On Track 1, verbal guidance relaxes you while Hemi-Sync® sound patterns guide you into a totally refreshing Delta sleep. Track 2 features soothing sound effects embedded with Hemi-Sync® to continue your deep sleep cycle. You may wish to experiment with each Track separately, or play the entire title continuously. Use ear buds, headphones or speakers placed on either side of the bed. (Track 1 – Verbal, voiced by Robert Monroe; Track 2 – Nonverbal)  Total length: 70 min.
