Volume up button not working.

I have recently dropped my bluetooth headset and damaged volume up button. There is no way i can increase the volume of the headphones itself. Volume controls from connected devices don’t make any difference. Is there any way using a software to control the volume of the headphones individual volume?

Volume down and pause work perfectly. I even dropped the volume to the lowest. Only way to take it back up was unpairing and repairing to my phone.
