They work exactly like they said they would. They are very quick to switch on when you remove them from the charging case. They sound really good and have an awesome range. The bass is lacking though. They sound awesome for blues and jazz, but not ideal for rap or rock. The buttons are responsive and easy to use. They are quite comfortable, but I find that they fall out during a light jog. Love that you can use one at a time (either one so you can switch if you take really long phone meetings). The mic pickup is very good. Battery life is as it says on the box.
