Opsætning
Indledende opladning
Before first use, fully charge your headphones. Connect the supplied USB charging cable to the USB charging port on the inline controller and to a standard USB power source. The charging time is approximately 3 hours. A full charge provides up to 20 hours of continuous use with Active Noise Cancellation enabled.
Tilslutning til en lydkilde
Insert the 3.5mm audio plug into the audio jack of your device (e.g., smartphone, tablet, laptop). The headphones operate in wired mode. If your device has separate microphone and headphone jacks, use the included headphone splitter.
Justering af pasform
Adjust the headband by sliding the earcups up or down until they comfortably fit over your ears. The semi-around-ear design is intended to cover part of the ear while providing good air permeability. Ensure a snug fit for optimal sound and noise cancellation performance.

Betjeningsvejledning
Aktiv støjafbrydelse (ANC)
To activate the Active Noise Cancellation feature, locate the ANC switch on the inline controller and slide it to the "ON" position. A blue indicator light will illuminate, confirming that ANC is active. This feature is most effective at reducing low-frequency ambient noise, such as engine hum or air conditioning sounds.
To deactivate ANC, slide the switch to the "OFF" position. The headphones can operate without battery power in common mode (ANC off).

Lydafspilning
Once connected to your audio source, audio will play through the headphones. Adjust the volume directly on your connected device. The headphones deliver rich bass and balanced sound for an immersive listening experience.
Opkaldsfunktioner
The inline controller features a built-in microphone and an answer/end call button. Press the button once to answer an incoming call or to end an active call.
Brug af flyadapteren
For in-flight entertainment systems, use the included airplane joint adapter. Plug the headphone's 3.5mm jack into the adapter, then insert the adapter into the dual audio jacks available on most aircraft seats.

Opretholdelse
- Rensning: Brug en blød, tør klud til at rengøre hovedtelefonerne. Brug ikke slibende rengøringsmidler eller opløsningsmidler.

- Batteripleje: To prolong battery life, avoid fully discharging the battery frequently. Recharge the headphones when the ANC indicator light signals low battery.
- Komfort: It is recommended to take off the headphones every 2 hours to allow your ears to relax and to ensure continued comfort during extended listening sessions.
