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.

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.

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.

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.
