Connecting to in-flight entertainment systems

Audio jack configurations on airplanes vary. For a single 3.5 mm jack, first use the audio cable plug directly; for a dual output jack, use the included adapter.
If the airplane’s sound system is too loud for comfortable listening, the adapter can be used to reduce the volume with either a single or dual output jack.

Storing the headphones

Rotate both earcups so they lie flat. Then fold the right earcup in toward the headband. Place the headphones into the case.
Caution: If the headphones will be stored without use for more than 30 days, remove Alkaline batteries to avoid leakage.

Battery information

Compatible battery types| Battery life| Time remaining when indicator flashes
---|---|---
Alkaline| 35 hrs| 7 hrs
Rechargeable NiMH – Low self discharge| 28 hrs| 4 hrs

Note: While the indicator flashes, the headphones will continue to operate normally until the battery is fully depleted. Then the headphones will emit a soft clicking noise for approximately one minute before shutting down.
