SpinFit W1 for IEM - M - Patented Medical-Grade Silicone Ear Tips, Double W-Shaped Tube Core, More Stability

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.

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.

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.

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.

These medical grade silicone ear tips are the best in the market place. They do not irritate the ear canal and can be worn for a longer duration. They are available in many sizes which will accommodate most ear canals.

They are great . Perfect seal and good for bass. I highly recommend them

Excellent comfort and grips onto the IEMs very tightly. Is a little pricey for eartips though, but I think it's well worth it considering the comfort and multiple size options.

Punte utilizzate sulle iem Moondrop Blessing 3 Aqua e sono ottime. Ho delle orecchie piccole e i gommini in dotazione delle iem erano troppo grandi e non comode. Queste SpinFit di taglia SS mi permettono invece di tenerle comodamente anche l’intera giornata, senza che scappino dell’orecchio, o creino alcun dolore. Avrei gradito una taglia con qualche mm in meno, ma va bene anche così.

Después de probar muchas marcas, finalmente encontré SpinFit, y ninguna otra había conseguido que me olvidara por completo de que llevo puestos mis auriculares. El material de estas puntas se adapta perfectamente a la forma de mi oído e incluso mejora la calidad del sonido, aunque no sé exactamente cómo lo logra. Además, me deshice por fin de las molestas caídas constantes con el más mínimo movimiento. Estoy utilizando este producto como sustituto de las puntas de memory foam de mis WF-1000XM5, que me resultaban incómodas y no se ajustaban bien a la forma de mi oído. Si están buscando las mejores puntas para auriculares, no lo duden: estas son la mejor opción.

New to IEM’s but not to quality audio equipment. Bought these for my Truthear Hexa IEM’s, which are cheap but deliver a nice sound with a slight lean to the bass end of the spectrum. These Spinfit W1’s fit snug on them but they do go on fine. They have grippier silicone than the stock ones and it is much softer and feels more comfortable to me. The sound is actually improved. I found the Hexa’s detailed and have great texture but slightly veiled in the upper mids. These W1 ear tips make them sound clearer, with more air in the mids. The bass is tighter and more controlled and doesn’t seem to affect the mids as much. The soundstage seems wider too. If anything the treble is thinner but there is a little sparkle right at the top end I hadn’t noticed before. In my opinion these deliver an overall improvement in sound quality and comfort.
