    Just got a David Clark One-X. When I first put it on, I thought felt a bit clampy so I decided to get some objective measurements.

    (clockwise from top left: Bose X, Bose A20, DC One-X, Lightspeed Zulu 3, Lightspeed QFR XC2, Lightspeed Sierra)

    I suspect that the pressure I felt was the memory foam. The first couple times I flew with the One-X, I thought they were pretty comfortable so it was probably the memory foam needing to be warmed up.

    While I had the scale out...

    And for reference, a passive DC H10-13.4 clone...

    You bring actual, objective data to an argument on POA? :incazzato:

    Infidel! Burn him!

    Besides, he didn't include a Halo in the test. :p

    Agree. It's troubling to think where this sort of deviant behaviour could lead. Someone might actually measure the shoulder width in a Mooney to prove it can carry two weight lifters. Or put a tape to the rear seat legroom in a Cherokee 140 to dispel the notion you have to amputate at the knees.

    This is the beginning of the end of PoA. It's been a good run folks.

    How are we to take data seriously if it's not presented in metric measurements? Was that scale manufacturer owned by or otherwise linked to any of the headset parent companies? And....what about the OP himself...what exactly is HIS relationship to these manufacturers, hMMMMMMMmMMMMmmmmmm?

    Seriously...thanks for the post. Interesting experiment. Still will never buy a Bose product, but that's a bias I bring with me from the audio world.

    Love it! @asicer's post should be sticky'd...somewhere.

    Just like your data...our one set of Bose A20 definitely do not clamp as tight as our Zulu 3's and thus why they just don't work for me in the 182. A slight turn of the head its full bore Conti power directly to the ear drums. The Zulu's never do that for me or my wife or daughter. But the Zulu 3's definitely feel heavier.
