This is a tiny little Bluetooth device that will allow you to send whatever audio signals you want to your sound system.
Imagine this if you will. You are a Hulu or Netflix owner that loves to watch it on your Android or Ipad Tablet. With this device you will be able to send the audio or sound signal of whatever you are watching to your closest stereo or computer speakers.
In other words, if you are watching the latest episode of The Newsroom on your Ipad, you will be able to listen to the episode you are watching on whatever speakers you have in your home.
