BOYA BY-M1S Lavalier Lapel Microphone for iPhone Mobile Smartphone PC Computer Android DSLR Cameras Youtube Live Streaming Vlog (without battery) 

BOYA BY-M1S is an upgraded, battery-free version of the legendary BY-M1 lavalier microphone. Designed for content creators, vloggers, journalists, and educators, it delivers clear, broadcast-quality audio directly to smartphones, DSLR cameras, camcorders, audio recorders, and computers.

Featuring a redesigned custom condenser capsule, an improved 78 dB signal-to-noise ratio, and plug-and-play device powering, the BY-M1S eliminates the need for LR44 button batteries while offering lower self-noise and improved voice clarity over the original model.

Feature Detail

• Upgraded Custom Capsule: Equipped with an improved omnidirectional condenser element that delivers a flatter frequency response and higher sensitivity for capturing fine vocal nuances.

• 360° Omnidirectional Pickup: Captures natural sound evenly from all directions, preventing volume drops when the speaker moves their head.

• Inline Camera / Smartphone Switch: A simple toggle switch adjusts output resistance to match cameras or mobile devices seamlessly.

• 6-Meter (20ft) Shielded Cable: Provides wide distance flexibility for filming wide shots or presentations without needing noise-inducing extension cables.

Technical Specifications

Why Recommended & Suitable

1. No Battery Hassles: The biggest drawback of the classic BY-M1 was forgetting to replace or turn off the LR44 battery. The BY-M1S eliminates batteries entirely, making it far more reliable for daily work.

2. Cleaner Audio & Lower Noise Floor: With an upgraded 78 dB Signal-to-Noise ratio (compared to 74 dB on older models), it records noticeably clearer voice tracks with less electrical background hiss.

3. Ideal for Beginners & Pros On-the-Go: Its lightweight design, plug-and-play simplicity, and universal switch make it the most cost-effective clip-on microphone for YouTube, online teaching, interviews, and Zoom calls.
