Don't work as well as the ones that come with the Airpod Pro 2 I ordered the medium ones, which is what I use for other products. The product claims to improve noise cancellation by making a superior seal with your eye. In my tests, they made less of a seal than what comes with the air pod pro 2. Very disappointed.

I dislike having to rate so low I dislike having to rate so low, but I must given utter lack of seal I get from these (size L). The choice to not publish measurements is questionable. I utterly wasted $$ for 3 pairs of tips that give me zero seal. Quality of materials seems fine, but does me no good. I now have oval-shaped ear tips that will sit in a drawer, unused )hopefully I can trade them at some point in the future.

Good but not revolutionary I like that they are attached to their own pieces, however i had to use the original earpieces over these and fit them inside to make them actually seal. I have the comply ones and the foam in these don't rebound as fast (good thing, the fast rebound tends to hurt the ear). However, if you remove this from your ear and put it back, the foam is a little slow moving so it wont seal and may not even sense the headphone is in your ear. So you are left leaving it in your ear. The perfect fit was this, i had to remove the foam from the attachment (snaps off), and physically remove the rubber inner ring, and then take the original apple earpiece, and put this foam inside that. This is the only comfy way to get a good seal every time.

Model 3 Mobile As always, an excellent and high-quality product. The Model 3 mobile earbuds are something I’ve been wanting for quite some time and they have not disappointed. Excellent sound quality. Advanced is a gem shining in the mountain of other products out there. I look forward to many years of enjoyment.

Foam Earbud Tips These foam tips made use of my airpods pro much more enjoyable. My headphones haven't stayed in, and stayed sealed this well since I got them. Just would've hoped to not pay as much as I did for shipping, though I did appreciate that I received them in 2 days!
