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!

Ordered Eartune Fidelity U for my IER… Ordered Eartune Fidelity U for my IER Z1R. Best tips with this IEM after trying lots of eartips. Solved the recessed mids problems with some songs, especially male vocals. Hearing more elusive details too. The only thing making me hesitate to give a 5 stars rating is shipping is so so and expensive.

Just wow!! Just wow!!! As a musician this type of comfort is a new level, been playing drums and using finally my AirPods and oh man!!! They feel secure, sound cancellation has become high end better than your regular ear tips. They never fall off due to sweat or shaking your head. 100 out 10 highly recommended.

Great sound when you find the proper fit Great sound when you find the proper fit, which wasn't on the tips included in the box, but rather from the Model X tips that I saved when my X's case got destroyed. I'm my case those were the dome shaped tips. Great battery life and great band for the buck $$. I've hammering this puppies for over a week now that I can tell that there's s huge difference between them and the Model X. I fell in love with Adv-sound products several years and and I always recommend their products, very competitive in price, great construction and great sound quality. So far I have Model 3 Bluetooth(2017), Lightning(2018) and USB-C(2021) DAC Amps, Model X, Model Y and the Gaming Earbuds.

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.
