Question to Shannon - Quality Earphone

[LionKing]

From my personal experience I have used earphones and headphones ... Mostly because by using the headphones, the subliminal is playing in both ears which allow you get to receive the full benefit of the subliminal.

I guess you meant speakers vs. head- or earphones? You should get the full stereo effect regardless whether you headphones are open, closed or in-ear, imo.

Btw, I'd think its less effective if you can hear the voices, simply because Shannon has intentionally set their volume so low you shouldn't be able to hear them, i.e. they're not meant to be heard consciously.
