How to use your phone as a microphone for a Bluetooth speaker

You don't need a dedicated wireless microphone to be heard through a Bluetooth speaker. With RemoteMic your Android phone becomes the mic, and your voice plays live through any speaker, soundbar or headset you've paired — no cables, no extra hardware.

What you need

• An Android phone (Android 11 or newer) with RemoteMic installed.
• A Bluetooth speaker, soundbar or headset.

Step by step

1. Pair the speaker first. Open Android's Bluetooth settings and connect your speaker or headset as you normally would. RemoteMic uses whatever audio device Android is connected to.
2. Open RemoteMic and choose Bluetooth output. On the Home screen, switch the output from Webstream to Bluetooth. The app shows which device is in use.
3. Tap the mic to go live. Speak into the phone and your voice comes out of the speaker in real time. Adjust the gain if you want more or less level.

Avoiding feedback

Because the phone is the microphone and the speaker is the output, keep them apart. A speaker placed right next to the phone — or aimed at it at high volume — can ring or squeal, exactly like any PA system. Keep a step or two of distance and a sensible volume and you're fine. For a completely feedback-free setup with a group, have each listener use their own headphones instead of a shared speaker.

When this is handy

• A handheld mic for a small room — feed a portable Bluetooth PA without renting gear.
• Assistive listening — route your voice straight into a hard-of-hearing guest's Bluetooth headphones.
• Practice and monitoring — hear yourself through headphones while you rehearse.

No Bluetooth speaker? Stream to a browser instead

RemoteMic can also stream to any browser on the same Wi-Fi, or create its own private hotspot when there's no network at all — so a whole group can listen on their own phones and headphones. See how RemoteMic works for the full picture.
