App snapshot
Mic Speaker is a free multimedia utility for iOS created by Seong Eon Kim. It enables your iPhone to route live microphone audio to a chosen output device, turning the phone into a portable loudspeaker, assistive listening aid, or presentation mic.
Choosing where sound plays
Features that control output let you pick the target speaker for the microphone signal. Supported output types include:
- Wired headset
- Earbuds
- Bluetooth speaker
- Bluetooth headset
Switching between these targets is simple, so you can route mic audio to whichever device suits the situation.
Using streaming services and singing along
The app supports playing microphone sound while you stream music or videos, so you can sing along to tracks from services like YouTube. That makes it useful for quick practice sessions, impromptu karaoke, or rehearsing with backing tracks.
Run in the background
Mic Speaker can continue outputting microphone audio even when other apps are in use. This background operation lets you multitask on your iPhone while the mic feed remains active.
Typical ways to use it
Common use cases include:
- Assisting someone with hearing needs during one-on-one conversations
- Amplifying your voice for small presentations or announcements
- Using the phone as a handheld megaphone for outdoor or crowded settings
- Practicing vocals with a music track playing from another app
