If noise canceling designs have a built-in amp, are they designed to be used with a headphone jack or can they be used with an adjustable line-level? I assume a dedicated amp is not needed, but are there any known impedance considerations with feeding one line-level? Is the performance better? The same? Worse? How does such a design even deal with potentially extremely large inputs from a headphone amp? Do they have limiters?
