Is there a way to make an Android phone (HTC Desire HD) act as Bluetooth speakers or headset?
I'd like to use the phone as wireless headphones whilst watching a movie on a computer (running Ubuntu).
As of right now the bluetooth API only supports pairing with the android device as the master. http://stackoverflow.com/questions/4474697/use-android-device-as-a-headset-for-another-device
This sort of functionality is often asked for, but as of yet I don't know of an application that actually does it!
Jamcast (http://www.sdstechnologies.com/) does what you ask, but they are currently still developing their Android app. http://www.sdstechnologies.com/Blog/post/Coming-Soon-Jamcast-for-Android.aspx
The good news is they are developing it though!
I must be missing something why do you want the phone to do it?
You'd be better off using a usb bluetooth chip(they cost less than £5) on your PC and a bluetooth Headset(I've got a superb one that lets me plug in any headphones I want,3.5 stereo jack so would take any little speakers as well).
Thank you for your interest in this question.
