create any "static" pressure in the earcups. We infrequently receive
reports from people who believe they are feeling some such pressure. The
only explanation we have is that the perceived sonic effect one hears
when wearing any well-performing ANR headphone – where the low-
frequency sound in one's environment is significantly reduced – also can
be caused when one's eardrums are under a pressure difference, which
can happen in a fast-moving elevator or a descending airplane. Some
people may associate this sound with a sense of pressure.
Airline travelers quickly learn to yawn or swallow to "pop" their ears when
the world sounds like this, as the plane ascends or descends. The sonic
effect of ANR, by reducing the low-frequency noise, can obscure this
trigger we've all learned, and you may feel some discomfort if you don't
"pop" your ears soon enough to avoid any discomfort. The first time of two
you fly with any of our QuietComfort headphones, pay particular
attention to swallowing early to equalize the pressure in your ears.
