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

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.

Item came resealed with glue. Can tell it has been ripped open and used at least once. Had to wash it before use. The item does have a better seal than the factory tips I had offering a slight reduction in noise, but if you are looking for complete isolation this does not do the job. You can still hear background noises clearly just at a lower volume, can hear a fan or closing of charging case. Usable decided to keep since it was cheap. Tested in traffic and under a tunnel. The tips hold up and the seal prevents distortion of sound from high wind and loud environment.

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.

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.

Considero que estos son mejores que los CP100 plus, proporciona mayores bajos y tiene mejor agarre. También reduce un poco la sibilancia (lo cual encuentro como positivo). Son más alargados por lo que entran más profundo al canal auditivo sin tener que empujarlos mucho. La punta es más firme y no se regresa hacia afuera como me sucedía con los CP100 plus. No causa incomodidad. Como siempre, la silicona es de alta calidad. Los probé con unos Sony MH750 y calzan a la perfección.

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.

イヤホンはEarFun Air Pro 4+で、W1-Sサイズを使用。 取付はEarFun Air Pro 4+の本体側フランジの直径が太い為ねじ込む感じになりますが、抜けにくいので普段の使用時に困る事はないでしょう。 低音の伸び、女性ボーカルの輪郭、全体的な解像度(特に高音域)が明確に向上します。 バスドラムのフロア感がよい。 装着感も吸いつくような感じで密閉感と共に良好です。 情報量が増える為、人によっては聴き疲れしやすくなるかもしれません。 しっかりケースにも収まり蓋の開閉も干渉する事なくスムーズです。 過去に「水月雨 Kadenz」や「qdc SUPERIOR」などのボーカル重視の有線イヤホンでも使っていましたが、同じく低音とボーカルの輪郭が上品にブーストされ良好でした。
