SmallRig S70-C1 Wireless Microphone with USB-C Adapter for Phones (Black) 6546 is engineered for content creators and streamers using smartphones. It is the ideal audio solution for live streaming, daily vlogging, short-form video, travel filming, and interviews.

Its semi-concealed design features a nitinol memory-alloy clip. The visible portion measures just 8.8 x 29mm (0.3 x 1.1in), and the entire unit weighs a mere 8.6g (0.3oz). When clipped to a collar, it remains nearly invisible and unobtrusive—without affecting clothing or appearance—making it perfect for users who demand both premium audio and a clean on-camera aesthetic.

The system includes an RX receiver with a USB-C connector, ensuring broad compatibility with most mainstream Android smartphones. Powered by an ATS3031 chip, it delivers high-fidelity 48 kHz/24-bit audio. With three noise reduction modes, three levels of gain adjustment, and two mixing modes, it adapts seamlessly to any recording environment. A built-in auto limiter prevents clipping for consistently clear, distortion-free sound.

The microphone provides up to 8 hours of continuous use on a single charge. Paired with its charging case, the total system runtime extends to over 20 hours—enough for one to two full days of operation without recharging.

Expertly tuned by Grammy-winning sound engineer Luca Bignardi, the nine preset EQs enhance vocal clarity and purity across various voice types and recording conditions.

The package includes nine colored protective covers for flexible styling and personalization.
Each cover measures a compact 31.6 x 10.8 x 12.7 mm (1.2 x 0.4 x 0.5 in), ensuring a discreet, low-profile appearance.

Made from soft 60° silicone, the covers are skin-friendly, gentle on clothing, and feature a simple design for quick, tool-free installation.
