Second 3.5mm output?

[M0esmac]

Hi guys,
I want to ask, is there any solutions for second 3.5mm output?
I want to do a bit DJ stuff, and I want to output it to my 3.5mm speakers and headphones, headphones to listen before I let it on speakers. You know what I mean I hope.

Thanks

edit: I have 13" 2011 MBP

You can buy and USB audio interface that has any number of inputs and outputs. These are usually better quality then what is built into the computer. But most of these have "professional" style connectors on them so you would need an adaptor to get the 3.5mm size jack,

Look here for a few ideas:

They also sell specialized DJ controllers that maybe are more suited to your needs. These will have al the jacks and fader controls you need.
