Traditional wired headphones
Wired headphones and earphones are allowed on flights and can be packed in either hand luggage or checked luggage.
They may need to be screened separately at airport security. During periods of heightened security, some routes may restrict larger electronic items in hand luggage, so always check current airline and airport guidance.
Bluetooth or wireless headphones
Wireless headphones are allowed on most airlines, but usage rules vary.
Many airlines allow Bluetooth headphones during most of the flight but require them to be switched off during taxi, take-off and landing. Some airlines allow them at all times, while others may ask for all electronic devices to be switched off on certain routes.
You may also need to manually switch Bluetooth back on after activating airplane mode, as airplane mode often disables Bluetooth by default.
