UGREEN CM723 Bluetooth 5.4 Audio Receiver (USB + 3.5mm), black

The compact UGREEN CM723 Bluetooth receiver converts any AUX‑input speaker or car stereo into a wireless audio source: plug the USB‑A connector for power and insert the 3.5 mm jack into the device input. Running Bluetooth 5.4, it’s designed for wireless music streaming and hands‑free calls — suitable for cars, home audio systems or speakers without native Bluetooth.

CM723 supports common Bluetooth audio profiles (A2DP, AVRCP, HSP, HFP) and the SBC codec, features a built‑in microphone for calls, a multifunction control button and an LED indicator. The unit uses a nylon‑braided cable and a long lead for easy installation in a vehicle or connection to stationary amplifiers, while its compact shape keeps it unobtrusive.
