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
It appears to be this model:

&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.

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:
