Summary: I didn't expect the surround effects to be as good as they are. These deliver great sound on my desk without running a lot of cables everywhere. I am very discerning as to the sound of my music. These do a wonderful job with the Beats Audio system in my computer.
Summary: I had been looking at more expensive audio file speakers for my desk top, and figured why do I need audio file quality for my desk top. So I ordered these. I was amazed. They sound just as good as the Bose or Klipsch. They can play clearly at high and low volumes and have a minimum amount of distortion at higher volumes.
Summary: Best sounding desktop speakers I have ever heard. Razor sharp sound, very natural sounding voices in singing or speaking, no boominess, OK Bass, they have 3 inch (7.5cm) low frequency speakers and there is a limit to how low they can go. For desktop speakers, this is as good as it gets. They look and feel really high quality and modern. Very pleased with my purchase.
Summary: We have a slightly older Toshiba LCD TV on top of the fridge in our kitchen, and the internal speakers became intermittent. It's part of a bigger problem with the TV because simultaneously the TV became very difficult to power-up as well. Anyway, instead of junking a TV that still operates well enough, albeit without sound, I decided to add some speakers. I found a great price on these on Amazon and pulled the trigger.
Summary: I've been living with these speakers for the better part of a year now. In the interim, my PC of almost 10 years died on me. This has allowed me to gain several insights on this speaker set since I've had the hooked up to my old PC, amy laptop & my new PC. The most important thing a speaker can do is accurately portray what is being fed to it upstream. The Z520's do that in a wonderful fashion.
