Better than stock earbud tips - 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. Review: These eartips were life changing - I loved my Beats Fit Pro earbuds because they had great sound and fit securely and comfortably. They are, without question, the best-fitting and sounding earbuds I've used. The only problem with them was that out of the box, they wouldn’t pass the Beats app fit test using any of the ear tips that came with the earbuds. So, I tried others. Comply TW-200-C Memory Foam Earbud Tips came highly recommended. I tried them with no luck. Same with several sizes of SpinFit CP1025-Silicone Ear Tips . Then, AI suggested that I try SpinFit Omni for True Wireless Earbuds in size XL. I got some, put them on the Beats earbuds, put the earbuds in my ears, and the world went silent. I'm talking Bose-level ANC. The bass response was also amazing. The layering of sound from the timbales at the start of Hotel California can almost take your breath away. And all this while the earbuds remained comfortable and continued to fit securely. (And the buds still fit in their charging case without any problems.) Now, when I'm at the gym, I can work out without any background noise. And I can hear what's being played a lot better. Used to be I had the volume turned up almost all the way. Now, it's at about 50% on the gym floor and maybe 60% on the hydromassage bed. Thanks to the effectiveness of the SpinFit eartips, these these Beats earbuds have replaced my JBuds Sport ANC 4 Earbuds that I had been using at the gym, my Soundcore Space One Headphones that I used on planes and trains, and my Soundcore Space A40 Earbuds that I took on trips of use on the beach or poolside. In fairness, I think most people, those of you with normal ears, will have the same end result with the included eartips. However, if not, it's worth the effort to try something aftermarket; a good place to start is with SpinFit. ## Features - SpinFit patented spinnable 3D axis that bends to fit unique ear canals' angle like customized.

I first tried them with a regular pair of earbuds (Soundcore Liberty Air 2 Pro) and they fit without any issues. They were extremely comfortable and fit my ears perfectly. However, I specifically bought them for my Soundcore Sleep A30 earbuds. Because those are designed to be worn while sleeping, they're very low-profile. These eartips would have been perfect for them, since they're also small and short. But unfortunately it was almost impossible to get them onto the earbuds at all. There are other low-profile eartips that aren't nearly as restrictive. For example, brands like Whizzer and KBear make eartips that are actually even smaller than these, but they fit a wider variety of earbuds thanks to their openings being wider. I own a pear of KBear coffee eartips, and they fit my A30's without any issues at all. But it's just unfortunate, because the quality of these SpinFit tips are unreal, and I also find them to be more comfortable than any other silicone eartips I've tried. These would have been perfect to wear with my sleep earbuds, but they just don't fit. I really wish SpinFit made a version of these with a larger opening to accommodate a wider range of earbuds. They do make other eartips with larger openings, but none are as low-profile as these. So while I think these are excellent, it's hard to recommend them when they can't fit a wide range of earbuds. ## Frequently Bought Together - SpinFit Omni for True Wireless Earbuds & IEMs - MS - Patented Silicone Eartips for Replacement (1 Pair) (3.7 mm Nozzle Dia.) - SpinFit W1 for IEM - MS - Patented Medical-Grade Silicone Ear Tips, Double W-Shaped Tube Core, More Stability --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/587386413-spinfit-omni-for-true-wireless-earbuds-and-iems-ms-patented](https://www.desertcart.us/products/587386413-spinfit-omni-for-true-wireless-earbuds-and-iems-ms-patented) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-04-26*
