After a couple hours of using them I got use to it, but if you could find PTFE feet available, you may prefer those. Buena calidad y lindo diseño, pero muy estrechas, las pedí para mi mamá y no le quedaron de ancho, incluso a mi me quedaron justas de ancho You often find beads that are longer or shorter. You spend more, in the long run, that way. 8" and I have to pull so hard to make it work. I originally bought a 10 but that was still a little tight even after putting it on the last hole. There was definitely a learning curve with figuring out how to put them in my ears properly. Anyone that claims these are just as good as the originals are lying. Cute little dainty beads. Ill deal with the silicone ones not staying put over poor sound quality.
