Travelmall Airplane Pro Headphone-Jack Bluetooth Adapter with Foldable Dual Prong Jack


Airlines allow passengers to bring their own headphones on board to enjoy the in-flight entertainment systems. However, the audio output ports of the in-flight entertainment systems are typically equipped with dual-output 3.5mm jacks located on the arm of the seat or the seat back in front. Personal wired headphones usually have a single plug (3.5mm), and wireless headphones you bring may not be compatible with the plane's entertainment system due to the lack of Bluetooth functionality.

To address these issues, this smart 2-in-1 Pro Headphone-Jack Bluetooth Adapter is specifically designed to provide a solution. It offers great flexibility by allowing you to connect your wired headphones or Bluetooth headphones to the in-flight entertainment system, whether it has dual-output or single-output 3.5mm jacks.

In Bluetooth mode, it functions as a wireless transmitter for audio transmission, while in wired mode, it can be used as an adaptor to convert the dual-prong jack into a 3.5mm audio cable outlet, enabling you to connect your wired headphones. This must-have accessory is perfect for long flights!
