No need for fancy headphones with Paraliminals. The Holosync entrainment designed for Paraliminals don't use the deeper levels as the Centerpointe program. I've used the cheapest ones with good effect.

If the headphones are not stereo, you're missing out on the entrainment and deeper level of work that Paraliminals can do for you. Since the scripts are carefully crafted normal listening would yield some positive results. The idea of listening with headphones in stereo is so that the super-conscious mind does the work. By passing the critical and limited in information, tip of the iceberg, conscious mind.
