Works as designed but.... – Awareness!® For Etymotic Review

This app works as designed. In a noisy datacenter it cancels out unwanted noise. The only downside is that it is a battery vampire! Even if the app isn't running you will have to charge your phone daily. Active you will charge multiple times a day. If they can work out the battery issue I'd keep it installed.
