It's a wireless lavalier microphone system designed for recording audio, especially for content creation, interviews, and presentations where hands-free operation is desired. It uses omnidirectional condenser radio for 360° sound pickup, boasts a lightweight design (each mic weighs only 8g), and offers features like 48kHz/24bit audio format, 70dB signal-to-noise ratio, and a long wireless transmission range. The microphones charge within the included storage case, which also displays the battery level digitally, and the system offers up to 20 hours of battery life with Type-C direct charging.
