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.

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.

Foam Earbud Tips These foam tips made use of my airpods pro much more enjoyable. My headphones haven't stayed in, and stayed sealed this well since I got them. Just would've hoped to not pay as much as I did for shipping, though I did appreciate that I received them in 2 days!

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.

The ear impressions are really comfortable The ear impressions are really comfortable and I can wear them for a long time. They really enhance the sound by blocking noise. I would like to have received more detailed instructions to insert the custom buds into my ears. I had to use trial and error to figure out the optimal way to insert them.
