3. Setup

3.1. Inserting the AAA Battery

The noise cancelling feature of your QuietComfort 25 headphones requires a single AAA battery for power. Locate the battery compartment on one of the earcups, typically by gently twisting or sliding a cover. Insert the AAA battery, ensuring correct polarity (+/-), then close the compartment securely.

Connect the smaller end of the 56-inch QC25 inline remote and microphone cable into the headphone jack located on the bottom of the left earcup. Connect the standard 3.5mm end of the cable into the headphone jack of your Apple device (e.g., iPhone, iPad, iPod) or any other compatible audio source.

4.1. Using the Inline Remote and Microphone

The inline remote and microphone cable allows for convenient control of your audio and calls on compatible Apple devices:

• Music Control: Press the center button once to play or pause music. Press twice to skip forward, and three times to skip backward.
• Volume Control: Use the '+' and '-' buttons to adjust the volume.
• Call Control: Press the center button once to answer or end a call. Press and hold to decline an incoming call.
• Voice Control: Press and hold the center button to activate voice control (e.g., Siri) on your Apple device.

4.2. Using the Airline Adapter

For in-flight entertainment systems that use dual-prong audio jacks, use the included airline adapter. Plug the 3.5mm end of your headphone cable into the adapter, then plug the adapter into the aircraft's audio output. This allows you to enjoy the noise cancelling feature and audio from the in-flight system.

5. Maintenance

5.1. Cleaning the Headphones

Regular cleaning helps maintain the condition and hygiene of your headphones:

• Use a soft, dry cloth to wipe the exterior surfaces of the earcups and headband.
• For ear cushions, gently wipe with a damp cloth and mild soap solution if necessary, then dry thoroughly. Avoid excessive moisture.
• Do not use abrasive cleaners, solvents, or chemical sprays.

To protect your headphones when not in use or during travel, always store them in the provided carrying case. The ear cups pivot to fold flat, allowing them to fit snugly within the case, preventing damage.
