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.
Review: Definite IEM tip Upgrade - I have heard a lot about these tips IEMs and figured that it was time to try them out. I have struggled with IEMs that have a larger funnel (Truthear Crinacle Zero Red) and decided to try these tips on some KZ Zax that seemed to cause me some fatigue. These tips are definitley an upgrade and support good comfort over time. I mainly use my IEMs for gaming so I have these in use for about 2 hours on average. There is no fatigue and provide good acoustics and sound isolation. The end of the tips can compress and also pivot to really align with the ear canal passage. If you struggle with comfort then I would suggest these. Please take note that these will not make larger funnel IEMs feel much better if you are already dealing with discomfort due to the larger size.

### ⭐⭐⭐⭐ Fits BASN BMaster
*by B***D on December 4, 2023*

These fit BASN Bmaster stems. The small fits my ears well, as hoped, and seem to make a good seal. However, they did not solve a problem I seem to have with BASN IEMs: they push out. They're comfortable for long wear if I can get them to stay. I can't really fault them too much for something that's more of an issue with my physiology, and possibly the IEMs themself.
