W221 S350 Rear aentertainment

[S350L]

Hi Guys

I have a w221 with rear entertainment and front split screen, but only 2 headphones. 1 with the split-screen logo on it and another with a left right switch.
Has my car has split screen in the front and two screens in the rear, so should I actually have had 3 headphones rather than 2 as only 1 pair works with the rear screens

Many thanks in advance

Thats a good question I have split screen on my CL but it's beyond me how the passenger gets sound as I have no headphones in the car and I can't see any plugs
