Awesome. Have fun. Try not to get overwhelmed. Just stay focused on what you really want to hear and be happy with it when you are done because there is no possible way to hear everything.
This was helpful, thanks. I was stressing a bit, but there just won't be time for everything. It's probably hard to learn anything conclusive from a quick audition in a setting like Canjam anyway(I've only been to one other, much smaller headphone convention), especially when you consider how our opinions on gear can shift a bit over time. So I'm just going to fugeddaboudit and have fun! Also, I should probably find something my girlfriend likes to do while we are there, since she's being such a good sport about it(and she bought the Canjam tickets anyway).
It's almost go time, ladies and gentleman
