I still do not understand how they turn off when folded. Maybe I didn't understand something Some pros: Long work from one charge. Build quality and sound. With them, the wife fell in love with listening to music in general and during working hours in particular. Convenient for talking on the phone. Different cons: Connector for charging. It's a usb micro. I didn't expect it from Apple. Apparently they made a lot of headphones with this connector that came to life and are still selling
