Compact Sound Bar for Desktop and Laptop

The Jeecoo A40 is a 16.5in USB-powered sound bar that delivers 10W of audio through dual 5W full-range drivers. It connects to PCs, laptops, smartphones or tablets using the included USB-C adapter and a 4.9ft cable. A single rotary knob controls volume, power and the switch between wired and Bluetooth modes.

Consistent Output During Extended Sessions

Rubber diaphragms help the drivers maintain clarity across games, music, videos and movies without the harshness that can appear after long playback. The USB connection supplies steady power so the 10W output does not dip when the source device reduces port current. Four LED lighting modes run independently of the audio signal and remember the last setting after a power cycle.

Plug-and-Play Setup with Minimal Friction

No drivers are required; the bar appears as a standard USB audio device on Windows and Mac once the cable is seated firmly. Bluetooth pairing is initiated by pressing the knob until the indicator flashes, then selecting "A40" on the host device. The most common issue is low volume caused by the host mixer or media player being muted, which is resolved by raising each level in turn.

Questions about this item

Does the 10W sound bar run warm or draw much power during all-day use?

The unit is USB-powered and rated at 10W total output, so it draws modest current from the host port and stays cool during extended sessions.

What port must my computer have so the USB-C adapter works without extra hubs?

A free USB-A or USB-C port supplies both power and audio; the included adapter lets you plug the 4.9 ft cable into either type.

Will the Bluetooth mode stay paired with my phone while the bar is plugged into an older desktop?

Yes — the bar needs USB power from the desktop, then a click of the knob switches to Bluetooth so the phone can pair to "A40" while the PC remains connected.
