It features a screen and built-in battery. It allows you to make hands-free phone calls. The Bluetooth receiver is used to transfer sounds from Bluetooth devices (e.g. phone) to car speakers. The built-in battery allows for many hours of operation without a connected power source, while charging is done through the USB-C port.

The multi-function button allows you to handle all calls (answer, reject, end, and redial). The built-in microphone allows you to speak freely without needing to hold the phone in your hand. The media button allows you to answer/end calls, control music, and adjust the volume.
