I fly in with hear like in helmet. Idk I guess I'd need to sit in an f1 with a headset on but I thought it sounded a bit off. I'm an aircraft mechanic and alot of times it is alot quieter and sounds different then what your expecting irl but for some reason I thought it sounded a bit funky. Ab sounds fine tho and I'm not bothered by it or anything. Hell during ground run and flight on real jets some jets make me sleepy with an almost harmonic pulse at certain power settings. Lol I'm sure tweaks will be made here an there with sounds anyway.
