Hi,
I'm only 13 and a proud owner of an O2 XDA 2.
This I what I need help with.
I would like to place my USB docking station on top of my subwoofer, and connect my XDA with it (only for audio purposes only).
I've read some of the forums here, but didn't find much info. :?
Could someone tell me which pins, on the connector, on the dockingstation send the sound? I would like to add 2 cinch cables to these pins, and attach them to my subwoofer (to kind of make my XDA like an Ipod or another MP3 player, where I simply stick it into my dockingstation and start playing MP3s through my sound system).
Thanks,
Kind Regards,
Tony Schattat
Hi mate.
Note sure you could connect the XDA directly to a speaker as I doubt it would have the required power output (but I don't know much about this, just being logical).
Take a look at the following thread: http://forum.xda-developers.com/viewtopic.php?t=26489&highlight=
This guy has basically modified the headset to have a 3.5mm jack - I've then suggested (and intend on doing this) that you could put 2 standard audio outputs instead.
On reflection though, I think his suggestion may be better as it reduces the number of leads. If you then needed to split the sound out to 2 seperate channels you could use something like this:

Hi Wayne,
Thanks for your reply.
I would rather like to have a solution which is built in my dockingstation.
With alot of precision I was able to do the following.
1. Used http://wiki.xda-developers.com/wiki/Connectors for details.
2. On pin 19 on the dockingstation I placed a 10K SMD resistor (as the standard ones are too big), connected to GND, as stated in the text.
3. Using a double cinch cable I soldered them onto pins 3 (CAR_AUDIO_R) and 4 (CAR_AUDIO_L), and both GND wires to GND.
But nothing seems to work.
I used the ohm-metre to check if the 10K resistance even came up to pin 19 of the dockingstation. I does. Unfortunately the XDA doesn't turn off it's built-in speaker and microphone, as stated in the text.
This basically simulates a car-kit for the XDA, doesn't it?
Kind regards,
Tony Schattat

Hiya!
Well if yer are 13 then it seems UK Schools are way behind German ones if they're teaching you about using Ohm Meters, Resistors and electronic theory already!
Ok, overall to me this whole precision soldering and resistor checking etc is all overkill for what you ultimately seem to want to achieve.
I've just bought off eBay the little 2.5 mm to 3.5mm standard headphone jack converter lead for about £2.50. I'm going to go nip into a shop or again off eBay and get a 3.5mm stereo to 2 phono plug convertor lead.
Simple case of then slapping that into the Aux input of my Hi-Fi amplifier, or my mini deck hifi etc and playing the mp3's through that!
No need for faffing around with soldering irons, and electronic theory and all that!
Added benefit is of course that through the hifi unit, I have full control over the audio equaliser functions and so will have the full spectrum of audio frequencies to hear the music - Your requirements states you just want to connect it to a subwoofer. Low frequencies are great, but you do need the upper frequencies too!
That will all set you back the grand total of about £5, and i've assumed you do have some audio equipment with an Aux input!
For 'constant' playback, when yer battery gets flat,... just plug the charger in!
Another benefit is that you can take the leads with you on your travels and setup the same at any of your friends houses with minimal effort!
I don't see the point of the route you are wishing to take - unless I'm missing something (I got in at 7am this morning after clubbing and up at midday, so im knackered!)
Cheers!
Hope this helps!

Hi Dennis,
Well the schools here aren't all that far ahead ( I think, because I`ve lived in Australia for 6 years)!
It runs in the family!
I was able to find some handy info on some dockingstations on google, but I'm not very sure.
Is it true that the serial dockingstations have an audio connector on the rear side, opposite of the power connector?
Is the audio connector on the dockingstation the same thing as the one, which is found at the bottom of the XDA (would it disable the built in mic and speaker of the XDA and send the audio through connector on the back)?
If this is true, could I simply attach a 2,5mm to 3,5mm converter to the back of the dockingstation and attach the converter to my subwoofer?
Kind regards,
Tony Schattat

Hi there Tony
I'm still not sure exactly why you want to connect your USB cradle to play music through.... seems pointless to me..
The method I described would be the easiest for you to 'amplify' the audio output from the XDA2.
I may be wrong but I dont think the USB cradles have an 'audio output' connector at the back, it's a bit pointless as these devices aren't devised as 'audio players' - so no, you cannot put the 2.5 to 3.5 mm converter on and then connect that to your subwoofer (signal is wayyy wayyy too small to drive a sub woofer) if there is an audio output at trhe back of the usb cradle, then I never knew about it!! and same again, you cannot connect directly to a sub woofer.
Out of the socket at the bottom of the xda2 in a 2.5mm size, is an audio jack. Get the converter to take that 2.5 mm and output it to a standard 3.5mm headphone socket size. Right, at this stage you can connect 'Hifi' headphones and enjoy your MP3's that way. If you now want your music 'louder' you need to convert that (now) 3.5mm output to be able to connect it to some audio equipment that can 'amplify' the signal and play through some loudspeakers (the 3.5mm socket to Phono converter lead). That will go to your hifi amplifier in turn to which 'full range'loudspeakers are connected. You mention 'sub woofer' .. You could then attach your sub woofer to the amplifier and you will only hear the low 'rumble' of the bass frequency content of the music (again, a bit pointless!). If that's what you want then at this point all will work but then what's your plan for hearing the mid range and high frequency elements of the music?
I'm just thinking that for your final 'aim' (to hear MP3 files on the xda through loudspeakers) the method you are using is cumbersome, time consuming and pointless when you can have a 'full range' output using the method I described.
Take a look at eBay for the connectors - and you'll find you should be hearing music in no time!

I recently have gone through two different Body Glove Sport Stereo headphones with some issues. I can't decide if I have another faulty headset or if the phone audio connector is the issue. The body glove headset is similar to the headset that comes with the 8125, but it looked more comfortable.
The problem I am having is this, the headphones only play in the right side. Messing with the plug on the headset results in some quick burst of audio on the left side and pulling it out a tad gives me some faint left audio and the right side audio goes out completely. It seems the plug and jack don't quite jive... anyone else experience this? It comes with an adapter for the "bigger jack" and upon trying one of my girls iPods, they work fine with the adapter in the mix.
My application is this... I listen to MP3's while riding my motorcycle and the earphones that came with the phone hurt my ears after a while. Plus they don't have the greatest audio quality. Looking for a comfy replacement, but the above issue has me scratcing my head.
Here is a link to the headphones: here
i think...
i think you have the wrong adapter. i tried using the slvrs adapter with my 8125 and it did not work same prob as you. i went to radioshack and got one from there and it did. im most absolutely sure is the inner wiring. what happens is that there's also a connection for a microphone on the 8125 so some adapters dont work.
http://www.pocketpctechs.com/main~unit~Cingular_8125-559~area~accessories~item~PPCPADPT21.htm
ps my friend got a mono one at radio shack and it worked for him both sides. hes not a audiophile but you get the idea, it has to be the connection of your plug.
The headphones in addition to be being stereo, have the microphone too, I think the paragraph in the page you linked clears up a few questions for me:
Most manufacturers create their devices allowing audio compatibility with only their specific brand headset or headphones. We have designed and engineered several different types of audio adapters to accommodate a variety of devices. Our unique audio adapters give you the freedom to use any standard 2.5/3.5 mm. 3 conductor headset and/or your favorite set of headphones.

It would seem although the Body Glove headset uses the 2.5mm jack, the internals of the 8125 are off enough that a select few aftermarket stereo headsets with mics will work with the phone. Interesting.
Upon further examination of the jack, it is different than the one that came with the phone. In spite of the BodyGlove being a stereo headet with a mic... just like the one that comes with the phone, the connector is different enough to not with aftermarket stuff I guess. Those dirty rascals!!!
The connector on the left is the one that comes with the 8125, the one on the right is the BodyGlove.
Searched and found this old thread. I went to connect my 8125 Wizard to my cars 3.5 jack using a standard adapter and it only came left channel.
Is there a more cost effective proprietary four-conductor jack to a 3.5 mm converter than posted above at PPC Techs? I was hoping to spend a few dollars.
I'm actually using my old Ngages audio cable to get Stereo sound out of my car stereo. It works but sometimes I can't use the mic on the cell phone to talk.
When it works it's really cool, but otherwise I gotta unplug the cable and use it like a regular phone during phone calls.
All,
From looking around I see that I can pickup various 3.5mm headphone adapters, but can't seem to find any line out (non amplified) adapters, do they exist?
If they do, does anyone have a link?
Thanks!

I think the OP is actually looking for something different, in his mind, but in actuality is what you guys have posted. The OP seems to think that different 3.5" adapters exist for connecting headphones or just a line out cable (for connecting to the input of an amp, for example). Hence his reference to "non-amplified".
But I don't think there's a difference. I think your suggestions above would get the job done also.
Well ...
I bought one from Tilt Depot ... which is just a 3.5mm plug at the end. I intended to use it with my headset, which turned out to be 2.5mm. I found a converter at Radio Shack, and while my headset does get the audio, the microphone is not being processed

Right, there is no "Line Out" on the Kaiser but these adapters would work fine to connect to a stereo. Just adjust the Kaiser volume to a lower level that has no distortion. I have found that it has a fairly clean output, my iPaq had a hiss with no audio, the Kaiser is dead quiet.

This adapter or something like it might serve your needs a bit better.
Ahhh... Well, that explains why I didn't have much luck finding a line-out adapter.. Guess I'll go for one of the normal stereo ones...
Thanks guys!

The HTC ones can be had from (I think) LA on Ebay for about $8/shipped. Lowest *I've* seen of them stateside.

Just a heads up.
I bought one of these from TiltDepot to use with my wired headset (not a fan of bluetooth, and you don't have to charge a wired headset).
Putting aside that the adapter is 3.5mm and the headset plug is 3/32", when I further adapted 3.5mm to 3/32, the earpieces worked fine, but not the microphone.
Any tips on which one is best? Trying to wirelessly send music to car speakers via the audio jack...
Thank you
you can look up the Motorla T505 - It is bluetooth and transmits to your car stereo using Powerful FM Transmitter. Mutes music when you get a call and resumes after. Calls come through car stereo as well. Or if you want check out jabra stereo headphones = I know that there are a few that have Headphone jacks out. My Jabra Bt320 would do what you are looking for or there is a Jabra stereo headphone set that looks like dog tags with headphone jack out as well. (Wish I would have foun that before I bought the Bt320 )

u can try the Motorola S705. It allows u to attach any 3.5mm jack to the unit. I have been using it for awhile and it works pretty good.
This sounds like a good idea. But, I often go the cheap route on devices like this. I shop at this website DealExtreme and they have a device like this for $20. http://www.dealextreme.com/details.dx/sku.8098 I saw some reviews on it that says the range sucks... it's like 10 feet or something but if I'm in my car with it, what does it matter. Anyways, that site rocks. There is a replacement battery on there for the Kaiser for like $7. http://www.dealextreme.com/details.dx/sku.15833
I personally use the iTech Clip (S38 I think...) i'd have to double check. I ordered it from ebay thought and it works pretty well. It was around $50 for me with shipping. The only complaint is the music sounds just a touch muffled when compared to listening through wired head phones. But you really don't noticed it unless you are doing a comparo.
I use mine all the time for when I go running and it works well.
plantronics 855
the plantronics 855 is a really nice stereo bluetooth headset. I got mine for $45 on sale, I think it goes for around $40 new on ebay. With a 3.5mm headphone jack part (radio shack $2), some wire (radio shack $3), a small amount of dremeling and some soldering you can turn it into a really small bluetooth to 3.5mm adapter with really great sound. (im using bose-in ear headphones and the sound quality is really good). I did it with mine and I love it. If you want instructions PM me.
If you just want to buy something then sony makes a really nice one, its like $100 but the sound quality has to be great.
Also make sure you do the A2DP hack to your phone (it's really just a reg edit in cab form):
View attachment A2DP_BT_Hack.zip
Sony Ericsson HBH-DS205 or DS220.
Generally rated very good -but some report brief transfer interruptions happening every minute or so. They come with a headset included, but thats connected to the unit via a 3.5 mm plug. I found one for a decent price on Ebay.

I just purchased the S705 on Amazon. What I liked was that it could charge while it was working as a bluetooth receiver. The only thing I don't like is that it doesn't have a hard on/off switch. I would much prefer to be able to leave the switch on all the time so that as soon as I enter my car and turn the car on, the S705 would connect to my phone.
As it is, I accept the limitation as it might be better all around that I have to turn the thing off rather than have it wasting it's charge every time I turn off the car.
Iv just bought a jabra 3030 dogtagbluetooth headset which has a 3.5mm audio jack on it so you could put it in a cup holder and buy a small 3.5mm audio jack cable to plug into the radio, I will test it out when mines delivered if you want ?
Hi I got my BT3030 today and must say it is amazing works great with tytn ii, sterio audio goes through aswell and a 3.5mm jack on the side so you can plug it into any form of audio output!
Sound quality is the best Iv ever heard from a bluetooth device and is allmost as good as my 5.1 at home
Only £30 from expansys if you get the £10 off from madoca or whatever it is.
I am still shopping for a solution but found this one while looking. Haven't tried any yet, thanks to all who posted suggestions.
Anyone else find this attached headset dongle annoying as hell?
Couldnt they have made this a sleek, rectangular snap on type thing, or better yet, install the headset jack on the device... argh.
Any aftermarket solutions?
You can get a sleeker adapter from xpansys for about 10 bucks (it's easy to find, just do a search on there). I have it, and it's pretty nice for using a headset. The dongle's good if you want to charge or sync your phone and listen to music at the same time, but I agree, it's clunky.

Received mine in 2 days via UPS.....WORKS GREAT for FM stations and Phone Functions!
Well it's large because of the number of connections on it. Two extUSB, one 3.5mm and one 2.5mm ... that's a lot of stuff.
I use the dongle in my car, I have it permanently there with my windshield mount. I have it hooked from there into my car speakers.
(and a microphone it is annoying that it doesn't go through the device when hooked up without one, but with this my calls go through the car stereo with a cassette tape adapter)
I also have a charger cable permanently connected to the dongle. So when I get in my car I just plug in the dongle and place it in the mount and I have all functions, headset, car stereo and charge.
I agree it is large, but for all the connections it offers, it is great.
When I am bringing my fuze to listen to music from it, I just connect a much smaller angle adapter I bought off amazon.
