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.

I dislike having to rate so low I dislike having to rate so low, but I must given utter lack of seal I get from these (size L). The choice to not publish measurements is questionable. I utterly wasted $$ for 3 pairs of tips that give me zero seal. Quality of materials seems fine, but does me no good. I now have oval-shaped ear tips that will sit in a drawer, unused )hopefully I can trade them at some point in the future.

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.

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

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.
