After some digging around, I figured out that you can actually change quite a bit if you enable the headphone accommodations setting in your audiovisual settings, just go to the AirPods menu and then cycle to accessibility, and in there, within the audio and visual settings you will find an option called headphone accommodations and in there you can customize your transparency settings, but I haven’t played with it that much but yeah, I guess I have really small ears because these XXS tips are perfect for me and I still apparently get a great seal, both from Apple’s point of view from their acoustic seal test, but also from just listening to the noise canceling and not really noticing any difference if there is a difference, it’s probably less than 5% it really fascinates me, my computer fan is quite loud in this room, and whenever I enable the noise canceling feature on the AirPods Pro 3, the only thing I can hear is a slight white noise, but I assume this is from the headphones themselves canceling all the frequencies, because I can’t hear even a bit of the computer fan, and on my Sony headphones, which are over your headphones I can actually still hear some fragments of the sound from the fan

A note regarding the fit: they seem to be really comfortable with the stock, default, ear tips, however, after about 10 minutes of use the right earbud starts, pressing against the earlobe a little bit, I guess I’ll have to switch to a smaller ear tip at least on the right side, because on the left, it seems to be perfect. I’ve heard some people on the Internet saying that. If possible, you should be using the largest ear tips that still fit you to have the best noise canceling and transparency experience, but probably that’s just speculation.
