I just had this problem recently where I listen to music and I will also hear it on the phone speaker. I already did the Factory Reset for my headphones.

Do all apps do this or just specific ones ?

Thanks Bluetooth Doctor! Actually I found out it was the Facebook Messenger that caused the problem. When I restarted the phone and the device, the problem still persisted so I saw that you need to force stop a few apps to see. When I force stopped Youtube, Netflix, Facebook, it didnt do it. But after force stopping Messenger, the bluetooth headphones worked fine.
