SmallRig S70-C2 Wireless Microphone with USB-C Adapter for Phones (Black) 5717

It is ideal for a wide range of scenarios, including live streaming, daily vlogging, short video production, travel filming, and interviews.

Featuring a semi-concealed design with a nitinol memory-alloy clip structure, the exposed components measure only 8.8 × 29mm, and the entire unit weighs a mere 8.6g. When clipped to a collar, it remains nearly invisible and unnoticeable—without affecting clothing or appearance—making it an excellent choice for users who demand both high audio quality and a clean on-camera presence.

The system includes smartphone RX receivers with USB-C connectors, ensuring broad compatibility with most mainstream Android smartphones.

Equipped with an ATS3031 chip, it supports high-fidelity 48 kHz/24-bit audio recording. With three levels of noise reduction, three gain settings, and two mixing modes, it easily adapts to diverse recording scenarios. An auto limiter prevents clipping, ensuring consistently clear, distortion-free sound.

The microphone offers up to 8 hours of continuous use on a single charge, and when paired with the charging case, the total battery life extends to over 40 hours—sufficient for 2 to 3 days of operation without needing to recharge.
