Smart Key icon Smart Key is a very interesting application from Sony that allows users to make changes to the way headsets are used.

Sony is one of the few companies that provide users with the ability to change the way headsets are personalized. You might not be aware, but even the most basic hands-free headsets can be personalized.

With the help of the Smart Key app, users can Configure the call key button when taking a call, listening to music or on the go launching the FM Radio. This works especially well for Sony headsets.

Some of the supported behaviors include Music control, Play/Pause, Next/Previous Track, Volume up/down, Voice command, Call handling, Answer/end/reject call, Volume up/down, and quite a few others.
