Plugging 2.5mm monaural into 1/8" steeo. ????

[micky]

I didn't start working on this soon enough to buy the proper airplane
adapter for sound, like
http://www.amazon.com/AIRPLANE-HEADPHONES-ADAPTER-AIRLINE-EARPHONE/dp/B002Q3II30
or
http://radioshacklb.com/index.php?route=product/product&product_id=1345
charge 5500 LBP Lebanon Pounds!! Not enough time to ship from
Lebanon.

Office Depot used to have this but doesn't anymore.

But can't I just plug my 2.5 or 3.5 mm stereo plug in the monaural jack
and get sound in one ear? One ear is good enough for me

2.5 mm = 0.1"
3.5 mm = 7/5 x 0.1" =0.14" inches,
Maybe neither is close enough to 1/8" = 0.125".

I have a bunch of other adapters. And other earphones. What size
plugs into computers?

I fly rarely and the last time I think the earphones were just plastic
tubes.

Contrary to popular belief in the US, there's really no such
thing as a 1/8" jack. The common sizes are
- subminiature jack 2.5 mm,
- mini-jack 3.5 mm,
- phone jack 1/4" = 6.35 mm.

3.5 mm. Erroneously called 1/8" in some not-yet-metricated
countries, even though 1/8" would be 3.175 mm.

........ and propulsion was via propellers. :-)

I have not seen the "stethoscope" earphones since maybe the early 90's.

I'm pretty sure it was 10 or more years later than that. A lot of
airlines out there.

Believe you me, I've wondered about this, why there would be two sizes
so close together, and how come I never come across plugs that don't fit
jacks.

So since I have stereo headphones with a 2.5mm plug, and an adapter that
successfully converts that to 3.5 mm, one or the other plug should fit
without wobbling and I'll eitther get one channel in one ear or the same
channel in both ears, right? I think I've done that before without
involving an airplane.

So I'm in good shape!

Well, I'm not metricated myself. I'm probably anti-metrical, but if
that's how big it is, that's how big it is. It may be all European and
communist and all that to use metric, but it's worse to lie about the
size. So it should be called 3.5mm.

That Lebanese Radio Shack page unabashedly says 1/8". I thught they
used metric in Lebanon.

The Amazon page avoids using any dimensions, only says Airline and
Airplane, and has a bunch of competitors at the bottom of the page, but
the distance from one plug to the other is fixed. Might be better off
with the Lebanese one, which has two plugs on separate 2" cords

I ordered one from Monoprice last night, only 80 cents plus 2.25
shipping (and I added something else I needed to the order) but I forgot
that I'm leaving early Friday, not Friday night, so it probably won't
get to me in time.

Thanks.

Blimey, one of these days you North Americans are going to have to wake up
to the fact that the use of "Fractions of Inches" should have died last
century.

This is a classic case in point.
