SMALLRIG S70 Wireless Lavalier Microphone Kit

The SMALLRIG S70 is a wireless lavalier microphone kit with two transmitters and USB-C and 3.5 mm receivers. Its stated compatibility covers phones, cameras, tablets and computers, while the claimed 40-hour total runtime depends on the charging case.

At a glance

Two transmitters and two receivers are stated in the title, including one USB-C receiver and one 3.5 mm receiver in the contents list.
The listing claims 8 hours of use per charge and 40 hours total with the charging case. Treat these as manufacturer claims rather than measured results.
Nine silicone covers and two furry windscreens are listed, alongside three noise-reduction modes, five gain levels and three mixing options.
USB-C and 3.5 mm receiver options support a range of listed phones and devices, but compatibility depends on the device's ports and interface.

Pros and cons

Pros

A two-transmitter kit can suit recording two people, with separate USB-C and 3.5 mm receiver options listed.
The contents list includes a charging case, nine silicone covers, two furry windscreens, cables and a carry bag.
The claimed 8-hour per-charge runtime and 40-hour case-assisted total offer useful planning figures for longer recording days.

Cons

Using the stated 40-hour total runtime depends on the charging case, and the listing gives no separate case recharge-time detail.

What to know before buying

The listing’s claimed 40-hour total runtime appears alongside a separate title for a two-transmitter kit, but another included related kit is not evidence about this model’s runtime. Confirm the selected product’s exact package and check device-port compatibility before buying. The listed USB connectivity label does not itself explain the wireless link.

Noise cancellation and wireless connectivity receive mixed reports, including some pairing concerns. That matters for interviews and on-location recording: the listing offers noise-reduction modes and multiple receiver types, but neither guarantees consistent results with every device or environment.

Wireless connectivity feedback is mixed, including reports of pairing problems.
