These completely changed my experience with gaming IEMs. I was struggling with comfort, fit, and long-session usability on my gaming earbuds. The stock tips worked, but I was constantly aware of them in my ears and never felt like I had the perfect seal. The SpinFit tips immediately improved both comfort and fit. The seal was excellent, which helped maintain audio quality and positional detail while also making the earbuds feel more secure. Long gaming sessions became noticeably more comfortable, and I spent far less time adjusting the earbuds. What impressed me most was that they solved a problem I initially thought was caused by the earbuds themselves. Once installed, they significantly improved the overall experience and made the earbuds feel like a different product. Pros: * Outstanding seal * Excellent comfort * Improved long-session usability * Better fit than stock tips * Maintained excellent audio performance Cons: * Sizing can be confusing when ordering * Installation can be tight initially If you’re having comfort or fit issues with your IEMs, these are absolutely worth trying before giving up on them. They turned out to be one of the best upgrades I purchased.

I Have large ear canals and never knew it, I always wondered what all the hype about ANC earbuds because I thought they were just Meh at best. I never understood what the "seal" meant as I never had a pair that I got a seal on. Then by mistake one day I got a temporary seal on some air pods and wow what a monumental difference it was. Unfortunately I'm and Android user and while the air pods are nice they don't work the best with android and I'm not a fan of the stem or the fact that they are white and they have horrible PC BT lag. Unlike the SONY that works with FlooGoo for 20MS gaming latency. I spent a huge amount of time and all they hype about foam this hybrid foam that silicon warm wet gel etc... None of that matters at all, I mean 0 zero if you don't have a seal, ANC does not work. You could have a three foot foam hybrid wet gel with extra foamy foam but if it does not create an air tight seal in your ear canal it is all for nothing. This is the first brand that I found that actually makes and extra large and it worked! I got a seal on my left ear with their extra large tips. I was in the process of returning the new SONY WF-XM6. I just spent over 300.00 put the largest foam tip end spent 45 minutes twisting, pinching and squishing with zero results. I told the wife to hold off as I wanted to try one more pair of tips and they actually worked. I will end in saying two things, if ANC earbuds have never impressed you its probably that your like me and never got a good seal. Second I wish there were more manufactures that would make extra large it should not be this difficult to find. Third I wish they were cheaper or gave you more than one pair but I guess when you are one of the only ones that has a "Real" XL you charge a bit more. I also want to say thanks to a reviewer on here that made a fantastic review on the XL and his beats, that review got me to spend the 20 bucks and hold off on the Xm6 returns.

I bought these for my OnePlus Buds 4 (they were pretty difficult to get on, but it is possible), after hearing tales of how nice these eartips are and being more comfortable... It's definitely overhyped. Sound-wise, negligible at best (obviously, there are way more important things if you want to change sound signature) as expected. But the comfort arguments are really overstated in my opinion. It IS a tiny bit more comfortable but nothing I'm jumping to recommend to all of my friends or anything. So basically, believe it or not, these are just eartips. I'd recommend them IF you have lost your original ones and need a replacement since these are nice, but unless you're seeking every tiny improvement regardless of price then these probably aren't worth picking up for the average person. Additionally, for the OPB4, the case no longer snaps shut with the earbuds inside of them. It charges, but there's gotta be like a milimeter of clearance stopping it from completely closing but it's basically closed regardless. Just worth noting, I saw someone else mention it but they had the XL size and I thought the MS would probably fit, but not quite!

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.

These keep my earbuds in my ear! Foam ones are very uncomfortable and the normal ones somehow always slip out. I move around a lot and these automatically adjust depending on what you're doing! I'm not sure how they work exactly but it's incredible!

Frustration of PBP2 unique and nozzle design which has made difficult to find a perfect match for ear buds tips a challenge. However, I was determined to make the Omnis work, I forced flipping the silicone umbrella inside out before pushing the core onto the nozzle. It gave me a better grip to force the core over the lip to secure the ear bud. The fit was solid and secure, the compression in the ear feels real good. But...not all was well! Changing the tips and listening to my favorite song, definitely felt the acoustic change, I felt the music lost its dynamic and sounded compressed. I am thinking this might be because I forced the tip to secure over the unique nozzle design and could have compromised the sound. I am not not an audiophile and I could tell the difference in acoustic, it didn't feel the same as original tips. I am going to try for few days before I change it back. If I was looking for perfect fit. Maybe these are not meant for latest PBP2.

My earbuds have the tendency of slipping out of my ears randomly even when just lounging around but especially when exercising. I've tried different tips that came with the earbuds but none solved the problem. I was resigned to just accept that my ear shape was not suitable for earbuds. That is until I came across these SpinFits. Now, the earbuds stay in place! I took these to the gym and they did not slip out. My buds not maintain their seal. This review is only after about two days of use, but these appear promising. I have the Google Pixel Buds Pro 2 and the installation of the SpinFits was difficult. When you look at the tips and the shape of the earbuds, it seems like the SpinFit will not fit. However, I suggest you place one edge of the bud into the tip and slowly rotate the bud while applying force on the tip to get it over the bud. Be patient. So far I am happy with these eartips, I no longer have to fear that my buds will fall out during a run. I wish I would've gotten these sooner.

These are the only ear tips I've found that fits my ear - which is surprisingly hard to find. If I was judging only on fit they'd get a 4/5 - mostly work, pop out of the ear sometimes if I'm exercising. However, if you have sensitive ears be aware - these may note be silicone. I get contact dermatitis with rubber/latex and after a few weeks of wearing these my ears ache. Switching back to the OEM tips (Sony) makes that pain go away, so I can only assume these tips are rubber or latex. I tried confirming their claim of "certified by SGS after passing the OECD 439 Reconstructed Human Epidermis (RhE) test (Report No. PUG23800708). " but the SGS website won't load their report number, so that's not great either. They're a great product if you don't have allergies - but beware if you do, and take advantage of Amazon's return policy.
