Their website says that in order to plug into audio during the flight you need a 3-prong adapter. Anyone know what specific adapter they are referring to?
The three prong jacks work a prong for the left and right audio channels and a third prong for the noise cancellation feed. With the two prong adapter you get the audio out to a regular headphone jack. Kinda like what UA uses with a two prong adapter in there seats where one jack is stereo sound and the other is for noise cancellation data.
