If this continues when the sound level returns to normal, see "Acoustic Noise Cancellation" on page 20. If it persists, see "Troubleshooting" on page 47. A low rumbling sound or frequent, brief losses of noise cancellation may indicate an improper fit or blocked earbud ports.

IMPORTANCE OF PROPER FIT
CONDITIONS RELATED TO FIT
In very loud conditions, such as during takeoff, you may experience a brief reduction
in noise cancellation as the headset compensates for a momentary pressure
change. If this continues when the sound level returns to normal, see “Acoustic Noise
Cancellation” on page 20. If it persists, see “Troubleshooting” on page 47.
A low rumbling sound or frequent, brief losses of noise cancellation may indicate
an improper fit or blocked earbud ports. See “Choose the correct StayHear+ tips” on
page 15 for information on proper fit or “Clean the headset” on page 41 for
instructions on removing blockages.
During a long flight, you may feel a slight pressure point, which can be relieved by
adjusting the headband position.
