On the lowest volume possible, resting with your eyes closed or while sleeping. So that you don't disturb yourself or your partner, put your device on your bedside table at just a whisper volume. If this still disturbs your sleeping, pop your device on the floor next to your bed. The Positive Auditory Stimuli Technique used in your audios works on subliminal programming, so you only need to barely hear the wording for it to give you maximum results.
