Why is my music still playing out loud with my Bluetooth earbuds in?

Is your device set to play out through your Bluetooth earbuds and not through the speaker?

First, re-pair your Bluetooth earbuds to your phone, so that the phone can see that it is an audio device.

Next [If this doesn't work] is to reboot the phone and try again with pairing the Bluetooth earbuds.

If needed, remove [or "forget"] the earbuds in your phone's bluetooth settings, then re-pair them as if they weren't paired before.
