Not just another sleep app. Proper binaural recordings
Excellent binaural sounds. Make sure to get the rain and thunder tracks.
While they did remove the earbud optimization look to get a neutral pair of headphones. For in-ears look into Vsonic GR07. For over ear headphones check out Sennheiser HD598 or Phillips Fidelio X2. Want something really amazing look into Sennheiser HD650 or HD800. Using this app with an Audeze LCD2 and headphone amp and the detail and transients are amazing.
