Looking comparable in size to an Apple AirTag, the Insta360 Mic Air is one of the smallest and lightest wireless mics now available while still offering up to 10 hours of battery life. The Insta360 Mic Air is currently available through the company’s online store and retailers like Amazon for $49.99 for the microphone by itself, or as part of a $69.99 bundle that includes a USB-C receiver needed to connect the mic wirelessly to smartphones and Insta360’s stabilized gimbals. An optional USB-C receiver, that includes a charging passthrough port, is needed to wirelessly connect the Mic Air to smartphones and other devices.

Although Bluetooth connectivity is included, the optional USB-C wireless receiver is needed to use the Mic Air with smartphones, which also means you’ll potentially need a cumbersome adapter dongle to use it with older iPhones that still have a lightning port.
