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.

Fine service - super product Fine service, but would prefer more shipping options. I bought the Model Y and they are nothing short of excellent. Solid build quality, phenomenal sound and stable connectivity. Everything you could ask for even at twice the price. 👍🏼🤩

Crazy fast shipping. Top quality product. I ordered these and they were on my doorstep within days. This is my 2nd time ordering from ADV. Their foam airpod pro eartips are far and away the highest quality I’ve purchased and used. They fit flawlessly in the case, drastically improve the noise cancellation, and are easier to install than the silicone eartips provided by apple.

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.

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.
