Allow me to clarify a bit.
Volumes are relative on portable devices, so 25% or less really isn't a good guideline, and I did not know that at the time. I now recommend that if you use ultrasonics with headphones, you use it at the lowest volume you can hear audible sounds. I recommend even more that you don't use ultrasonics with headphones.
One of the advantages of ultrasonics is the volume increase. But with headphones, we have no way of knowing how such direct audio is affecting you at a volume you might otherwise be used to using. So, we must play it safe. Very low volumes still work, as is evidenced by masked tracks.
