## Description

missing info

Review: Best fit for Sennheiser ie600 - Better seal, look, comfort, better sound isolation, better lows highs due to better seal. It goes slightly bit deeper into ear, but doesn’t get uncomfortable at all. It does reduce frequency of itches as advertised. Definitely recommend. Don’t bother with cp100 for ie600. Not a good one compare to these.
Review: Perfect for FIIO FH5 - Been looking for suitable tips for my FIIO FH5’s. Using Inairs on my Shure SE215 which are perfect for those. Didn’t work at all for me on the Fiio’s. Felt like they were jammed in my ear and effected the sound, lots of low end but dulled the mids / highs. Similar experience with Comply tips on the Fiio’s too. Tried the Spinfit 155 (medium) which gave a lovely balanced sound, to my ear anyway. They were just a little loose on the nozzle and a tad too long which irritated my ear canals after a while. The Spinfit 145 (medium) are perfect. Snug fit on the nozzle, good seal in the ear canal and used for hours with total comfort. They give the earpieces a better, secure fit than the supplied tips from FIIO. Lovely low end thump but with all the clarity the FH5’s possess. For me the 145’s are a perfect match with the FH5’s. Very subjective I know, but hopefully helpful for anyone looking for suitable tips.

### ⭐⭐⭐⭐⭐ Supreme comfort, like they say.
*by A***E on 26 January 2022*

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, Amazon 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.
