Wish I’d seen them sooner. I couldn’t believe the difference these tips made in the sound quality of my Second Gen AirPod Pros. The the sound quality, volume, bass and noise reduction all very noticeably better. Plus the improved seal makes them much more secure. They stay tight and secure when running and biking. And for the first time i can wear they kayaking. I always feared one would fall out right into the water, but not anymore. If you’re unsure of the size, I’d go with the large. The memory foam like material can be squeezed, then expands in your ear to give that improved seal. The price is a huge bargain for the increased quality of sound you get.

Almost there...😉 The purchase & shipping experience is hustle free. ✔️ The audio delivery is exquisite. The vocals come out crisp - including overtones on individual artists. The treble could do with a slight touch up. The bass is just right for the required balance and all the instrumentation is also showcased decently. Inclusion of foam tips would further enhance the experience. A steal for the package. I recommend them to anyone who'd like to enjoy a total sound experience for a decent prize.

Don't stay in any better than the rest Similar to the other memory foam earpieces, these squeeze and then expand into your ear canals and feel good at first. But gradually this pressure squeezes them out of your ears. This is the 5th after-market vendor I have tried and I am now officially giving up.

Great product with exceptional sound… Great product with exceptional sound quality. I plan on purchasing from ADV. in the future.

Custom tips for Z1R Fantastic experience doing business with ADV. I ordered a set of custom tips for Sony IER-Z1R. ADV delivered a perfectly fitting set of tips in far less time than originally estimated, and was also able to deliver 3D scan files of my ear impressions for further use.
