Airplane Headphone Adapter, UCEC 3.5mm Golden Plated Airline Earphone Adapter for In-flight Entertainment System, 2 Pack

I purchased this product for upcoming international flights. Our flights were from NY to Moscow and back using Russian Airlines (Aeroflot) on Boeing 777-300ER. Everything worked great even though on the way in it didn't work properly. But after testing the airline provided ear plugs it turned out the seat I was in had malfunctioning equipment where only one ear was working.On the way back no such problem.The quality of the product looks and feels great. As for the noise cancellation, it's hard to tell. It's not worse than airline provided ear plugs for sure.Totally worth the price for 2 pieces set! One of the best investments for a long trip - the ability to use your own comfortable headphones!Of course if the airline you are using doesn't have double plug, you don't need it.

Happy with this product

Inexpensive and exactly as described.

We travel regularly and use Bose noise cancelling headphones while on planes. These adapters allow the full sound experience available via plane systems. I've tried them in economy and business seats and the sound quality is as good as if you use the supplied hardware from the airline. The materials are good quality and reliable.

Bought to use on airline, but found they changed to single headphone jack. Guess this is pretty much useless to me now.
