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)

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.

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.

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.

着け心地最高。 音は好みの問題なので、これで良くなる悪くなるは人それぞれだと思いますが、私は完全に良くなる方向に振れました。 もっと他界商品もたくさんありますが、当面これをリピート予定です。

En remplacement des embouts de KZ PR3: plus de basse, meilleur isolation au bruit extérieur, confortable.

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.

After trying different brands of ear buds, this model (Spinfit CP100 plus) is the best value for money. Received 2 days after ordering on free delivery is so amazing and much better than other online websites. Definitely and highly recommended.

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