To replace the ear cushions, gently pull the old cushions off the earcup. Align the new cushions with the earcup and press them into place until you hear them snap securely.
Ensure the batteries are inserted correctly and are not depleted. Replace with new AAA batteries if necessary and check for any corrosion in the battery compartment.
Use a soft, dry cloth to gently wipe the exterior surfaces. For more stubborn dirt, a slightly damp cloth can be used. Avoid using any solvents or abrasive cleaners.
Check if the audio cable is securely connected to both the headphones and the audio source. Also, ensure that the source device is not muted and the volume is turned up.
When the headphones are powered on, you should notice a significant reduction in ambient noise. If not, ensure the batteries are charged and inserted correctly.
Yes, the headphones can be used passively without the noise cancellation feature, although the sound quality may be affected.
Store the headphones in the provided carrying case to protect them from dust and physical damage. Remove the batteries if the headphones will not be used for an extended period.
Use the dual-plug adapter included with your headphones to connect to the airplane's entertainment system. Insert the adapter into the headphone jack and connect your headphone cable to the adapter.
Check that the audio cable is fully inserted into the headphones and the device. Try a different audio cable if available, as the issue may be with the cable itself.
