Audio Output Switcher & Tester

Audio Output Switcher & Tester lets you choose where your phone plays call and voice audio: the loudspeaker, wired headphones or a paired Bluetooth device.

It also offers a speaker mode for when the phone acts as if headphones are still plugged in. Turn on the switch, pick speaker mode, and check the speaker, the earpiece and your headphones with a short listening test.

What you can do

• Route call and voice audio to the phone speaker, to headphones on the 3.5mm or USB jack, or to a Bluetooth device

• Speaker mode for call and voice audio when the phone wrongly thinks headphones are plugged in

• See the headset status at a glance: speaker mode, earphone connected or Bluetooth active

• Test the loudspeaker, the earpiece and your headphones: listen to spoken numbers and type them in

• Use the app in 10 languages, including Arabic, German, French, Spanish and Japanese

How it works

Open Change Mode, turn on the master switch and choose Speaker, Bluetooth or Headphone. Sound Test is separate: it checks the phone's loudspeaker, earpiece and wired headphones themselves.

Good to know

Audio Switch uses the phone's call audio mode: it changes where call and voice audio plays while the app is running. It does not remove the headphone icon. The app shows ads, and an optional Pro purchase is available.

Choose where call and voice audio plays, and check your speaker, earpiece and headphones one by one.
