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.
