Final Audio Black+Black/Red Silicone Type E Eartips kit with Case and Nozzle Adaptor Compatible with AKG, Audio-Technica, Beats by Dre, Campfire Audio, Empire Ears, Shure, Sony, Westone (Large)

I got these for my Noble K10Us and these were perfect. The Nobles are a finicky pair of IEMs and tip rolling for them is a real pain, because of how massive their nozzles are. Getting a comfortable fit that stays paired with a nice seal is very tough with those. These gave the best results, both sonically and comfort-wise. They were better than SpinFits, better than Spiral Dots, and way better than Complys. I can only imagine they would have a similar effect on other large nozzle IEMs.

Material feels top notch and sound as well as fit is great on my Sony WF1000XM4

I bought the multipack first to figure out which size to get. I got these to replace the stock on my Sony mdr-EX800st which kept slipping out. I found the medium size and smaller degraded the bass which muffled mids significantly. The large gave a bit of a boost while still keeping clarity which is why I stuck with it. I'm usually a small or medium but the large fit nice and snuggly in my ears. Now the sound is perfect for my hearing. The sizes do matter!

I love the ease of installation and the choices of fit. Easy to swap out and the case is handy

Good snug comfortable fit. Much better the original Sony. Quick seal every time.

After trying these, they are not at all noise canceling and awful for live music performance.
