The Hollyland Lark 150 Microphone System is a wireless dual-mic system that provides clear sound under any conditions. It is extensively used by vloggers, videographers, and mobile journalists. The lightweight, compact digital wireless microphone features two ultra-compact, clip-on microphone transmitters and a receiver that facilitates cost-effective and seamless recording of two subjects simultaneously to your audio recorder, camera, or camcorder. Boasting an ultracompact construction with the world's smallest and lightest transmitters, Lark 150 features an anti-vibration design and smart frequency selection using FHSS technology to give a crisp, clear signal using 2.4 GHz bandwidth. The receiver features volume buttons, a headphone monitoring output, a line output, and a display that shows the connection and battery status of all three units. It comes in a convenient, portable charging case, where all its three units are charged seamlessly.
