SPeaker / Sound card purchase suggestions / help

[phiktion]

I'm looking for away to hook my keyboards output + my computers output, I currently use sepearate headphones for both and would like to be able to here both at the same time or just swap back and forth easier.

I have checked out a few studio monitors not sure if they have all the right plugs.

Not sure if I need a good sound card I currently have a pretty old sound blaster audigy 2zs which doesnt have the inputs or outputs I need for my keyboard.
