SpinFit is a patented ear tip. It has an ergonomic concave design at the core to allow the ear tip to swivel, making it flexible to bend and twist to the contour of a person’s ear canal. The flexible nature, easy swivel and attractive colour options make it stand out form the average silicone eartips.
SpinFit are made up of premium soft silicon material along with ergonomic design which provides supreme and long lasting comfort.
They have a consistent seal even for earphones with any insertion angle which gives the perfect noise isolation.
Simple installation makes SpinFit an easy upgrade for your earphone and hence, they become a perfect replacement for your ear tips.
Its enrichment on treble and bass ensures a superior listening experience to the foam and the ear tips.

SpinFit - CP500
Very well rendering for Bass and Treable. I'm using these with my RHA cl2 and JVC HA-FW01 IEMs. These are very good noise isolating and very good ear fit.
Having low tolerance for noise, I keep my ears plugged all the time. The KZ AS10 are perhaps the most isolating, budget earphones but its default silicone tips were quite hard and itchy. I was using my old Sony Hybrid eartips (comes default with their XB lineup) which were much softer but blocked some of the sound because of smaller opening. I wanted to go for the double flange CP240 for even more isolation but was worried it might not fit (base dia of only 4mm) so went for the CP500 (5.5mm base). Now it's just as comfortable as the Sonys but sounds more open. The seal is also a little better but not significantly so.
Now that I have determined the right size and am confident of the "comfort quotient" of Spinfits, I will get the CP230 Double flange (base 5.5mm) from AliExpress (or maybe here if they launch it at similar price) for finally achieving max silence in my day-to-day life!
Oh and 4 stars because the price a bit high (but totally worth it) :D
