All good, you can always tweak the sensitivity of your microphone to pick up noises but ofc when you are transmitting you might be able to hear engine noises. (call it realism 
) Probably a better idea to balance the volumes and just using headphones, though. My situation is different to where I’m using the oculus quest 2, the speakers are RIGHT next to my ears, this means it’s much quieter than the use case of speakers from a distance.
