Universal Earphones Proximity

A Japanese research team has come up with a set of prototype headphones that detect which ear they've been inserted in, then changing the channel accordingly, so users don't have to check first.

The one thing we all do before putting on a pair of headphones is check we’re putting the correct ‘bud in the correct ear, either with the little L and R markings, or by using another visual clue such as an in-line microphone to check which is which, thus ensuring the stereo separation is heard as the artist and audio mixer intended.

It’s a tried-and-tested but decidedly low-tech solution, however a Japanese team of researchers at the Igarashi Design Interface Project have come up with an far more high-tech alternative.

They call them Universal Earphones, and there’s a proximity sensor fixed to each earbud that knows which ear it has been inserted in, then adjusts the channel accordingly. With a 30mm detection zone in which to find either your ear or clear air, they work in a similar way to your phone’s proximity sensor.

That’s not all either, as another sensor is used to see whether both earbuds are being used by the same person, and if not, both the ‘buds get a mono signal. Why? So you don’t get just one side of a stereo track when you’re sharing a pair of earphones with another person.

Future plans for the Universal Earphones include a feature where the ‘buds know they’ve been removed from your ears, and pausing the music until they’re re-inserted, or even playing one track through the right earphone and another through the left.

At this stage, the Universal Earphones are in still in development and according to the BBC, there are no firm plans to mass produce them. However, the promo video reveals they would cost less than $1 per pair to manufacture, which could see them being snapped up in the future.

Of course, if you’re the sort of person who doesn’t check to make sure your headphones are in the correct ear, this won’t be of any interest. Just a quick question though, how can you be so blasé?

  1. Lephys at 2:58pm 7th February 2012 The existence of such technology is interesting from a "can we make something that does this and possibly use it for other things?" standpoint, but, really, just how difficult is it to take the 1 second it takes to look at one of your earbuds and know which one it is? There are only two. It's not as if you have to say, "Oh, that one's R. Alright... now lemme just check the other one. Oh, the other one is, indeed, the L one, and not some third, strange new earbud. Good, u_u"Seriously, how much would these earbuds cost? $100 just for a decent pair? "I'm sure glad I don't need to look at my earbuds anymore. I can now simply FEEL around for them and insert them into my cranium, 8D! Totally worth the extra money!"
    1. Andy Boxall at 12:52am 8th February 2012 It's a fair point, but they could make sense in certain situations - putting headphones on in a darkened room, or for anyone with poor eyesight who can't make out the often ridiculously small L and R markings.
      1. Lephys at 1:04am 8th February 2012 I suppooooose... it just feels a little like an infomercial, I guess, heh. "Tired of NEVER being able to put your earbuds in properly? Always having to LOOK at them before placing the correct one into the correct ear? Well worry no more!"I'll admit the technology has potential. I just don't really think it's at the top of the "this'll help solve some pretty potent problems" list of things we could develop right now. *shrug*
        1. Andy Boxall at 3:44am 8th February 2012 Ha! You do realize that those are the *exact* words they're going to use in all the advertising now, don't you?
          1. Lephys at 1:40am 10th February 2012 Hells yeah I do! *Files for a trademark AND a copyright, just in case*
