Our Ford Territory has the Alpine PKG-RSE2 DVD Entertainment system. The SSL SHP32 Dual Channel headset works well with this system. They look and behave simular to the Alpine head sets which came with the car, setup is just add batteries, they turn off if no infrared audio signal is pickup after a short period of time, the sound quality is good and they are a lot cheaper that the Alpine head sets. The SSL SHP32 are adjustable so they fit children, small and large (58 hat size) adult heads.
