I have around 35 gig of Hemi-Sync, Holosync & Kelly Howell's Brain Sync.
I really enjoy using all of them for different purposes.
Hemi-Sync 'Meta-Music' is fantastic to listen to whilst reading.. Even though its very relaxing I maintain a high degree of focus and have increased mental stamina whilst also having that etheric trancendental feel to reality.
Im also keen on getting one of these-
