Similarities: they use the same microphone and earphone transducer. The headband and cushion are also the same. real differences: The -80 mike is mounted on a flexible gooseneck with the wiring inside it. It is supposed to be easier to adjust than the three-adjustment wire boom used on the other DC headsets. The stirrups that hold the earcups are different, resulting in less clamping pressure being applied to the head. This makes the headset more comfortable and reduces the attenuation by 3dB. (though I wonder if you couldn't get the same effect with one of the other headsets just by bending the headband spring a bit). The -80 is actually about 2 oz heavier. It has a volume control for each ear; the -40 has only a single control. cosmetic differences: Black paint on headband and mike boom on the -80 vs chrome on the other headsets. A thin layer of foam between your ear and the ear transducer. A new earmuff design. comment: If they were the same price, I would go for the -80 and try the new mike boom. But the price difference isn't justified to me.
