Ma,I've got 4 sets of headphones,3 wired,1 wireless.
The best ones I have are the wireless($150)they put all external speakers to shame,BUT,they interfer with my wireless network! so I usually use a cheap pair of Panasonic headphones that came with the wifes portable CD player just to listen.
I'm looking at the new Bose(Noise Cacelling) headphones now.
Bummer about wireless conflicting with wireless. Good luck finding the proper solution.
