The Saramonic UwMic9 SP-RX9+TX9 is a portable UHF wireless microphone system that was designed to be used with an iPhone or Android smartphone, as well as cameras and other devices.

Multiple output cables are included: Lightning for Apple devices, USB-C for Android, and analog 3.5 mm for cameras and other devices. A smartphone holder is built into the receiver, and a removable handgrip stabilizes your mobile videos. A shoe-mount at the top lets you to attach important accessories, such as video lights and shotgun microphones.
The included SP-RX9 dual-channel wireless receiver can also be used as an audio mixer. You can plug two microphones directly into it and connect it to your smartphone or camera of choice.

The included beltpack transmitter runs on AA batteries, and the receiver is powered by an internal Lithium-ion battery, which can easily be charged via its USB-C port with an included cable. The USB-C port is also compatible with external battery power packs, so you can keep it powered in the field. The included handgrip screws into a 1/4-20 tap at the base, and you can use this mounting point to attach the SP-RX9 to a DSLR, mirrorless or video camera. The settings of the SP-RX9 let you put it into “camera” mode, which adjust the output to work perfectly with cameras.
The power button on the TX9 beltpack transmitter can easily be set to “locked” to prevent it from accidentally being turned off when in use. If the person wearing the clip-on lavalier microphone needs privacy, a quick push of a button turns on a muting feature, and a flashing red LED reminds you to unmute it afterward. The system offers an impressive operating range of up to 330-feet (100m), and the included SR-M1 lavalier microphone provides amazing sound quality.
