Just what am I supposed to do, am deaf in one ear ( :
If you have total hearing loss in one ear, unfortunately you won't be able to get the binaural effect. Some people say monaural beats are just as effective, though I haven't tried them myself. All you need to do is put your phone into "mono mode" in your device's settings (if you haven’t already done so) and the beat will be present in both left and right earpieces (whichever one you use).
