Each pack includes 2 pairs, making them the go-to upgrade for premium in-ear audio experiences. ## Description Product Description Ergonomically designed with the ability to spin in all directions and customized fit your ear canals. 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. Warm Reminder from SpinFit Fitting and wearing experiences can VARY because we are all unique creatures! Please make sure you get the right model and the right size before placing your order! Review: Perfect for FIIO FH5 - Been looking for suitable tips for my FIIO FH5’s. Using Inairs on my Shure SE215 which are perfect for those. Didn’t work at all for me on the Fiio’s. Felt like they were jammed in my ear and effected the sound, lots of low end but dulled the mids / highs. Similar experience with Comply tips on the Fiio’s too. Tried the Spinfit 155 (medium) which gave a lovely balanced sound, to my ear anyway. They were just a little loose on the nozzle and a tad too long which irritated my ear canals after a while. The Spinfit 145 (medium) are perfect. Snug fit on the nozzle, good seal in the ear canal and used for hours with total comfort. They give the earpieces a better, secure fit than the supplied tips from FIIO. Lovely low end thump but with all the clarity the FH5’s possess. For me the 145’s are a perfect match with the FH5’s. Very subjective I know, but hopefully helpful for anyone looking for suitable tips. Review: Alright, if expensive - Bought these to replace the generic tips on my IEMs after I lost one. I am not an audiophile or ultra particular about my music, but I do appreciate good sound. I never had a problem with the default tips included on my IEMs but these have distinctly more mids and less bass in comparison. Not necessarily a good or bad thing depending on your listening preference. They seal just as well and are just as comfortable in my ears as the default tips, but are harder to clean due to the ridge in the center hole if your ears are prone to wax buildup. I didn't have a problem with my default tips, and its nice that you get two sets, but I don't think it is worth the extra cost over generic tips. ## Features - Eartip has a bore size of 4.5 mm which fits earphones that have sound port nozzle 5-6mm. (Mostly w/ BA drivers) Comparable to Comply T-500. - Compatible with AKG N30, AKG N40, and 1More E1001 Triple Driver - Included in the box for AKG N5005. - Package includes 2 pairs of silicone replacement eartips ( 4 pieces ). ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07BPYTS7N | | Best Sellers Rank | 3,576 in Headphone Earpads | | Brand | SpinFit | | Brand Name | SpinFit | | Colour | Sky Blue | | Compatible Devices | Headphones with sound aperture of 5-6 mm | | Compatible Headphone Models | 1MORE Triple Driver, AKG N30, AKG N40, KZ ED16, KZ ES4, KZ ZS5, KZ ZS6, KZ ZSA, Sony WF-1000X | | Compatible devices | Headphones with sound aperture of 5-6 mm | | Customer Reviews | 4.2 out of 5 stars 6,153 Reviews | | Enclosure Material | Silicone | | Global Trade Identification Number | 04713037521474 | | Item Dimensions | 15.2 x 5.3 x 1.8 centimetres | | Item Weight | 0.3 Ounces | | Item dimensions L x W x H | 15.2 x 5.3 x 1.8 centimetres | | Manufacturer | SpinFit | | Manufacturer Part Number | CP145-M | | Material | Silicone | | Model Number | CP145-M | | Number of items | 4 | ## Product Details - **Brand:** SpinFit - **Colour:** Sky Blue - **Compatible devices:** Headphones with sound aperture of 5-6 mm - **Item dimensions L x W x H:** 15.2 x 5.3 x 1.8 centimetres - **Material:** Silicone ## Images ![SpinFit CP145-M - Silicone Eartips Replacement for Universal IEM Earphones - 2 Pairs - 4.5mm Nozzle Diameter (Medium) - Image 1](https://m.media-amazon.com/images/I/61QgIzqvFiL.jpg) ![SpinFit CP145-M - Silicone Eartips Replacement for Universal IEM Earphones - 2 Pairs - 4.5mm Nozzle Diameter (Medium) - Image 2](https://m.media-amazon.com/images/I/61Rp9BDncDL.jpg) ![SpinFit CP145-M - Silicone Eartips Replacement for Universal IEM Earphones - 2 Pairs - 4.5mm Nozzle Diameter (Medium) - Image 3](https://m.media-amazon.com/images/I/61emV6xF3WL.jpg) ![SpinFit CP145-M - Silicone Eartips Replacement for Universal IEM Earphones - 2 Pairs - 4.5mm Nozzle Diameter (Medium) - Image 4](https://m.media-amazon.com/images/I/610kuyMoVwL.jpg) ![SpinFit CP145-M - Silicone Eartips Replacement for Universal IEM Earphones - 2 Pairs - 4.5mm Nozzle Diameter (Medium) - Image 5](https://m.media-amazon.com/images/I/61i-4r1VM4L.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect for FIIO FH5 *by L***B on 4 March 2021* Been looking for suitable tips for my FIIO FH5’s.

I get a lot of ear infections and my right ear especially swells inside and can be uncomfortable. I read about these tips on Reddit and wanted to give them a try. I put them in and amazingly I got a seal and a comfortable fit in one hit. The sound is crisp and clear but now I also have the feeling of not knowing I'm wearing the IEMs at all. I'm sold straight away, I can't speak for durability but I have 2 sets, they look like they will stand the test of time.
