From the article:
When we went to our seats, the wait staff let us know that despite the fact that the previews were playing, we wouldn’t know until the movie actually started whether we could see the film or not. If it didn’t work, the screen would just turn black. Luckily, the film went through without a hitch.
My wf-xm4 earphones have battery problems and sony won’t do any about it. it’s a known problem, so I went out and got a sony es receiver, that has a known hissing problem and they won’t do anything about it. Maybe ill learn someday.
