Abstract
A case (100) is provided for housing and charging one or more wireless devices (180), such as wireless earbuds. The case (100) includes capacitive sensing circuitry (120) for detecting whether the wireless devices (180) are positioned inside the case (100) based on a capacitance of the wireless devices (180). The case (100) also includes a transceiver (150) for transmitting data to and receiving data from the wireless devices (180). When the wireless devices (180) are positioned inside the case (100), an electrical component (110) inside the case operatively connects the capacitive sensing circuitry (120) and the transceiver (150) of the case (100) to the wireless devices (180). The case (100) further includes one or more processors (140) for controlling the capacitive sensing circuitry (120), the transceiver (150), and the electrical component (110).
