Works great on iphone 5s and iOS 7
Delivers on what it promises...lets me listen to audio using my Bluetooth headsets that dont support A2DP. All you do is:
1. Open the app
2. Turn A2DP Blocker "On"
3. Under default audio, select "headset+"
4. The app may then ask you to add a song to the playback queue. Go ahead and add one, and it will then start playing in your headset.
5. Pause the track then switch over to any app you want to listen from.
6. Audio should be playing in your mono headset!!
