The ear buds looked great but… The ear buds looked great and were larger than other large earbuds that I have purchased as well as the original Apple ones. However, I still can’t pass the AirPods fit test. My ear canals are still too large, I have probably purchased at least 10 sets of large earbuds trying to find a fit. These are probably the closest. I have only passed the fit test once with some that I modified using a trick that I found on Reddit. It was difficult and complex and only lasted a few months. Thanks for at least trying to met the needs of customers with large ear canals-Apple won’t. I wonder why because there are undoubtedly many thousands like me. I will use these because they were the best that I have found so far. Maybe XXL in future.

Price is "custom", execution is not Price is definitely "custom" (one pays a premium for something that's customized to oneself), but the execution is absolutely not. The ear plugs are really small, and while they fit reasonably well, they do not insulate sound like their larger cousins from ADV sound do (ADV sound is the side of the company that does custom IEM tips, and those both fit in well, and insulate sound much much better). Now I do need custom tips to help me sleep, but these are simply not the solution. They are simply way too small and shallow to work well. In fact, Mack's ear plugs work a lot better (though they are disposable ....) I feel cheated.

Workout resilient Fit was good…. Earbuds really stayed put during a tough workout - both during heavy weights and zone 5 HIIT training…

Expensive and worrisome Although the earplugs are advertised as being for sleep, sadly they do get a bit painful in the middle of the night from the pressure they place on the outer ears. And they do create a pressure in the ears that possibly seems dangerous to the health of the ear. I’m not convinced they are actually safe.

Must have foam replacement tips These foam AirPod tip replacements make all the difference in daily use. I always felt like the original silicon tips were loose and didn't fit well. I was afraid they were going to fall out at any moment when I was moving around. Comfort, security, and improved sound. Apple AirPods should be shipping with these from the factory.
