Magic Sleep 1

Magic Sleep 1 instantly takes you to true sleep by making you breathe naturally.
 
Specific prerequisites must be met:
Keep yourself in a quiet area where you can hear only this sound.
Comfortably and easefully lie down.
Use high-definition headphones that have a good dynamic range and bass boost, like the Sennheiser HD 4.20s and the Sennheiser HD 300 Protect.
Use Windows Media Player Legacy, preferably without any effects, equalizers, enhancers, or similar.
You may appoint someone to take off your headphones once you have gone to sleep.
