Overview

The Logitech S150 USB Digital Speaker System is a compact stereo pair designed for desktop and laptop users who want straightforward, cable-minimal audio. The entire setup runs off a single USB-A connection — no 3.5mm audio cable, no power adapter, no driver installation. You plug them in, and they work. The integrated volume controls on the right speaker let you adjust output without alt-tabbing to software settings, and the slim profile keeps your desk uncluttered.

With 1.2 watts RMS of total output, the S150 is built for personal listening at arm's length rather than filling a room. It handles spoken content, system sounds, and background music clearly, though users looking for deep bass or high-volume performance will want to look at larger, powered alternatives. The 4-foot USB cable provides reasonable reach for most desk setups. As a budget-friendly, space-saving option for everyday computer audio, the S150 delivers reliable performance without unnecessary complexity.

Frequently Asked Questions

Do the Logitech S150 speakers require a separate power adapter?

No — the S150 speakers are powered entirely through the USB connection, so there is no need for an external power supply or wall outlet near your desk.

How do you control the volume on the S150?

The speakers have built-in volume controls located directly on the right speaker unit, allowing quick adjustments without reaching for on-screen software controls.

What is the audio output power of the S150?

The Logitech S150 delivers 1.2 watts RMS total output, which is sufficient for personal listening at a desk but not intended for filling a large room.

Do these speakers use a 3.5mm audio jack or USB for the audio signal?

The S150 uses a USB connection for both audio signal and power — there is no 3.5mm jack. This means they rely on digital USB audio rather than your computer's analog audio output.

How long is the cable on the S150?

The cable is 4 feet long, providing enough reach to connect to a desktop tower on or under a desk, though placement options are somewhat limited by that length.
