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. Review: Comfortable and grippy, but sadly only in one ear - 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. ## 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 | B0CLRV8GSX | | Best Sellers Rank | #2,856 in Electronics ( See Top 100 in Electronics ) #47 in Headphone Earpads | | Brand | SpinFit | | Color | Green | | Compatible Devices | Earphones | | Customer Reviews | 4.4 out of 5 stars 1,456 Reviews | | Enclosure Material | Silicone | | Global Trade Identification Number | 04713037521320 | | Item Type Name | Replacement Ear Tips | | Manufacturer | Rextec International Limited | | Material | Silicone | | Mfr Part Number | M | | Model Number | M | | Number of Items | 2 | | Unit Count | 2 Count | | Warranty Description | 30 Days Warranty Against Manufacturer Defects | ## Product Details - **Brand:** SpinFit - **Color:** Green - **Compatible Devices:** Earphones - **Material:** Silicone - **Unit Count:** 2 Count ## Images ![W1 for IEM - M - Patented Medical-Grade Silicone Ear Tips, Double W-Shaped Tube Core, More Stability - Image 1](https://m.media-amazon.com/images/I/518KS3bDyaL.jpg) ## Available Options This product comes in different **Model** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ I'll never go back to using stock silicone tips that come with IEM's and wireless ear buds. *by N***2 on April 23, 2025* bought these to put on my 7hz salnotes zero and zero 2 IEM's (so far I've only tested the regular Zero).
