Help with wiring colors on old headphones

So?

You obviously don't know these particular headphones. I do.

You have little idea about the variations between humans. To know this, you have to be one yourself.

Hello Patrick.

Left ear: Yellow is + and Black is - Right ear: Red is + and Blue is -

Kindest regards.

I wonder if they will last any longer than the originals. At 6.66 UKP periodic replacement could get expensive, and stockpiling them would be useless.

A Google search for 414 headphones pops bhphotovideo up to the top, where the earpads are $5.50, about half the UK price.

Provide one believable and undeniable strand of evidence that you repair electronics for a living. Having a hyper-antisocial personality like yours would get you fired from any employer. And working for yourself, the same personality disorder would send prospective customers running for their lives never to return.

So unless you have some proof, I say you are a liar.

Start with a piece of open-cell foam about 1/2" thick.

In a piece of 1/8" thick stiff material (I used Masonite), cut a round hole a bit smaller than the diameter of the headset drivers (this will allow the foam to stretch slightly when you install the pads, so it'll stay in place).

Put the masonite on the foam and press it down hard (use clamps). The foam will bulge up in the hole.

With a very sharp small-bladed utility knife, cut around the hole to free the foam so it stands up in a straight-sided cylinder. Be careful not to cut all the way through. Then slide the blade across the hole while using a sawing motion. This will cut off the middle part of the foam.

Now, you should have a piece of 1/2" thick foam with a circular part in the middle which is 1/8" thick. Trim the outside to a circular shape, a bit larger than the drivers.

Of course, you can use a different thickness of masonite to control the thickness of the foam where the sound comes through, if you like a "softer" fit on your ears.

Now I understand your special problem. YMMD

Become unplugged. Best pull the usenet-plug. THX

With headphones and a correctly-phased mono signal, the sound 'image' is indeed slap-bang in the middle of your head. However, I find that mono signals sound dead compared with stereo, and when listening for a long time, this centre-of-the-head sound can start to become very tiring.

I find that reversing the phase of one of the headphones produces a much wider audio image, and is generally much easier to listen to. I can only hope that the purists will forgive me.

Heaps of schems have been published to turn mono into a phoney stereo using phase shift across the audio band - so one of them is worth a try too.

BTW:

A voice speaking to you from inside your head is a tad alarming for anyone with schizoid tendencies.

On this topic did anyone else see the NHK broadcast a few months back about a digital version of binaural recording that alters the phase frequency response of the high end of close miked material to extend the stereo sound stage vertically. The trick works by tweaking the frequency phase relationship to match what the ear expects from a wave incident at a given angle. It just sounded odd on loudspeakers.

The demo was of church bells meant to sound high up but I didn't get to hear it on headphones so I wonder if anyone else did. My Japanese isn't that good so I might be slightly misrepresenting what was said. It was a gee-whiz science programme so the explanation wasn't very detailed.

Yes, that's the easiest way to do it.

I suppose it's also the best test to do when checking that you actually have got the phasing correct. Just dab the common connection on and off. The difference will be very obvious, and instant.

Please remove your headphones immediately.

Not new, IIRC. I remember hearing a binaural recording of a man being shaved and having a haircut. Could just about feel the comb on the head.

What was new was that they could take close miked material and use digital processing to move it around the binaural sound stage at will.

The old way involved microphones inside a headlike dummy with ears.

Right.

Seems to have gone out of fashion. R4 used to have the odd play recorded dummy head - but not recently.

The late J Gordon Holt described the effect (for him) as cleaning out everything inside his end.

How bothered you are by it depends on how sensitive you are to "phasiness".

There is nothing wrong with listening to mono with reverse polarity. But if you listen to stereo that way -- you will, indeed, have the purists down on you.

If the signal is mono, you'll have pretty much nothing left to listen to. If it's stereo, the mono components will be cancelled, the L- and R-only components retained, with components in-between subjected to varying degrees of attenuation.

And, yes, Phil, whether or not you like it, what I've just said is 100% correct.
