UGREEN CM724 Bluetooth 5.0 Wireless Audio Receiver with 3.5mm AUX Jack

The UGREEN CM724 Bluetooth Wireless Audio Receiver has been designed to add convenient Bluetooth audio connectivity to devices equipped with a 3.5mm audio jack. Audio can be streamed wirelessly from a smartphone, tablet, or computer to compatible headphones, speakers, home audio systems, home theater systems, MP3 players, CD players, and other supported audio equipment. Bluetooth 5.0 technology is supported, while a wireless operating range of up to 10 meters is provided for flexible everyday use.

A built-in 300mAh Li-Ion rechargeable battery is included and provides up to 20 hours of operation on a full charge. A digital LED display is integrated to show important information, including volume, battery level, and connection status. Playback, volume adjustment, call management, and power can be controlled through the built-in multi-function buttons, allowing essential functions to be accessed directly from the receiver.

For added convenience, dual-device pairing is supported, allowing two Bluetooth devices to be connected simultaneously. Switching between a personal phone and a work phone can therefore be handled without repeated manual reconnection. A compact body measuring only 58 x 20 x 11 mm and weighing 20 g allows the receiver to be easily carried or installed with the included 3M adhesive tapes.

Important: The UGREEN CM724 is intended for Bluetooth audio reception. It cannot be used as a Wi-Fi/wireless network adapter and cannot be used to connect a keyboard or mouse.
