I just read an article on Webtrickz, I tried it and really impressed to use my Samsung Galaxy S2 as a wireless speaker. This is really easy to setup and the sound clarity is also good. You can also use a headset on your phone too.
Here is how to set up
1. Download the software for your computer and install it from GeorgieLabs
2. Install the android application on your phone from Google Play Store (Free)
3. Open the server application on the computer
4. Open the Android application and enter the server address on the text box (or you may choose auto select), connect using the image
5. Just play the audio on the computer the sound will be played on your android phone.
I tried from both Windows 8 and Windows 7 both worked fine for me. If you use a headset the sound clarity is really good.
