Overview
The SmallRig S70-C2 2-Person Wireless Microphone System is built for recording two-person vlogs or interviews on USB-C mobile devices. It pairs two ultracompact clip-on transmitters, each with a built-in microphone, with a dual-channel plug-in receiver that connects straight into your phone's USB-C port. An advanced audio chip, adjustable noise reduction and gain, and multiple EQ presets make it a practical choice for content creators who need reliable two-person audio on the go.
48 kHz/24-Bit Audio Recording
An ATS3031 audio chip supports 48 kHz 24-bit recording with an auto-limiter, along with nine preset EQ modes covering general, rich, bright, male, female, singing, guitar, violin and ambient sound sources.
Adjustable Noise Reduction and Gain
- Three-level noise reduction to cut background sound.
- Five-level gain control to match input volume.
- Three mixing modes for mono, stereo and safety track recording.
USB-C Plug-In Receiver
The dual-channel receiver plugs directly into your phone's USB-C port and runs on the device's own power, with a pass-through port that charges your phone at the same time.
8-Hour Transmitters with Charging Case
Each clip-on transmitter runs for up to 8 hours on its built-in battery, and the included charging case extends total runtime to over 40 hours.
