Official UK distributors of Studio Six Digital microphones for Apple iOS, including iPad and iPhone, and now other devices with USB connections.

We started selling Studio Six Digital products back in 2014 when they released the original iTestMic with the 30-pin connector.  Since then we've sold many units of the popular iTestMic2 and the Class-1 ready iPrecisionMic for turning iPhones and iPads running the AudioTools app into a fully functioning sound level meters.

With the introduction of the USB-C connected uTestMic and uPrecisionMic, now any device can become a portable sound level meter.
