bought these to put on my 7hz salnotes zero and zero 2 IEM's (so far I've only tested the regular Zero). I was having issues with chaffing on a regular pair of JLab M silicone tips that made me switch to their small cloud foam tips, this changed the sound profile a bit by reducing treble just slightly, but those being foam it also made a better deal which helped the bass a bit on those which sit a little back in the sub-bass area (regular zero lack that thump due to a more analytical tuning). So, I wanted to give silicone tips a try again and came across these, the medical grade silicone is soft but sticky and makes for a great seal in the ear, I haven't felt any itching or chaffing so far after a few hours, so I can so far say that the regular silicone tips I used before are no longer going to be put on anything ..in fact I'm gonna replace the tips on my wireless earbuds with these too. The size runs a size bigger, normally with skullcandy or JLab I was using the Medium tip, but with these the MS (medium small) were just about the same fit as those. I might actually get the small because my IEMs don't sit flush against my ears and those would most likely fit a little deeper like the cloud foam tips did for me. As for sound ..my 7hz salnotes zero IEM is a neutral balanced tuning, with the foam tips I can tell the highs were slightly lower and some details in certain sibilant areas didn't sound as sparkly as they should given the tuning, the foam seal helped the bass a bit though. Now for the W1. These not only brought out more clarity in the balanced tone, but it upped the low end a bit where it was brought a little bit forward and wasn't lost or masked while retaining it's set tuning, In fact the bass seems present and tight but not boomy (don't expect a punch from the low end here) which is what you want in a neutral balanced set the mids were nice, clear and kept the balance of the intended tuning, the highs also retained sparkle that was originally rolled off with the foam tips. So in the highs I could hear the faint details from before a little more, but it's not overly sharp. Putting them on is a little tricky at first, they're a tight fit but secure well onto the stem, though I probably would make these permanent on the IEM's I put them on, each one would respectively stay on the ones i put them on, as I heard about these loosening if put on stems with wider diameters and then being too loose on smaller diameter driver stems. The soundstage is a bit more open, I can tell more separation between instruments too. Overall, these tips are great, I may purchase more in MS and S for my Zero 2 and my wireless earbuds.

I have generally smaller ears, with the right ear canal smaller/narrower. I typically go from 10.4-11.2mm on the right ear and 10.6-11.5mm on the left ear. I've tried many eartips like the Velvet narrow and wide bores, Dunu S&S, Azla Origin, etc. All my eartips are tested on the Kiwi Ears Septet (my main IEMs) and the LAN II Ref. On the LAN II Ref, it was comfortable and felt very nice and secure in my ears. On the Septet, for my right ear, due to the more sensitive canal, using the smallest SS (11mm) size, the harder silicone in the middle seemed to irritate it and caused fatigue consistently after ~2 hours of use and needing at least an hour of rest. My left ear was perfectly fine and they felt amazing there. TMI but I have wetter wax and my canal heats up easily, just pushing the tips into my ear would have them lose their grip, but inserting the eartips with the ear pull method (hold the top back of ear and pull up and back slightly to open up the canal) and I was able to eat easily and not have to readjust the eartips back into my ear. Although the eartips themselves I'd give a 4 due to them hurting my right ear and being a little expensive, I'm giving them a 5 instead due SpinFit's customer support being really helpful and professional! On a separate note, what ended up working for me instead was their SpinFit NEO, they're more comfortable, subjectively produced a nicer sound profile for my ears, and hasn't caused my right ear any fatigue in both my IEMs, especially the Septet that's harder to keep comfortable due to its bulky size.

The **SpinFit W1** ear tips are easily one of the best upgrades you can make for your IEMs. They’re super comfortable and the flexible design helps them fit naturally in your ears, which makes a big difference for long listening sessions. The seal is excellent, giving you better bass and overall clarity without messing with the sound too much. They also stay in place really well. Simple upgrade, big improvement.

They stay seated in the ear very well with a nice sound-seal and are aesthetic, but the “stickiness” makes them slightly more difficult to get in when constantly standing up and sitting down at a desk when compared to others like divinus velvet. Overall high quality.

I have several pairs of these on multiple pairs of IEM’s and like them very much. Find that while the seal for getting the best sound and noise isolation is not as good as foam Comply tips they are good and much easier to keep clean/disinfect and are much longer and better wearing. I do recommend these and plan to continue ordering these in the different sizes as I need them. Whilevthey’re a little bit expensive. I think that they are worth it and have really found very few issues with them as far as once they are properly fitted having them come off of any of my IMs and getting stuck my ear canals where they don’t belong or anything like that. They are also pretty comfortable for quite long listening sessions for the most part so I’m also happy with that. Would be nice if they were a little bit more cushioned but I also understand why that may not be possible. But I regularly go several hours with the in my ears without major discomfort issues. I’m not sure how these would be if you are using them on IEM’s underneath hot stage lights while doing a lot of active movement because this is a scenario I have yet tried with these. I also am a fan of these because I discovered that I am allergic to a lot of of the different ear tips on the market and have not had the same issues with these.

I bought these to replace the ear tips on my Loop earplugs, and they attach nice and snug. They're maybe even a little more comfortable than the original ear tips. I love my Loop earplugs for the noise reduction, but the inexpensive silicone ear tips they came with were giving me contact dermatitis, and my ears were SO itchy. My brother-in-law is a chemist specializing in plastics, and he suggested that the problem isn't from the silicone itself, but from using an inexpensive chemical to cure it. That makes sense, as I've used other medical grade silicone products with no issue. I'm so glad to have these replacements, as I missed wearing my earplugs.

Good while it lasted. I provided a solid and snug fit until it didn't anymore. It kept falling out when I would take it off my ear causing me to lose it, find it and repeating the cycle until I just switched back to the original ones that came with my IEM.
