A free app for Android, by Sarva Info.

With Audio Switch-Disable Headphone, you can turn off your headset while listening to music. It’s the best way to enjoy your phone’s audio without losing the sound.

It works with any Android phone.

This application is useful in situations where the built-in speakers or headphones are not suitable or where you need to use a different device. For example, if you’re using a tablet, you can still listen to music through the built-in speakers or headphones. But if you’re using a smartphone, you’ll need to use the Audio Switch-Disable Headphone app to play your music.

This app lets you easily play all your audio through your built-in smartphone speakers bypassing the connected headphones just with the flick of a switch.

It works for all Android devices.
