decent sound, bad fit in ears

Build Quality 4-5, Sound 4, Fit 3-4
I found the sound inferior to Apple For Example bundled earphones (last generation), it is not bad, but has less richness and bass. But the real problem is the fit. First a disclaimer, I did not wear in-ear earphones for a while, and maybe forgot thatthey are simply different the other earphones, more prone to sound quality changes due to dislocation. Anyway, in short, Whereas it is possible to fit them properly into the ear, They move out Easily, even during operation of the controls. The so called stabilizer does not function in my case at all, I do not see the point of having them as They change nothing. There are 3 different size of silicone cover but none of them helped to fit them better. I'm not saying the earphones are not good, I simply suggest to try them out before buying.
