Earpiece in Captain America: The First Avenger

Captain America is known as one of the best Marvel movies, and it created an amazing storyline that Chris Evans would follow throughout the entire franchise. This movie focused heavily on its attention to detail and attempts at realism despite it’s fantastical plot, but there was a serious slip-up in one scene. About an hour and a half into the film, you can clearly see this soldier wearing a state-of-the-art earpiece. There’s no way technology like this would have been used during World War II, which is when this scene is supposed to take place. It’s only a minor detail, but it can definitely pull you out of the scene if you notice it.
