United Airlines provides complimentary earphones on most international long-haul flights where seatback entertainment is available. In 2025, United significantly upgraded its audio experience by introducing Meridian headphones for its Polaris Business Class and Premium Plus cabins. For passengers in the Economy (United Economy) cabin on international routes, basic earbuds are typically offered for free to ensure everyone can enjoy the movies and music provided. However, on domestic U.S. flights, United generally does not provide free earphones in Economy. While some newer aircraft feature Bluetooth connectivity for your own wireless headphones, it is a standard "bring your own" policy for domestic routes. If you forget yours on a domestic flight, you may be able to purchase a basic pair from the flight attendants, but it is always best to pack your own 3.5mm wired set or a Bluetooth adapter to avoid the extra cost and ensure better sound quality.
