probably, provided the headphones have a transmitter that accepts analog input.
if you intend to use the speaker outputs, you would need a line level adapter to reduce the power level before converting to the rca or 3.5mm input on a transmitter device. or, you likely could use the pre-out which should be low level before the amplifier.
kind of pointless to use wireless headphones with an amplifier unless you're using it for the radio or similar.
