En comparación con las originales, son mucho más pequeñas (tamaño L). Por tanto no cubre muy bien el oido, el material no es de tan buena calidad, tienen poco espesor y tarda mucho en regresar a su forma original si se presiona. No es tan recomendable si se quisiera algo como los originales.

Súper duradero y muy cómodo. Si les untas algo crema duran mas

Ligeramente más pequeña que las que trae los xm3, muy contento que cierra la caja de los audífonos sin que quede ligeramente abierto

Leider passt mir die Ohrstöpsel nicht so gut bin daher beim Original geblieben, aber die Qualität scheint ok zu sein.

Image shows all. I use 1 large and 1 medium. They get gummed up with ear wax. I cleaned with isopropyl alcohol before I read on Sony web site NOT to use that!Used large and used med are in the photo; you can see they are kind of eaten away. So I bought them again. Just placed second large and second medium, so now's the time to get more (backup parts).Note that the small ones are 'clean' - they don't fit my ears.Last note: after they get a bit dirty, they fall out of your ears! You won't even notice some of the time. This is really painful when you spent $300+ and you can't just replace either the left or the right. Lesson? Clean 'em often. Or buy more of these replacements and cycle through them 'regularly' (i.e., monthly, not twice a year...).
