The case may seem a little big to some. It's probably a recharging charge. The right earpiece pressed a little at first, now it's normal. It is the main one, it can work when the left one is in the case, but not vice versa. Each has one button with different functions. On the right - pick up / hang up, play / pause, call an assistant. On the second - track change. The volume from them is not regulated, only from the device.
