English

– When the use of privately owned earphones is prohibited

inside the plane.

• The noise-canceller function is designed to reduce noise

primarily in the low-frequency range, and is not effective at

reducing high-frequency noise.

• If the earphone tips do not correctly match the size and

contours of your ears, excessive sound may escape, or you

may sense insufficient bass sound, and the effect of the

noise-canceling function may be reduced. Always select and

use the earphone tips that best match the size of your ears.

• If the earphones’ microphone is covered with your hand or

other object, feedback may be caused, resulting in a

“howling” sound. In this case, remove your hand or other

obstruction from the microphone.
