Lesser AudioSwitch for Android

Brief description and purpose

Lesser AudioSwitch is a free utility from developer Roughy that helps you change where your device sends sound. It provides a quick way to move audio between different output devices and can also choose which microphone to use for input. This makes it a useful companion for people who regularly switch between wired and wireless audio gear.

Compatible output types

• Bluetooth headsets and earbuds (wireless)
• USB DACs and external digital-to-analog converters
• Wired headphones using the 3.5 mm jack
• Built-in speakers

User interface and key features

The app has a simple, easy-to-navigate interface that exposes four main output options to toggle between. You can swap audio between wireless and wired devices without juggling system settings, and if multiple outputs are active you can select the one to use. Audiophiles will appreciate explicit support for portable DACs when higher-fidelity playback is desired. Additionally, mic routing can be controlled independently, letting you pick which microphone is detected for voice calls or recordings.

Important compatibility note

Lesser AudioSwitch does not function on Android 11 and later due to changes in the operating system. On newer versions of Android, many of the same routing options are available through the system settings, so you’ll need to use the OS-native controls instead.

Bottom line

If you frequently use several audio peripherals and want a fast, straightforward way to change outputs or isolate a microphone, Lesser AudioSwitch is a handy, no-cost tool — provided you’re on a compatible Android version.
