Review on 🎧 SpinFit CP360 Silicone Eartips (L/M) - Replacement for True Wireless Earbuds, Compatible with WF-1000 XM4, Beats Studio Buds, OnePlus Buds Pro, and More (2 Pairs) - Nozzle Diameter: 4-5.5mm by Tom Beland

Bought a Jabra Elite Active 75t a few weeks ago and couldn't find a good seal. If I moved my head or my jaw (to speak), something would shift them and make the sound "tinny". I found I stuck the 75t as deep as possible in my ear canal just to get a decent seal, but it was causing me a ton of pain in my ears, not to mention I still have to adjust them every few minutes had to. The problem was that the included Jabra ear tips didn't flex enough to ensure a proper seal. This is the first time I've encountered an issue with one of the hundreds of IEMs I've owned over the years and I was close to returning the headphones. After researching the internet, I found that several people were using the SpinFit CP360 tips with the same problem. Thought it might be worth a try for $12. The earbuds arrived this afternoon and I'm already checking them! So here are the pros and cons - Pros - They fit the Jabra 75t earbuds perfectly - you can feel them snap into place. - They fit easily in the charging case - and I use large earbuds. - They isolate external noise like any other silicone earplugs. They are very comfortable because the tips are not only flexible but also adjust to the angle of the ear canal. Today I wore them for 3 hours with no discomfort in my ears. - They are reliable - today it was 90 degrees and I had several hours of sweaty work in the yard - during this time they did not move at all. - Price. They cost half the price of competitor foam tips and last longer because of the material. Cons: None yet. I will update my review and rating if any cons come up. Additional Notes: It looks like the SpinFits are grouped in 2 sizes - the ones I ordered were MEDIUM/LARGE, there is also a LARGE/LARGE. It would be nice if they sold the kit in S/M/L/XL sizes for guessing as some IEMs sit further into the ear than others so sometimes you end up with different sizes for different IEMs. However, on the Jabra 75t at least, the diameter of the spinfits matches that of the Jabra, so you can quickly find the right size. For Jabra, these are the earbuds to pack with your 75t. Do it better! UPDATE - 10 MONTHS LATER I'm still using the same tips on my 75t. No issues to report - they have held up and look exactly the same when I received them. I took them off a couple of times to clean them. These tips are worth their money.
