Compact stereo speakers for desktop use

The Bingxue H21 is a 2.0 channel speaker system rated at 9 watts total power. It connects through a 3.5 mm audio jack and draws power from a 5 volt USB port. The pair is finished in black and weighs .72 kilograms, making it a simple audio upgrade for laptops, desktops or tablets.

USB power and 3.5 mm audio only

No external power brick is required; the speakers run from any standard USB-A port. A 47 inch cable links the two satellites so they can flank a monitor. Touch controls on the unit adjust volume from minimum to maximum. The system needs a device with both a USB port and a 3.5 mm output, or a suitable adapter for USB-C only devices.

Replaces basic monitor or laptop speakers

The 150 Hz to 20 KHz frequency response and 88 dB signal-to-noise ratio improve clarity over most built-in drivers. The jump is worth it when you want louder, fuller sound for music, films or games without adding a subwoofer or a separate amplifier. Buyers who need deep bass extension, wireless streaming or a dedicated headphone jack should look elsewhere.

Questions about this item

Will the 9 W output stay clean during long gaming sessions?

The speakers deliver 9 W total power with a frequency response up to 20 KHz and a signal-to-noise ratio of 88 dB, so output remains consistent during extended use.

How much heat or fan noise do the USB-powered units produce after hours of playback?

The system draws 5 V over USB with no internal fan, so it runs silently and generates only minimal warmth even during all-day operation.

My laptop only has USB-C ports — what adapter or cable do I need before these speakers will work?

You will need a USB-C to USB-A adapter for the power cable and a standard 3.5 mm audio jack or USB-C to 3.5 mm dongle for the audio connection.
