I got these speakers for my notebook. it has two 3.5mm audio output jacks so all the 4 speakers can be powered up without any other accessory.
it you want these speakers to connect yo a laptops with only one output you can buy a pin which could connect all the four speakers to work.
Probably you will not able to get the surround sound experience if you have not installed a sound card which supports 4.1
if we talk about value for money then the speakers are perfect for it.
the speakers are having very clear sound with deep bass
looks pretty good and the wired reomte is very useful.
