Windows 10: Bluethooth headset volume too low when using communication platforms

Lumia 920 low call volume in bluetooth headset.

I have low volume during calls in my bluetooth headset Nokia BH-310 connected to Lumia 920 even on maximum 10/10 volume. I realize that the problem is not in headset (headset is much louder when is connected to Nexus 5) so the problem must be in the phone.
This headset has not separate volume control and the volume is controled only from the phone. Is there a vay to increase bluetooth headset volume on Lumia 920?

I have Nokia Black update installed in the phone.

default setting somehow?

 

Good surround sound headset

I know you say you're not that guy, but stepping into the $250+ range really brings a change in build quality that might have you never having to buy another set. Otherwise, getting 6 speakers with decent sound in a headset is hard, and that's what you are asking for, and I have no suggestions, but just a bump up the list. *Stick Out Tongue
