The PX7 has excellent noise cancelling which is about as good as that of the Bose NC 700 but not the Sony XM3. The strap in back is too short. Came in a plastic baggy see picture not a box without invoice as the description says. Either too uncomfortable (adidas) or too flimsy (under armor) or cut into the skin on top of my feet (nike) or too stinky (pretty much every ?fancy? brand) Not these. A PESAR DE HABER CONCLUIDO EL PERIODO DE DEVOLUCIÓN ME HICIERON LA EFECTIVA Y ESTOY EN ESPERA DEL REEMBOLSO, GRACIAS I love this Gafa sandals, I have always wanted one and here it is! How can you not love a game with a roaming cow pooping on the board?! The bose app doesnt work well either. Either they sync beautifully straight away or one bud doesnt or goes off when its tapped and I cant restart. Lastly, my feet are on the skinny side, and these Sanuks don?t feel loose.
