My iPhone 7 was playing music over my bluetooth headphones fine up until a few days ago. Now all music just plays through the iPhone speakers instead.
I looked in the Settings - Bluetooth and the headphones display as "Connected".
This is not a new headset; it was working correctly up until just a few days ago.
When I power up the headset it gives me the same message it usually does when successfully connected to the iPhone, "Power On - Connected".
Is there a setting somewhere that overrides where the audio outputs to?
