Controlling your Samsung Galaxy device

The headphones have an in-line remote with an integrated microphone for con venient control of select devices.

Easily control volume, track selection, and voice applications, plus switch between music and calls.

Note: The S marking on the back of the remote indicates that these Bose^®QuietComfort^® 25 headphones are designed for use with Samsung Galaxy devices.

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.

If the headphones will be stored without use for more than 30 days, remove Alkaline batteries to avoid leakage.

Battery information
