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.

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.

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!

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

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.
