- Omni for True Wireless Earbuds & IEMs - MS - Patented Silicone Eartips for Replacement (1 Pair) (3.7 mm Nozzle Dia.)

If you use wireless earbuds, you know the stock tips are often the weakest link. They might be too shallow, too slippery, or just plain uncomfortable. Enter the SpinFit Omni—and they are exactly the upgrade I was looking for. SpinFit's patented 3D axis design isn't a gimmick; the tips slightly swivel to match the unique curve of your ear canal. This results in an incredibly snug and comfortable fit that lasts for hours, which is perfect for my long work days. Crucially, that perfect seal means the passive noise isolation is immediately better, which in turn boosts the performance of the earbuds' ANC (Active Noise Cancellation) and, more importantly, the bass response. Everything sounds tighter and more impactful now. The big win for me was that I got them to fit on my Soundcore Liberty 4 NC earbuds. The stock tips felt a little shallow and sometimes broke the seal, but the Omni tips snapped onto the earbuds and still allowed the Liberty 4 NC to fit and charge perfectly inside its case. If you have similar issue with L4NC, grab a pair of Omnis—it’s an instant, noticeable sound quality and comfort improvement. They are a bit pricier than standard silicone tips, but considering the soundstage improvement, the non-irritating, soft material, and the secure fit they provide for me, they are absolutely worth the investment for any earbud user.

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 omni are compatible with my Alpha and Delta ks3 correctly. These have a shorter bore length. 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 S(11mmx7.6mm) 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 and time on these tips. They are worth the money because I have never felt this comfort before. Thank you spin fit! Sound: So this correlates to the seal of the tip. The better the seal to the ear the better the sound frequency It outputs. The style of tip can also change the overall frequency a bit. These are a standard bore so they do not change anything. But they increased the details on all fronts. tighter bass, clear mids, and detailed highs because the fit is so good for me. 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 really good. I replaced the stock eartips on my jabra 75t. It fit the iem very well and secure, even more secure than the stock tips. The fit was better, stays in the ear more, it prevents most slipping even though my ear creates a lot of wax. Again, I emphasize how secure these tips are, the stock tips of every single tws iem I use is not secure, but this omni fixes that issue almost completely. The stock eartips continuously slip no matter what I do. The omni is far better than stock and they sound just fine, no significant negative effects, I notice no difference really. The main negative I have with these is there is a lot of itch, at least when I first put them in. Even brand new, even after using 70% alcohol to clean them, doesn't matter what position or how deep or shallow, it itches. To be fair, my ear canal itches for just about all eartips, but it seems to be worse with these. Then after a while the itching subsides and it's normal again. These would be the bear eartips I've ever experienced if it wasn't for that one thing. Other than that, these are great.

I first started looking for new tips when I got a pair of cmf buds pro 2 and found them uncomfortable over long periods of time, I bought the nothing ear 3 after thinking it was just the shape of the bud and found them also uncomfortable and would make my ears hurt just to same. Tried every size of tip included and still no good. I saw a Reddit post saying to try spintip tips, found these on Amazon and found some reviews saying they wouldn't fit my earbuds because of their more rectangular tip shape. I can confirm these fit both the nothing ear 3 and the cmf buds pro 2, the fit is very tight but even tighter on the cmf buds as its rectangular shape is a bit larger than the nothing ears but they do fit with some effort and it being so tight isn't a bad thing because they're definitely not going to come off on their own or get stuck in your ear. These spinfit tips are very nice, the silicone is soft to the touch unlike any other tip I've ever felt before and it actually has some directional give to form better to ones ear. Just trying them out I would say they are far more comfortable than stock tips but I'll update my review after a couple weeks after I've seen how they hold up. I wear earbuds for about 10 hours a day in a loud warehouse environment and that will be the true test to whether I finally found a solution to my ear fatigue and pain from wearing earbuds. Update 12/21/25: These are definitely worth the steep price, turned my uncomfortable earbuds into ones i can wear for 10 hours straight. Already ordered a second pair for another set of earbuds.

So they are good, don't get me wrong. They fit a little tight onto my kiwi ears cadenza earbuds but they do fit.... However they are still somehow too tight for my ears (i got the ss). Well they are too tight for my right ear, they fit okay in my left. They work fine until i smile (or if it's cold out) then the right one makes a groaning sound and pops out of my head just enough to break the seal. Honestly it's just a me problem, it would probably help if they were deeper (they seem kinda shallow.) When they seal properly they do grip pretty good though!

They will work with the nothing ear 2024, but takes a little work getting them on. The Spinfit Omni are really great, and comfortable on the skin. One of my gripes with the Nothing Ear 2024, was the stock ear tips bothering the skin in my ears. Spinfit Omni fixes that, as their great on the skin. Then I always wear a L sized tip for my ears, and these fit my ears nice, but it is a little more tighter feeling over my stocks tips. Thing is they feel like they nicely mold inside my ears. As for changing the sound signature, my earbuds feel little more immersive now, and not as lose with the audio (sorry don't know exact terms). Great buy, great on the skin... Now I like to buy a pair for my Hexas.

While they stay on the ear better than the original, the bass is significantly less due to their greater distance from the ear canal. I forgot to mention, the added silicon stops the contact with the charging box, that means they don't charge.

I own and have owned Sony WF-1000XM5 and Sony WF-1000XM4 that bring the foam earbuds. These are 10 times better and have a perfect seal and comfortable when you buy the right size. Fully recommended
