Yes it is a good question I'd love to have answered by someone who actually knows. Overwhelmingly, judging from having watched thousands of reviews and lived many decades to know that the ordinary consumer is by definition deaf, when it comes to realistic expectations regarding no noise or low noise. That's why you have to pay a premium to get something that's ACTUALLY low or no noise, something Apple has failed at delivering, despite offering a "Pro" line-up, (partly, and this is pure speculation, due to the fact that most normal people are hard at hearing or very forgiving due to other noise in their subpar living or working environment), and given that the Mini does not have the "Pro" stamp of "approval" it becomes an even better question, which is why I ask.
