A Dutch firm has come up with a GPS system that uses music to guide its users. This special phone application can be used to navigate aurally and if the sound seemed to come through the right earphone, this is where the system is attempting to guide the user. Should the sound come from the left, this is the direction intended. However safety may be an issue that the designer has not considered as wearing earphones while cycling, motorcycling or driving a car, bus or truck is not recommended.
