SmallRig 5715 S70 Wireless Microphone with Multi-Device Compatibility (Black)

SmallRig 5715 S70 Wireless Microphone (Black) — semi-concealed nitinol memory-alloy clip for near-invisible on-camera audio

The SmallRig 5715 S70 targets content creators and streamers who use cameras or smartphones. It suits live streaming, daily vlogging, short video production, travel filming, and interviews. The system balances discreet on-camera presence with high-quality audio features for a range of recording scenarios.

Design and attachment

The S70 uses a semi-concealed design with a nitinol memory-alloy clip structure. The exposed components measure only 8.8 × 29mm, and the entire unit weighs 8.6g. When clipped to a collar, it remains nearly invisible and does not affect clothing or appearance, making it suitable for shoots where a clean visual is important.

Receivers and connectivity

The kit includes RX receivers with USB-C and 3.5mm connectors. This design ensures compatibility with most mainstream Android smartphones and cameras. In addition, the system supports computers with UAC-compatible ports and certain USB-C cameras from Insta360 and DJI Osmo series, as listed in the compatibility section.

Audio performance and controls

The S70 leverages an ATS3031 chip and supports high-fidelity 48 kHz/24-bit audio recording. It offers three noise reduction modes, five levels of gain adjustment, and three mixing modes so you can adapt to different environments and capture clear sound. An auto limiter prevents clipping and helps deliver consistent, distortion-free recordings.

Battery life and workflow

Each transmitter provides up to 8 hours of continuous use on a single charge. When you use the included charging case, total battery life extends to over 40 hours, which is sufficient for two to three days of typical operation without needing to recharge the case.

Sound tuning

Grammy-winning sound engineer Luca Bignardi tuned the system. The microphone provides nine preset EQs designed to enhance vocal clarity and purity across different voice types and recording conditions.
