Sharper Image SR288 ZipConnect 900MHz Wireless Outdoor Speakers with Docking Station
I bought these for my spa room.  I thought I would need 2, but the sound quality is so good that I am able to use the \\"spare\\" elsewhere.  The first couple of times, I had to fiddle a little bit with the receiver and speaker to get reception, but once I figured it out, they were very easy to use.  Worth the price, especially to get 2.
