Is there any way to modify the phone's maximum output volume under Bluetooth to be able to tune to a smaller volume of the Bluetooth headset to reduce noise?

On my BT headset (LG HBS73) the adjustments the volume on the phone is independent of the adjustment on the headset. I realised that the chance of clipping is rather high if I go to maximum phone volume and adjust the volume on the headset. So I came to the conclusion that the signal level on the phone is already close to or even above distortion level. Hence your aim is probably pointless as it will probably end up in clipping and distortion.

Neverthelesess you could do some research an pulse audio, I'd bet there are config options to raise the output level. Maybe a search on pulse audio in this forum helps.

My example is with my Bose AE2w headphones connected via BT to my Jolla1, as per my personal notes


Set volume to ZERO
    `pacmd set-sink-volume 10 0` (0%)

Set volume to MAX    
    `pacmd set-sink-volume 10 65536`  (100%) (default)
    `pacmd set-sink-volume 10 98304`  (150%)
    `pacmd set-sink-volume 10 131072` (200%)

You can discover which INDEX number represents the appropriate audio sink, for me the INDEX is "10" for Bluetooth:
