The infusable energies are weak subtle energies. Therefore the audio source needs to touch the bottle.
I have tried to infuse energies remotely, and more often than not, I failed...
So, what you do is play the audio as loud as you can, and place the headphones facing each other on the bottle that contains the water.
The larger the surface of the headphone speaker, the tighter the headphones are touching the bottle, and the louder the audio, the more energy will be infused into the water.
If you use earbuds, the time will be 10 times longer than if you use full size headphones.
If you play the audio AT the bottle, no energy will infuse.
