Conclusion: The Logitech Z-5500 is the best all-around PC speaker system we have used to date. The sound quality is first-rate, the system looks stylish and the added features/decoders are merely frosting on the cake. Though the system is now slightly dated, the Z-5500 is that rare breed of gadget that, even when an update does come down the pipeline, we would not have any regrets having purchased.
Pros: Excellent sound; Plenty of power; THX certified; several processing modes
Cons: Lacks TrueHD and HDMI passthrough; minor design foibles
Conclusion: The Logitech Z-5500 Digital speaker system is a 5.1-channel behemoth that boasts a wealth of connectivity options and multi-channel effects. It's a perfect match for most game consoles, home theaters, and PCs—but its bombastic low end can become overbearing with certain types of source material.
Pros: Fearsome volume levels. Plugs directly into almost any analog or digital source. Deep bass. Outstanding tethered control pod and wireless remote.
Summary: If you need a great set of PC speakers for movies and games, then the Z5500s should be a prime candidate. For music lovers they may not be the first choice, but their strong performance all around means they cannot be ignored.
