Everest Elite 700

This app works great with my 700 series. The only thing is the settings do not processed if I use the headphones with my iPad versus my iPhone. It keeps the settings from the device that youre connected to you and therefore from the app on that device. It works consistently every time from my iPhone and allows me to adjust the EQ and the ambient sound from the noise cancellation settings.
