They’re quite comfortable and in fact I find them to be slightly more comfortable than the CP100, because they fit more snugly in my ears. They’re the closest equivalent I have found among silicone tips to the sensation foam eartips give me: that my ear canal is sealed by something that fits snugly in it while respecting its shape and boundaries. In other words, it doesn’t feel like something that gets inside my ears while trying to impose its presence, asking my ear canal to adapt to it, but it feels like something that fits in the canal trying to take the space in there and nothing more. It’s a weird sensation that’s very difficult to describe, but I hope I somehow gave you an idea.

Optimal seal– Consistent optimal seal even for headphones with an awkward insertion angle, allowing increased noise isolation. They are equivalent to the CP100 in every respect, except for sound: the new material makes treble a bit stronger overall. SpinFit CP145 This warranty extends only to personal use & does not extend to any product that has been used for commercial use, rental use, or use that is not intended. There are no warranties other than expressly set forth herein. 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.

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. As they get the deepest inside the ears, the CP155 are also the ones I’ve found myself the least comfortable with on the first try. It takes around five minutes for the silicone to warm up and for my ears to adapt, but then it’s almost as if I wasn’t wearing them at all. Due to their shape they offer an almost perfect seal, so if the earphones you’re wearing provide any isolation at all you probably won’t hear a thing of what’s around you without needing active noise cancellation. The SpinFit CP100 works across a range of in-ear monitors including but not limited to: the 64 Audio Tia Fourte, 64 Audio Tia U18 as well as InEar’s ProMission X and Campfire Audio’s Andromeda 2020. In general, they offer improved levels of transparency and a linear neutrality compared to other silicone tips. However, their crisp nature does mean that they are a bit leaner when evaluating note size. Thus, they may not be the best choice for already thin and exacting IEMs. Foam tips such as True Fidelity & Campfire Audio’s Marshmallow provide a more fatigue-free listen in general but at the expense of utmost clarity and transparency. Conclusion 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.

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. 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. Here are the TWS earbuds I have in my collection and tried them with the CP360. Creative Outlier Air V2 with SpinFit CP360 use not following the ‘User Guide’ or any additional safety, use, or warnings included in the product materials. That preamble aside, the CP-500 has a soft flange along with a similarly soft bore. The flange also has a somewhat oily texture to it, resulting in a fit that’s not the most secure and requires a bit of a deeper insertion. It’s a very comfortable eartip but isolation is worse than the CP-100/145/360. This is an eartip I’d recommend if you’re someone who’s into “tip-rolling” (as in, experimenting with various eartips). The CP-500 provides interesting results with many IEMs.Eartips are a very personal thing. There is no good or bad in most cases, there is good fit and lesser fit, which depends on both the devices they are mounted on and the listeners’ ear canals. These variables create a large number of possibilities and uncertainties so that no eartip is fitting universally. These variables are: The midrange of the SpinFit tips does sway towards the leaner side of the spectrum with more defined transients. Compared to some of the better foam tips (True Fidelity & Campfire Audio’s Marshmallows), the SpinFit’s silicones are more neutral-orientated at the expense of the more rounded and softer impact that the former tips render. Treble As for sound, my impression is that they are quite neutral and I can’t hear significant differences compared to other tips like the CP100. This is actually desirable, so kudos to SpinFit! With the CP100, the Aurvana Trio’s mid-treble sounds a little harsher, while the midrange is slightly less articulated. I attribute it to a more filling bass and harmonics which somehow influenced the texture of the instruments, making them less clean.

Any item returned must be complete with all accessories, hardware, manuals, or instructions, and in the same "new" condition as when it was when shipped to you. Please send us photos or videos of it. 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 Spinfit have been making eartips for a while now, and their claim-to-fame is the name-sake “swivel” mechanism that rotates the top of the inner-stem. This in turn helps to achieve a deeper, more secure seal as the top of the tip (along with the sound-tube) literally bends to get closer to the inner-ear. Sound-wise, there is better bass performance than the Comply Foam while the upper treble remains clear. Sennheiser Momentum True Wireless 2 with SpinFit CP360The 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. Note that it is best to confer with SpinFit for specific recommendations for a particular model type as this list by no means encompasses all the brands out there. Model The CP145 is just a hair larger than the CP100 at 4.5mm, and is otherwise nearly identical. If you primarily use IEMs with larger eartips but want some flexibility to use them with smaller nozzles, the CP145 will still fit securely on most models while being more accommodating of the wider nozzled IEMs. While the CP100 fits on the Empire Ears line of IEMs, it generally is a little tough to get on, while the CP155 and CP500 don’t provide a snug fit. The CP145 came in just in between with a perfect fit. CP155 and CP500

Fits Jabra 75t, Google Pixel, and more without adapters. Has special adapters for AirPods Pro and Galaxy Buds. 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.The peculiarity of the CP100 is that they are tall (9.9 mm), but they are actually quite wider at 13.3 mm. This means that they won’t need to go very deep to seal off your ear canal and therefore will also be fine for earphones with short nozzles. Thanks to this good seal, bass is well extended and controlled, while the rest of the range comes out as well balanced and with no particular colouration and the same sensation of good control as in the lower area. As a whole, the sound is mostly unaltered and this also includes the “bad” side of this, as the tips won’t reduce peaks e.g. in the treble area. You must return an item in the same condition as it was received. You must also include, in the same condition as it was received: 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. While the SpinFit silicone tips do not provide the most bass impact or authority, they offer a higher level of refinement compared to the Symbio W, Shure Olive & Final Audio E-tips. The Symbio W hybrid tips offer the most contrast here with a more impactful bass and energetic treble. However, the SpinFit tips really master the treble with detail and control that the other silicone tips do not possess.
