This is the feature that the manufacturer forgot on the Bose Aviation X Headset. The adapter replaces the manufacturer's cover which is used to cover the 5-pin plug on the unused (non-microphone) earcup. If the microphone is mounted on the left earcup, the adapter goes on the right, and vice-versa.
This adapter plugs into the opposite side headphone from the mic and has a 3.5mm jack that is able to accept MP3, I-pod, and any other device that accepts a 3.5mm input.
1 year full warranty.
