Awesome app – Awareness!® For Etymotic Review

I love the app but am not an audiophile by any stretch. Would like to see more helpful explanations of the features. I haven't had this (or my Hf2 headphones ) very long so I have absolutely no idea what 'ducking' means. However, I will stress that it does exactly as advertised and then some!!
