A:AnswerWhen the headset is on and the noise canceling is set to 10 it does a very good job of muting your surroundings. I would say it would likely mute or make reasonable someone snoring near you. Obviously it would depend on the snoring decibles.
A:AnswerI would say it depends what you are connecting it to. They're bluetooth so they don't have a wireless USB dongle. I've used them more for sound vs conversation, but they worked great for me no matter what I connected them to. I have a ps5, had them for meetings n games/ music on my PC, and for music. I also have a Corsair Virtuoso set specifically for my PS5, but these are actually more comfortable. They fit better because I have a smaller head.
A:AnswerDolby Atmos compatibility depends on the source unit itself along with the source material and application that's being used. The headphones will reproduce the sound based on the digital feeds being used.
A:AnswerI was able to replace the ones from my old Bose headphones, but just to be sure you can call the company, as they have excellent customer support. The foam on the head piece, however, was not replaceable.
