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.

I am going to rate these personally in 2 categories. Fit/Comfort and Sound. DO NOT CLEAN WITH ALCOHOL. It will 100% ruin the surface of these and any silicone ear tips. Only soap and water like the manufacture states. Fit/Comfort: These are compatible with my Linsoul KZ ZS10 Pro. They do not fit my Alpha and Delta ks3 correctly has the bore length is to short. That causes extra pressure in the ear and that pops my right ear inserting the IEM. I am going to try the omni on those. I have tried all kinds of tips. Sizes and materials. I used to like foams. Then I got tired of replacing them. Quality of the foams also vary drastically from brands. They also started to irritate my right ear which I have issues with. Only 1 brand of foams do not irritate my ear. I looked for years for tips that fit and do not irritate. These are THEM! I have a tiny ear canal. So these SS(11mmx9.5mm) fit perfectly and they hold tightly. These are sticky and super soft. 100% med grade silicone. I can finally use my IEMs longer then 20min. You need to figure out which size you are and if they fit your IEM correctly. Do not only consider bore size and tip size, Consider also the bore length of how much it sticks out. If you do not you will waste a lot of money on these tips. They are worth the money because I have never felt this comfort before. Thank you spin fit! I will put pictures of the fit of the KZ vs the AD iems. Sound: So this correlates to the seal of the tip. The better the seal to the ear the better the sound frequency It outputs. On the KZ they increased the bass and details on highs. The AD KS3 did the opposite. It decreased the bass and details. This correlates to the fit. This is not the Tips fault, It is the fault of the buyer for not buying the correct tip size bore length. Not the overall length. The length of where the tip attaches to the IEM. If I did not own 2 different IEM's I would have never known this fact. Overall they deliver. If you get a better fit you get the most out of the IEM's period. For me these are the best silicone tips I have tried. So I give them a 5/5.

These are my FAVORITE ear tips. I am not a sound connoisseur - after years of rock my hearing ain't great. But I have a relatively amazing set of IEMs which seemed to be ever so slightly lacking in bass. These SpinFits actually seemed to help. I have spent way too much on things like cables and it never seemed to impact the music. But I think these DID. As for the fit and comfort I have no complaints. They fit snugly and seal properly. My IEMs never feel like they are falling out and they can be worn comfortably for hours. The design allows the ear tips to angle into your ear canal better than any other ear tips I have used. I think this is the secret to the great fit. The silicone feels better to me than foam or rubber. I highly recommend.

I purchased the SpinFit W1 ear tips in size Medium (Europe) after seeing many positive reviews. I can understand why they work well for many people, but they ultimately were not a good fit for me. I appear to have relatively small ear canal openings. Although I usually use medium tips with most IEMs, these felt slightly too large for my anatomy, especially when mounted on my Samsung EO-IA500 earbuds. Upon insertion, I had significant difficulty getting a proper seal and stable fit. Each time, I had to spend several minutes gently wiggling and adjusting the tips just to get the sound to balance correctly. The main issue for me seems to be the combination of size, softness, and overall shape. The W1 material is quite squishy, and the tip itself is slightly longer or taller than what I am accustomed to. When trying to push them in or adjust the angle for a proper seal, the opening would compress inward like a shock absorber instead of allowing the tip to rotate or settle naturally into my ear canal. This made achieving a consistent seal frustrating and time-consuming. Once I managed to get them seated properly, they sounded very good. Clarity and balance were exactly what I would expect from a well-designed ear tip. However, the effort required to reach that point made them impractical for daily use. I do not want to spend several minutes adjusting ear tips every time I want to listen to music. Because of this, I decided to stick with my usual silicone tips, which seal more quickly and consistently for my ears. I do not think there is anything inherently wrong with the SpinFit W1. They will likely be an excellent choice for many people. Unfortunately, due to my ear anatomy and personal fit experience, they simply were not the right option for me.

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.

What's the fuss about the SpinFit W1's? I prefer the smaller size ear tips and I have to say that these do not sound better than the OEM tips that came with my IEM's. First of all, the bore size for the tips were not true to fit like was stated in the description. I had to literally force the tips onto the IEM's when testing them out. Secondly, they are very tacky to the touch and there is not much room for adjustment because of the tackiness of the tips. You get a good seal, but I did not find them to better then some OEM tips. As for the sound. I did not prefer them over the OEM tips for the CrinEar Daybreak's or the Senn. IE600's. The Daybreak tips have more clear and wider soundstage, bass, and treble. I can hear finer details and a more open soundstage with the OEM tips. I tried the AZLA SednaEarFit Light tips on the Daybreak and got the same thing. The OEM tips sound better. I also did a comparison between the SpinFit W1's and the AZLA's with the IE600. The SpinFit's fit the IE600's better, but their sound was no better than the AZLA's on the IE600's. The main difference between the two was in the low end of the sound. The SpinFit's seem to muffle or hide finer details in the low end of the sound. The AZLA's are slightly better, but not by much. I wound up using the SpinFit's on a pair of Sony earbuds that I rarely use. Too much trouble to return them, I guess. LOL. For their price, I guess I expected a little better. However, I personally would not recommend them based on the fit and price. Your mileage may vary. Peace.

My Moondrop Variations stock ear tips were breaking part due to how I would try to pull them out of my ears without separating the drivers from them. So I needed some spares or alternatives. Tried a bunch but nothing worked. Either too big or too thin and foam makes my ears sweat. After some research I found the W1s. First time I used the Variations, it hurt my ears due to how large the nozzles were. After a while I got use to them. So I took a gamble with the W1 SS size tips since I heard they seem larger. But after trying them, no. They are about the same size as my stocks but better. On my stocks the texture were smooth and they didn't feel as secure. But that wasn't the issue. The issue is they were not secure on the nozzles as they would separate easily when pulling. So pulling the nozzles out with the tips in my ears were common. The W1s are a blessing. They are tight on the nozzles AND my ear canals. Not too thin and the texture is VERY grippy. So grippy that they almost hurt when pulling out of my ears. Worth it really. Despite the high price, I'm buying a second pair soon. They just work. Totally recommend these if you have trouble finding good tips for your Variations.

I bought these in the large size, and as someone who has always struggled to find ear tips that fit me perfectly, I absolutely love the way these feel. Snug, secure, and they passively block out a lot of sound on their own. They feel premium and fit my AKG buds perfectly.
