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. The SpinFit CP145 are much like the CP100, but they have a smaller top so they go better inside the ear. The difference is not dramatic in terms of size, but the fit is quite different. The general shape is again ogival, with a height of of 10.1 mm and a with of 13.5 mm. With an inner diameter of 4.5 mm, the CP145 can fit earphones with nozzles up to 5.5/6 mm in diameter: that means that even IEMs with larger soundports, like the Tin HiFi P2, Shanling ME500 Platinum, Fearless Audio S10 Genie or Moondrop A8 will fit correctly, though the silicone will stretch a bit. There are just three sizes: S, M and L. Eartips of the different makes are rather complementary and listeners have to acquire a box full of different types before “tip rolling” to find the best sound appeal for their individual ear canal geometry. So third-party eartips companies must be the best of friends. These eartips are meant for true wireless earpieces. If you find SpinFit CP-350 too short, this one fits between regular CP-145 and CP-350. Bass and low-mids are stronger than CP-350. Vocal is forward with good clarity. 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.
Soundwise, the CP155 are neutral and I can’t hear significant differences when compared to the CP100. If anything, the better seal allows bass to get further down, but it’s a minimal difference which is highly dependent on the earphones you are listening to. SpinFit CP240 The main difference between the W1 and the other eartips by SpinFit is the dual-density silicone used to make the inner bore. It has a wave shape, hence the name. This makes the inner bore stiffer, plus it also makes it easier for it to grip earphones’ nozzles and therefore offers more stability. It is therefore advised to use the W1 for especially large and heavy earphones, as it will be difficult for the tips to come off. As a last bit, the silicone is actually medical grade, so the added benefit is you shouldn’t have issues with allergies and other adverse reactions. SpinFit CP500
The vocal presentation is very clean, but male vocals sound a bit thin to my ears. However, female vocals are really enjoyable on the EM6L. In fact, I would say that female vocals sound even better on this than on the Xenns Top. Exceptional clarity with good treble extension. Soundstage is one of the biggest I have heard. Vocal presentation is forward. Can get sibilant when matched with bright earphones. CP360 and CP1025 are designed for TWS earphones. CP360 is designed to provide a deeper fit, while CP1025 is more shallow. While both will fit on most TWS earphones, some charging cases may not be compatible with the CP360. CP1025 is also available with adapters for Apple AirPods Pro and Samsung Galaxy Buds Pro. W1 The CP240 is a double flange eartip. Double flange eartips are useful for listeners who have larger ear canals and have a hard time getting a good seal. They can also provide improved isolation in general. On the CP240, the SpinFit pivot comes in between the first and second flange, to provide flexibility at the top for the second flange. In this round-up, we shall explore how well this mechanism works across a variety of IEMs. Models to be evaluated: Spinfit CP-100, CP-100+, CP-145, CP-145 (medical-grade silicone), CP-240, CP-360, CP-500, and the CP-800. The only two in-production models that I don’t have with me are the CP-155 (I don’t have a large-nozzle IEM at the moment) and the Airpod-specific CP-1025 (I don’t have an Airpod). With that out of the way, let’s head right in.
In this review, I will be discussing the Simgot EM6L, comparing it with the Xenns Mangird Top and QKZ HBB Khan. I have tested the EM6L using the Moondrop Moonriver 2 Ti and Fiio Q3 Dac Amp. 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 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 main differences with the CP360 are the height and the radius: the CP1025 are shorter and slightly narrower (12 x 6.7 mm vs 13 x 8.5 mm), so they don’t go all the way inside the ear canal but manage to seal it effectively thanks to their wide radius. This also means that they fit most charging cases better, as they are shorter.A small note: I am going to compare the various eartips using the “L” size as reference, so you will need adjust that to the size you are interested in as the purpose is to give you a frame for comparison, not to describe every possible size and combination. Passive isolation is quite good, too: probably due to the relatively deep insertion and wide dome, the SpinFit W1 are quite successful at sealing off the ear canal and therefore offer great isolation.
