Mono Bluetooth Router App is a free Android application developed by codococo. It is a useful utility and tool that allows users to listen to music through a Bluetooth headset that does not support the A2DP profile. This app is particularly useful for people who have older headsets that do not support stereo audio streaming.

The app is simple to use and does only one thing – it routes audio to your mono Bluetooth headset. When you receive an incoming or outgoing call, the audio routing is automatically canceled and then started again when the call is terminated. The app does not have any other features besides mono routing, and the developer has confirmed that no other features will be supported in the future.
