Converting wired surround sound system to wireless

[theapportioner]

Hi all,
 
I have some pretty decent wired speakers that I'd like to keep, but would also like to convert them to "wireless" using a bluetooth or some other sort of adaptor. Would love to hear what you all think are the best options. I have a 5.1 setup and would love to preserve that, only without the really long cords. Avoiding interference would be great too. Distance is not a major concern. Thanks!

You will either spend a small amount of money and wind up with some additional noise and lower audio bandwidth, or spend a lot of money and still have lower bandwidth, and, of course, you will not have wireless speakers in any event, you just will have traded audio wiring for a shorter wire to your nearest electrical outlet since, one way or another, you're going to have to power your speakers and it ain't going to be via batteries.
