XDA2 2,5'' jack PINout !

I didn't find here the pinout description of 2,5mm jack connector from XDA2.
There is stereo out, microphone in and two buttons.
I tried to buy 2,5mm connector, but it is not usable - connector itself fits to the XDA2, but the connector's body is too thick so the connector can not be fully plugged in.
So i bought some Nokia portable handsfree, which is also equipped with 2,5mm jack with four pins. So all i need is to know, how it should be connected.
I also bought a small plastic box, two 3,5mm stereo females and two little buttons. All of those things will be installed into that tiny box (plus the Nokia 2,5mm male connector). So this will work as an universal adaptor: from XDA2 to anything. I already bought big HiFi earphones with built-in microphone - it has two male 3,5mm jacks - one for stereosound, second for the microphone - so I'll be able to connect it to the XDA2 using my homemade tiny box and HiFi telephoning will become the reality ;-))
I'd also like to make a "homemade" simple car handsfree : I'll connect XDA's audio out to AudioIn on my car audio (also suitable for playing MP3 from XDA on car audio system). And I'll connect a standalone external microphone to XDA, microphone will be placed somewhere in the cabine.
Does it sound insane? Or realistic? Does anybody know the XDA2 jack pinout?

this is xda1 but they are suppose to be able to use the same headphones
so it would help a bit
even though the xda1 dont support the 2 button thingy

Hey, as I trashed my cable I had to find out a little bit about the connecter
I write this from memory, so please handle with care ;-) :
from top to bottom
top ring - stereo out (left or right)
next ring - stereo out (right or left)
next - microphone in
next - ground
metallic ring in the inside of the connector - phone switch
By the way.. these pins are protect versus each other.. you'll have some tries..

The truth is that I can use the system connector instead of the 2,5mm jack.
AudioOut and MicrophoneIn pins are on the system connector as well...
So meybe I'll make SystemConnector-to-3,5mmJack adaptor ;-)
Or is there a difference?

Ehm..I had simply buyed a 2,5 to 3,5 Jack and cut a piece of it to fit into phone:

Well, OK. But it is only a stereo out, you don't have a microphone in. I'd like both of them plus those two buttons (red and green phone button)...

this one have the mic but dont support the pickup and slam down of the phone

well if you wanted to connect something else to the sysconnector you would not be able to connect something like charger or GPS
then imho it would make more sence using the 2.5 connection which cant be used for anything but sound anyway

Well, I am looking for such a device, but then one that will work with the XDA2/MDA2
Because I would like to use my own B&O headset, but would like to keep the phone function with microphone and answer buttons
So if somebody would like to spend an hour on the web for a detailed surch :wink:

make it your self...
takes less than 30 minutes (if you know how to use a solder iron)
I did it and I am trulty happy with it.
Alex

but is it not a problem that the lengh of the 3.5mm headset get added to the length of the wire from the device to the buttons and mic
i mean the mic need to be able to reach ones mough but the lenght from ones mouth to ones ears are not that long and with the added 3.5 mm headset lenght it would seme to become a wire mess?

Yes and No...
Yes if you do nothing.
No if you wrap it up a little.

well if you wrap the wire you will create a coil line effect
and that damage audio quality
just kidding i'm not a real audiophile

It seems that info in xda-developers.com/connectors/ is aplicable to XDA I.
XDAII headset has 2 buttons, answer and finish.
I'm specially interested in the 22pin pinout, that I've told IS DIFFERENT from the XDA I.
Can anybody point me with updated info on XDA II conneectors?
Thanks

Alex,
This is correct. The XDA II uses 5 pins instead of four. The switches are both connected to the 5th ring on the inside.
Until now, I wasn't able to find this connector.
Seems it's only used on the XDA II.
The diagram of the XDA I connector is correct, only the button isn't connected over the microphone to ground. So if you only need audio and mike, use that schematic.

Blue Angel audio connector?

Hi,
I want to connect an external speaker and microphone to my Qtek9090. I thought the easiest way to do it is to simply cut the headset wire, plug the 2.5mm connector in and connect my speaker and mic to those wires. I have taken apart the headset that comes with it and there's the following wires in it:
wire1:
- blue
- copper(1)
- red
- red/green
wire2:
- white
- copper(2)
From taking apart the volume slider I think blue and copper(1) are the wires for the audio (L&R). But I'm not sure. I can't figure out what the mic and ground wires are :?
Does anyone know more? Anyone tried looking at this?
Grtz,
DUTCH

just feed a low level audio signal to the wires. You should distinguish left and right. The remaining one must be the mic....

or...
buy an adapter. Both expansys and proporta.com sell adapters.
Nigel

I've been searching for those adapters and found many. The only problem is: none of them have a microphone connector :? .
Now I might have an option here, but i'm not sure this one suits the Qtek9090 (Blue Angel) I have: if I use this one. I could connect my speakers to the stereo 3.5mm headphone jack and my microphone to the mono 3.5mm headset jack.
The only thing is: what part of the headset connector is the microphone? The tip?
Grtz,
DUTCH

Do you know if it's compatible with nokia headset ?
like this one :

No, I've tried with a Nokia wired headset and it didn't work at all.

I ordered the audio connector mentioned (this one).
When recording a note for example everything works just fine, BUT when in 'phone mode' (making a phone call) it doesn't work.
Anyone got a clue/solution for this? Or should I start thinking about making this work via the 22-pin connector?
Grtz,
DUTCH

9090 should support audio from the bottom connector. I assume you want to use it in your car. If you want to connect a external speaker you should amplify the signal. There is a DIY carkit on http://wiki.xda-developers.com/wiki/Connectors . Maybe this could be handy. Also my phone supplier told me that in about a week there will be a complete carkit WITH decent Carcomm cradle and GPS connection (all wired so no BT connections needed). I will buy this when it is released so will keep you guys updated.

if I use this one. I could connect my speakers to the stereo 3.5mm headphone jack and my microphone to the mono 3.5mm headset jack.

I purchased this one for my old TMobile xda I and the Blue Angel.
Both are headphone jacks and niether cna be used for a mic. There is a built in mic and mute button (that you have to hold)

Here's the headset pinout + Where's tha audio in the bottom?

I used to have the original XDA (T-Mobile USA). I just bought the Cingular-branded Blue Angel (btw, they come unlocked).
As many have stated, the pinout for the headset is different. Here's how it's set up in the Blue Angel:
Sleeve - Ring 1 - Ring 2 - Tip
Ground - Out R - Out L - Mic In
As opposed to the original XDA:
Sleeve - Ring 1 - Ring 2 - Tip
Ground - Mic In - Out R - Out L
Now, I really need help to find the Audio in/out pins in the bottom connector. As far as I know (I checked), pin 1 is no longer Mic In.
Also, grounding pin 19 does not turn off the internal mic and speaker.
I'm a pro journalist - In the old XDA, the Mic In in the bottom connector gave me amazing sound from a Shure Microphone (through custom made cable with a line matching transformer).
I desperately need to know where's the Mic in and Audio Ground in the bottom connector. The Mic In in the top headset connector doesn't provide clean sound.
Thanks everyone.

Hey Uspino,
I got the same problem. But i find out that the pinout for only the audio on the bottom is the same as on this page :
http://wiki.xda-developers.com/wiki/Connectors
I hope anybody can find out wich pin is the mic. This weekend i will try out, so maybe monday i have an answer.
Pin 12 builds up a voltage of 3V to 4V when you make a call.
BTW, do you have a loose 22-pins connector for the mdaIII and can you tell me where i can buy this? Now i take the connector wich is shiped with the MDA for charging. I confirm the pinout you find out for the top headset.
Thanks anyway!

Fix Sennheiser HD205

I was handed down a pair of Sennheiser HD205 headphones. I had used them a few times before and they sound awesome! However, since I got them they make my music sound weird. For example, sometimes it turns every song into an instrumental version or it is really soft and will get really loud if you jiggle the cord right.
I cut off the jack and found 4 wires inside. 2 copper wires, 1 copper wire painted blue and another copper wire painted red. I removed the paint using acetone nail polish remover and fine sandpaper. Now that I have the exposed wires, I connected them in a new 3.5mm jack from radio shack. I think the colored wires are + and the unpainted copper wires are -. Note these wires are actually bunches of wires with tiny radiuses.
Sadly, when I connect the wires in I still have the distortion problems. It mostly has to do with losing the vocals. If I move the balance on my computer to all right or all left it will sound perfect. If I also connect the former red bundle to the ground of the 3.5mm and the former blue to either the L or R I can get mono.
I am thinking of cutting the wire higher and repeating the acetone procedure and rewiring again. Will that work because I don't want to keep cutting and cutting and eventually cut the whole wire to small pieces!
Your help is greatly needed and most appreciated. I really think these headphones will complement the voodoo sound on my I9000 nicely

187 views and nobody has any idea?? or needs more information for a fix recommendation??

Balancing audio?
I know this is probably a bit late. But i had a similar problem. My Sennheiser HD205 Headphones Started acting weird. They have an excellent sound of them and are really comfortable for someone like me who would wear them for a long period of time. Recently I had to get the cable fixed that went into the actual headphones because if they moved ever so slighty all sound was gone. I got them fixed and then the sound went weird the next day, when ever I played a song with a heavy bass, once the bass part came on the whole song was muted until it stopped and the vocals were distorted, then I was playing around with the sound settings on my computer and i noticed the audio balance was a bit off then usual (Left=78 and Right=78) so I brought them back down to 50:50 and it was all better . I thought maybe you should try that, seeing as nobody else left a suggestion! (If you dont know where to find the sound setting on your comp, go to: Control Panel>Hardware and Sound>Sound, and a window should pop up. right click on the speaker output you use (its called Speaker by default) and click properties then click on the tab properties and balance it to 50% on both sides) NOTE: Make shure your not playing any music (eg. Itunes) while your doing this. it MAY stop the program from working! Good Luck!

Hello,
I had the same problem. Unlike most headphones, the Sennheiser HD205 uses two separate ground wires, these are the two uncolored wires. The red one is for the right (the pin that's closer to the middle) the blue one is for the left (the pin that's further from the middle). The colorless wires both go to the ground pin.
I connected them this way, now I don't have any distortion, and I can hear the vocals loud and clear on both sides.

Sounds like you don't have ground connected to the signal source (jack).
If the jack has 3 connectors (tip + 2 sleeves) the wires go like this: tip - blue, first sleeve - red, second sleeve (furthest from the tip) - ground (usually golden).
Try an connect the two sides separately and check if they work individually. Only then connect them both. If the cable doesn't have any shor circuits it should work just fine.
Good luck!

Does anybody has the HTC RC E240 pinout?

I've got HTC RC E240 Headset. Suddenly the buttons stopped working. I've opened the remote just to find that it has 4 contacts but there were 5 colored wires. There was no place for the green wire.
Here's the scheme of what I have found after opening the remote. The numbers represent the wires and where they pop up on the jack. It looks like wires 6 and 7 are not connected to the jack at all. Need help for assembling this accessory again.
