SpinFit CP100 Plus for IEM - L - Medical Grade Silicone Patented Eartips, Secure Fit and Supreme Comfort, Reduce Allergic Reaction, One Set Fits Normal and Thin Nozzles(2 Pairs)(with Inserts)

SpinFit CP100 Plus for IEM FOR THE WIN! True wireless music lovers REJOICE! I bought the Sony WF-1000XM4's within the first week of their release earlier in June. The clarity, the bass response, the "OMG what is this!" reaction to the BEST active noise cancellation available today. Hate to admit it but the Sony WF-1000XM4's are worth every nickel of that staggering $279.00 price. I used the smallest set of eartips that came with the Sony's and they were great but lasted only a month and a half of service with relatively "light" daily use. The Sony eartips eventually tore and, being a fellow who LOVES music and can anticipate disaster, I had ordered the Comply eartips. I purchased 2 sets of the small size. Later, in a Sony product related online forum, someone mentioned using the SpinFit CP100 Plus for IEM and absolutely RAVING about these eartips. Intrigued, I found them and although somewhat questioning the relatively high price for eartips, I hit the purchase button. Now, 2 months have passed and the replacement pair of Comply eartips gave up the ghost and I installed the SpinFit CP100 Plus for IEM. I almost instantly I KNEW! These eartips make an already great experience with the Sony WF-1000 XM4's into something approaching sublime Perfection. The smooth silicone slips easily into the ear canal and I don't experience the weird "binding" sensation even on a humid mid-September day in Washington DC. No sweaty, or sticky feeling inside my ears. 100% GONE. The Sony's feel more stable and secure in my ears! ALL of what I mentioned earlier in my review of the Sony's: Clarity, Bass Response, Snap, Articulation and separation of vocals and instruments, and YES, that magical Sony active noise cancellation - it's ALL THERE but even MORE! Adding the SpinFit CP100 Plus have transformed what was already a great true wireless experience into something Magical. It's a shame because Spin Fit barely advertise that their eartips fit Sony's flagship earbuds but THEY DO! I am now also keenly aware that the "Achilles heel" of true noise cancelling earbuds (or at least the Sony's) must be the eartips. Sony don't even offer an "extra small" size, and even the "medium" Sony eartips were way too large for my ears. The SpinFit CP100 Plus for IEM "extra small" size have made me even happier with my purchase of the Sony WF-1000XM4's. Buy these without hesitation, and if you happen to own the best noise cancelling earbuds available today (SONY XM4's!), these eartips are the BEST upgrade you could make to perfect your user experience. The extra small size is the icing on the cake. Do NOT hesitate to buy these fantastic eartips. I have just installed them so I cannot comment on their longevity, but that is AOK with me. I will be ordering several more sets of these incredible eartips.

They come in pairs, theyre so soft you forget about them, and they improve the fit so so so incredibly. Iem's and buds rely on fitment quality to ensure sound quality, and truth is these guys are the only guys to do the RnD to ensure that fit. I bought the Kz-ZS10 pro off of stellar recommendations and reviews from youtube and reddit, but noticed a small subset of disappointed folks saying they slide out, or have poor bass, or that their highs are uneven and shrill; i figured "theres always weirdos, right?" Turns out im a weirdo lol The bass would cut out depending on if one of em would slide out, ruining the seal, and i just kindof settled with it as it was, they were cheap and that was fine. Now that Ive lost a tip and I was looking around for upgrades or replacements Ive found these guys and OHMYGOD the bass is there, just like the reviews. Not overkill in quantity, but it goes lowwwwww (for 50 bucks) the sound stage is pretty massive now too, and the highs are more sizzly than sparkly, but at least theyre even (again 50 bucks+13 dollar tips, not bad) Sometimes they still slide around and I lose bass in the left but whatayagonnado. Its a massive upgrade as it stands and I didnt even have to buy new buds. I even have a spare in case these ware out or I buy my gf a set of iem's.

I bought them to improve the sound quality of headphones that already sounded good. The result was that it didn't make much difference, but the earplugs still felt very good and comfortable and sealed as well as possible given their size and length.

After reading many of the reviews on these ear tips, the issue of proper sealing within the ear cavity has run the gamut from terrible, to no change, to awesome sound change. Sound perception is totally an individual preference and is greatly impacted by the ear tip to ear seal produced within the ear canal/cavity. I just purchased the Spinfit CP100+ for my Sennheiser MTW 4’s to replace the OEM silicone tips. The OEM tips sounded OK, however became very uncomfortable after using for just 20 minutes. So I wanted to give these a try after reading many reviews mentioning increased comfort levels. I can honestly say the comfort of these tips (different silicone material used) makes these tips wearable for long/extended time periods. Back to the sound issue. My MTW 4’s have a feature within the app called “Fit Test” results ranging from Poor, to Fair, to Good fit. I believe they run algorithms using low and high frequency sine waves with a tone played separately and combined to measure the seal produced within the ear cavity. When comparing the OEM and Spinfit tips both registering a “Good Fit Test” reading, clarity, crispness, detail, mids and treble, spatial effect, and separation were basically similar, however the bass was noticeably improved, deeper, richer, and a bit more thump. I will certainly use these as my go to ear tips.

I've been trying out different tips for my Sony WF-1000XM5 In Ear Headset. Until I tried the SpinFit CP100 Plus (Large) Silicone tips, I found I was not getting a good seal with other brands & types vs the stock Sony supplied tips. The Large size of Sony tips seemed to seal OK but was marginal on security of fit during activity while also giving me a little discomfort in my right ear which apparently is a little tighter than the left. Despite this, I gave the Sony tips some more time before deciding they could be better and then trying a couple of brands of 3rd party tips that were all outperformed in my case by the Sony tips. Then I bought a set of the SpinFit CP100+ tips. The large size of SpinFit CP100+ is a bit larger than the Sony Large, but despite this, they are more more comfortable than the Sony's, for me at least; YMMV. The Medium SpinFit is the same diameter as the Sony Large and I may give the CP145 model a try just to make sure I have the right size and performance. The real and very pleasing surprise with the CP100+ was the immediate improvement in sealing with a resulting very substantial improvement in sound quality. These will never compete with my home system speakers, but the jump in audio performance was quite literally astounding. Your results might well be different, but I was almost shocked at the magnitude of improvement I got. For travel and office use which is my use case for the In Ear Monitors, I am very pleased and recommend you give these a try as they are quite reasonably priced for a two pair pack. Just keep in mind that the size is a little different than Sony as is the shape. With respect to security of the fit, I could not shake these free no matter how violently I tried to shake my head, so workout use appears to be just fine too. I haven't checked out the full suite of Sony features in detail with these yet, but so far, the headset appears to have no issues responding to voice or movement based control and transparent mode is still usable, if maybe degraded a bit. The packaging is also very good, opens quite easily to display the instructions, and leaves you with a small two piece blister pack you can keep your spare set in. Even with the slight discomfort (easily bearable) in my right ear, I am much happier. As I said, I may give the CP145 model a try just to see if there is a little more to be gained with their slightly larger aperture and longer shape. Either way, I am sold on the SpinFit brand that in my case at least has really brought out a lot more of the XM5s performance and utility compared to the stock Sony tips. 5 stars.

These work well with my soundcore liberty buds. The stock eartips were not small enough for my ears. These are slightly smaller than I'd like but that's a learning curve error as I wasn't too familiar with spinfit sizing so I know now that a S or M may be better. The SS are still a better fit than the stock eartips though. It is really hard to find alternate eartips for the soundcore liberty earbuds as they are the eartips fit over is an odd shape but as long as these work

Good product easy to put on too. Fit is hit or miss it did not work for my left ear though. Great price. Comfortable for a few hours is okay.

Like every Sony WF-1000XM4 owner, I quickly found that the OEM foam eartips literally crumble and fall apart with daily use. I tried a replacement memory foam set from Amazon which didn't degrade but instead easily became detached from the plastic ring which holds them to the earbuds. Super glue worked but would eventually fail while also making the foam "crunchy". I also tried silicone eartips I had leftover from a few Anker Soundcore earbud sets but those could never pass the Sony eartip seal test in the configuration app. I can report that the SpinFit CP100 tips do pass this this test. A couple of notes, you don't need the sleeves for the CP100s to fit the WF-1000XM4s. I can't speak to sizing as my OEM tips turned to dust a long time ago but I used the medium OEM tips, the large replacement tips, and am using the L SpinFits. As to comfort, I find SpinFits extremely comfortable with a tight, confident fit. In the past other silicone tips were very much the opposite, feeling loose and precarious unless the earbuds themselves had wings to force them to stay put but not these. I have to admit they don't look or feel to the touch any different or better than those loose-feeling tips but the performance seems to indicate that they are. I'll update this review should I encounter problems with reliability but in my past experience silicone eartips have easily outlasted the earbuds' batteries with daily use over two years. I generally use earbuds thirty or so hours a week every week and have never had a set of tips fail before I had to replace the earbuds themselves. Lastly I think someone in the reviews mentioned the packaging on these being difficult to open. While there isn't instructions on the packaging, it's actually easy to do without tools unlike most packaging. The back peels off, for me it was easiest above the hanger cutout, revealing more instructions and allowing the plastic to pop out which then separates at the edge, not at the pod where the product is. Easy-peasy.

Reçu aujourd’hui pour mes écouteurs Sony wf-1000xm4. J’ai l’impression d’avoir un nouveau modèle tellement la qualité musicale et la réduction de bruit s’est envolé vers les sommets que j’attendais plus. J’étais déçu par l’absence de basse et la mauvaise réduction de bruit. Un super choix. J’ai aussi un casque Bose Ultra dernière version car passionné de musique pour info. Par contre je ne peux plus me servir des écouteurs Sony qui fonctionnent plus CAR CHARGE RESTE 5' et le service clientèle est plus que décevant. Cadeau de Noël recu il y a 2 ans commandé sur Amazon (facture en possession)

Llevo varios días probando las nuevas almohadillas y puedo opinar lo siguiente: -Me ha sorprendido, honestamente creí que no alcanzarían la calidad de sonido que con las originales incluídas con Sony, per incluso siento se escucha mejor. -Son más cómodas y siento que los audifónos se mueven menos con las almohadillas Spin Fit que con las originales, las originales ejercían presión sobre el canal auditivo lo cual al paso de un rato provoca molestía, con estas no es así, sin embargo, se quedan fijas por más tiempo, el material con el que están hechas no se resbala. -Yo escogí la talla S de Spin Fit, en las originales usaba la talla incluída de fábrica o la chica, para que lo tomen en cuenta. Vi muchas opciones, y sin duda me siento feliz porque los WF-100XM4 son un gran gasto, uno quiere que se escuchen como deben de, y con estas almohadillas siento se le saca un excelente provecho. Lllegaron en 5 días desde TX a Edo. Mex.

Product works well and fits well. I'm very pleased with these.

Buenas puntas que parecen duraderas y muy comodas depende como todo del oido que tengas.Parece que mejora levemente la claridad del sonido y aislan bastante bien.En contra el precio muy elevado pero teniendo en cuenta que vienen 2 pares y parecen duraderas y comodas creo que el precio se ajusta a la calidad que ofrecen.

I have tried purchasing many tips for my Shure 415s and these are the best I have found and at a great price. Good fit and they stay in my ear. I originally ordered the large, they were ok but did not sit well so I went with a medium. If you are an average adult alpha male, I’d recommend the mediums. Good purchase, but with confidence.
