It’s the groove in the inner bore that makes the difference: it grips the lip of the nozzle much better than the usual smooth eartips and this provides better comfort, as the tip is more stable, while also providing a more uniform sound quality across earphones: the distance between the sound port and the end of the eartips is constant, so you get the optimal distance that SpinFit found. Speaking of sound, I find the CP500 to be neutral as they don’t modify the sound significantly – for better or for worse. The Spinfit CP-100 is probably the most popular Spinfit eartips around. They are also the most widely available one. The original CP-100 model had a fairly stiff, color-coded stem (with color changing upon size) and the outer material was also fairly stiff. This model suited a number of IEMs especially those with a shallow nozzle (e.g. Dunu Luna, pictured below). The CP-100 was pretty much a utilitarian eartip, as in it would suit most models without affecting the FR too much or causing discomfort. I personally found the surface of the tip to be somewhat itchy after long-term use, and the stiffer outer layer didn’t have the best grip with the inner-ear wall. Fitting earphone nozzles: the first problem for the novice is – and it certainly was for me – to find the right SpinFit model to fit a particular earphone. First, one has to select the right diameter of the inner stem so that the SpinFit is being held safely in place. As a rule of thumb, most earphones have a nozzle diameter of 4.5 mm so that the CP145 is the most universal model for initial tip rolling.
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. Final Thoughts The SpinFit CP100 are the basic model, which by shape and feel most closely resemble “standard” eartips. They are conical (a wide ogive, to be exact) and offer a diameter of 4 mm which fits most earphones (including the Campfire Audio Vega 2020 and Dorado 2020, the Thieaudio Legacy 4, the Tin HiFi T2), but which is also a bit tight for earphones with larger nozzles. Still, they’re the ones that will probably fit the larger number of earphones, as they do just fine even with those that have a smaller nozzle like the Legacy 4. They come in 5 different sizes: SS (XS would have probably been better), S, M, L and XL. They are equivalent to the CP100 in every respect, except for sound: the new material makes treble a bit stronger overall. SpinFit CP145mm longer than CP-100 and CP-145, the additional length and bullet-shaped caps of the CP-155 allow deeper insertion to bring more bass and fuller vocal. The basic idea underlying every SpinFit eartip model is the following: traditional eartips have a straight solid core at their centre which stays so independently of the actual shape of the ear, but it would be better if the core could bend and follow the curves of the ear canal. This is what happens with the SpinFit tips: there is a point in which the silicone is thinner and therefore softer and it’s shaped like a doughnut, so that it can bend and provide better comfort.
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. 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. For neutral tonality with emphasis in bass, midrange and vocal. For clarity and bigger soundstage, choose CP-240.The SpinFit CP1025 were made to fit the Apple AirPods Pro thanks to an included adapter. The adapter is in fact an add-on that you can ignore completely if you use other earphones, and the CP1025 work just as well. In fact I think SpinFit should market this model not just for AirPods Pro as it – surprisingly – is also the one that I found to work best with other TWS as well, even more than the CP360. Update: SpinFit has actually done so, making the CP1025 available without the adapter and as more general TWS eartips. The CP1025 have an inner diameter of 3.6 mm and an outer diameter of 12 mm, with a height of 6.7 mm. There are four sizes available: L, ML, M and S. The trebles on the EM6L are really well extended. They are very airy and detailed. However, the detailed trebles come with their cons too. As such, the EM6L is a bit sibilant. It also doesn't compare to the Xenns Top, which has very well extended, extremely detailed, and quality trebles but presents them in a controlled and smooth manner. Hence, it is not fatiguing or overwhelming during long sessions. The Top also has better technicality and separations than the EM6L or the Khan by a huge margin (understandably as they belong in different price ratios). So the trebles sound better on the Xenns Top. The EM6L sometimes sounds fatiguing and piercing with treble-heavy songs.
