Not trying to diss anyone's tech here, but until there's been scientific evidence to show that ADEL actually has, in a controlled study environment resulted in less noise induced hearing loss over a period of time, while APEX doesn't, I wouldn't refrain from making such claims.
Personally, the way I understand the ear, I don't quite buy into the idea. Having said that, I'm no expert and may very well be wrong.
Now if you personally find one tech to reduce listening fatigue or tinnitus or whatever it is over the other, then yes please feel free to go ahead and make that claim as brooko often does, I can't dispute that. He's not the only one, a couple of people have that experience. While I cannot quite fathom it, I respect that they know what they're experiencing, and if listening fatigue ever were a problem for someone, he or she should probably give them a go and see what happens.
But until there's proper scientific evidence stating that one actually objectively reduces hearing loss, not by inductive reasoning but rather by hard end evidence and the other doesn't, I wouldn't put it that way.
