SpinFit CP145 for IEM - L - Patented Silicone Eartips for Replacement, Secure Fit and Supreme Comfort (2 Pairs) (for Nozzle Diameter from 5-6mm)

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.

I was kind of tired of those damn hurting earpices in my IEMS. I had no hope but tried them anyway. And they really surprised me. They do not seal completely as foam does, but are super soft and comfy, and honestly, had great sound quality anyway. These are kind of expensive, especially for a set of 2 pairs, but completely worth it. So far after several months of use, they are still new and functional.

Upon opening I noticed they were very soft and pliable. Immediately thinking they'll hopefully be so much softer in my ear canal and can be more comfortable for longer periods at a time compared to the stock tips of the ie40's. These aren't as tight as the ie40's so you won't get that little satisfying double click putting them on the nozzle like the ie40's. They stay on the nozzle without coming off so don't worry.The only downside is that they are wider than the stock IE40 Medium silicone tips. They're around the Large size or in the middle. Definitely not IE40 Medium. So if you're getting these to replace the ie40's and small is too small and medium is too big I'd recommend getting CP145 in a Small as it would fall directly in between those two sizes I assume. I wish Spinfit had a variety pack of a pair of small and a pair of medium or another one with medium and large. That way we can get the best fit without having to hope for it to be a perfect fit if it's your first time getting an iem tip as I think spinfit falls under with it's pricing being relatively affordable and will be most peoples first tip purchase. Keep the two pack just like these but hopefully they can add the different sizes in the future in one package.Now for sound quality. MUCH smoother than the silicone IE40 medium tips. No more slightly hot s sounds. Not that the IE40 is treble piercing but it's just slightly on edge at times if listening loud or gaming with gunshots going on all the time in video games. Bass is just the same but vocals seems to be smoother and slightly more deep. Just a tad bit though. Subbass is pretty exactly the same. Just that region for male vocals seem to be SLIGHTLY fuller. Soundstage decreases with these tips a bit. The airiness of the stock ie40 tips is no longer there.These are great for podcast listening and vocal's really. For gaming, or jazz, acoustic, and anything else instrument related I'd opt for the stock tips. String instruments sound wider and a bit more clear. For all day comfort and house music and electronic music and such I'd opt for these. Just keep both tips nearby so you can switch depending on what you'll be doing. Walking around in public? THESE. They don't block out as much noise so you'll be able to hear your surroundings. Though with the increase of ambient outside noise it doesn't effect the sound too much. Bass stays the same as noted.If you're on a train or around loud things I'd probably not wear these for that. The stock foam tips may be better. These aren't as noise isolating as the stock ie40 tips so keep that in mind. Which I much prefer because I'll be using these iem's in public too or under a motorcycle helmet for navigation. I'd say it's about 2db less or so attenuating than the stock medium tip. Not much of a difference. Just slightly.

This did give a little better sound and bass in my possibly fake Sennheiser 500 Pro IEM that I got on ebay. Even if they are real or fake they sound pretty good, but the small Spin Fit did improve the audio quality. I found that what ever ear tip I do use, Spin Fit or otherwise that if I put a pair of over the ear headphones on as well (not plugged in), along with the IEM that the bass response improves. The one problem I had with the Spin Fit is that the left ear tip would come off in my ear when I take them off, so I put a very minuscule amount of Elmer`s white glue and put it on the IEM nozzle and then put the spin fit on and spun it a bit and then let it dry. No more ear tip falling off in the ear. Overall I am happy, but not knowing the size I needed I bought all three., large, medium and small. I tried the medium but it seemed to big and the sound was not right, than I tried the small and the sound improved and it fit better in my ear.

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.

Here's the proofread version of the product review:Pros:* These earbud tips look and feel amazing.* Even in the ear where I usually struggle to get a good seal, these seated and sealed better than anything I've used before.* Sound quality was noticeably improved thanks to the excellent seal, which they achieve without the uncomfortable pressure of other tip types.* They felt very light and comfortable in my ears.Cons:* Unfortunately, either the seal is too good, or the connection between the top part and the earbuds is not strong enough. (I used them on my Sony LinkBuds S.)* After my first use at a store, I tried to remove the earbuds before checking out. As I pulled out one earbud, the bud itself came out, but the tip remained firmly stuck in my ear canal.* It was impossible to remove the tip with my fingers, as it would only push it further in.* While I know it wasn't a true emergency, the sensation of having something stuck deep in my ear canal was incredibly unsettling and caused a significant amount of panic.* I then tried to remove the second earbud slowly, but the tip also popped off as I pulled it out.* I ultimately had to use tweezers to grip the center connecting tube of the tip to finally remove it.Conclusion:* I suspect this issue was a combination of an exceptionally good seal and a less-than-ideal connection between the bud and the tip in my ears.* After this experience, I was too anxious to try them again.* If this issue hadn't occurred, these tips would have received 5 stars.* I strongly recommend that anyone who tries these tips ensure a secure and firm connection between the tips and the earbuds before use and test to see if they can be easily separated.

Pair these with the Linsoul KZ ZS10 Pro in ears. Way more comfortable fit then factory tips. I almost felt a burning sensation when I used them. I tried foam and didn't like fit. I am a Production Sound Mixer and have these on for long periods while we shoot. Nice upgrade. I'm trying the medium first..

SUPER comfy, and GREAT for making wide nozzle IEMs fir your ears. HIGHER recommend.

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.

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 fromFIIO. 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.

Met betrekking tot de klank heeft Fiio net zo perfecte oordopjes, maar voor mij passen de Spinfits het beste.

Ich verwende die Größe M anstatt der Stock-Eartips M, welche in der Verpackung des Moondrop Kato beigelegt waren. Das Silikon ist sehr weich und der Höhrer passt nun wie angegossen. Das Geld ist ausgezeichnet angelegt, da die vorherigen Eartips extrem unangenehm saßen.

NOT much to say, it is what it is.
