Forums IMPORTANT: PLEASE READ Paraliminals, Paraliminal Resets, Paraliminal Walkabouts, Natural Brilliance, Sonic Access Active Noise-Cancelling Headphones

Thanks uniquesoul. I guess earbuds are my only option, although I have tried a variety. It is loud on those smaller aircraft flights!
The noise cancelling frequencies the headphones emit are supposed to cancel out the outside of headphones noise, ambient noise, rather than the audio program. But, I suppose you are right in that they may disrupt the holosync feature.
