The CP100 has a 4mm opening and is the all-around, works with just about anything tip. It’s small enough to work with IEMs with smaller nozzles, like those on 64 Audio’s line of IEMs, but still big enough to stretch onto Noble or Empire Ears wider nozzles. The challenge is that with bigger models, you’ll generally want a little more room to work with, rather than having to fight to get the tips on and off, and potentially damage them. The CP145 seem to tame bass a tiny bit to give a small boost to the upper midrange and to treble; mind you, we’re talking about a difference that’s not major and is in fact relatively minute. In other words, you won’t be able to make a warm IEM a neutral one, but you will notice a smaller difference compared to other tips. Overall my sensation is that the CP145 deliver a wider soundstage, probably thanks to the larger presence in the upper area, and more accurate imaging compared to the CP100. They still deliver a generally neutral signature. 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. 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 If it is plastic sealed when you get it, it should remain plastic sealed. Some types of goods such as CIEMs and custom cables cannot be returned.

Got into head-fi in mid-2019 under the username kmmbd, and has been reviewing audio gears sporadically on his personal Medium blog since 2018. His introduction to portable audio was through a Walkman cassette-player in his pre-teens, and music has been his getaway ever since.He harbors a minor OCD regarding the tagging and organization of his music library (which is all digital on a local NAS). Also, spends too much time custom-theming his desktop Music Player for no apparent reason.In real life, he’s a Bangladeshi living in Munich and currently doing his MS in Computer Science, majoring in Computational Biology. He’s a penchant for the academia and research, though life is strange so he’s still unsure how things will turn out in the long run. The SpinFit CP360 provides a comfortable fit with its high-quality silicone ear tips and perfect seal. The optimal seal brings better bass performance and smooth treble frequencies. The soft and flexible silicone material provides a high level of hygiene and long-lasting comfort. They are made up of medical-grade silicone material. Wide Compatibility:-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. 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:
mm 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. It is impressive the quality of refinement the SpinFit tips are able to extract from the top-end. This is likely owing to its ability to create an effective seal and direct frequencies straight towards the eardrum. Synergy & Pairing 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.
How and why SpinFit eartips work
I don’t hear significant difference when I fit the Sennheiser MTW2 with the CP360. Perhaps it’s because the MTW2 is already quite bass-heavy. The earbuds could not stay flushed on the ears due to the longer ear tips. SpinFit CP360 ear tips with Sennheiser MTW2 Technics AZ70 with SpinFit CP360 SpinFit is one of a small group of people making silicon ear tips. I think silicon works best as it allows for a more durable tip. They still fit in securely and create a good seal. While Comply Tips will wear down over time, SpinFit tips just keep going. 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 Accidents, abuse, misuse, improper installation, problems with electrical power, acts of third parties. The CP100 provides an easy fit on an IEM with smaller to medium sized nozzle like 64 Audio’s Universal fit offerings. CP145
