The Logitech V20s sound great. We played everything from Bach's Sonata No. 3 for violin and Arvo Pärt's "Dopo la Vittoria" for chorus to the French tango-electronica sounds of the Gotan Project's latest album, Lunático. Basses were deep and trebles were crisp without sounding like we were listening through a soup can. The speakers were also surprisingly loud and should have enough volume to fill almost any room.
Unlike most laptop speakers, which require heavy batteries or an additional AC adapter, the V20s use your notebook's USB port for both audio data and power. Being USB devices, the speakers also allow input; as such they have play/pause, stop, previous track, next track, mute, volume-up, and volume-down keys. Setup was straightforward. When we plugged the speakers into both a Windows XP and a Mac OS X laptop, they were immediately recognized by the OS and starting pumping out tunes. Mac users should note that while the volume controls work, the other multimedia buttons do not.
The speakers do have a few annoying flaws. The downside of the USB connection is the inability to connect the speakers to portable players or other devices, so no laptop, no joy. The Logitech V20 notebook speakers are so lightweight that at high volumes, they vibrate their way across a desk unless secured. Finally, when playing high-bass music or movies at near-maximum volumes, the Logitech V20 notebook speakers have a tendency to cut out, as the laptop's USB port simply can't provide them with enough power.
