It is the smaller jack, like you'd find on a cellular phone.
It is my understanding that the audio socket for the 790 is the same as that used for the 780. Can you tell me if that is so? If yes, all I need do is get a cell phone ear bud to get a plug that fits? To me, the socket looks like a mini-plug with a tiny piece of copper placed in it to stop insertion of a standard headset plug. Could the 790 socket be described this way?

No!! Not true! I have been doing some searching for a earbud/headphone set for my MP780, I did conclude there are a few things to beware of.
I have about 6 or 7 types of headphones, I wouldn't worry about shorting out your audio jack as it really isn't high powered enough to get damaged from my experience, but I STRONGLY RECOMMEND you use something else to TEST them before you use them on your MP, because you could damage the device and/or your audio chip!! IF you do some modifications to your headphones - DO IT AT YOUR OWN RISK!
Having said that, here is my list of audio accessories:
1
) This one you have to be careful of, if you look at the jack closely, you will see a small problem on it. This isn't apparent, until you plug in the jack and find your audio recording application starts up automatically! I acquired these from someone else
(a friend
) as spares. The other problem, being stereo, one of the ear buds do not work!
2
) I found this, while rooting around in my fathers "Cable drawers", this was what my father once used with his Motorola T260
(Ironically, I had a T250!
), plugged it in, no hassle from day one, except a missing ear pad and a missing ear clip!
3
) Another spare headset, I found this within my collection, it came with my mothers phone, but guess what? It doesn't work with the MP at all! Works fantastically with my Nokia 3650 though, if you do not move the cable!
4
) I found these today, great things, just happened to be rooting around my friends drawer, opened up a mobile box, there they were, still in their sealed packet, not even used, asked to plug 'em in, and worked. Even better, unlike the previous ones, these did not activate the recording app, and stereo sound worked with no hassle.
5
) These are cheap 99p earphones, because they are so cheap and nasty, I decided to try something out, I cut off the end
(because they had a 3.5mm plug on them
), , unsoldered an end of a double ended 2.5mm mono plug, soldered both channels together, plugged 'em in, nothing 'appened! So, I moved the jack until I heard something, only one channel works! Worse, the jack has to be half way out, before you hear anything! So long for that idea!
6
) Acquired from Tescos in Chichester for £4.99, except they haven't been used, why? Look at item 1. These are listed to work with Samsung mobile phones, but I'd check the plug if I were you.
Looking for a good pair of ear phones or headphones:
Looking at my list, it seems like you are limited, well not really! You just need to look for a few things, firstly, do not go for one with a metal shord at one end of the plug, if you look at the MP jack closely, this is wat ACTULLY activates the recording application when you plug them in, as far as I can tell, there is no way to turn it off!
Look for one with a stereo plug
(2 rings and a tip
), not one that is stereo w/microphone
(3 rings and a tip
) if possible. Avoid mono plugs too.
If you are going to convert a pair of headphones, look for one that is cheap, if they work, go for something more expensive and try that out, its all too easy to make a mistake and I wouldn't recommend buggering up an expensive pair. Also, get a proper jack, if you are in the UK, look at
http://rswww.com/ .
http://uk.farnell.com/ or
http://www.maplin.co.uk/ to name but a few good electrical retailers!
Other than that, if possible, I would ask to try before you buy, many shops may allow you to do this, because your handheld PC is very unique
(and a pain in the rear when it comes to audio accessories!
). Explaining the situation may also help. Remember, they want your custom too, besides, it looks good if they manage to sell a product. If you can't TBYB, take it home, try it out, if it doesn't meet your specifications, or in the meantime you have found a better offer, send them back within 28 days
(for most retailers in the UK
) and they will be happy to give you your money back.
What is the basic setup?
My 3D Max renders should help to explain everything.
Is this clear enough?
PLEASE NOTE, THIS IMAGE IS MADE AS CORRECT AS POSSIBLE, I DO NOT HAVE A COPY OF THE SCHEMATICS, BUT IF THERE ARE ANY ERRORS PLEASE INFORM ME OF THEM AND I WILL CORRECT THEM.
THIS IS TO BE USED ONLY AS A GUIDE
Also, if you want to hear music out of both earphones
(using stereo earphones
), I'd suggest soldering both earphone wires together.
What do you mean by "Microphone Activation"?
To understand, here is a series of pics, I know you rather look at creative photos rather than boring text!
Heres the culprit, circled is the contact that turns on the microphone, it is only
some jacks that enable it, others don't. It seems to be the ones with an extra "shorud" around the jack. watch the animation:
Other than that, just mix and match to see what headsets work with your device. The stereo one is manufactured by Motorola, but I haven't tried the mic on it yet, here is a link to the product:
http://motorola.digitalriver.com/servlet/ControllerServlet?Action=DisplayPage&Locale=en_US&id=ProductDetailsPage&SiteID=motostor&productID=34372000&Env=BASE
(more from Motorola, if you aren't happy with that choice!

I hope this helps!
