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.

Single earbud use
When you want to use the headset with one earbud, you can stow the other earbud
using the earbud storage hook on the back of the side pad.
Earbud storage hook
CHANGE THE STAYHEAR+ TIPS
1. Holding the earbud, gently grasp the attached StayHear+ tip and peel it away from
the earbud.
CAUTION: To prevent tearing, grasp the StayHear+ tip by its base. Do NOT pull on
the tip wing.

2. Align the opening of the new StayHear+ tip with the earbud nozzle and rotate the
tip onto the nozzle. Press the base of the tip until it clicks securely into place.

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.

IMPORTANCE OF PROPER FIT
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.
SECURE CLOTHING CLIP AND CONTROL
MODULE HOLDER
The cable clips and control module holder secure the cable and control module to
your clothing, a safety harness, sun visor rail, or aircraft headset hook for quick and
easy access.

ACOUSTIC NOISE CANCELLATION
Acoustic Noise Cancellation reduces unwanted noise providing a clearer, more lifelike
audio performance. You can choose your noise cancellation based on your listening
preferences and environment.
NOTE: When you receive a call, the headset remains at the current noise
cancellation level.
ACOUSTIC NOISE CANCELLING FUNCTIONS
The Acoustic Noise Cancelling switch is located on the front of the control module.
Acoustic Noise Cancelling switch
FUNCTION POSITION DESCRIPTION
High
Maximum quiet and noise cancellation across the entire
spectrum. Best signal-to-noise ratio for radio and intercom
communications in loud aircraft.
Medium
Consistent noise reduction across a wide range of
frequencies. Best for clear and comfortable noise cancellation
in typical jet aircraft.
Low
Best for improved interpersonal communication outside of
the intercom.

ACOUSTIC NOISE CANCELLATION
TAP CONTROL FOR TALK-THROUGH COMMUNICATION
When you need to focus on interpersonal communication coming from a specific
direction, you can automatically set noise cancelling to Low on a single earbud by
firmly double-tapping the earbud.
NOTES:
• By default, Tap Control is set to O.
• Tap Control is available only when the Acoustic Noise Cancelling switch is in the
High or Medium position.
1. Make sure the Acoustic Noise Cancelling switch is in the High or Medium position.
2. Set the Tap Control switch to On.
See “Change the operation switches” on page 24.
3. Firmly double-tap the earbud.

NOTE: Tap Control is not a touch control feature. You must firmly double-tap the
earbud in order to activate the feature.
Reset Tap Control
To reset Tap Control and set noise cancelling in both earbuds to the Acoustic Noise
Cancelling switch level, double-tap the earbud with Tap Control active or move the
switch to another position.
