Using The nokia headphones on standard device?
 
To save me from carrying around two sets of earphones, I'd like to plug my n800 earphones into my laptop headphone socket, but is its "safe"?

I'm not expecting them to explode or anything :p , but I don't wanna ruin the microphone functionality of them by plugging them into a socket that isn't a input+output combo.

Cheers :)

I tried to use them on my laptop. They did not explode, but they didn't work right either. The signal gets weak when fully plugged in, sounds like some phase inversion/deletion effect to me. Signal becomes stronger when the plug is pulled out a little, but only mono then.

What plug does the N800 headset use? Can anyone upload a pic?

I know the N8x0 does not have Video Out {I wish it did} but it uses a standard 4 pole socket and jack normally used for multi AV out.

I'm presuming that 2 is used you the MIC instead of Video on the N8x0's

Ahhh. Probably what's happening is it doesn't go in all the way on the laptop, and as such doesn't connect properly.

I think 4 might actually be the microphone (otherwise wouldn't normal headphones not work on the N800?)

Actually, I think (1) is the microphone contact, since 2,3,4 are used by ordinary headphones.

Edit: on second thought, it could be (2). On ordinary headphone plugs 1&2 are physically the same connector, so as long as one of them is touching ground then the headphones would work. I'm just not sure if most ordinary headphone jacks have their ground contact closer to 1 or to 2.

I think that 4-pin connector is actually longer than a standard connector.

When my N800 arrives, I'll put the two next to each other and take a look...

No...physically they have the same length! The only difference is that there's an additional separation near the plastic of the jack to create an additional line...

Actually, I think they are non standard. My blackberry has a similar socket (stereo headphones + mic) and the plug looks the same. However, my blackberry headphones work with my laptop, whereas the nokia ones when plugged to the other devices do not.

?xxAMxx? showed photos on a thread Ultimate Headset until they release a BT headset for the N800. S/he had removed the pendant cover and soldered in a good headset. I can't hear anything on the N800 headset. When I hold the N800 to my ears for a long time then I cannot sleep. Maybe it has something to do with 2.4 GHz. I have heard that 2.4 GHz is also the wavelength for a microwave oven.

Perhaps someone could take a look at those photos and ohm out the soldered posts with the 4 rings on the plug. Maybe this would help us determine what ring is doing what.

I used to do things like that. But now I am buried in tsunami/earthquake relief. The N800 is a great help in this. If you are interested please see http://oouc.wordperfect.com.

In relation to using the headphone jack, I had been wondering if it is OK to plug an ordinary headphones, (3pin, 3.5mm stereo jack) into the audio-out socket... and the following post says that it is:

(also useful for connecting to desk speakers, stereo etc)
