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. Review: Snug fit and stays in place. Non irritating medical grade material for sensitive ears. - 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. ## Features - Double W-shaped Tube Core to Enhance Stability. - SpinFit patented spinnable 3D axis that bends to fit unique ear canals' angle like customized. - Medical-Grade silicone reduces allergic reactions. - HOT seller among audiophiles. Most affordable upgrade of the sound and wearing experience to IEMs. - Fits nozzle diameter of 5 - 6 mm. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CLRSVRTN | | Best Sellers Rank | #2,813 in Electronics ( See Top 100 in Electronics ) #47 in Headphone Earpads | | Brand | SpinFit | | Compatible Devices | Earphones | | Customer Reviews | 4.4 out of 5 stars 1,458 Reviews | | Enclosure Material | Silicone | | Global Trade Identification Number | 04713037521337 | | Item Type Name | Replacement Ear Tips | | Item Weight | 0.01 kg | | Manufacturer | Rextec International Limited | | Material | Silicone | | Mfr Part Number | MS | | Model Number | MS | | Number of Items | 2 | | Unit Count | 2 Count | | Warranty Description | 30 Days Warranty Against Manufacturer Defects | ## Product Details - **Brand:** SpinFit - **Compatible Devices:** Earphones - **Material:** Silicone - **Number of Items:** 2 - **Unit Count:** 2 Count ## Images ![SpinFit W1 for IEM - MS - Patented Medical-Grade Silicone Ear Tips, Double W-Shaped Tube Core, More Stability - Image 1](https://m.media-amazon.com/images/I/51TEvvn6ffL.jpg) ![SpinFit W1 for IEM - MS - Patented Medical-Grade Silicone Ear Tips, Double W-Shaped Tube Core, More Stability - Image 2](https://m.media-amazon.com/images/I/61XFOxdYX2L.jpg) ![SpinFit W1 for IEM - MS - Patented Medical-Grade Silicone Ear Tips, Double W-Shaped Tube Core, More Stability - Image 3](https://m.media-amazon.com/images/I/61QkYgLLCUL.jpg) ![SpinFit W1 for IEM - MS - Patented Medical-Grade Silicone Ear Tips, Double W-Shaped Tube Core, More Stability - Image 4](https://m.media-amazon.com/images/I/71IUUOLAoTL.jpg) ![SpinFit W1 for IEM - MS - Patented Medical-Grade Silicone Ear Tips, Double W-Shaped Tube Core, More Stability - Image 5](https://m.media-amazon.com/images/I/71PVOt9jicL.jpg) ## Available Options This product comes in different **Model** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Comfortable and grippy, but sadly only in one ear *by S***M on April 28, 2026* I have generally smaller ears, with the right ear canal smaller/narrower.

So I give them a 5/5. ### ⭐⭐⭐⭐⭐ Good Fit & Good Sound *by W***S on September 20, 2025* 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. ## Frequently Bought Together - SpinFit W1 for IEM - MS - Patented Medical-Grade Silicone Ear Tips, Double W-Shaped Tube Core, More Stability - Linsoul DUNU S&S Silicone Eartips S/M/L (3pairs) for Nozzle Diameter from 4mm-5.5mm for Stage Studio, for KZ ZS10 Pro, 7HZ Zero, Orchestra Lite, TANGZU Wan'er S.G IEM (S/M/L- Each Size 1 Pair) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/592613204-spinfit-w1-for-iem-ms-patented-medical-grade-silicone-ear](https://www.desertcart.tn/products/592613204-spinfit-w1-for-iem-ms-patented-medical-grade-silicone-ear) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-22*
