Microlab B51 USB Power Speaker

The Microlab B51 is a compact, ultra-portable 2.0 channel stereo multimedia speaker system specifically engineered for users on the move. Drawing inspiration from modern soundbar designs, it features a slender, space-saving profile that acts as an immediate acoustic upgrade for laptops, tablets, smartphones, and desktop monitors.

Equipped with a unique mechanical clamp mount on the back, the B51 firmly grasps onto the top or edge of an LCD screen or laptop bezel. This clever, unintrusive design lifts the speaker off the desk entirely, making it an excellent choice for minimal workspaces, crowded student desks, and mobile workstations.

Audio performance is driven by two high-quality, 1.5-inch full-range speaker drivers that output a total of 4W RMS (2W x 2). Optimized to isolate ambient noise and reduce internal casing resonance, it delivers clean stereo separation, crisp vocals, and balanced mids that dramatically outclass standard built-in laptop audio. Additionally, the drivers are magnetically shielded to guarantee distortion-free and static-free positioning right next to sensitive computer monitors and electronics.

Operation is streamlined through a straightforward plug-and-play setup requiring no software drivers. It draws all its electricity directly via an attached USB cable (5V/2A), eliminating the need for internal batteries or bulky wall power bricks. Audio is transmitted via a universal 3.5mm stereo line-in cable, allowing it to connect to nearly any media player. Top-panel controls feature an integrated volume dial, a clear LED power indicator, and a dedicated power switch for fast, tactile adjustments right at your fingertips.
