BOYA BY-M1 PRO II Condenser Lavalier Lapel Microphone for iPhone Android PC Computer Smartphone DSLR Streaming Youtube Recording

BOYA BY-M1 Pro II is the upgraded, second-generation Pro version of BOYA’s clip-on lavalier series. Designed for content creators, vloggers, interviewers, and educators, it provides 360-degree omnidirectional sound pickup for smartphones, DSLR/mirrorless cameras, tablets, laptops, and audio recorders.

Unlike older generations, the BY-M1 Pro II operates completely battery-free (Plug-and-Play) across all devices. It incorporates specialized features such as a -10dB pad attenuation switch (to prevent audio distortion/clipping in loud environments) and a 3.5mm headphone monitoring jack on the inline control module.

Feature Detail

• 100% Battery-Free Plug & Play: Connects directly without requiring LR44 button-cell batteries, drawing power straight from the host device in both Camera and Smartphone modes.

• -10dB Attenuation Pad Switch: An inline switch that instantly drops the input gain by 10 dB to prevent digital clipping when recording loud voices, instruments, or noisy environments.

• 3.5mm Real-Time / Playback Monitoring Jack: Features a built-in 3.5mm headphone jack on the control block, allowing you to plug in wired headphones to check audio quality while in Smartphone mode.

• Universal Camera / Smartphone Mode Switch: An inline physical switch that toggles output circuit routing to match standard smartphone TRRS jacks or camera/recorder TRS jacks.

• 6-Meter (19.7ft) Shielded Cable: Generous cable length allows wide video framing, presentation movements, or camera separation without signal interference.

3. Headphone Monitoring: Provides an easy way to check audio playback/monitoring directly on mobile devices without unplugging the mic.

4. Improved Low-Noise Capsule: Higher Signal-to-Noise Ratio (>78 dB) delivers a lower noise floor and clearer voice reproduction compared to standard budget lavaliers
