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 £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: The best eartips I've ever tried - 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.

### ⭐⭐⭐⭐ Fit letshouer S12 pros
*by E***E on 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.
