5-pin phone plug?...

[Don Y]

Anyone know what sort of *consumer* kit would be using a 5-pin
(TRRRS) phone plug?

I\'ve got a cable that is terminated in a pair of three pin
(TRS) phone plugs on one end with what I am *guessing* is
a 5 pin phone *jack* on the other.

Sleeves of both plugs are tied together and the mechanicals of
the cable indicate the mating *jacks* will be located within a
few inches of each other. Insulators between sleeve/ring/tip
are color-coded -- red on one plug and green on the other.

I suspect this is something fairly common (but I\'m not big on
mainstream consumer kit).

I\'m not keen on casually discarding it as it may have some
possible future value to me (doesn\'t take much space to store!)

Hmmm... perhaps just a 4-pin jack (TRRS) and used for a headset
(mic+headphones)? That would agree with the color coding on
headphone and microphone jacks (for the male plugs) -- though
I would have thought the mic connector to just be two conductor
(and not three).

I\'ll have to see if I have a wired headset to test that theory...

Android phones and our dell optiplex\'s use the TRRS plugs.

I had a digital watch from 30 yrs ago (?)
with \"built in\" FM radio (Armitron?).
well, partially built in. All the analog stuff
and another dry cell was inside a \"blob of plastic\"
--that was inline & connecting the headphones to the watch.
The volume control was on this blob.
The connector to the watch was
a 3.5mm TRRRS. The tuning dial was on
the watch. So I guess some kind of extra
signalling was used for \"tuning.\"

Never saw another example of a TRRRS.

You didn\'t say what the diameter was. If 3.5mm then some gamers headsets
and controllers use them, no idea what the extra signals are. If 4.4mm
then some fancy hi-fi equipment uses them for balanced audio
(L+,L-R+,R-,Gnd). If 6.35mm then was used for some light aircraft radio
headsets.

What about stereo headphones and stereo mic? But the OP doesn\'t know it is a five pin jack. So this is all pure speculation.

I\'ve not found a wired headset so I can\'t experiment.

[I wasn\'t aware that the \"headphone jack\" on android phones
actually brought out the mic signal. I\'d only ever used headphones
with it! (something else that I will have to experiment with!)]

[[I also wasn\'t aware that the headphone (?) jack on optiplex\'s
also carried the mic signal (??) Each of my optiplex\'s has a
separate mic connector (redundant?)]]

But, that would make the most sense (as above). The cable
is undoubtedly used to allow a 4 conductor headset to be used on
a *PC* (the TRS plugs simply being selected \"as expected\"
for a PC and only 4 of the 6 possible conductors (I\'ve already
noted that the 3rd and 6th -- sleeves -- are wired together)
are actually used.

This is consistent with the color scheme used on the insulators
and the closeness that the mating jacks must be to each other.

I\'ll order TRRS & TRRRS plugs with my next parts order just to check
the (molded) jack to verify this; I\'d hate to carve up the jack
just to visually inspect it!

I\'ve seen TRRS used to bring the 4 conductors of a USB
connector into a 3.5mm jack -- which also doubled as
headphone output.

I\'ve also seen some overly *long* 3.5mm plugs (but can\'t
recall number of conductors).
