I am enjoying the tips. It mates my ears and the iems perfectly. It's an upgrade for any default eartips that comes along with the iem. Light weight and very comfort that you won't feel anything even if you listen for long hours

I'm very happy to review for this Spinfit CP-145. Present I'm using with JVC HA FW 01 IEM. I'm searched and tried so many eartips for this IEM. But this Spinfit CP 145 eartips was ends my searching. This is out of the world rendering the sounds and instruments separation is so crystal clear. I also using with Radissone HE100 earphone. This is also sounds so good and totally different from stock tips. That's why I'm calling it as Boss of Eartips For IEMs.
