This replacement adapter lets you connect your QuietComfort headphones to in-flight entertainment systems equipped with dual-output or single-output 3.5-mm jacks. Simply plug the headphones’ cable into the adapter and insert it into the airline jack. Then enjoy powerful, balanced sound for music or movies.
In most cases, the adapter may not be needed as the audio cable included with your QuietComfort headphones can be used to plug directly into the 3.5-mm jack found on the arm of the seat or the seat back in front of you for in-flight entertainment.
