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

After trying several different kinds of tips, these are by far the best. 5-stars for an awesome comfortable fit and the sound quality enhancement they produce is exactly what I needed.What sold me... I have Soundcore X20 sport earbuds that I use as my daily drivers. I'm outside and sweating a lot, they have proven to be perfect for my uses. But they have a baked in bass-heavy sound signature, and although adjusting EQ settings does help reduce the muddy/boomy sound they produce with their stock silicone tips, it still does not completely get rid of it. With these tips installed, however, bass frequencies are cleaned up immensely and the boominess is absolutely gone. They actually do such a great job at bass retention that I can now bring the bass/mid-bass EQ settings up from zero. Which is fantastic, because they are now within the tunable EQ range provided by the Soundcore app.Bass is now very clean and tight (think sealed acoustic suspension woofer), soundstage has increased noticeably, instrument separation has improved, and the rest of the audio spectrum is clear and crisp. They are so comfortable, making them very pleasant to listen to for long sessions. The only downside is that the X20's will not fit into their charging case without removing the W1 tips first. But for me, this is well worth it the small inconvenience.I highly recommend these, especially if you have bass-heavy IEM's like the Soundcore X20 Sport, or any other IEM for that matter.TIP: I recommend also trying the next size smaller tips than you would normally purchase. I tried all four sizes, and they ALL fit my ears good enough to provide a nice, comfortable seal and great sound. This, to me, was VERY impressive. I normally use the M size, and they fit fantastic, however I found the MS size to also fit my ears with maybe just a little more comfort. S was just a slightly loose fit, L was just a slightly tight fit. I kept both M and MS tips in my collection; I use the slightly more secure-fitting M tips outdoors while active/working/sweating and use the MS size for indoor/casual listening, as they are slightly more comfortable with less pressure in my ear canals.These are fantastic tips, such a great product. Easy 5-stars.

I recently purchased the SpinFit W1 for IEM ear tips, and I couldn't be happier with my decision. These ear tips are crafted from patented medical-grade silicone, which not only ensures durability but also provides exceptional comfort for extended listening sessions.The double W-shaped tube core design is a game-changer. It offers more stability, ensuring that the ear tips stay securely in place, even during vigorous activities. This feature is particularly beneficial for those who use IEMs while exercising or commuting.What truly sets the SpinFit W1 apart is the improved sound quality. The snug fit creates an excellent seal, enhancing bass response and overall audio clarity. I noticed a significant difference in the soundstage and detail compared to my previous ear tips.In summary, if you're looking for ear tips that offer comfort, stability, and superior sound quality, the SpinFit W1 is an excellent choice. Highly recommended for audiophiles and casual listeners alike!

I use this with my Sigmond Supermix 4s, amazing. Worth every penny.I use them to game, and use them for hours on end, and they are comfortable for those long sessions.

From my short time with them i can say the feel realy nice in my ears. Fits well and deliver a great sound

I was super skeptical about spending $10 on a single pair of IEM sleeves but I was not disappointed. They stay well seated compared to every other silicone sleeve I've tried. I've worn them for hours with no problems whatsoever. The comfort is tremendous and they bring out the best in every IEM I've fitted them to.Of course, they don't provide the same noise isolation as, say, Comply foam tips, but that comes with the territory.One last thing, these are the first silicone sleeves I've used that don't seem to cause a big pressure change on insertion and extraction. I've got really sensitive ears that usually hurt when I remove other silicone sleeves, but I've experienced none of that with the Spinfit W1s. I'm not sure if they're vented or what, but for me, it makes a huge difference when I need to remove them frequently at work.It's too soon to guage the durability but if they last even a couple of months, I'll keep buying them.

Replaced the tips on a Hidizs MP143, and they finally have a good ear seal. No problems with the sound either.

These replacement ear tips fit and feel good in the ear. Have purchased 3 sets in total since trying them. They are comfortable for long periods with them in.

These ear tips have a nice material but they would constantly either fall off after an hour of wear (getting warm in the ear) or the tip would get stuck in the ear. I could never find a middle ground with them.Additionally, I tried them with another earbud I own (L4NC soundcore) and they fit as some said they would but the same exact issues would occur.
