A pair of headphones with a sensor mechanism in the cup that detects the position of the ear of the wearer. If you put them on the "wrong way round", the sound is automatically cut off.
That's it.

I know that records get mastered so that they come out through one side of a stereo or t'other, but surely when you've got headphones on it doesn't really matter, it isn't as though you're going to miss some subtle nuance of the music, you've got it being played directly into your skull. |
|
| |
They should label left with an L and right with an R ;) |
|
| |
The problem arises when a movie with a stereo soundtrack is watched with "reversed" stereo ..... a sound may "track" left-to-right whereas the image may track right to left; or two performers amy be stage left and satge right, but their voices may be coming from the "wrong" side. |
|

[8th] Well then surely your television should just flip the image horizontally? |
|
| |
//the sound is automatically cut off// You don't think that automatically swapping the channels might be less irritating for the end user? |
|

//a sensor mechanism in the cup that detects the position

|
| |
And this sensor works how, exactly? (And, for that matter,
how exactly?) |
|
| |
It uses like, science 'n stuff, cmon. Let the eggheads figure out the details. |
|
| |
It uses a scanning infrared laser diode array and a photodiode receiver to generate a low resolution image of the pinna, which it then compares with a library of stored images and via averaging techniques decides which side is which. |
|
| |
Seriously, working out left and right is a non-trivial problem.
It's going to need a nose-detector. |
|
| |
I'd just mark 'em left and right and call it a day. |
|
| |
What about people who are born with backwards-facing ears?
I'd say this idea qualifies as discrimination against that
particular group. |
|
| |
... and therefore should be supported completely. |
|
| |
There has been some development of home audio head tracking systems which allow headphone soundfields to follow user head motions. See [link] for example. |

Should be simple to detect excess COv2 from the nose except in high winds. [link] |
|
| |
If you're concerned about sound/picture synch, the display could emit an inrared signal to either alert you to reversed headphones, or make the switch electronically. |

... and remember, men! Wear your Moriarty nose-detectors! |
|

Good idea [+]. Can it extend to other things like cutlery or shoes? When very, very drunk that would be handy. Though it might encorage walking which might not be a good idea. |

... but only if you're travelling by Leather Omnibus. |
