Key Features

1. Bluetooth 5.4 Technology

Bluetooth 5.4 provides the wireless connection standard used by the CM748. It is designed to support convenient connections with compatible Bluetooth accessories, including headphones, speakers, mice, keyboards and controllers.

Bluetooth 5.4 is backward-compatible with supported earlier Bluetooth devices, subject to the capabilities of the connected device and its profiles. citeturn371642search11

2. USB-A Plug-and-Play Design

The compact USB-A connector plugs directly into a compatible computer.

Windows 10, Windows 11 and Windows 8.1 are listed as supported systems, with Windows 7 requiring the appropriate driver. Setup requirements can vary by Windows version, so follow the supplied instructions. citeturn371642search0turn371642search11

3. Low-Latency Wireless Performance

The CM748 is marketed with a low-latency feature designed to support responsive wireless connections.

This can be useful for everyday audio playback and compatible peripherals. However, UGREEN does not publish a guaranteed end-to-end latency figure in milliseconds for this model, so performance may vary depending on the computer, headset and application. citeturn371642search0turn371642search8

4. Connect Multiple Device Types

The adapter is listed as supporting up to five connected device types. Compatible devices may include:

• Bluetooth headphones
• Wireless speakers
• Keyboards
• Mice
• Supported game controllers
• Other compatible Bluetooth peripherals

The ability to connect multiple devices does not mean that multiple audio sources can play through one adapter simultaneously. Actual operation depends on the supported profiles and Windows configuration.

5. Up to 20 Metres of Wireless Range

UGREEN lists a maximum range of up to 20 metres (approximately 66 feet) under unobstructed conditions.

Walls, furniture, nearby wireless equipment and the capabilities of the connected device can reduce the practical range. citeturn371642search0turn371642search9

6. LED Status Indicator

The built-in LED indicator provides a visual reference for the adapter’s operating status, helping you check its connection activity during use. citeturn371642search9

7. Compact and Lightweight

The CM748 has a small USB dongle design that occupies minimal space when connected to a computer. This makes it convenient for desktop setups, workstations and compatible laptops.

8. USB-Powered Operation

The adapter draws power from the connected computer’s USB port. It does not require an internal rechargeable battery or a separate power adapter. It is a computer Bluetooth adapter, not a standalone Bluetooth transmitter for televisions or AUX audio systems.
