can not be installed First order was lost Amazon made good w/credit. Works freat Excelente producto de muy buena calidad. They are not solid and removing the cap reveals the hollow inner middle. Muy mala calidad se rompieron en la primera semana I personally dont like like any type leather touching my ears, Ive been more inclined to cloth or velour pads. The polished white is simple and classic; both the earbuds and the case look and feel just the way I wanted. Will not buy this brand again. I wear them for gardening now when it is not hot outside.
