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!

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.

Ordered Eartune Fidelity U for my IER… Ordered Eartune Fidelity U for my IER Z1R. Best tips with this IEM after trying lots of eartips. Solved the recessed mids problems with some songs, especially male vocals. Hearing more elusive details too. The only thing making me hesitate to give a 5 stars rating is shipping is so so and expensive.

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.

Missing Package Made Right I had an issue where my package was marked delivered by USPS but it wasn’t in my mailbox. I emailed support and was contacted right away that a second package would be sent to me and confirmed my address. I got the new package a few days later (along with the original one as well— thanks USPS). I was so impressed by how prompt and helpful they were in making things right even though it was obvious the mistake wasn’t on their end!
