SpinFit CP155 for Wide and Long IEM Nozzle - M - Patented Silicone Eartips for Replacement (2 Pairs) (for Nozzle Diameter from 6-7mm)

The **SpinFit CP155** is a great pick if you’ve got IEMs with wider or longer nozzles. The fit is secure without feeling too tight, and the added length helps get a deeper, more stable seal. Comfort is excellent for longer listening sessions, and the flexible design lets them sit naturally in your ears. They also do a nice job enhancing bass response while keeping the overall sound clean. If you’ve struggled finding tips that fit properly, these are an easy win.

I have two different sized ear canals, and because of that I very rarely am able to get a good seal with silicone eartips. I am typically relegated to using foam tips, especially on my IEMs with large nozzles. These are the only silicone eartips I was able to get to work for me in conjunction with my IEMs, and they are amazing. Super comfortable, and extremely soft. I highly recommend.

I use these with my IEMs, and the comfort is great. I do notice it will slip out if earwax slightly builds up, compared to stock eartips. However, these are worth it if they fit your ear.

This ones are really comfortable, can keep em on my ear the whole day if i want without feeling any discomfort, the rubber is soft but sturdy enough to stay on your ear without falling out. If i have to describe the difference in sound i can perceive from the ones i had, i would say this ones has less bass but a clearer sound. Keep in mind the red portion of the rubber is really soft and it expands so it till NOT hold by itself, it HAS to go deeper on your earphones tips to keep a grip of it, so it might or might not hold well on your earphone depending on it's design.

Using with Truthear RED and I found that these tips did not improve comfort of the IEMs very large diameter nozzle. The CP155 tips are too pointy at the proximal end and I need to shove them deep into my ears to get a good seal. This created pressure and soreness very quickly. Also, the mounting cylinder of the cp155 is too thin and flexible. The tips push back and ride up over the nozzle lip when inserted into my ears. The flexible "spin" feature of the tips then bottoms out on the nozzle opening and becomes rigid, just like the stock tips. I had to reposition the tips on the nozzle after every wearing. For me, Truthear Red needs a wide, "shallow fit" style tip to not cause discomfort. I'm using Hifigo x ZReviews render tips currently and they work much better with this particular IEM. 3 stars across the board because they are great quality and design, just not a match with Truthear RED.

Perfect if you have deeper ear canals. These are great for cleaning up harsh upper mids and lower treble. Say goodbye to shouty sibilance

Before I got these, I had to very slowly put in my IEMs and wait for a few minutes for a burning sensation to subside, and if I adjusted the fit after I had gotten used to the feeling, it would start to hurt again. These go in incredibly easy but still make a good seal with my ear canal. I can't tell any difference in noise isolation or frequency response personally, but my hearing is not outstanding so if you're sensitive to that sort of thing you may notice something that I'm not picking up on. For my money this is a slam dunk purchase, cost a fraction of the IEMs and makes them wayyyy nicer to use. My compliments to the creators!

Unfortunate. Very comfortable and provides above average seal. But, despite a seemingly tight fit to the Jaybird earphone, each continually come off (in my ear) when removing. I’ve been using in ear since the first Etymotics and current go-to are the Klipsch X20. I inherited new Jaybirds for my daughter (didn’t like the in ear) and will use what came with them.

Las compré específicamente para unos audífonos Soundpeats Opera 05. Las almohadillas de fábrica no se ajustaban bien a mis canales auditivos, por lo que se filtraba mucho ruido exterior y por tanto la calidad del sonido era muy pobre. Además el cuerpo de los audífonos me producía molestias en el pabellón de mis orejas. Dejé de usar los audífonos por esas razones. Gemini, la IA de Google, me recomendó este producto y le quedaron perfecto a los audífonos. Los graves ahora se escuchan profundos y limpios. Los medios y agudos muy definidos. Dado que las almohadillas son más largas que las originales, los audífonos ajustan mejor en el canal auditivo, sellan perfectamente y ya no me molesta el cuerpo de los audífonos en las orejas. No son almohadillas baratas, pero en mi caso valió la pena porque los audífonos prácticamente revivieron y ahora sí se puede apreciar la calidad del sonido que producen. Un producto totalmente recomendable.

Let me preface this by saying that the Truthear X Crinacle Blue (v1) have CHONKY nozzles coming in at 6.8mm, To elaborate, after 1 hour of gaming and music listening and removing them....I could literally fit my thumb tip into the entrance of my ear canal...absolute insanity (and pain). -Pros I was close to returning those IEM's until I saw a reddit post recommending these tips, I was skeptical, how can a similar material possibly make those chonkers any more comfortable? Well I stand corrected (for the S/Pink)! These have been amazing and have allowed me to sit these IEM's in my ears for well over an hour and it feels the same as the first second of insertion, no discomfort or friction issues. This makes long stints of using them enjoyable. -Cons If you are a bass or sub-bass head these are not the tips for you, feels like a 1-2dB reduction in bass and sub-bass and no boost in treble but that bass being subdued definitely brings out the upper mids and treble. Not enough to be sibilant but if you rely on that audio "muscle memory" then you will find it jarring. All in all when gaming or listening to EDM I still use the small stock tips, for travel or long movie watching I definitely will be using these from now on. Sorry I could not test sound stage or imaging because my mates I play games with have taken a break atm.

Perfect fit for various IEMS.

These silicon Spinfit eartips (for me the size L) are the ideal choice for my Audeze iSine 20 earphone. Neither of the Audeze factory made tips could give so nice bass sounds, as their blunt form is not good to go enogh deep into the ears. Now my iSine20 is like a brand new, perfect earphone! I highly suggest it!

Son bastante buenas para auriculares con la boquilla gruesa. Son las únicas tips que han conseguido que mis Blessing 2 no fueran insoportablemente incómodos. Intensifican un poco los bajos ,sellan bien.
