I've tested it with Su-27, less painful when I moved my "head" with canopy open, also positioning is not that bad. I did few minutes of testing with F11.
I don't like to listen to music from youtube, unless it's uploaded by someone competent "cough" potato codecs "cough".
I will probably use it only for DCS as other games I play tend to have better sound design.
Overall it sounds like someone wanted to emulate home cinema speakers with all it's downsides.
