Android: Apple's media-streaming technology, AirPlay, is designed to stream only to "Apple approved" devices, but Android users can get around this by restriction with Android HIFI. The free app turns your Android device into a receiver for streaming music from AirPlay clients like iTunes and iOS.
Android HIFI, a.k.a. HIFISpeaker when it's installed on your device, is a no-frills app. There are few settings except choosing whether or not to keep your screen on. All you have to do is turn on iTunes, select Android HIFI as the speakers, and open the Android app. Both devices need to be on the same wireless network.
The app has a couple of useful features, such as adjusting the delay, auto-muting when there's an incoming call, and auto-lowering the volume if your headset is unplugged or your Bluetooth device is disconnected.
It's similar to previously mentioned AirBubble. Although Android HIFI has fewer settings, the app is completely free (as opposed to $US1.99 for the full AirBubble licence), and I found it played with fewer interruptions than AirBubble.
