I started to work on my 2.5mm-to-3.5mm adaptor.
It is a reduction between four-pin 2.5mm jack male connector (on XDA2's side) and two 3.5mm female connectors - first for stereo headphones and second for the microphone.
It's done and it works perfectly. I've got a high quality big headphones with built in microphone so listening to WMA music is near-HiFi and even telephone calls are much better for both sides.
But the problem is : buttons. The original headphones supplied with the XDA2 have two buttons: red and green. XDA1 had only one button and that button was just interconnecting two wires. But with XDA2 I've tried all combinations of interconnecting all of those four wires and nothing happened.
I didn't dare to open the original XDA2 headset, but I'm curious, what would I find.
Is there something more complicated in XDA2 headphones? Aren't they just interconnecting two wires but rather sending back to XDA2 some complicated signal?
XDA2 connected to Car HiFi
I already tested to use the XDA2 as a source of audio signal for :
1) HiFi aplifier at home
2) InCarAudio
It works perfectly and the sound is great.
I also tried to use a better external microphone connected to XDA2 - and results are great also.
So my adaptor 2.5mmJack-to-Two3.5mmJacks is really usefull for me.
But I really can't determine, how those two buttons on original headset do work!
my headphones are broken so I dont mind taking mine apart - want a photo of the interior?
Take a good look at the 2.5mm connector on the XDA2 handsfree. You will notice that it actually has 5 pin connectors. The fifth pin connector is actually the metal placed on the inside of the black cylinder or tube where the 2.5mm plug's base is located.
I'm looking for replacement for Magician's (wired) headset coz I think the one that comes with it sucks (low audio quality).
Anyone can suggest good alternatives with good MP3 quality (enough bass,...) and also as the phone's handsfree.
Thanks a lot.
If you are handy with a soldering iron, cut off that stupid pair of earbuds and solder on your favorite headset (that's what I did) or you can buy 3rd party adapters. If you solder on new headphones, don't forget to get some of that really cool heat shrink stuff to put over the wires, it turns out very professional looking and very strong.
Hmm...nice idea.
Unfortunately i'm not good at soldering.
So it seems i'm stuck with alternative to find a good earphone+hansfree combo....
SOny Ericsson p900 headset
5x times sound quality, + only one with a microphone that fits the 2.5mm plug. I searched long and hard to get this answer as i cannot solder too
this headset is not a stereo one, rigth ?
There are some adapters that have a built in mic and you plug the 3.5 headhones of your choice into it. There is also a small adapter that is just for audio 2.5-3.5. It is true that the Sony P800-900 headsets are compatible with the Jam. Unfortunately I have yet to hear original earphones that are acceptable to me. I can't remember where I bought it, but the adapter with a built-in mic and 3.5 headphone jack is probably what you are looking for. I use one in my car. Maybe somone has a link for you?

But in this case, is there any high quality 3.5mm earphone that also work as handsfree for the Jam?
This solution uses the internal mic of the PPC Phone so you can use any high quality headset from your local hi-fi store.
Can you confirm that this doesn't mess up the stereo or do anything else weird?
I found it! This is the adapter that I bought for my Sony P800 years ago(works with Magician). You can use it to plug into your home stereo, favorite headphones and it even has a volume control. Mainly I use it in my car. I use it to plug my Jam into my car stereo and sometimes I use it to plug in the earbud for one ear wired headset communication. ENJOY!

I have that. I don't like it too much since it feels very fragile (including the thin wire) and the fact that it isn't a simple straight wire means it snga everywhere.
I only use that adapter in the car. It is good for people that can't make their own headset by soldering. I made a custom headset from Koss headphones and a Sony handsfree. That baby sounds really good, and I'm picky about sound quality.
Does the mic work? Can you accept and end calls using the button?
Thanks,
K
Yes, the above adapter works exactly as the original handsfree headset (+ volume control) except that you have to plug in a normal 3.5 plug stereo headphones. If there are other models out there without the reel thingy, I haven't found it.
Hi all
I have a MDA compact which I wish to connect to my car stereo as a handsfree unit. I have an auxiliary input for my stereo.
Is it possible just to purchase a 2.5 to 3.5mm lead for this? I have a gut feeling the mic won't work - please help? Is it possible to buy such a lead with a built in mic?
Thanks
Carl
Hi, I used to have a XDAII which I connected to the auxillary port on my car stereo, just like you suggest. It worked perfectly. When using the phone, the caller's voice woudl come out of the car speakers and the mic was powerful enough to pick up my voice even though the unit was mounted on my windscreen.
Unfortuntely, both the Wizard and the Exec automatically disable the mic when you plug into the headphone socket. Not sure about the MDA comact. Sorry couldn't offer more advice on your particular device, but I hope my experiences help.

I do have the same setup. I can confirm U the mic still work after U plug in the adapter but I normally use a BT headset when I am in the car.
OK, so I assume that if I purchase a 2.5mm to 3.5mm lead, the mic should work?

Yes. 8)
OK - did some work on this.
I decided to cut the earplugs off of the supplied headset, and attach a 3.5mm socket.
I now have a custom XDA mini lead
All works, however volume from car stereo speakers is extremely low. Any ideas? (Yes, I have checked car volume, phone volume and headphone volume!)
Cheers
Carl

Hi Jackleung, my mic is being diabled, and i am beginning to think that I may not have the right connector. I have a standard 3.5mm connecting the exec. Can you let me know how you have wired your device with the type of connector? You may be able to solve a longstanding problem of mine.
Thanks in advance.
I found my mic was cancelled with the Mini, hence the custom cable.
hope this helps!

I think my adapter is just a standard 2.5mm to 3.5mm converter. I tried 2 different adapter (one from Radio shack and the other one from ebay: http://cgi.ebay.com/USB-CABLE-headp...ryZ15040QQssPageNameZWD1VQQrdZ1QQcmdZViewItem)
Both are working for me (I will try again today and confirm U tomorrow), therefore I think yr problem is in the exec hardware itself.
To Carl,
Yr setup will not work since yr supplied headset adapter has at least 4 connection on the plug compare to 3 on the standard one. The extra connection is for the mic. If U cut the wire like this:
<---- X --- mic+volumn control ------ ear plugs
Then U can no longer use the mic w/ the custom wire. But if U:
<------- mic+volumn control -- X ---- ear plugs
then the mic on yr mic+volumn control will pick up the voice
hi jackleung
Thanks for the reply - the lead was cut after the mic but before the earphones.
This was because a standard lead with a 2.5 / 3.5mm adaptor didnt work.
My only issue now is the low volume!
Cheers

I tried it on my Imate Jam again. My mic on the Jam still works (eg: Voice Command via Cyberon Voice Dial. So do phone conversation) even I use my 2.5mm/3.5mm adapter to connection it to my car stereo.
Hi,
I did the same for me and a friend of mine with a Univer..er - Jasjar and connected this to an FM transmitter - We have excellent sound quality, volume and the you can still answer calls by pressing the Mic Button

check connections?
I have done exactly what you did, put a 3.5mm socket on the end of the included handsfree cable.. volume is fine, and i regularly connect it to the aux in the car, and multiple sets of headphone/speakers...
The best suggestion to your volume problem is to try again.. i know i had issue with the stereo channels getting screwed up (and even combined at one point) and it was just trial and error getting the connections clean..
You have to ensure that both the shaft and tip connectors on the socket are grounded to the shared ground on the circuit board.. otherwise the audio will probably be less than perfect.. check for dodgy soldering/connection.. coz i can assure you that your theory does work!

There is another topic on this here.
The person from there uses:
http://www.expansys-usa.com/product.asp?code=PPCPADPT02
which has two 3.5mm plugs.
Description: It has a 2.5mm plug at one end (this plugs into the PocketPC) and two 3.5mm sockets at the other end (into which you plug your 3.5mm headset or headphones).
My question was: could I put a standard 3.5 car kit mic into this 3.5 headset jack (the one with the mic)? Would the mic work if I plug it into a headset jack?
I assume the other one (headphones = stereo only) I will plug it directly into my car auxiliary via a 3.5mm to RCA cable, right?
I want to use my Himalaya as mp3-Player sometimes, and so connect it to some amplifier.
There is this 2.5mm TRS-connector, where you plug the headphones in. Does anybody know the assignment of the contacts at the connector? It can't be standard-stereo stuff, because the headphones carry a microphone in it.
Any ideas would be nice!
I purchased a 3.5mm adapter to listen at the gym. My first try was generic and I got no audio, this new set only gets one channel. I think it's got to do with a microphone.

When you get no audio from the headphones (with your adapter), is the sound coming from your phone's speaker? Usually when those types of adapters aren't getting the sound through, it will come through the phone's speaker. You might want to try the HTC adapter that came with the phone with a 2.5MM phone stereo headset. The phone seems to be very sensitive with regard to audio coming through adapters and other types of headsets...
I have that one and it works just fine
What about registry settings? Would the BT Audio program that turns bluetooth to stereo do anything?
