-Despite being labeled officially as **'a headphone jack'** there are strong indications that it is not a good idea to use it as an headphone jack. __It is presumed to damage the device__. - Advised is to use it as an 'line out' instead. And to use an amplifier for headphones between it.+Although a stereo audio jack may physically accept a 3.5 mm headphone plug, using it this way is not recommended and **may potentially damage the device**.
