Someone just showed me this really exciting video.
How it works:
1) Make sure you are in a quiet room
2) Put on your functioning earphones/headphones on your ears
3) Turn the volume up a little bit
4) Close your eyes and just listen to the impressive audio...
Listen to the last minute. You're not going to believe how REAL it can be;)
