Casio WU-BT10 Wireless Bluetooth MIDI and Audio Adapter for Select Casio Keyboards

The Casio WU-BT10 is a Bluetooth MIDI and audio adapter that connects to your keyboard's USB Type-A port and gives your instrument the ability to send and receive MIDI data wirelessly to and from other Bluetooth-MIDI-compatible gear. It also allows you to play Bluetooth audio on your keyboard's built-in speaker system. The WU-BT10 does not require additional batteries or a separate AC adapter, instead it draws power from the host keyboard's USB port.
