk of sudden dips in audio quality during a live interview.
