This one has lasted 10 months. Estos headset Sony suenan muy bien, la conectividad Bluetooth no se corta y la batería dura por lo menos 2 semanas con un uso de por lo menos 3 horas diarias. In the move of rooms somehow the ones i had were misplaced. (I measured sole and toe box, -which is where fit feels too snug. The ambient noise is well shielded and I can stay focused. We thought they were black but they are a dark blue and they fit perfectly so she happy and so am I. I’m not going to sugar coat this-I thought these were going to be hideous, uncomfortable pieces of garbage. I can’t even use it. I usually wear size 11, but I bought size 12, and the fit is perfect - anything smaller would be too short. Seek out in the snow to take the garbage out and still my toes are happy.
