I use a Sony MD player for listening. I copy the holosync dive + imersion onto the disk, then just the middle of the paraliminal. Since I am already in a relaxed state after Holosync, I skip the first part of the paraliminal that is talking you into a relaxed state. Also I cut out the end that is designed to bring you back up to a normal waking state. I do this because I listen right before I go to sleep at night.
