Setup
Initial Charging
Before first use, fully charge the headphones.
- Connect the small end of the provided USB charging cable to the USB Charging Port on the headphone's inline controller.
- Connect the larger end of the USB cable to a powered USB port (e.g., computer, USB wall adapter).
- The Noise Cancelling Indicator Light will illuminate during charging.
- Charging typically takes approximately 2 hours for a full charge. The indicator light may change or turn off when fully charged.
Connecting to Audio Source
- Insert the 3.5mm Audio Plug into the audio jack of your device (smartphone, tablet, computer, MP3 player, etc.).
- The headphones are wired and do not require Bluetooth pairing for audio playback.
Operating Instructions
Active Noise Cancellation (ANC)
To activate the Active Noise Cancellation feature:
- Locate the "Noise Cancelling On/Off" switch on the inline controller.
- Slide the switch to the "ON" position.
- The Noise Cancelling Indicator Light will illuminate, indicating ANC is active.
- To deactivate ANC, slide the switch to the "OFF" position.
Note: ANC primarily reduces low-frequency ambient noise. It may not completely eliminate human voices or sudden high-frequency sounds. The ANC function requires battery power. If the battery is depleted, the headphones can still be used for audio playback without ANC.

- Answering/Ending Calls: Press the "Answer/End Call" button once to answer an incoming call. Press it again to end an active call.
- Music Playback Control: This model primarily focuses on ANC and basic call functions. For music control (play/pause, track skip), use your connected device.
Using the Airplane Adapter
For in-flight entertainment systems that use a dual-pin audio jack:
- Connect the 3.5mm Audio Plug of your headphones into the single input of the Airplane Adapter.
- Insert the dual pins of the Airplane Adapter into the corresponding jacks on the airplane's armrest.
Maintenance
- Cleaning: Use a soft, dry cloth to clean the headphones. Do not use liquid cleaners or solvents.

- Water Resistance: These headphones are not water-resistant. Avoid contact with liquids.
