UGREEN CM748 USB Bluetooth 5.4 Adapter - Stable, Ultra-Fast Wireless Audio Connection

Plug-In Bluetooth for Any PC, No Drama

The UGREEN CM748 turns any Windows PC into a Bluetooth-ready machine in seconds. Built on Bluetooth 5.4, it delivers a noticeably more stable connection with less audio lag and dropouts than older adapters, and it can sync with up to five devices at once, so headphones, a keyboard, and a mouse can all stay paired without constant re-pairing.

Audio quality is a highlight here: the CM748 supports high-fidelity sound output for music and calls, with a transmission range of roughly 20 meters so you're not tied to your desk. Its compact, low-profile design fits into any USB-A port without blocking neighboring slots, making it easy to leave plugged in permanently.

Setup is plug-and-play on Windows 10 and 11 with no driver install needed (Windows 8.1 requires a free driver download). It is not compatible with macOS, Linux, car audio systems, or TV boxes, so it's best suited for a dedicated Windows desktop or laptop.
