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.

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.

Pricey perfection! 4.5 Stars. Everything was excellent! Fitment, quality, and customer service. These personalized tips are exactly what I expected. My only two complaints are that the process/ product cost me around $300 ($50 per ear impression and $199 for the product) and the quality of the noise cancellation feature in my AirPods Pro 2nd generation is slightly worse than the stock tips.

I got the order sooner than I expected I got the order sooner than I expected. The custom fit was very comfortable. I have ears that itch a lot and these didn't cause any problems with that. I didn't hear any lose of quality for my 64 Audio U6t's. Very pleased with my purchase

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