Nowadays, many people have Bluetooth speakers, and some of them may wonder if it is safe to take the speaker on a plane.
The Federal Aviation Administration (FAA) has not released any specific regulations regarding Bluetooth speakers in airplanes. However, the FAA does prohibit any type of portable electronic device (PED) that emits radio frequencies from being used during takeoff and landing.
So, technically speaking, you are not supposed to use your Bluetooth speaker during takeoff or landing. But once the airplane reaches cruising altitude, you are free to use your PEDs, including your Bluetooth speaker.
There have been no reported incidents of Bluetooth speakers interfering with airplane navigation or communication systems. So as long as you follow the FAA's guidelines and don't use your speaker during takeoff or landing, you should be fine.
