SpinFit CP145-L patented silicone eartips deliver a secure, comfortable fit for earphones with 5-6mm nozzles.

## Description

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!
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.
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.

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!

## Customer Reviews

### ⭐⭐⭐⭐⭐ It now all makes sense
*by  on Reviewed in the United Kingdom 25 November 2025*

I have numerous pairs if IEM's, with my favourites being the FIIO FG3, Meze Alba and 7Hz TimelessI 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 deliverNot 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 anotherThese little tips have completely brought my IEMs to life, and I couldn't be happier. They very comfortable tooI 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 sealI also want to add I have spent maybe £120+ trying all different types and sizes of tips and these were my last shotThe only thing I struggle with is how these little tips can make such a huge difference in sound qualityAs 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 performI highly recommend them

### ⭐⭐⭐⭐⭐ Good insulation and less heat
*by  on Reviewed in the United Kingdom 21 October 2026*

I really liked these. They solved my problem with ears overheating and also provide a better fit on top.

### ⭐⭐⭐⭐ Fit letshouer S12 pros
*by  on Reviewed in the United Kingdom 1 January 2026*

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.
