Hello,

My son just bought a new pair of Bose Headphones, the "SoundTrue" model.

Their .pdf manual says the Plug is 3.5 mm and also 1/8 inch.
Obviously, it can't be both, as their is a "meaningful" diameter
difference (0.0057) beteen these two dimensions.

I used to remember that there was always a bit of a problem, as some
Plugs that mfg's used were 1/8 inch, and some were 3.0 mm (not 3.5 mm).

The reason I'm asking is that when he plugs it into our (old CRT style)
Panasonic TV audio output Plug, it wiggles a lot and does not make good
contact.

Can someone who is a lot more knowledgeable about these kinda plugs and
jacks perhaps straighten us out on all of this. (are there adapters ?)

Also, the Plug seems to have 4 electrical sections.
Have never seen one with more than 3.
What are (each) of them for, please ? Diagram anywhere ?

Would be most appreciative for your help.

Thank you very much,
Bob

Actually they can, since they simply rely on the socket spring contacts
bending in or out a little. They are definitely NOT precision connectors.

A pretty common problem, especially when the sockets have had a fair bit of
use.

They have been used in video camera's for *many* years, and headsets that
have both stereo audio and microphone connections.

That would depend on the actual device. Apple for a start use different
connections than most others. I have no idea what Bose have done in this
case, but the info should be available somewhere.

It appears to be this model:

http://www.bose.com/controller?
url=/shop_online/headphones/ae_and_oe_headphones/soundtrue_headphones/index.jsp
&Variant=soundtrue_ae_headphones

It appears to have the ability to add a microphone or it may come with one
built in somewhere. The FAQ tab says it will work with Apple products. So, I
believe it has a 4 conductor TRRS plug so it can carry the mic and stereo
headphone signals. It appears it has a CTIA TRRS plug that works with Apple
and Nokia, among others.

This Wikipedia article outlines the TRRS standard for the 4 condutor plug you
describe.

http://en.wikipedia.org/wiki/Phone_c...TRRS_standards

It may not be designed to work well with a standard 3 conductor plug like your
CRT set has. Perhaps an adaptor will help. For example:

5mm-trs-adapter.html

I'm thinking the problem is you have a fairly worn jack in your old crt tv. They fail fairly commonly. I've had to replace a few in ipods and such.

1/8 inch is American and 3.5mm is Rest Of The World.

It should actually be the same plug, just that Americans don't do mm.

The original dimensions of plugs were 1/8" aand 1/4" . They are now
described as 3.5mm and 6.3mm .

0.0057 is within the range of manufacturing tolerance, simple wear and
tear, or maybe even room-temperature variation. I wouldn't stress over it...

Right, especially depending on where in the world you live.

And more particularly well within the range of the spring contacts!!!
These are NOT precision connectors.

Me either.
