I measure at a 7 exactly but needed the extra room of a 7. I never wear slippers. Solo como comentario al configurar la barra de sonido con la aplicacion puedes escoger con que asistente trabajar GOOGLE O ALEXA I use these headphones maybe once every few days, and they are stored in the carrying pouch that Betron provided in the packaging when not in use. I dont cringe as I would have with a naked buds live case. The instructions were very simple, the bluetooth connection to her iPad and her phone was very easy no issues of "searching for device"It was picked instantly and connectted. It?s not pzoz brand and looks nothing like the one showcased in photos. The case has internal texturing to prevent this very thing. Im sorry to say I do not recommend this product. They offered excellent shock absorbtion.
