Great Product - Must have App

I often work or read in coffee shops, live in an apartment near a freeway, and deal with unwanted noise in many ways. The app uses noise canceling techniques and adds a broad range of rain, harmonics, ocean, forest sounds to add additional masking. It responds to the level of local sounds and adjusts accordingly. It is great with standard ear buds but fantastic with noise canceling head phones. I can easily close the curtain and move into my own private and quieter world.
