The sidetone feature is great, however I find that the volume is too low to be of practical use, especially when using ear plugs. The only way I can increase the sidetone volume is to increase the overall volume, which results in blowing my eardrums when someone speaks over the phone or intercom. It would be great if you could make the sidetone volume configurable in the settings so that it is possible to select a significantly higher volume setting than current default. Even better would be if sidetone volume could be set completely independent from the different volume settings for different audio sources, i.e. the sidetone volume would always be set to the level you have configured, no matter what volume level you have set for the current audio source.
