Our QuietComfort

headphones, including QC

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.
