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.

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

Fine service - super product Fine service, but would prefer more shipping options. I bought the Model Y and they are nothing short of excellent. Solid build quality, phenomenal sound and stable connectivity. Everything you could ask for even at twice the price. 👍🏼🤩

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.

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.
