Wish I’d seen them sooner. I couldn’t believe the difference these tips made in the sound quality of my Second Gen AirPod Pros. The the sound quality, volume, bass and noise reduction all very noticeably better. Plus the improved seal makes them much more secure. They stay tight and secure when running and biking. And for the first time i can wear they kayaking. I always feared one would fall out right into the water, but not anymore. If you’re unsure of the size, I’d go with the large. The memory foam like material can be squeezed, then expands in your ear to give that improved seal. The price is a huge bargain for the increased quality of sound you get.

Nismo Gaming Jr. (They are better than their 30$ price tag , worth the money) I've received their amazing headphones a month ago. The left ear piece fell out due to error, but they didn't hesitate to provide me with a replacement in hope that it was a faulty pair. The sound is extremely good for the price. I would suggest these to content creators who need great sound quality, including that it works very well with VR Headsets that include a 3.5mm Headphone Jack.

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.

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.
