The SmallRig S70-C2 is a USB-C wireless microphone system designed for creators and streamers using Android phones. It supports a range of recording situations, from livestreaming and everyday vlogs to short-form video production, travel filming, and interviews.
A semi-concealed design and nitinol memory-alloy clip help keep the microphone discreet on camera. The exposed portion measures just 8.8 × 29mm (0.3 × 1.1in), allowing it to sit unobtrusively on a collar without interfering with clothing or drawing attention away from the wearer.
An ATS3031 chip supports 24-bit/48kHz recording for clean, detailed sound. The audio specifications include a 70dB signal-to-noise ratio, a maximum sound pressure level of 120dB, and a 20Hz-20kHz frequency response.
- - Three noise-reduction levels help adapt processing to different recording environments.
- Adjustable gain and Mono/Stereo mixing provide control over recording levels and the output mix.
- An automatic limiter suppresses sudden peaks to help prevent clipping and distortion.
Grammy-winning sound engineer Luca Bignardi tuned the system's nine EQ presets to enhance vocal clarity across different voices and recording conditions. The available presets are General, Rich, Bright, Male, Female, Singing, Guitar, Violin, and Ambient, providing choices for speech, music, and environmental recordings.
A transmitter provides up to 8 hours of continuous use on one charge. With the charging case, total battery life extends beyond 40 hours—enough for 2 to 3 days of operation without needing to recharge the system.
- - USB-C connectivity supports Android smartphones and tablets with USB-C ports.
- Camera compatibility includes select Insta360 models and select DJI Osmo-series models equipped with USB-C ports.
A rugged ABS+PC body is designed for use on location. The compact charging case and carrying bag provide portable storage, while the case's travel-oriented design emphasizes convenient transport and organization.
