Beep

Just because you want to listen to music wirelessly around your home or apartment, doesn't mean you need to go and replace all the speakers you've accumulated over the years. With Beep — a small Wi-Fi enabled device that connects to any stereo or speaker system with an RCA jack, auxiliary input, or optical input — you can play music to any connected speaker or group of speakers from your iOS or Android phone. With the ability to synchronize music across a range of Beeps, you can play your music throughout your place, or choose different music for different Beeps. While it only currently has built in support for Pandora, plenty of other app support is on its way.
