NOTES:
There are two options for the control module:
Proper fit is important both for comfort and optimal noise cancellation performance.
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 different 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 off. 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 L or an R. Be sure to attach the left tip to the left earbud and the right tip to the right earbud.
The StayHear+ tip allows the earbud to rest comfortably and securely in your ear. The tip wing fits just under your ear ridge.
TIP: If the StayHear+ tips don't fit securely, choose a different size.
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.
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".
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". If it persists, see "Troubleshooting".
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" for information on proper fit or "Clean the headset" 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.
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.
Press the side button to release and reposition the clip along the cable.
Pull the strap over the control module to secure it in place.
Press the Power button .
The Power light glows amber then blinks according to the power level. See "Power light".
NOTE: The first time you power on your headset, noise cancellation is fully enabled. See "Acoustic Noise Cancellation".
Press and hold for three seconds, then release.
When powered off, the headset provides passive audio communications.
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.
The Acoustic Noise Cancelling switch is located on the front of the control module.
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. |
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:
NOTE: Tap Control is not a touch control feature. You must firmly double-tap the earbud in order to activate the feature.
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.
The operation switches are located in the control module battery compartment.
NOTE: Some operation switches are not available on all models.
FUNCTION | POSITION | DEFAULT | DESCRIPTION |

By default, the reversible microphone assembly ships from the factory attached to the left side of the headset, however, in some configurations it may ship separately. It can be easily attached to the left or right side of the headset.
To move the microphone assembly from the left side of the headset to the right side:
When the battery light blinks red, the batteries must be replaced.
NOTE: For aircraft-powered headsets, batteries are not required for operation if aircraft power is available. See "Aircraft Connectors".
Aircraft connectors are available in several standard aircraft connector options.
POWER TYPE | CONNECTOR OPTIONS |
Battery power only. | Dual plug (general aviation) |
Flex Power - Aircraft power or battery power. No battery needed when connected to aircraft power. NOTE: This version is often called Flex powered and comes with an Auto On function. | 5-pin XLR NOTES:
|
NOTE: Contact Bose customer service for more information about these connectors.
The battery (only) powered version of the headset has two general aviation aircraft connectors that insert into specific jacks on the aircraft control panel. The microphone connector is shorter, thinner and has a slightly different shape than the intercom connector.
Gently pull back on each connector to remove the connector from the aircraft control panel.
The 5-pin XLR, 6-pin Lemo, and 7-pin XLR aircraft connectors insert into the aircraft control panel and provide the headset with aircraft power and intercom audio.

New alkaline AA batteries supply up to 45 hours of power for the headset. Battery life varies with the ambient noise level of the aircraft, temperature, ear tip condition, Bluetooth use, and age of the batteries.
Bluetooth wireless technology lets you stream audio from mobile devices such as smartphones, tablets, and laptop computers. Before you can stream audio from a device, you must connect the device with your headset.
NOTE: This section applies to Bluetooth headsets only.
NOTES:
Download the Bose Connect app, and follow the on-screen connection instructions.
Once connected you hear a tone, and the Bluetooth light blinks blue.
The aircraft intercom system (ICS) is always the headset's primary audio source. When the headset is plugged in to the aircraft, intercom signals are always heard and cannot be muted by the headset. You can configure how you hear the device audio with the intercom.
NOTE: Bluetooth audio will never override the intercom.
The Bluetooth priority switch is located on the front of the control module.
FUNCTION | POSITION | DESCRIPTION |
Mute | ![]() | When an intercom signal is detected, Bluetooth audio is temporarily muted until intercom audio ceases. |
Mix | ![]() | When an intercom signal is detected, Bluetooth audio is mixed with intercom audio. You hear a maximum of two audio sources; the intercom plus 1 Bluetooth device. |

NOTES:
Press and hold the Bluetooth/Multi-function button for five seconds to turn the Bluetooth feature off.
Move the Bluetooth priority switch to the Off position.
Use the Bose Connect app to disconnect your mobile device.
TIP: You can also use Bluetooth settings to disconnect your device. Disabling the Bluetooth feature disconnects all other devices.
When powered on, the headset tries to reconnect with the two most recently-connected devices.
NOTE: The devices must be within range (30 ft. or 9 m) and powered on.
When your connected mobile device moves out of range, the connection is lost. The headset automatically attempts to reconnect. If the headset is unable to reconnect, it returns to pairing mode. After five minutes of inactivity, the Bluetooth feature turns off.
You can pair additional devices to your headset. These Bluetooth connections are controlled with the Bluetooth/Multi-function button . Before connecting an additional mobile device, make sure this feature is enabled.
TIP: You can also easily manage multiple connected devices using the Bose Connect app.
NOTE: This section applies to Bluetooth headsets only.
You can store up to eight paired devices in the headset pairing list, and your headset can be actively connected to two devices at a time.
To connect an additional device, use the Bluetooth menu on your device or download the Bose Connect app.
