Soundwise they are also quite close to the CP100, so they have very little impact (if any) on the sound and allow you to hear it as intended by the manufacturer of the earphones. The mids are clean and uncolored, but I still prefer the mids from the Xenns Top because of its technical abilities, clarity, and control. When compared to the Khan, I prefer the Khan's mids because of the dynamic driver tonalities. Both the Xenns Top and the Simgot EM6L have a balanced armature tone to them. The CP240 has a wide bore and fits comfortably on larger nozzles, but it also comes with a selection of adapters that allow it to fit snugly on smaller nozzles as well. CP360 and CP1025 It’s not only a matter of comfort: the CP145 prove to be great at passive isolation as well. As they seal off the ear canal quite well, the side effect is also that there is an almost-perfect level of isolation. Although the overall isolation is of course dependent on the earphones as well, these eartips make a real difference and shut most of the noise out. SpinFit CP155

The SpinFit CP360 are the first tips SpinFit developed specifically for “true wireless” earphones: they’re much shorter than the others because they need to fit in the cases, which often offer very little space for eartips. This means they can’t count on the depth of the insertion to give you isolation and have instead to rely on width: the ear canal is larger at the entrance and so these eartips need to be wider to seal it. In fact these are among the few SpinFit models to offer an XL size (on top of L, M, S and SS) and that’s because of this. The L size is 13 mm in width and 8.5 mm in height, while the XL is even larger at 14 mm wide and 8.5 mm high. They are basically shorter CP100! That’s also true when you look at their shape, which is similar but more compact. The inner diameter is 3.6 mm.Everything else is the same as on “normal” silicone eartips, which is also why the SpinFit tips are so great: you get all the pros (good isolation, washability and basically eternal durability, wide compatibility) with none of the cons.

The wearing experience is very similar to the CP145, but due to the additional stiffness they can feel a bit more fatiguing during long runs. While the dome is made of the same silicone, the different inner bore has a small impact on comfort. Let’s look at the different SpinFit models, and compare how they fit on a selection of IEMs. Note that the sizing within each model (Small, Medium, Large) only affects the width of the flange and how that fits your ear, and does not affect the size of the bore or how well they will fit on different IEMs. CP100/CP100+ The SpinFit CP100+ (or CP100 Plus) are the exact same as the CP100 in terms of size, but they are made with a different material. They keep the same diameter of 4 mm and the same variety of sizes (SS, S, M, L, XL), but they are made of medical-grade silicone and feature more subdued colours and a more transparent dome. Among the rest, the CP-360 should be in your stable if you’re into TWS earphones, they are one of the few TWS-specific eartip after all. The CP-500 is a specialist eartip that can be unpredictable, and being the widest-bore tip in Spinfit’s lineup offers something unique. Finally, the CP-240 is something I couldn’t find a use for and the CP-800 didn’t perform as well as the tips it’s supposed to replace (for me). So these two don’t excite me as much.I also noticed that the EM6L is quite dependent on the source material and the DAC amp connected to it. When I connect it with my Moondrop Moonriver 2 Ti, the mids and trebles are a bit smoother and more forgiving. Whereas with my Fiio Q3, songs with bad recordings or sibilant sounds come through as such. With the Xenns Top, either connected with Moonriver 2 Ti or Fiio Q3, songs with bad recording or sibilant in nature do not sound as bad as they are. W1 offers a similar fit to CP145, but updated materials and design to generate less pressure inside the ear while delivering a secure fit and seal. When I started using in-ear headphones, around a decade ago, one of the things that I didn’t like about the experience was the eartips. They were just too uncomfortable compared to classic earbuds with foams. Sure, they provided better isolation, but having very sensitive skin I often found myself with irritated ears. Then I discovered foam eartips and that changed things completely, as they were much more comfortable, as isolating as the silicone ones and less prone to cause irritation. So I basically stopped using silicone tips – why bother when the foam ones were so much better for me? But one of the realities of life is that things change, sometimes for the worse and (thankfully) sometimes for the better, and man did my perception of silicone tips change when I discovered the SpinFit tips.
