I'm looking for a pair of wireless speakers but they have to fit the
following criteria:
1. operate with batteries (do any?).
2. will not interfere with my 900Mhz cordless phone or my 2.4Ghz
wireless network.
3. less than $100

do such things exist? will i have to spend over $100 for decent
speakers (I don't need anything spectacular, but good enough to run my
computers (2 of them), playstation, and TV through the stereo and be
happy enough with the sound quality)? I've got a selector switch that
I run all the devices through, so that's not a problem.
basically, I would like to find out if speakers that fit this criteria
exist and where I might be able to purchase them. And some kind of
idea that they are 'plug and play' if you will, that I can just plug
something into the speaker ports on the back of the stereo and that
they will work without much effort (I can build a computer from
scratch, but have no real experience with AV equipment, tho I'm
willing to experiment).

Any advice would be helpful, thanks.
