WiFi2HiFi streams music over a Wireless LAN to your iOS device
Granted, you could just invest in a super-long audio cable, but where's the fun in that? It's 2011, after all, and everything in our lives deserves to be free of wires. Beyond being a wireless solution, WiFi2HiFi enables a truly remote wireless audio system, so you don't have to fumble with speaker dock remotes, or get up from the couch.
“The WiFi2HiFi application brings a world of music from your computer to your living room negating the need for an expensive audio streaming box,” said Tobias Gemperli with Clever & Son. If you want to take a look at the interface, check out the WiFi2HiFi website, and download the desktop program for free. And when you're convinced, you can find WiFi2HiFi in the iTunes Store for US$0.99.
