"Disable/Enable Absolute Volume (Bluetooth): Separates Your Phone’s Volume From Your Bluetooth Device
Have you ever faced a sudden volume increase on your Bluetooth headphones and had to pull them out of your ears? Yes, this happens frequently, especially if you use smartphones at high volumes. Even though the latest buds adopt volumes, there are still some instances where buds can register accidentally higher volumes.
Fortunately, there is a developer setting that you can enable to keep your Bluetooth device volume separate from your phone volume. When you enable the disable absolute volume Bluetooth settings on your phone, your phone and Bluetooth device will have their own separate volume controls.
While in some cases, absolute volume is enabled by default, however, if you want the convenience of controlling both your phone and device volume control using the same volume control, you can enable it so that it brings single volume for both your phone and device.
Also, disabling or enabling volume is not available on all smartphones, including my current OnePlus 13S. However, if you’re using a Samsung or other smartphone, you can enable it or disable it from the settings.
To do this, go to settings and the developer options, and under Bluetooth and networking, enable/disable the option that says Disable Absolute volume settings. Also, if you still don’t see the option, first ensure you have enabled and connected Bluetooth devices."
