The headphones fold down nicely for storage, but they do not come with a storage bag/case of any type. There are buttons on the headphones for forward/back/pause, for volume control, for on/off and to bring up your voice assistant (Google/Alexa). Charging is done via a USB-C port, and a USB-A to USB-C charging cable is included.
