We highly recommend wearing headphones or earbuds to get the full effect. The binaural beats that are recorded in the background that place you in a relaxed hypnotic state would not be effective otherwise.
You can listen to our Subliminals during the day without headphones if you desire. Your subconscious mind will still pick up on the affirmations and absorb them.
While not as effective as wearing headphones or earbuds they will still work.
