Ideally listen to the Paraliminals in a time and place when you won't be disturbed. They have an entrainment sound track so I don't recommend listening at a time your concentration is needed on the job at hand. Certainly not when driving or using machinery.
After you've experienced the full sessions you can enjoy listening to them in the background. However if you want real benefits listen to the full sessions at a time you can relax and won't be disturbed.
