Does not work for me – Volume Master - Dial in the sound of your music player with a control booster Review

I was hoping this app would solve the problem I have with my iPhone and Bluetooth headphones. The lowest volume setting is too quiet and if I go up one increment with the either buttons on my iPhone, the buttons on my headphones, the volume slider in Music, or the volume slider in Control Center then the volume is too loud. I tried using this app and set the increment to .1 and still am unable to achieve a volume setting between too soft or too loud.
