Very effective. Very stylish and comfortable! But I can?t wear them. These are not UGGs so dont expect them to be is all I have to say about whiners. They did not sound as rich as the Beats, but it wasn?t horribly noticeable. The velour fabric is really nice to have over your head for long period of time. Fifteen apps did not copy to this phone from my previous Android 9 phone. A slight learning curve, but definitely a keeper once get the hang of them. However, the leather was already damaged when I opened the box. Comprei o Mouse Pad Gamer Logitech G640 Hard em maio para usar com meu mouse Logitech G403.
