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.

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!

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 stay in any better than the rest Similar to the other memory foam earpieces, these squeeze and then expand into your ear canals and feel good at first. But gradually this pressure squeezes them out of your ears. This is the 5th after-market vendor I have tried and I am now officially giving up.

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.
