I just got a wireless void and immediately noticed (and was told) that my mic was suuuuuuuper low. After finding this forum and having no luck, i continued my search for a solution and stumbled upon a reddit post which said to give this https://sourceforge.net/projects/equalizerapo a try... I set mine to +15db and was amazed by the improvement... The noise cancellation still works as well...
So... Here's my 2 cents for what its worth...
P.S. @Corsair Chris, maybe you could forward this to the dev team so they could possibly implement some improvements to the firmware, so 3rd party utils wont need to be used...
