CP145 has undergone various adjustments in shape and material. This model is a model that would never disappoint you. CP145 grabs the treble well and keeps the flexibility of the bass. Perfectly for audiophiles. Among all the SpinFit models, CP145 is the model that has been most often chosen to be the "IN-BOX" collaboration model. CP145 is rather longer than other models which makes it go deeper into the ear canals. Of course the patented design allows them to swirl and perfectly adapt to your ear canal structure. Plus I believe you'll find how the sound performance has been updated if you search SpinFit CP145 on the Internet. If you would like to enjoy the perfect fit and top sound performance with your IEMs, CP145 is the must-buy model! Which Size? The different size ear tips accommodate different ear canals. Choosing the proper size is critical for a secure, comfortable, and quality result. If you’re unsure, medium size fits most users comfortably. The Design SpinFit has an ergonomic concave design at the core to allow the ear tip to swivel, making it flexible to bend and twist to the contour of a person's ear canal. SpinFit ear tip is able to be inserted deeper into the ear canal, enabling less obstruction along the sound field dispersion path, which results in greater audio experience while providing maximum comfort. The Feature Enhanced Noise Isolation - Consistent optimal seal even for headphones with an awkward insertion angle, allowing increased noise isolation. Frequency Extension - Enhancement on treble and bass ensures a superior listening experience to the foam and the stock ear tips. Superior Comfort - Premium soft silicone material along with the ergonomic design provides outstanding and lasting comfort. Patented 3D Axis - Patented cushion makes them unique and perfect replacement for your stock ear tips. Warm Reminder from SpinFit Fitting and wearing experiences can VARY because we are all unique creatures! Please make sure you get the right model and the right size before placing your order! Review: Great upgrade eartips - These eartips are a great upgrade from the standard "hard" silicon stock eartips of my Moondrop Chu II. The silicon is very comfortable and soft, and has some extra grip that works great for sweaty ears. The price is a bit high, but pretty reasonable for 2 pairs. The passive noise cancellation is noticeably better in my experience, providing a sturdy and reliable seal that can handle jaw movement. Overall a recommended upgrade for anyone looking for a more comfortable, grippy eartip. Review: Supreme comfort, like they say. - I have pretty much the entire range of SpinFit tips, which I have bought to try and get good, comfortable, secure seals with my many Bluetooth earbuds and wired IEM's. I did not have the CP145 and saw that these were recommended for my Tin T2Plus and CCA C10 IEM's. I was using some CP100's and CP360's but these CP145's are almost the same as the CP100, but the port size is slightly larger on the CP145 compared with the CP100. Hence, they are easier to get onto the port, but still a secure fit to the IEM. The fitting onto the IEM's was indeed easier, but they are on there securely unless you want to remove them. I've found that even the smallest tip dimension change can make a big difference to the fit. I chose the M size, based on my other tips. Usually, I have to use a large silicone tip in my left ear and a smaller size in the right ear, where the tip rests in the outer part of my ear. However, with the "IEM" tips, which tend to fit more deeply into the ear canal, a common size works for both ears. Inserting the 'buds in my ears, the CP145's seemed to fit in my ear canals really nicely without too much, if any pressure. In fact, these tips make the IEM's even more comfortable than they were before. The tips are not holding the IEMs in my ear as such, just sealing the canal. The IEM body and pre-formed over-ear cable sleeve are what holds them in place. I test a secure fit by inserting the bud, then pulling lightly on the body. A good fit tends to resist the pull. These tips just slid out. I have tried the CP145's on my Sony WF-1000XM3 earbuds and they don't work for me. As mentioned, the tip doesn't hold tightly in my ear canal and so the XM3 falls out easily. It seals really well, but I get a more secure fit, though not much better, with the stock tips. The CP360's work well at locking in my concha, but they do push the earbud out further and the XM3 wobbles around on that knuckle. The ANC is worse also, as I cover below. I have yet to try them on my other BT buds, but I suspect the same result. Perhaps a larger tip would jam in my ear more securely, but then the fit and comfort won't be as good. Typically, SpinFits aren't so good when ANC is involved. The material is thin and tends to add length to the tip with that articulating knuckle. That means more noise can get through the tip into the ear. Typically, I don't use SpinFits on my BT ANC earbuds for that reason. They are always much more comfortable than other tips though. It depends on what is a priority for you. Since the IEM's are not noise canceling and actually don't have that good a passive noise cancelation, the SpinFits work fine in this application. The body of the IEM is not pushed out as the tip goes fully into my ear canal. So, the noise isolation is pretty much the same. Unlike with foam tips the sound profile doesn't seem to be affected much, though I do notice a slight emphasis on the treble. Overall, these have proven a worthy purchase for my IEM's. I can recommend them, with the proviso that everyone's ears are different and what works for me, might not for you. Fortunately, desertcart has your back with free returns. I went through 3 different sizes of AZLA Crystal tips until I found the size that worked for me on my Galaxy Buds Pro! Happily, I struck lucky with the CP145's on the first buy. ## Features - Eartip has a bore size of 4.5 mm which fits earphones that have sound port nozzle 5-6mm.

I use them on a pair of Planar IEMs I have, and they reduce some of the treble sharpness.
