Help with wiring colors on old headphones

Which color wires are the positive ones?
The colors in one of the leads are red & blue and in the other lead black &
yellow. (No wire is used as screening - there's just two wires in each
lead.)

The four wires are already grouped as two pairs, so we already know which
two wires go together.
I want to get the phasing right (even for headphones). I need to know
which color wire in each pair is the positive.
Are you familiar with decoding these red & blue and black & yellow
headphone wires?
Dave Plowman (News)
Black and blue are the commons. Not that it would make any difference if
you commoned red and yellow.
You can check for sure by unplugging the leads from each actual earpiece
(red and blue plugs), but be careful to pull on the actual plug only. The
pins are of slightly different sizes.
Hope you have a source of the muffs for these - they crumble to dust quite
quickly.

No you don't need to know it. It will be abundantly clear if you have
the phase in one ear wrong by 180 degrees - unless that is you are deaf.

I would hazard a guess red, yellow are positive and blue, black
negative. But why didn't you make a note of where the cables were
connected when you took the original apart?
There are only four wires as two trivially distinct pairs - the worst
that can happen is you need to flip a pair if you choose incorrectly.

Years ago someone wired up these headphones to a 1/4 inch plug and they
they say they don't know what polarity meant. There's no point following
their clueless wiring.
Out of phase headphone transducers create a far more subtle adverse
effect than that noticed in loudspeakers, so it is not something
immediately evident by A-B testing. Nor is testing necessary if someone
here knows what the color coding is.

You must know the headphones well because I had long forgotten the leads
plugged into the earpieces. I didn't realize the mini plugs were keyed to
go in only one way around. With that info I could have continuity tested
the colored leads to each of the larger pins on the plugs but you saved me
doing that becauase you have given me the color coding too. Thank you.
You're right about the muffs crumbling. I threw them out. First I'll see
what the cans sound like now and then decide if it's worth getting new
muffs.
It's been instructive to see how many people misunderstood what the
original question was trying to solve and they gave obviously useless, if
not misleading, advice. It's never been the same since Eternal September.

There is no phase cancellation like there is for speaker sounds because the
sound from each headphone transducer is interfereing with the other.
Your lack of knowledge is made all the more lamentable by the unwarranted
self-assurance with which you conduct yourself.

What more do you need? Phil's given you a test to see if the phasing is
correct, can you not figure it out, or what to do if the click seems to
come from your right or your left?

Actually that's untrue, nobody misunderstood the question or gave useless or
misleading advice. And Phil is quite right, the effect of having the
headphones out of phase with each other is not at all subtle, it is at least
as obvious as it would be with speakers. Just because there is no phase
cancellation in the air doesn't mean that the brain is not immediately aware
of the phase difference heard in the two ears.

Did anyone ever come up with muffs better than the OEM crap for these?
I have two or three bald pair at the back of the cabinet. I ordered
new muffs for one of these, once, at some amazing fraction of the cost
of a new set of headphones. (Hearing I had bought new muffs, a friend
pressed his on me. Frustrated, he had bought Koss headphones.)

Wrong, I'm afraid. I myself have heard a 2-channel sound clip on the net that
irrefutably demonstrated that interference does occur in the brain, at
lowish frequencies, but not that low. Up to a few hundred Hz.
It was a clip of (f Hz) in one channel/earphone, and (f+delta Hz) into
the other earphone.
With just either (one) earphone inserted, you could hear just a plain tone of
f or (f+delta) as expected.
With both in, you heard the beating at a few Hz, proving that addition/
mixing was taking place in the brain.
It sounded very weird, and I was very surprised. but the effect was utterly
obvious and undeniable.
I can't remember now where I found the sound sample, but IIRC it was a link
on Wikipedia.

Wire them up to a mono source and insert a dpdt switch so you can
easily and quickly reverse the phase of one earpiece. Insert a PVC
T coupling between the earpieces. Compare the sound levels coming
from the bottom of the T while flipping the switch. Loudest is in phase.

** If both ear phones work but are wired out of phase, the AA cell click
test produces a sound that seems to be originating outside the head on both
sides. Mono speech or music sounds much the same.
The effect is far MORE pronounced than with typical stereo speakers in a
room.

Headphone listening is nothing like listening to stereo speakers or natural
sounds in the environment - the outer ears are no longer involved and moving
one's head has no effect on the sound heard. The stereo effect becomes
extreme and the "sound stage" appears to be inside one's head extending left

I have Sennheiser HD414's from ~1980. In the last year the muffs have
gone from developing a lasting flat where they rest on a surface, to
literally crumbling.
Sennheiser's national distributor has replacements for $A9 plus
postage. I'm impressed.

My first guess would be blue+ red- and black+ yellow-, but here's how to
find out. First hook them up, arbitrarily starting with what I said, or
the other way - it's a coin toss. Listen to something in mono. You'll
have to find your own mono source. (finding a mono source is left as an
exercise for the student.)
If the resulting sound comes from the middle of your head, you got
it right. If it sounds like two sources on either side of your head,
you've got the polarity wrong on one side or the other.
I'm getting this from remembering (I think) that in the old 4-wire
phone lines, green was tip and red was ring, and black was tip and yellow
was ring.

No. Don't mess around with "PVC T-coupling" or any other such nonesense,
just put the headphones on and listen. The effect of having them
out-of-phase is immediate and obvious. And as Phil said that is s far more
reliable method of ensuring correct phasing than assuming that the lead
colour use is consistent.

** Must be lotsa folks who have never had the dubious pleasure of listening
to out-of-phase signals on stereo phones - cos moulded on plugs and three
wire leads makes doing it even deliberately a bit tricky.
But those who have owned or mucked about with * electrostatic * or *
electret * head phones might well be aware of how it sounds - as there are
four wires to deal with and every chance that at some stage miss-connection
to the amp's speaker terminals will create the issue.
Damn shame these products have all but disappeared or become extraordinarily
expensive.
As a reference for sound quality ( or to hear exactly what is on a

That's why we really should have binaural recordings for headphone

Any tips how? I once bought a Pelican case to hold something
disassembled, and I had a heck of a time cutting cavities in the foam
provided to fit the pieces. Cutting foam into cylinders would be hard
enough -- making them so they can slip over the earpieces seems
nightmarish to me.

It really does not matter how you do it of course as long as the

A pair of headphones with incorrect phasing is about as obvious as being
hit on the head with a brick. Amplifier to mono and try listening to
something. If you have it right the sound source will appear to be very
close to the middle of your head and if not it will be in different
places or spread out depending on the frequency.
If you can't tell the difference you don't deserve a hifi system.
You could always look at the cables at the transducer end.

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.

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.

** All you have to do is un-link the common ground - it leaves the two
transducers in series and out of phase.
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.

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.

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.

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.

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.

Actually, I first tried it more than 40 years ago.
This "lifted-common" wiring is the principle on which Dynaquad was based.
What passes through the speakers (or headphone drivers) is the difference
between the two channels. It doesn't take much intelligence to see that this

There are at least two Star Trek episodes in which Captain Kirk makes a
computer self-destruct by throwing illogic at it. How much longer will it
take for you to plotz by being told you're wrong? WRONG, WRONG, WRONG,
WRONG, WRONG.

What a bizarre thing to say, of course it doesn't "wipe-out" the mono
signal! Both transducers still have the mono signal flowing through them,
all that has happened is the diaphragms are out of phase with each other
(one going in whilst the other is going out), each ear will thus hear the
full mono signal. The only place that cancellation could now occur is in the
brain, and the human auditory system doesn't work that way.

It's never a good idea to write like that when *you* are the one in the
wrong.

If you disconnect the sleeve whilst feeding the same signal to both tip and
ring then yes, you are right, but that's not what was being suggested here.
What *was* being talked about was connecting a mono signal across tip and
ring, thus putting the two transducers in series.

That isn't the way I read it, but you're right -- with respect to that
configuration.

Pet, removing the common leaves just the difference signal. If the amps
are matched and being fed with mono there isn't one.

Consider each amp as a simple voltage supply with the negatives commoned.
Say 6 volts each or whatever. If both are exactly 6 volts no current will
flow between the positive terminals. Same with a mono signal.
I'm utterly surprised there's any argument - it's a classic way to look
for differences between two channels.

there will be zero audio, regardless of the relative phasing of the
headphones. The only way to test the phasing is to reverse one phone
completely (swap live and common).
