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.

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.

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.

Fidelity U eartips perfect for JBL Reflect Flow Pro Love the sound of the JBL Reflect Flow Pro earbuds, but their stock eartips were uncomfortable and didn't fit well. Tried using foam eartips from a different brand, and they also felt uncomfortable. The round shape just didn't fit well in my ears. Eartune Fidelity U eartips are exactly what I was searching for: lightweight silicone, flexible and comfortable, create a great seal, and don't slide out of place. My only regret is not finding these first!! Now, I can wear my JBL earbuds all day with zero discomfort.

Never got my package -
