Wearing and adjusting your product | Bose A20 Aviation Headset
Here are some guidelines to fit your headset.
Proper fit on your head is important both for comfort and optimal noise-reduction performance.
Wearing the headset
- Use the L (left) and R (right markings above the earcups to orient the headset properly
- As you put the headset on, adjust the earcups so the cushions complete surround your ears
- Adjust the headband so it rests gently on top of your head
- A low, rumbling sound or frequent, brief losses of noise reduction may indicate an improper fit or blocked earbud ports
- During a long flight, you may feel a slight pressure point, which can be relieved by adjusting the headband position. As you use the headset, you'll develop a sense of how it should sound and feel, which can help while adjusting it
- Make your final adjustments with the headset powered on in a noisy environment. In very loud conditions, such as during takeoff, you may experience a brief reduction in noise cancelation as the headset compensates for a momentary pressure change.
Microphone placement
Microphone placement is important for clear communication. With the headset on your head, make these adjustments:- Move the microphone boom until the microphone is level with your mouth
- Face the talk side of the microphone toward your lips
- Position the microphone 1/2" (1.5 cm) from your lips and slight off-center. Avoid contact with the microphone and your lips
- Try on the headset and test its operation before flight.
