Speakers for Gaming/ Music, and connection!

[SammyNib]

I'm looking to get some speakers for my gaming PC, I also use it for listening to music so I would like it to be good for that as well. I found this on Amazon and after looking at reviews they seem pretty good:

My only real issue is how do I connect them to my computer/ monitor. My monitor only has VGA and 3.5 mm in as well as DVI but that's what I'm using to connect it to my computer. I was wondering whether it is actually possible to connect them or not, like an additional cable is needed or something. Also if they are not usable with my set-up then could anyone recommend another speakers that would be usable for what I have, my budget is around £30-50.

Thanks for any help in advance.

They'll plug into the speaker/headphone jack on the back of your PC, pretty much every PC has one so don't worry about that. They use the same type of connector that a pair of headphones does.

Thanks for the help, from what I've read they seem like quite good speakers so now that I know they will connect fine I think they will be the ones to get.
