Have twin tablet DVD players with wireless (infra red) headphones for the boys. Anyway first time we used it in the eos, noticed both boys sitting very close to the screens, asked them to lean back, but then they complained they couldn't hear because of sound interference. Now I wonder if all the electric motors etc. for the roof has something to do with that. I'll try switching channels on the headphone, but failing that we'll have to go back to the normal headphones. Any ideas out there?
