BATTERY/CHARGING INFORMATION
How do I charge the QC
®
20 and
20i Acoustic Noise Cancelling
®
headphones? How long will they
take to charge?
These headphones can be charged using the USB cable supplied in the
box. Plug the micro-USB end of the cable into the connector on the
control module. The USB end of the cable can be plugged directly into a
computer, or it can be plugged into a USB wall charger to allow charging
from an electrical outlet (like the charger that comes with the Apple
iPhone). Allow up to two hours for the headset to fully charge. While
charging, the power status indicator will flash amber. Once fully charged,
the power status indicator light will turn solid green.
What is the typical battery life per
charge?
The battery will provide up to 16 hours of use per charge.
How do I know how many hours of
battery life are remaining?
The power status indicator light on the control box will be solid green until
there is approximately 3 hours of battery life remaining. At that point, the
light will begin flashing green. When the light goes off, battery power has
been fully depleted.
Can the battery in the QC
®
20 and 20i
Acoustic Noise Cancelling
®
headphones
be replaced?
No. The battery in the QC
®
20 and 20i headphones cannot be replaced.
STAYHEAR
®
+ TIPS
How are the StayHear
®
+ tips included
with the QC
®
20 and 20i Acoustic Noise
Cancelling
®
headphones different from
the original Bose
®
StayHear tip?
The StayHear
®
+ tip is made of the same soft silicone material as the
original StayHear tip, but it utilizes a unique umbrella shape to create a
gentle seal at the entrance of the ear canal. This seal is the basis for both
the total noise reduction and audio performance achieved by the
QC
®
20 and 20i headphones.
Why are there three pairs of ear tips?
Three different sizes of StayHear
®
+ tips are included so you can select the
size most appropriate and most comfortable for you. You will have to
experiment to find the best fit for your ears and may find that having a
different size for each ear is most comfortable. Typically, most adults will
prefer the medium-size tips.
