Bluetooth volumes have been haunted ever since 4.4. Hell... plugging in the charger when I am on my vehicle's bluetooth changes the volume.
Hoping this finally get this fixed in 4.4.3, but until then, I have found a number of tricks.
1.) There is a sweet spot on the volume scale (around 70%) that is best to leave it at.
2.) I haven't had to restart my phone... usually just cycling BT off and on again restores original volume. Sometimes even starting/stopping media playback fixes it.
