IMPORTANT: DO NOT STORE A BATTERY IN THE CHARGER.
• After charging, unplug the battery charger and remove the battery.
• Storing a battery in the charger diminishes the charged state of the bat-
tery over time and may permanently reduce the capacity of the battery.
Battery handling and precautions
• The battery does not have to be completely discharged in order to charge it.
You can charge the battery at any time.
• Never leave the battery in a discharged state. Charge after use and before storage.
• Avoid extreme temperatures when charging the battery. Battery charging should
occur within the temperature range of 32°F (0°C) to 95°F (35°C).
• A fully charged battery provides approximately 25 hours of use. Replace the battery
when it no longer provides adequate power after charging. To order a replacement
battery, see “Troubleshooting” on page 12.
• Keep the terminals on the battery, in the charger, and in the right earcup of the
headphones clean at all times. Dirty terminals may cause poor electrical connec-
tions and affect performance. For cleaning instructions, see “Cleaning” on page 12.

Using Your Headphones
Connecting to portable and home audio devices
The 3.5 mm plug on the headphones cord allows you to connect
your headphones to a variety of audio devices that use a 3.5 mm
output jack:
• CD, DVD, or MP3/digital audio player
• Desktop or laptop personal computer
Connecting to airline audio systems
The audio output connections on airline audio systems vary,
but they typically have dual or single 3.5 mm output jacks.
Note: Airline audio may not equal the high-quality audio you
experience from a home stereo or portable source.
Connecting to dual output jacks
Plug the headphone cord into the dual-plug
adapter and insert it into the dual output
jacks.
Dual 3.5 mm
plugs
Headphones
cord jack
Connecting to a single output jack
Pivot the movable plug so that it snaps in
place against the adapter body. Plug the
headphone cord into the adapter and insert
it into the single output jack.
Single 3.5
mm plug
Headphones
cord jack
Movable
plug
The dual-plug adapter lowers the volume
levels of strong audio output signals that
are common on airline systems.
If you find that the volume level is too low, remove the adapter and plug the
headphone cord directly into the 3.5 mm output jack.
WARNING: Use only the Bose® airline adapter to connect headphone to
airplane seat jacks. DO NOT use adapters intended for mobile phones as
this could result in personal injury such as burns or property damage due to
overheating. Remove and disconnect immediately if you experience warming
sensation or loss of audio.
