Two ads for a two-minute video? Hard pass. 

Pretty sure I already know:

A) they are acoustically a real thing with headphones, but 
B) their alleged New Age significances with clickbait all over YouTube lack peer-reviewed case reports, cohorts, and/or studies.
Close! 😉
(And yes, 2 forced ads at the beginning of every video now ... ugh)
