IMPORTANCE OF PROPER FIT
FIT THE HEADBAND
Proper fit is important both for comfort and optimal noise cancellation performance.
1. Using the left Tand right Uicons on the headband to orient the headset
properly, rotate the side pads into position.
2. Place the headset on your head.
3. Adjust the headband so the side pads rest above your ears.

CHOOSE THE CORRECT STAYHEAR+ TIPS
For optimal audio performance, it is important to choose the correct size
StayHear+ tip. Select the size that gives you the best comfort and fit in each ear.
To determine the best fit, you may need to try all three sizes. You may need a
dierent size for each ear.
NOTE: Without a properly fitting tip, the noise reduction and audio performance of
the headset will be degraded. To test the fit, try speaking aloud wearing the
headset while it’s powered o. Make a low-pitched “eee” sound. Your voice
should sound amplified and balanced in both ears, similar to when you plug
your ears with your fingers. If not, try another tip size.
Each StayHear+ tip and earbud is marked with either an Lor an R. Be sure to attach
the left tip to the left earbud and the right tip to the right earbud.
FIT THE EARBUDS TO YOUR EAR
The StayHear+ tip allows the earbud to rest comfortably and securely in your ear.
The tip wing fits just under your ear ridge.
1. Insert the earbud so the StayHear+ tip rests gently in the opening of the
ear canal.
2. Tilt the earbud back and tuck the tip wing under the ear ridge until it is secure.
TIP: If the StayHear+ tips don’t fit securely, choose a dierent size.

the tip wing.

ADJUST THE MICROPHONE
NOTE: By default, the reversible microphone ships from the factory attached to the
left side of the headset. If you want to move the microphone to the other side
of the headset, see “Microphone Placement” on page 26.
1. Grasp the microphone base, and adjust the boom so the microphone is level with
your mouth.
CAUTION: Microphone placement is important for clear communication.
It can rotate 300°. Do NOT force the microphone beyond the
intended rotation or damage could occur.
2. Position the microphone so it is 0.5" (12.7 mm) from your lips, and the white
surface on the base is facing your mouth.
NOTES:
• If necessary, twist the microphone base to rotate the microphone into position.
• The microphone should not be touching your lips.
3. Test the headset before flight.

CONDITIONS RELATED TO FIT
In very loud conditions, such as during takeo, 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 21. If it persists, see “Troubleshooting” on page 48.
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 16 for information on proper fit or “Clean the headset” on page 42 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.
