I used the ER-20's for the first time today at the movies. I have used them at concerts and clubs before, but never at a theatre.
I went to go see V for Vandetta and one of the opening scenes with a character swishing knives through the air was incredibly ear piercing. I was very comfortable after inserting the ER-20s, and I noticed my friends in attendence with me had a hard time in the loud scenes.
I really cannot understand why movies are so loud? Is it my imagination or false sense of memory that makes me believe theatres today are louder than in the past?
I find it odd that there is so much protest about controlling volume levels for portable audio devices and yet movie theatres can get away with anything.
