I use the sound therapy all the time. It has several different sounds to choose from and there are other sound cards available too. It is small and compact. I love it!
This is such an awesome teeny tiny speaker. I was kinda blown away by the sound quality of such a little speaker! The white noise sounds that come included on the SD card are very lovely and definitely will lull you to sleep, or at least put your mind at ease. The bluetooth speaker capability is pretty awesome too, worked really well! Since I keep this in the same spot everyday I just bought a simple USB plug in wall charger so that I never have to worry about it running out of juice :)
Bought this one for my daughter because she loves the one I got from the VA for tinitis. I've been using it for years, and on the right channel (pre-recorded) and my downloads, it outdoes any other system I've ever had. Daughter borrowed mine while I was away on vacation, and she swears it helped her sleep!
