I just bought a bluetooth audio receiver and you should too. It was about $40 (I won't add a link, there are many many different kinds out there).
It is absolute heaven to not be tied to our main house stereo with that damn headphone plug! I can zap audio from my iPod, mobile, any of the lappies and our main sit-down computer. For all that is holy in the world, go buy yourself one, you will not be sorry.
