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!

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.

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.

Great Seller of Audio Products and Accessories Great seller of audio products and accessories! Had an issue with an order and they were prompt, courteous, and kind with replacing an incorrect shipment. I've purchased a few things from both Adv and their sister site, Eartune, without issue. Heard about the site from an audio reviewer website that had reviewed the Model 3 Wireless headphones (which were the first thing I bought from ADV). Since then I've purchased a wireless bluetooth receiver, a USB C to 3.5mm headphone adapter, as well as some eartip replacements! Overall a great site to buy some underrated products!
