I've never much got on with in-ear rubber tips, and these were no different to any I've tried, despite reviews stating they were super comfortable.
My left ear is also worse to get it fitting right than my right ear. I have tried every size provided, none seem right. A grimace in the gym is enough to unseat even the most secure fit/seal, in either ear.
My main gripes specifically with AirPods Pro 3, which I've not seen in any other review;
- Because the rubber tips vary in size, the case has to accommodate the largest. This means if you're using small tips, there's a lot of spare room, which means the AirPods can easily be mis-seated, breaking the charge connection.
- The case is substantially bigger than AirPods 4 with ANC. I would say ~40%.
- The volume swipe on the stalk action is very tricky to trigger.
- Any stalk action is a bad idea when it's so easy to unseat them. I skip songs with a double press regularly, and nearly every time I had to push in and rotate after.
