Those aren't headphones are they? Shannon, doesn't recommend using headphones with the ultrasonic, esp. all night long. I use headphones only during the day if I need to. As for the volume, check it with the waves and/or a music track. As long as you can hear the lowest wave or music at a decent volume that's fine for the ultrasonic. Just not too loud.
