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. 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. SpinFit have adopted a simple yet elegant underpinning their ear tip design. There is an ergonomic concave design at the core which allows the ear tip to swivel. While conventional ear tips do not always direct the sound to the eardrum, SpinFit aim to maximize this with their patented 3D axis. 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 CP100+ ear tips are a recent release of SpinFit’s and an update to the current CP100 model. The CP100+ tips incorporate medical-grade silicone material to promote a more durable and comforting fit as well as a stiffer inner core. In terms of sonic impressions, there are subtle differences compared to the original CP100 model. For example the CP100+ has a slight bass elevation and more control over the higher frequencies than its original counterpart.
Some earphones come with a generous selection of eartips, others don’t. And in some cases, none of the eartips fit or provide an effective seal for the listener, so that the sound quality is compromised. In such situations, third-party eartips come to the rescue. I did a comparison on the Sennheiser IE300 with the CP100+ and CP360. My ears detected the following characteristics: Some may find that tips are a shade crisp for their tastes and hence foam tips may be more their flavor. However, trialling and experimenting with different combinations will aid the quest to find the perfect sound.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: SpinFit claim their double-flange tip to offer ‘triple-flange’ isolation. However, Etymotic’s triple-flange eartips generally offered superior levels of noise isolation when compared to SpinFit’s model. With that said, the SpinFit double flange tip was far superior in comfort and it was surprisingly unobtrusive in prolonged listening sessions. With the easy 360 o rotation, the SpinFit ear tips were perhaps the easiest silicone eartips to install and remove from any in-ear monitor nozzle. This applies for most countries. However, large items such as headphones and desktop DAC/AMPs (e.g. HarmonicDyne G200, MUSICIAN MDP-2, and etc.) are excluded.
On the whole, the SpinFit CP100 does improve the bass presentation slightly, so it’s something you should consider if you needed that little more bass extension. SpinFit CP100+ (Preview) Quality of the bass from SpinFit tips is quite impressive with well-defined notes and good texturing across the upper bass and lower mid transition. Granted, it does not have as much weight behind it as True Fidelity foam tips or Symbio W hybrid tips. However, it pairs well with already capable in-ear monitors with bass which is tauter and more disciplined. MidrangePassive 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 Eartips do make a difference in our listening experience. They may not always have an influence on sound, but they do change the way you wear your earphones and this makes all the difference between listening to music while being comfortable and doing so while swearing against the pain in your ears. The SpinFit line-up is quite complete and gives you a lot of choice to get the eartips that better suit your needs, from very deep insertion to a very shallow one. All of them offer a great level of comfort, thanks to the soft silicone and to the incredibly clever design SpinFit came up with. SpinFit eartips are a game changer and can completely change (in a very positive way) the way you experience your favourite earphones.
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. SpinFit has a unique ergonomic cushion design at the core of the ear tip, which allows the ear tip to: 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. The AZ70 has a neutral sound with the original ear tips. With CP360 ear tips, the bass improves in the meat which makes the AZ70 a little more enjoyable. SpinFit CP360 ear tips with Technics AZ70 Audio-Technica ANC300TW with SpinFit CP360

Another effect on the sound I find that SpinFits can have is a slight boost and opening up of the upper mids region. Instruments like trumpets, clarinets and flutes can become more prominent and forward. Depending on the tips you are coming from, it can have a slight increase in the perceived soundstage as well. On top of that, you can tell from the graph below that the CP100/CP100+ have slightly higher peaks in the lower treble as compared to regular foam tips as well. Eartips manufacturers can frolic as there is no real competition between them: all their products are different and there is no universal fit for any earphone/ear canal combination. Cons: Not really a con but it does tweak sound a little, might even be a Pro depending on preference The CP100 provides an easy fit on an IEM with smaller to medium sized nozzle like 64 Audio’s Universal fit offerings. CP145 Spinfit ได้ไหม ตารางนี้อาจจะพอช่วยได้บ้างครับผม แต่จะมีตารางแยกของแต่ละรุ่น แต่ละไซส์ให้อีกทีในบทความนี้ด้วยครับ โดยวันนี้แอดมินได้นำเอามาแนะนำ 5 รุ่นจะเป็นยังไงเราไปดูกันครับ
The CP100 and CP100+ tips dry up the sound a little. Hence, I find them perfect for IEMs that I find are a little too warm for my liking, or too mushy/too much decay in the bass. In terms of bass quantity, it is a little subjective to the previous tips you were using. On the very plausible assumption that the SpinFits improve the seal you’re getting, the bass quantity and extension will definitely improve. Munich, Germany. Head-Fier since 2019.

SpinFit’s double-flange tips offer further levels of sound isolation with an even superior seal compared to the flange tips. Again, they are a good fit for poorly isolating in-ear monitors without compromising on comfort during prolonged listening sessions. CP100+ Ear TipsThe 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. By their inherent design, silicone models are generally inferior to foam when it comes to prolonged listening sessions. However, unlike some other silicone models, the SpinFit single-flange tips do not irritate or feel particularly obstructive. The use of premium-grade silicone here has definitely aided a more ergonomic listening experience and other companies should follow suit. 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 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
Great Deal
