Logitech S150 2.0 USB Speakers 1.2 W RMS

Compact stereo speakers for desktop use

The Logitech S150 is a 2.0 speaker set that delivers 1.2 watts RMS of balanced audio from two lightweight satellites. Each unit measures 2.52 by 2.68 by 6.22 inches and weighs 0.481 kilograms total. The black finish suits office or home desks where space is limited. Power and audio travel over a single USB-A connection with no external adapter required.

Check USB-A port and power budget before ordering

Your computer must provide a free USB-A port capable of supplying 5 volts DC for both signal and power. The system draws up to 90 watts peak from the port, so verify the host can sustain that load without throttling. No RCA audio cable is used despite the connector type listed; the USB link handles everything. Ensure the operating system recognises USB audio class devices.

Steady output stays consistent during long sessions

The 1.2 watts RMS rating reflects continuous power rather than a short burst, so volume and clarity remain stable through extended playback. An orange LED on the right satellite confirms the system is active while the USB connection persists. Touch controls on the front adjust volume or mute instantly without software latency. The slim cabinets dissipate heat passively, avoiding fan noise during sustained use.
