Those speakers look nice, but not as good as the Z series of the same model I don't believe.
Since there are no real audio jacks, I'd suggest you go and get a USB sound card device, and this'll plug into your laptop. You can then plug the speakers in the link in, if you decided to buy them
This for an example:
Since its also got a true 5.1 output on this sound card, your speakers will be given a good work out.
If you only used a headphone jack, you are more likely to get really messy sound using speakers, and just using one output, some of the speakers probably wouldn't work anyway.
I hope this helps.
