SmallRig S70 Multi-Device Kit – Discreet Mics, Phone and Camera

The S70 Multi-Device Kit (6526) is a two-person wireless microphone system for creators who switch between a phone and a camera. It ships with a USB-C receiver for Android phones, tablets and computers and a 3.5 mm camera receiver, plus two nearly invisible transmitters. At Soundium it is the version of the S70 built for mixed phone and camera shoots.

Key Features

• Semi-concealed 8.6 g transmitters: A memory-alloy clip leaves just 8.8 × 29 mm visible on a collar.
• Two receivers in the box: USB-C for phones and computers, 3.5 mm for cameras, so one kit covers both.
• 48 kHz / 24-bit audio: 70 dB signal-to-noise ratio and 120 dB max SPL with an auto limiter against clipping.
• Tuned presets: Nine EQ presets by Grammy-winning engineer Luca Bignardi, three noise reduction levels and five gain steps.
• All-day battery: About 8 hours per charge and over 40 hours in total with the charging case.
• Nine colour covers: Soft silicone covers match the mic to clothing or keep it discreet.

Customer Benefits

One kit handles the phone vlog in the morning and the camera interview in the afternoon, without buying a second receiver. Mono, stereo and safety-track modes give a backup recording when levels spike, and the charging case keeps everything powered and in one place between takes. Because the transmitters are so small and colour-matched, the S70 stays out of the frame for weddings, interviews and talking-head content where visible mics would distract.
