USB Stereo Sound Bar

The Corn Electronics USB Sound Bar is a compact stereo speaker powered by a 5 V USB port and connected through a 3.5 mm audio jack. Its low-profile bar design sits under a monitor to save desk space and reduce cable clutter. No drivers or software are required, so it works immediately on any device with the matching ports. The 2021 version adds dual bass diaphragms and anti-magnetic shielding for cleaner output.

3.5 mm analogue input

The single specification that decides compatibility is the 3.5 mm audio input paired with USB power. The unit draws power from any standard USB-A port while receiving the audio signal through the analogue jack. If your source only offers HDMI, optical, Bluetooth or a USB-C audio path without an analogue output, this speaker will not connect without an adapter. The 3.5 mm plug is the only audio interface provided.

Buyers needing a simple wired desktop upgrade

This bar suits anyone who wants a space-saving, plug-and-play stereo upgrade for a PC, laptop, tablet, phone or projector that has a headphone jack and a spare USB port. It is not for users who require wireless streaming, surround sound, a built-in microphone, or higher output power than the USB bus can deliver. Buyers who need more connectivity options or louder room-filling volume should look at something else.
