13 years ago I bought a Creative D100 speaker set (Bluetooth and/or hard-wired) that normally sold for $100. I got it for $45 in a clearance sale. I mostly use it hard-wired & mains-powered though, connected to an Airport Express. Prior to AirPlay, Apple had AirTunes which worked via the 3.5 mm stereo/optical port on AirPort Express routers.
