BT have just launched a cool viral game to promote their VoIP product, Softphone with hi definition sound. The idea of the campaign is to demonstrate how good the voice quality is.

To play the Hi-Def Chamber you need a microphone. The object of the game is to break a wine glass with your voice, by holding a note for 20 seconds. To do this requires perfect pitch and clarity.

I didn’t even try as I can’t sing for toffee, but maybe you’ll do better than me.

Enter the Hi-Def Chamber now!
