The Dell Slim Soundbar SB521A adds USB audio to a desk setup with a compact speaker designed for use with select Dell monitors. Its manufacturer part number is 8778K.
The soundbar connects and draws power through USB. Dell specifies 3.60 W RMS output and a frequency response from 180 Hz to 20 kHz, providing a simple audio option for everyday computer use.
Its magnetic attachment fits select Dell monitors, while the cable connects to a USB-A port on the monitor. This keeps the soundbar positioned with the display and avoids a separate power cable. The package includes the soundbar, a security chain and documentation.
