CP145 has undergone various adjustments in shape and material. This model is a model that would never disappoint you. CP145 grabs the treble well and keeps the flexibility of the bass. Perfectly for audiophiles. Among all the SpinFit models, CP145 is the model that has been most often chosen to be the "IN-BOX" collaboration model. CP145 is rather longer than other models which makes it go deeper into the ear canals. Of course the patented design allows them to swirl and perfectly adapt to your ear canal structure. Plus I believe you'll find how the sound performance has been updated if you search SpinFit CP145 on the Internet. If you would like to enjoy the perfect fit and top sound performance with your IEMs, CP145 is the must-buy model! Which Size? The different size ear tips accommodate different ear canals. Choosing the proper size is critical for a secure, comfortable, and quality result. If you’re unsure, medium size fits most users comfortably. The Design SpinFit has an ergonomic concave design at the core to allow the ear tip to swivel, making it flexible to bend and twist to the contour of a person's ear canal. SpinFit ear tip is able to be inserted deeper into the ear canal, enabling less obstruction along the sound field dispersion path, which results in greater audio experience while providing maximum comfort. The Feature Enhanced Noise Isolation - Consistent optimal seal even for headphones with an awkward insertion angle, allowing increased noise isolation. Frequency Extension - Enhancement on treble and bass ensures a superior listening experience to the foam and the stock ear tips. Superior Comfort - Premium soft silicone material along with the ergonomic design provides outstanding and lasting comfort. Patented 3D Axis - Patented cushion makes them unique and perfect replacement for your stock ear tips.

Review: It now all makes sense - I have numerous pairs if IEM's, with my favourites being the FIIO FG3, Meze Alba and 7Hz Timeless I haven't used any of them for a few months after getting tired of almost having to screw them into my ears + hold them in place to hear anything like those IEMs can deliver Not any more! These SpinFit fit perfectly on all 3 pairs and the sound, wow! They create a perfect seal, which delivers stunning bass and high end clarity. I also now know why the 3 pairs are rated highly - I keep swapping one to another to another These little tips have completely brought my IEMs to life, and I couldn't be happier. They very comfortable too I have (what I think are) 'normal ears - ordered these in a L after being told a size larger has more chance of creating a good seal I also want to add I have spent maybe Β£120+ trying all different types and sizes of tips and these were my last shot The only thing I struggle with is how these little tips can make such a huge difference in sound quality As regards the price - compared to your IEMs they're probably a fraction of the price, but they squeeze every last bit of sound from them, and saves you doing what I did ... waste money on cheaper ones that simply don't perform I highly recommend them Review: Fit letshouer S12 pros - I'm glad these come in packs of 4, they lasted about 3 months of daily wear before the elastic that bands them to the IEM started wearing and you get these stuck in your ears. As such, giving 4 stars as I would have hoped they would last longer. A reassuringly tight fit to the letshouer S12 pros to begin with and better sounding, imo , than the stock offerings. They fit my ears well, block out enough sound of the gym's questionable playlists -so work for me. I'll keep buying them. ## Features - Core diameter 4.5mm.

I'll keep buying them. ### ⭐⭐⭐⭐⭐ The best eartips I've ever tried *by C***T on 3 July 2024* Used stock tips for the KZ ZS10 Pro X for some time now, nah, I don't like those. Then I came across these and oh my, aren't they amazing. I'm getting a much better seal with these and they actually make the audio really stand out in terms of bass, mids and treble, it balances them out a little bit more, making a more neutral signature, which I really like. When I am using them, I literally have no idea I have them in my ears, yes they are that comfortable. When I got used to them they sat in my ears like a charm. They are now the most comfortable things I have ever worn with my IEM. I was recommended these by another person who uses the KZ ZS10 Pro X and it made me really want to get them, so I did and I couldn't be happier with my purchase. Thank you for making such an amazing product. ## Frequently Bought Together - SpinFit CP145 for IEM - L - Patented Silicone Eartips for Replacement, Secure Fit and Supreme Comfort (2 Pairs) (for Nozzle Diameter from 5-6mm) - SpinFit W1 for IEM - L - Patented Medical-Grade Silicone Ear Tips, Double W-Shaped Tube Core, More Stability - SpinFit CP155 for Wide and Long IEM Nozzle - L - Patented Silicone Eartips for Replacement (2 Pairs) (for Nozzle Diameter from 6-7mm) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kr/products/129001492-cp145-for-iem-l-patented-silicone-eartips-for-replacement-secure](https://www.desertcart.kr/products/129001492-cp145-for-iem-l-patented-silicone-eartips-for-replacement-secure) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-08-07*
