Superb Products and customer service.A++ I have been a regular customer of Adv products right from model 3 time (which is still a great.earphone btw) and when they were called advanced sound. I am truly a fan of their customer service. Although I am based in Australia but they have always responded with utmost sincerity - understanding every aspect and responding in a truely supporting way. I had an issue with a Model 3 last to last year and a Model X+ few days back and they have always taken care of me Love your products and the customer service. A++ Cheers, Ashish

Great product with exceptional sound… Great product with exceptional sound quality. I plan on purchasing from ADV. in the future.

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!

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.

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.
