Its quite easy to miss the point of this app, a good pair of noise isolating earphones such as the etymotics can be deadly, headlines all over the world confirm this.
The point of this app is if you have enough of the outside world coming in through your earphones or headphones while you are listening to music, you'll hear a car approaching while its still some distance from you, in other words you remain aware of your surroundings.
There's also a microphone trigger function that switches the mic on when noise levels exceed a predetermined threshold (set by moving the red scale across) but this is more useful in the office or home where you don't want to hear any background noise but do want to hear a phone ringing.
Also, the app uses the microphone on the etymotic earphones so you can tuck your iPhone or iPod away in a pocket, it will only use the iPhone's built in mic if your headphones don't have a mic.
Are you convinced yet BDB?
