For those about to rock, Altec Lansing’s inAir 5000 is a glorious set of AirPlay speakers. Setup is easy. Download a free app for your iOS device, plug that in to the speaker, and walk through the couple of steps it takes to name the device and connect it to your Wi-Fi network. You can also configure it by connecting to a network it creates temporarily through a browser on your computer, or using WPS on supported routers. You can then send music wirelessly straight from an iOS device running iOS 4.2—which can only stream to one speaker at a time—or by streaming music to one or more speakers from iTunes on your Mac or PC.
