I don't know much about home theater equipment, so be gentle with me.

I wanted to get my parents some nice speakers for xmas for the dining room and living room in their house, but running speaker cable all the way across the house from the receiver will be a huge pain in the arse. Are there any good wireless speakers out there? They don't need huge speakers because the rooms aren't giant, but somehting that ill give them good, reliable sound during dinner parties and such. Are wireless speakers worth it or should I be good son and put in the effort to run cable all the way around the house? I looked on Best Buys website and that was no help. They only had generic looking crap. Thanks for the input.
