Logitech Z120 — Simple, USB-Powered Stereo Sound for Your Workspace
The Logitech Z120 is the perfect audio solution for minimalists and professionals who need clear stereo sound without the clutter of extra power cables.

Despite their small footprint, they deliver surprisingly crisp sound for video calls, podcasts, and casual music listening.
Designed for ease of use, the Z120 features an integrated power and volume knob on the right speaker, giving you instant control over your audio levels. One of its most practical features is the cable management system at the back, which allows you to hide excess wire lengths, keeping your Lviv home office or workspace clean and organized. As a true Plug-and-Play device, it requires no specialized drivers, working instantly across all modern operating systems.

? FAQ
Why is there a buzzing sound coming from my Z120?
Buzzing or humming usually occurs due to an “electrical ground loop.” This can happen if the USB power and the 3.5mm jack are plugged into different devices. Try plugging both cables into the same computer, or move the USB power cable from a wall adapter directly to your PC’s USB port.
Can I use these speakers with my smartphone?
Yes, but the Z120 requires a USB power source to function. You can plug the 3.5mm jack into your phone (using a dongle if necessary) and the USB cable into a power bank, a wall charger, or a laptop to provide power to the speakers.
How long are the cables on the Z120?
The USB and 3.5mm cables are approximately 1.2 meters (3.9 feet) long. The cable connecting the two speakers to each other is also roughly 1.2 meters, allowing you to space them appropriately on either side of a large monitor or laptop.
