Live Mic to Bluetooth Speaker

Turn your phone into a wireless microphone.

"Mic to BT Speaker" streams your voice live from your phone's microphone to
any Bluetooth speaker in real time — with minimal latency. No PA system, no
extra hardware. Just your phone, any Bluetooth speaker, and this app.

HOW IT WORKS
