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

You wouldn't think earphones would sound better with different eartips nor did I but here we are. I have sennheiser ie200 so some good iems but with these eartips the seal of the ear from the outside noise was a night and day difference, providing you have the right size of course. The sound felt like it wasn't so quiet and distant, it was like the speaker was in my ear instead of a feet away. Thanks to the texture of the material the eartips are I was able to use these in intensive biking at the gym and not once did they loose grip and gradually fall out of my ear. Best thing I bought just wish I knew about these sooner. You won't regret buying.

Used these on Mangird Tea Pro. Fit perfectly on the eartip holders. The sizing was the same as the sizing for the eartips that come with the Tea Pros, at least for medium. Compared to the stock tips, these have a noticeably better seal, and stick more easily in my ears. I find that I can talk or sing along with music without the tips moving at all or causing jaw pain (since they are both stickier and have more give to them). I didn't notice much difference in the sound, maybe some small changes to the treble and slightly more bass due to the different seal; the mids were unaffected which is important to me because I love the mids on the Tea Pros.

I bought these because I've seen various reviews raving on them and ordinarily I'd stick with foam because they are pretty much my go to with my IEM's. The is sound good but a bit more clinical than the foam and the fit was fine (Medium). The only downside they did not stay comfortable for long and for me they made my ear canals itch, maybe I have an allergy to silicone. Overall they do sound good but the price for one pair I feel is a bit much. I think I'll be sticking with my Comply foam tips.

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.

I had high hopes for these after suggestions from others, as I get terrible allergic reactions to normal earbuds. Unfortunately I’m still reacting after using these, although the reaction does occur after a few hours wear. They’re very comfy however!

Fit well, seal tight in my ears and are great for audio and feel durable because i am rough with my tech and I haven’t damaged them i think they are worth the price if you are deep in the iem/audio hobby and want some great eartips

Do not buy these. They are the worst. They do not enhance any bass effect, they nullify it. These silicone ear tips are never any good. Foam tips have always led the way... Dekoni Bulletz, anyone?

These are good little earbuds that comfortably stay in my ear, but just be wary in what they are replacing. I used these on my Sony WF XM5 and they have significantly reduced the noise cancelling capability when compared to the stock earbud due to the material. It's not a fault of these earbuds, they are flawless in build quality and ear fit, and I would certainly reccomend them to anyone.

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.

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.

AFUL Performerシリーズ（Performer 8等）との組み合わせで愛用しています。同社のmithryl（ミスリル）とも比較しながら、本製品（W1）の真価をレビューします。 結論から言うと、どんな楽曲（ソース）でも安定して高音質を楽しみたいなら間違いなくW1がベストです。 ■ 物理構造と音響的なメリット 優れた高域ピークのコントロール：軸の設計と柔軟な素材特性により、音源に含まれる鋭い高音（サ行の刺さりやシンバルの過度な金属音）を適度に抑え込み、耳に優しい質感へ整えてくれます。 高い密着度による低域の安定：耳道に吸い付くようなフィット感により密閉度が上がり、抜けがちな低音の量感やレスポンスをしっかりと確保できます。 イヤホン単体で「高音が刺さらない」と評価されているモデルであっても、実際の刺さりは楽曲（ソース）側のマスタリングに依存します。W1はそのソース側のムラや過酷な高音成分を物理的に受け止めてくれるため、曲ごとの相性に悩まされることがなくなります。

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.

The SpinFit W1 offer a remarkable blend of comfort and performance. These ear tips fit snugly and securely, ensuring they won't fall off your ears during use. However, it's worth noting that their grippy nature may take a bit of time to get used to due to the initial stickiness. Once you settle in, though, the wearing experience is really comfortable with the right size. While the price tag may seem steep at $12.49 for one pair, the investment is justified by the exceptional quality and benefits they provide. The W-shaped design not only reduces pressure from the outside but also enhances noise isolation, resulting in an immersive listening experience. Moreover, the overall improvement in sound quality and comfort is noticeable from the moment you start using them. I really like them.
