The three buttons on Apple's standard white iPhone earbuds can be pressed in combinations that pretty much eliminate the need to take the phone out of your pocket.
These controls are simple and easy to remember while still allowing for a wide range of control over your device.
You can even use them to ignore a phone call.
Fast forward by tapping the center button twice and holding down on the second tap. Rewind by tapping three times and holding down the third tap.
Switch to a new incoming call by tapping the center button once. You can end that new call by holding down the center button for two seconds.
