they have audio with ‘soothign soudns’
that is suppsoed to calm the mind and help with sleep- i haven’t tried them yet- so can’t say if they help or not
I rather go with my audio books since when my mind concentrates on what is being narrated I VERY SOON drift off. Works EVERY TIME.
Oh, I should mention that my King Size bed is also completely wired up. My control lets me move the area under the head and/or feet to any elevation desired. In addition I can flip on a wide variety of vibration modes with various frequencies, patterns, and intensities. My favorite is Earthquake mode. They all also help me sleep.
