Càrrega inicial
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.
Connexió a una font d'àudio
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.
Ajust d'ajust
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.

Instruccions de funcionament
Cancel·lació activa de soroll (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).
