That's easy! Here's what you can do:
1. Turn on the Bluetooth setting on your phone & connect to your Speakers.
2. Launch the JioSaavn app to play a song.
3. On the Music Player page, tap on the Speaker icon (bottom left corner).
4. You should see your Speaker listed there > select it if it's not already selected.
If this doesn't help, please write to us from the JioSaavn app settings using the 'Contact us/Chat with us' option.
