Yes, you can use your earbuds, but it’s always a good idea to check if you can use them on a particular flight with the airline first. If you’re listening to music over the internet, you may be restricted to local music unless you connect to the in-flight wi-fi connection. You may also be restricted when using any wireless connection, including Bluetooth®, during take-off and landing and may be asked to turn off your Jaybird X4 earbuds until you reach cruising altitude.
