Inrico B-01 Bluetooth microphone for IOS

Bluetooth Speaker Microphone for Wireless Connection with iOS Apple Smartphones
We recommend using the B01 exclusively with the Zello app. Most other apps are largely incompatible with the B01.
Easy pairing: Simply turn it on, search for it with your Bluetooth-enabled iOS smartphone, and connect.
Once the microphone is connected to your device, it can be used immediately.
You can also connect an external earphone via the 3.5 mm audio jack.
This affordable and compact microphone offers greater mobility than wired audio accessories.
The microphone features a powerful battery and can be charged in approximately 2.5 hours using the included USB cable and AC adapter.
A belt clip is also included in the package.
