Emotional healing V4 Journal~ Let the healing begin

[Shannon]

We don't recommend ultrasonic with headphones as it's too easy to mess up the volume. Too low reduces effectiveness, too high may damage hearing.

As for listening, why not listen at night while in bed on speakers? That's what I usually do, at first it can be a little hard to sleep but usually I adjust to it.

What if you have to leave the room during the run? Wont it break ASRB?

Yes, which is why I suggest always using it on a portable player, like a phone or mp3 player.
