SpinFit - CP240

Great fit and sound quality. I only wish they came in Black Color, but that's not a deal-breaker in any way. Thanks HPZ for the super fast and efficient delivery :)

I'm no expert so i may be wrong but i think when i used these spin fits with my blon,the sound changed..mainly the bass, it became less...im now using my rha eartips with my blon ,apart from that these spinfits fit and isolate good i think.

if you understand how to use it, you will get the best out of it. First I ended up almost squeezing it and locking inside my ears (LOL). The trick is you need to just establish the correct positioning with the ear tips, i.e. insert it a bit deeper later lightly pull back don't fully pull out. Keep playing music while you are doing so when you hear the best output from the ear tips while positioning the ear tips - that the spot(wink).

Would review the product once I receive it. . .

These just stuffed my ear with silicon and they degrade the sound from xyz to a straight line.
I can see why that 1% of the crowd would want to buy it but everybody else, pick anything. Not these.

Fits perfectly

Spinfit is the perfect patner for my earphones

I got these for my new pair of Astell&Kern Billie Jean. My ear canals are pretty narrow, so the original tips didn't fit well. These ones however provide a perfect fit, very good seal. It should be noted though that they are a little bit too wide for the nozzles, so I had to add some non-permanent glue (from Scotch tape!) for added friction.

For sound isolation and quality. Build quality is also great.
