The sound is amplified by the Equalizer APO+Peace Equalizer, UI for Equalizer APO software.
We put both, after starting we move the upper horizontal slider. :)
There are guides on the internet on how to do it.
Pros
Full set
Easy Installation
Cheapest Capacitor Mike :)
I tried it myself, gave it to my brother for DR.
The box is very stylish, you can give without additional packaging.
Cons
Not sure, but maybe the sound quality. I had a Samson c03-U and it sounded the same.
But due to my unprofessional hearing, I can not judge for sure.
Definitely a minus that you can not amplify the sound in the standard way of Windows.
