Just another user here. So for what it's worth:
a) you can listen anyway you want, it's yours!

But seriously...
b) You get a lot more of the Paraliminal effect (even while sleeping), with headphones and really isolating what part of your brain is hearing each side. I know, because I tried it using speakers and I did not get the kind of meditating effect of the Paraliminal (and this was even before the Holosync was added, I think because it was a few years ago and it was on cassette!)
It is highly recommended by Paul Scheele, by LS, by their coaches and by at least this user to use headphones when listening to Paraliminals both while awake or via sleep learing.
Hope that helps.
All the best,
Steve

While listening to the paraliminals while sleeping, are you supposed to keep your headphones on or can you just listen to it thru the speakers with the volume low???????
