I just commented on another thread but will add a note here too. I went to an Apple Store today to try on the new Airpods after seeing so many 'my ears hurt, they are too big' type posts here and elsewhere. A few moments in store was enough to convince me that I wasn't going to be in that crowd. I'd suspected as much as I have bigger ears and although I loved my 1st gen Airpods (still kicking after 3+ years) the bass would get lost because they didn't sit in my ears just right. I had used the little fuzzy stretchy covers like old school headphones have and that would mostly solve that problem.
I'm a couple hours in and it is like the gen 3 Airpods were made for me. The fit is perfect, I jumped around a bit to see if I can get them to fall out and they did not, I can hardly tell that they are there and they sound amazing. I also have Airpod Pros (on my 3rd pair which thankfully has not had the same crackly failure as the first two pairs) and I'd say these sound as good as those do, but without the silicone tips which make my ears itch after a while. I don't think I'll need to go above 50% volume, as that is plenty loud. I am very pleased so far.
