This USB Bluetooth adapter model CM390 provides a straightforward way to add Bluetooth 5.0 functionality to computers and laptops that lack built-in wireless support. Whether you need to stream audio to wireless headphones, transfer files between devices, or connect peripherals such as keyboards and mice, this adapter enables those connections without internal hardware changes. With a transmission distance of up to 20 metres in a barrier-free environment, it offers practical range for most home or office setups. The adapter supports multiple Bluetooth protocols including A2DP, H2DP, HSP, AVRCP, and HID, ensuring broad compatibility with a variety of devices.

Features and Construction

The CM390 adapter is built around Bluetooth 5.0 technology, which provides efficient data transfer and stable connections. Its compact form factor makes it easy to carry or leave plugged into a USB port without obstructing adjacent ports.

Bluetooth 5.0 Version

Bluetooth 5.0 offers improvements over older versions in terms of data throughput and connection stability. This version supports the listed protocols and is suitable for audio streaming, peripheral communication, and data exchange tasks.

20 Metre Barrier-Free Range

The specified 20-metre transmission distance applies in barrier-free environments, meaning clear line of sight between the adapter and connected device. Walls or other obstacles may reduce effective range, but the adapter provides adequate coverage for typical room-sized areas.

Protocol Support

The adapter is compatible with A2DP (Advanced Audio Distribution Profile) for high-quality audio streaming, H2DP and HSP for headset and hands-free use, AVRCP for remote control of audio devices, and HID for human interface devices such as keyboards and mice. This range of protocols increases its usefulness across different applications.

Uses and Placement

This Bluetooth adapter is designed for plug-and-play operation with devices running compatible operating systems. Its small size means it can remain installed permanently or be moved between devices as needed.

Desktop Computer Upgrade

Adding Bluetooth to a desktop PC allows connection of wireless peripherals, speakers, and other devices without the clutter of cables. The adapter's compact package size of 114mm x 102mm x 8mm means it fits easily into a USB port on the front or back of the computer case.

Laptop Connectivity

Older laptops without built-in Bluetooth can gain wireless capability through this adapter. It is also useful for laptops whose internal Bluetooth module has failed, offering a simple external replacement. The adapter can be left plugged in during travel or removed and stored when not needed.

Home Office or Entertainment Setup

In a home office, the adapter can connect wireless speakers for music or conference calls. In an entertainment setup, it can stream audio from a PC to a Bluetooth soundbar or headphones. The 20-metre range allows flexibility in device placement within a room.

Benefits and Buying Value

This adapter provides an affordable way to add modern Bluetooth capability to existing devices without the expense of upgrading hardware. Its protocol support ensures it works with a wide array of Bluetooth accessories.

Easy Integration

No internal installation or technical expertise is required. Simply plug the adapter into a USB port, and the operating system should recognise it automatically (driver requirements are not specified in the source text). This simplicity saves time and avoids the need for professional installation.

Broad Device Compatibility

Support for A2DP, H2DP, HSP, AVRCP, and HID means the adapter can connect to wireless headphones, speakers, keyboards, mice, game controllers, and other Bluetooth peripherals. This versatility makes it useful for multiple scenarios without needing separate adapters for each device type.

Space-Saving Design

The adapter's small dimensions mean it adds minimal bulk to a computer setup. It can stay plugged in permanently without interfering with other USB devices, making it a practical choice for users who need consistent wireless connectivity.
