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 had heard a lot of good things about these ear tips in the past from reviewers on youtube.Finally took the time to order up a set. Coming in a set of two pairs, these should last a long time. The fit is good on numerous wider bore IEMs in the 4.5mm to 5.3mm outer diameter nozzle.Once inserted the tips conform well to the ear canal and feel far less intrusive than other tips. They also don’t cause any ear canal fatigue if used for an hour or more. They seal well. I do recommend these for band players who use IEMs for on stage monitors. Also good for travel listening on airplanes or trains.

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.

I don't mean to over hype but these ear buds are hands down the best ones I've ever tried for my IEM'S. THE SOUND, really is amazing and it's worth every penny. My only WISH is that there was a box that had multiple sizes. Sometimes it feels like a waste to get two of a size and you have no idea if it even fits properly. I suffer from tinnitus and some hearing loss so it's been hard finding the right ones but I really feel like I've found em.

Oddly enough, one of them was a tad smaller than the others and wouldn't seal. Luckily I only needed one pair and changing it out solved the problem. Very comfortable tips and they help my IEMs sound great!

I had to purchase all three sizes; the small is perfect for me; my earbuds fits snugly in my ear; comfort is fantastic!! TJ

These tips are great but you do have a tendency to come off the post and Stay Lodge in your ear. Which is unfortunate. Sizing is very important with all tips for iems and I wish that the company had more comprehensive listing of compatible iems. That being said I did order a different pair from the same company paying particular attention to how they would sit in my ear and I've had no problems

I bought the Belkin SF Freedom earbuds on sale at Christmas and they sounded fantastic, but they wouldn't stay in my ears when I was outside in the cold Canadian winters. I didn't want to return them because they sounded so good and the price was right, but I was disappointed. I found the Spin Fit CP145 on Amazon and read the reviews and the CP100's, but the reviews said the CP145's were a bit longer and would fit in the ears better. They sure did. I have worn them all morning and they fit perfect. They haven't fallen out, they are very comfortable and the sound is a lot better. No outside noise. Very happy with these, even at this cost. Medium size has been perfect, no need to get small, medium and large to try them all.

No he probado muchas puntas, pero a diferencia de las de silicon estándar, sí son más cómodas. El truco que tienen es la bisagra que les permite acoplarse mejor, y de hecho quedan más adentro del canal auditivo.No aísla completamente el sonido, pero a mi parecer está bien.Los uso con mis FiiO FH3, quedando muy bien a la boquilla, pero SI CAMBIAN EL SONIDO disminuyendo los bajos (y el punch) y favoreciendo un poco las frecuencias medias, que a mi parecer van muy bien con esos audífonos y vuelven más disfrutable la música instrumental (recordar que los IEM de FiiO tienden a favorecer las frecuencias bajas). Finalmente, son como agregar un "sabor" más, con mucha comodidad. Para mí, sí valen el dinero.

Son cómodas y funcionan a la perfección. Las compré para unos auriculares Moondrop Blessing 2 que tienen las puntas muy gruesas y encajan bien. También se sujetan bastante bien a pesar de la superficie de resina pulida. Creo que son mejores que los originales de Moondrop. Los recomiendo.

NOT much to say, it is what it is.

Utilisés sur un casque IEM Audio Technica Pro, ils remplacent avantageusement les embouts d'origine.L'écoute et vraiment améliorée, notamment dans le registre grave, sans doute à cause d'un meilleur contact dans le conduit auditif et d'une isolation plus performante.Bien construits pour durer.Seul reproche leur prix élevé.
