SpinFit CP800 for Thin IEM Nozzle - L - Patented Silicone Eartips for Replacement (2 Pairs) (for Nozzle diamter from 3-3.5mm)

I have sets of S4A and S4i Klipsch in-ear headphones that I absolutely love. I bought them probably 15 years ago and are long since discontinued, but they sound like the day I bought them. The factory silicone tips lasted a very, very long time, but are now having a hard time holding their shape and sealing out noise. I thought about buying some of the aftermarket Chinese tips with good ratings on here, but instead gave these a shot despite them being considerably more expensive. The CP800's fit the narrow tubes/posts perfectly, and are so much more comfortable than the OEM tips. They fit perfectly in my ear canal. One of the problems I had with the OEMs was that my ear canals were every so slightly a different size, but not enough so that using two different sized tips would fix that. These tips go down inside the canal that this is no longer an issue.

Great eartips but the sizing is not correct. I wear large eartips in every other brand of eartip, even the SpinFit CP240. I like the CP240 and wanted to try a single flange tip and picked these up. I immediately noticed that the seal that I was getting was not that great so I started looking at these. I verified on the packaging that they were indeed large but when I put them beside Shure or Comply large these were noticeably smaller. Placing them beside a pair of Shure medium that came with my IEMs they were the same size. If you buying these then be sure to order a size larger than you normally would. Unfortunately for me there is no Extra Large option

Eartips are as important as the earphone itself as it impacts the sound transmitted to the ears. You can alter the sound signature and quality with different eartips.Spinfit eartips is a serious upgrade over the stock silicone eartips for comfort and sound clarity. These are well made and I have used this with Phonak Audeo IEMs which is my go-to earphone. I find that Spinfit brings out the details, has more isolation (or increased sound for the same volume) over the silicone eartips that I have tried, this includes Sony hybrids, foam eartips and monster gel and foam eartips.Recommended!!

Spinfits run small. These "large" tips are maybe half a millimeter larger in diameter than Shure's medium silicone tips. These are barely big enough for my ears, but they do sit a bit deeper and give me a more consistent seal, which tips from Shure, Westone, and others can't do.

Beautiful. Went onto my Shure SE215s like a glove and suited my ears way better than the stock large silicon tips. Didn't make my ears scream for relief after 10 minutes and gave pretty consistent, beautiful sound. All in all if you wanna upgrade from the stock tips and double-flange isn't your bag then get these.

Ordered these after reading reviews. Have shure 535 and 846 and they aren't as good as the yellow foam ones I buy. The yellow ones seal so more sound overall gets in your head. Bad 20.00 for two pair

I got my first spinfit experience with the ones that came with my n5005.They're very comfortable so I was wondering if spinfit would make my shure se846 fits better.They're the large cp145's so I ordered large cp800 for my shure. However, they do not meet my expectation.CP 800 has different shape as cp145 so they tend to suck air our of my ear canal which is not a good experience.Looks like I wasted 11 dollars.

I love Spinfits! I've used them with numerous IEMs with great results. This pair went on my NuForce HEM8. Normally I use medium tips but these IEMs have a shallow fit so I had to use the large tips, but they were still too small and just wouldn't get a good seal. The large Spinfits gave me a perfect seal and made these IEMs keepers.
