I dislike having to rate so low I dislike having to rate so low, but I must given utter lack of seal I get from these (size L). The choice to not publish measurements is questionable. I utterly wasted $$ for 3 pairs of tips that give me zero seal. Quality of materials seems fine, but does me no good. I now have oval-shaped ear tips that will sit in a drawer, unused )hopefully I can trade them at some point in the future.

Don't work as well as the ones that come with the Airpod Pro 2 I ordered the medium ones, which is what I use for other products. The product claims to improve noise cancellation by making a superior seal with your eye. In my tests, they made less of a seal than what comes with the air pod pro 2. Very disappointed.

Model 3 Mobile As always, an excellent and high-quality product. The Model 3 mobile earbuds are something I’ve been wanting for quite some time and they have not disappointed. Excellent sound quality. Advanced is a gem shining in the mountain of other products out there. I look forward to many years of enjoyment.

Crazy fast shipping. Top quality product. I ordered these and they were on my doorstep within days. This is my 2nd time ordering from ADV. Their foam airpod pro eartips are far and away the highest quality I’ve purchased and used. They fit flawlessly in the case, drastically improve the noise cancellation, and are easier to install than the silicone eartips provided by apple.

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.
