SmallRig S70-C1 Wireless Microphone System for USB-C Mobile Devices (2.4 GHz, Black)

Overview

The SmallRig S70-C1 Wireless Microphone System for USB-C Mobile Devices (2.4 GHz, Black) is a compact wireless audio solution designed for solo content creators filming vlogs and interviews directly on a compatible mobile device. The kit pairs one clip-on transmitter with a built-in microphone and a dual-channel USB-C plug-in receiver, giving you clean, broadcast-ready audio without a separate recorder. An advanced audio chip captures 48 kHz/24-bit sound with automatic level limiting, while nine onboard EQ presets, three-level noise reduction, and five-level gain control let you dial in the right tone for any voice or environment. A built-in battery powers the transmitter for up to 8 hours, and the included charging case extends that to 20 hours in total, making it a reliable everyday kit for run-and-gun content creation.

Clean Audio Capture and Processing

An ATS3031 audio chip records at 48 kHz/24-bit and applies an automatic limiter to prevent clipping. Three noise reduction levels, five gain levels, and nine EQ presets, including general, rich, bright, male, female, singing, guitar, violin, and ambient, let you tailor the sound to your voice and location. Three mixing modes support mono, stereo, and safety-track recording for extra flexibility in post.

USB-C Receiver with Pass-Through Charging

The dual-channel receiver plugs directly into your device's USB-C port and draws plug-in power, with a pass-through port that charges your phone or tablet at the same time so recording never has to interrupt your battery life.

All-Day Battery with Charging Case

The transmitter runs for up to 8 hours on its built-in battery. Slot it into the included charging case between takes and total system runtime extends to 20 hours, making the kit easy to carry through a full day of shooting.
