Most Ford Expedition DVD players use wireless headphones for the sound from the DVD player. They are usually stored in the seat back pouches in the driver and passenger seats. If you don't have the headphones you will have to get them from the manufacturer of the DVD player. Hope this helps.
if it fits into the audio socket, yes
That's the most common way to use them.The driver and front seat passenger don't really want to listen to a movie or game so it's best if the dvd player is attached to headphones.
The headphones are only for music, not to read the book to you.
They can,but it's not necessary.Since the front passenger and driver can't use the dvd player they will want to hear the stereo.Therefore the dvd player usually uses headphones.
The battery life on a sony portable DVD player really all depends on the size of it. It also depends on how you use the player. But average hours of a battery for a DVD player that is fully charged would be between eight and twelve hours.
you can use almost about every kind but the ones that work best are sony or phillips
you can use dvd's and a DVD ripper/converter called wondershare.
Sony is a great brand to use and lasts years.
