Whilst you’re waiting to hear what our bro actually does, you might like to know that the Official Sapienmed FAQ (Updated) tells us it really doesn’t matter.
This is simply a matter of opinion.
You see, I’ve read that hormonal and audios which work on the physical body work better on speakers as the field can expand and affect more of our physical bodies, where those problems are manifesting. And I’m not saying this to get into a “He said…”/“She said…” sort of thing. My point here is, if there was a meaningful difference one way or another, the FAQ would say something different, right?
Don’t make perfect the enemy of good. That’ll really slow down your progress.
