We suggest consulting a medical doctor for any pre-existing conditions prior to using the product. The best thing to do would be to ask your doctor if this technology would be good for you. (if they do not know about it you can ask about deep meditation)
Of course if you do try it and feel uncomfortable then stop immediately. When you start listening please use a low volume to start with and slowly work your way up as your system gets more used to this form of stimulation.
