Like the title says, it would be very, extremely useful a separate volume slider for the "helmet" sim volume.
Since it's available in the sim, in cockpit I only use "hear like in helmet" feature, is very very cool and realistic.
But very often for learning reasons ( or just for fun ) I have to switch from F1 visual to externals, and the volume difference just hurts my ears.
Also when ejecting, the out of cockpit volume is so loud that I have to remove my headphones very fast to avoid hearing damages.
Please, please please implement this feature.
Thanks!
