Hay guys.
I'm seriously looking at installing a roof mount dvd player in the patrol for those long trips.
One question I have however is the wireless headphones.
I'm looking at something like this in a 9" screen

Now if one set of headphones go walking or break..... How hard would it be to replace them?
Could I grab any old ir set or would I need these expect units
