Ugreen's "Bluetooth 5.0 USB Adapter (Transmitter & Receiver)", with product number 80889, is designed to work with Bluetooth-enabled devices, but is not specifically suitable for use in aircraft with headphones.

- Compatibility: The adapter is compatible with computers and Bluetooth peripherals such as keyboards, mice, speakers and headphones, but does not work directly with games consoles or other devices without a USB interface.
- Aeroplane use: Airplanes often have specific rules regarding the use of electronic devices, and Bluetooth headsets may be subject to restrictions during certain phases of the flight. However, the adapter itself should have no technical problems operating in an aircraft if the aircraft rules allow it.

In summary, although the adapter may technically work, it is important to check the aircraft's rules on the use of electronic devices before using it.
