Shannon's OF 5.75G Experience

[fab10]

Are you guys playing the ultrasonic track on a phone that is capable of reproducing the audio stereo, or?
@Shannon what phone model do you use?

At night I plug my phone into those cheap but decent stereo speakers normally used for PCs. It’s undoubtedly better than a phone speaker and it’s stereo. I put one on each side of the pillow and I am good to go. Just an idea. 

For additional comfort, since the setup made a slight buzzing sound after the sub was done, I programmed a smart socket to switch off on a timer.
