The Logitech Z-4 Speaker System is simple plug in System that comes with 1 Subwoofer and 2 Speakers along with a dial to change the Sound and Bass. The dial is a big asset to the Speakers as you can change them as you dont always want a big Bass when watching T.V as when your listening to Music. The wires are a decent length but you will need extention cables if you want to lay the speakers out in the corners of your room. You wont need extensions if you are keeping them near what you are plugging it into.
They are not exactly the most stylish Speaker Systems around but for its price they are pretty good. The Subwoofer doesnt look to pleasant but i think the other Speakers that come with it are nice looking. From my search i have found the Z-4 only comes in black but there is a Z-4i that is in white but i think it costs £57.35 of Amazon but is only in the UK right now.
The set up is really simple, you just need to plug the speakers into your T.V, Computer, Labtop or Game Console. It is also worth mentioning that Logitech sell an adaptor should your TV not have the jack needed.
