One ES100 feature that intrigues me is the equalizer in the app. I'm getting tired of using dedicated EQ apps for iOS, which have limited media sources, and operational issues. My questions: Is the equalizer implemented in the ES100 hardware, or just in the app? In other words, does it act as a *global* (all apps) equalizer for all phone output through the ES100? Does the app need to be active for the EQ to work, or is it just configuring it on the ES100? Is built-in EQ something we are expecting from the BTR3 and/or BTR5?
