Why people use Bluetooth Mic

One job: your phone becomes the mic, any Bluetooth speaker becomes the PA. No mixer, no receiver, no cables.

Any Bluetooth speaker

Works with speakers, soundbars, headsets and car audio — whatever you can pair.

Live voice monitoring

Real-time feedback so you hear yourself as you speak, with minimal delay.

Adjustable gain

Dial the mic level up or down for the room, so you're clear without clipping.

One-tap connect

Pair once and reconnect automatically — no reconfiguring every time.

Works offline

No account and no internet needed; set up and go anywhere.

Nothing recorded

Audio is passed through live and stays on your device — no recordings stored.

How it works

From phone to PA system in under a minute.

  1. Pair your speaker

    Connect your Bluetooth speaker, soundbar or car audio to your iPhone as normal.

  2. Open the app and connect

    Tap to route the mic to your speaker, and set the gain for the room.

    Your voice plays live through the speaker — announcements, karaoke, teaching, done.
