I supplement after a couple of days of use: while you take out the headphones from the case, they somehow automatically turn on and connect to each other, and then to the phone. So they already turn out to be in their ears with music. But if one earpiece loses connection (due to a call, for example), then then connect them so that they work together, it’s like dancing with a tambourine, to put it mildly. You turn off / on the headphones, bluetooth, but they still work separately.
