That is very strange. In all my recent flight they have been quick to tell people that they cannot use headphones during takeoff. I always thought this was so you could hear security announcements. The document regulating this is:

And it says for example about Portable Electronic Devices:

Prohibiting the operation of any PEDs during the takeoff and landing phases of flight. It must be recognized that the potential for personal injury to passengers is a paramount consideration, as well as is the possibility of missing significant safety announcements during important phases of flight. This prohibition is in addition to lessening the possible interference that may arise during sterile cockpit operations (below 10,000 feet).

The FAA regulation that covers this topic is Advisory Circular 91.21-1B. Agency spokesman Les Dorr says that “while an Advisory Circular is not mandatory, in practice all airlines and other operators adhere to its provisions. Airlines generally consider the ‘prohibited’ period to begin when the cabin door closes for pushback.” One big reason is lawyers. The FAA’s regulation makes the airlines responsible for governing the use of portable electronic devices on their airplanes, ensuring that carriers err on the side of non-litigious caution.
