BY-WM3T2 series is a mini 2.4GHz wireless microphone system that provides high-quality sound for live streaming, vlogging, course recording, and other audio-capturing applications. The BY-WM3T2-M2 is designed for cameras and devices with a 3.5mm jackpot. Including the 2 transmitters, it can record two sound sources at the same time. Tiny & Lightweight Wireless Mic BY-WM3T2 series is impossibly compact and lightweight, and it’s easy to get started as long as you plug the receiver into the device. The combined weight of the TX and RX is no more than 20g, making them very portable. Because of its ultra-compact size and super lightweight, the transmitter won’t tug at your collar when you clip it.
