The wires are a bit difficult to solder, but it is not really difficult and it should work. Did something similar, by rplacing those terrible earpieces with something decent. The wires are color coded, so that left and right channels are easy to find.

You can also open the mic-piece (pry open the two end rings and it falls apart) and solder directly on the board.
[MDA III, XDA III, PDA2k, 9090 General] thecross:
Sounds like a pretty good idea...it shouldn't be that hard. Chip quik the old one off, solder on a new one that fits. Has anyone checked out how the default connector is soldered/mounted? I haven't even taken my BA apart yet, only had it a week or so, it looks like I will have to invest in a set of torx bits though. It would be great to solder on a standard stereo connector so I can plug in whatever I want, I don't see myself ever using the hands-free microphone.

edit:

I just pulled my BA apart and checked out the audio connector... It's some kind of SMD connector with 10 pins, only 4 of them seemed to be soldered down though. I searched Digikey for the part and couldn't find an exact replacement, in fact I couldn't find any audio connectors that had stereo and a microphone pin. I'm sure it would be easy to adapt a 3.5mm jack onto the board though.

Oh well... Not sure which pin goes to what, I guess an ohm meter would yeild which one is ground, but one would need to stick some vector wire onto the connections and check it with a scope while playing an MP3 or something to find out which ones were the stereo and the mic.

Damn backup battery... After I got it back together all of my settings were gone! Oh well, only had AIM, VLC player, and PHMregedit installed.
[MDA III, XDA III, PDA2k, 9090 General] mike freegan:
HAHA theres always one :P

Well, my FM transmitter arrived and works great with my laptop!! I also ordered a 3.5mm stereo extension cable off ebay. What I'm gunna do is attatch that to the hands free kit instead and then plug the FM transmitter into that. That way I avoid potentially destroying the transmitter as I won't have to cut that at all. Also, I will be able to use the transmitter on other stuff afterwards :D

Just waiting for my extention off ebay now. Should come tomorrow.
[MDA III, XDA III, PDA2k, 9090 General] mike freegan:
This is really difficult. I got everything here ready. Cut the earpices off, but couldn't get any sound. Even if I try and put the original earpieces back on I can't get sound. I haven't tried to solder them yet. AAARGH this is annoying!!! :evil:
[MDA III, XDA III, PDA2k, 9090 General] mike freegan:
PROJECT IS A SUCCESS!!

I soldered directly onto the circuitboard in the microphone!! It was really easy!

Now after the microphone, instead of crappy handsfree earphones, I have a 3.5mm socket where I can plug in my wireless FM transmitter, good headphone or connect to my tv/stereo!

In my car, I can play full quality music through the radio via the FM transmitter. When I get a call, it interrupts the music and the phonecall comes through my car stereo perfectly. There is no echo on either end of the call :D

Microsoft voice command makes playing songs easy! Better than any iPod. I just ask for the band I want and it plays it. No fumbling with buttons! Also, Media Player 10 with album art looks great on my dashboard!

Watching movies in the car on my XDA2s is awesome too. You can actually hear them now the sound is through the car stereo, so no need for a DVD player :D

[MDA III, XDA III, PDA2k, 9090 General] buzz_lightyear:
cool, congrats... ;o)))

I'm thinking about this for a long time, but i'd rather buy a female 3,5mm cable plug and cut off earpieces 2 cms after mic housing. those two wires goes then into the female 3,5mm plug.

then you can stick in any headphones, transmitter, connector reduction, etc. and you have the whole headset functionality + hq stereo output.

buzz
[MDA III, XDA III, PDA2k, 9090 General] mike freegan:
That Is what I did! I tried cutting after the mic, but it doesn't work. I think the wires were too thin, so I soldered my female 3.5mm plug to the chip board. It works a treat!

It looks really tidy! I had to make the hole in the plastic microphone case bigger, but there is no visible soldering. The wires are tied up so my car looks tidier.
[MDA III, XDA III, PDA2k, 9090 General] DotN:
That looks well tidy!

So let me understand what's going on here.

You plug the handsfree headset into the XDA as per usual:

XDA <----->mic<---->3.5mm Jack<---->FM Transmitter

Where does the mic sit so that it can clearly pickup your voice?

Also, I take it u still have to be able to reach the XDA in ya car so that you can trigger Voice Command?

Soz for the noob questions; just got my QTek 2020i yesterday and already starting to look at ways to "mod" it :)

I'm a .NET developer and one of the reasons I bought this was so that I could have a play with writting some media apps for in car use so what you've done here really interests me.

Does anyone know which of the three bands does what on the jack plug? (which is the left audio, right audio etc)
[MDA III, XDA III, PDA2k, 9090 General] mike freegan:
Exactly.

Erm, well I have my XDA2s is in a holder stuck onto the windscreen. The microphone just hangs about 2 feet from my mouth. It works amazingly! My car is quiet inside but even the little engine noise doesn't seem to interfere. I'm thinking of making a case for all the wires and stuff.

Yeh, I still have to press a button to activate voice command, but it's still easier than fumbling with an mp3 player. Also, I can convince gullible girls that my car is talking to me ;)

All in all, It cost £19 to build the whole car kit.
[MDA III, XDA III, PDA2k, 9090 General] Codiac:
Fantastic bit of work, looking to do something like this myself!

I do have one question though......

As you are using an FM transmitter, imagine you are tootling through town and you get a phone call, you answer it, you chat happily away, several other people are listening to (probably half) of the conversation on their car radios, office radios and maybe even store PA systems!

Or have I completely got hold of the wrong end of the stick?!?

Cheers :)
[MDA III, XDA III, PDA2k, 9090 General] mike freegan:
HAHA no you're completely right :lol:

I was worried about that, but then I thought that a) they'll only be able to hear half of the conversation and b) I don't really have anything worth listening to :P

I think that the transmitter is on some odd frequencies. It has a choice of 4, so I use 107.1fm I know theres no local radio on that frequency, and shops aren't allowed to sell these transmitters, so the odds of anyone hearing my conversations are really slim.

If my stereo had line in it would be a hell of alot better, but it doesn't. If I ever get one that does, I can just use a 3.5mm to 3.5mm jack instead of the transmitter :)
[MDA III, XDA III, PDA2k, 9090 General] DotN:
lol, i got line-in so sounds good to me.

not sure i like the idea of the mic sitting two foot from me though?! Shame you couldn't get the bluetooth working @ the same time then use that to pick up ur voice (perhaps phase 2 :))

Cheers Wayne
[MDA III, XDA III, PDA2k, 9090 General] mike freegan:
LOL, the idea was to make a car kit for as little as possible. Total cost: £15 :D

Don't forget, it's a handsfree mic, designed to work some distance from your mouth. I have spoken to it and you can't tell at all. I wanted sopmething where I don't have to wear/hold anything to be on the phone.
[MDA III, XDA III, PDA2k, 9090 General] DotN:
just a thought, I might look to put 2 standard output jacks - thar way I can have stereo - I can then just get a 2-jack > 3.5mm converter if I need to.

Do u think this will work???

cheers Wayne
[MDA III, XDA III, PDA2k, 9090 General] mike freegan:
3.5mm jack is stereo.
[MDA III, XDA III, PDA2k, 9090 General] DotN:
true but it's not what most audio inputs are expecting.

No real probs with using a 3.5mm jack but I think you'll have more options using a standard set of outputs - but hey, you've done it and it works so I'm not knocking ya! :D

Cheers chap...most helpfull! :)
[MDA III, XDA III, PDA2k, 9090 General] DotN:
Just to say that I take it all back and that I think the 3.5mm jack is the way to go.

this means less wires and if I really needed to split the sound into seperate channels I could use something like this right: http://www.maplin.co.uk/Module.aspx?ModuleNo=43086&doy=3m9

Cheers

[MDA III, XDA III, PDA2k, 9090 General] fishmedia:
Congrats ... this looks great

The reason you couldn't solder the headphone wires is because the actual metal is coated, you need to sand off the coating from the wire before you can solder. I have done this before.

However, your second option looks much better :)

I have been looking at doing this for music/video and handsfree but really want to just take the connection from the main bottom socket. This way I will be able to dock the XDA in the car and hide the charge / audio cables in the back of the dash, one to a 12v supply and the other to the stereo AUX in. (I have AUX in on the stereo, so no need for FM transmitter)

I guess you always have to press the AUX button or FM station to take a call?

Have you thought about taking a BlueTooth headset apart and using BT from the XDA to transmit to the AUX stereo? - I guess this can be for handsfree only.

And have you seen the BT kits that daisy chain the ISO block of the stero to take power and automatically cut the sound and use the car speakers when a call comes in? I think this could be mimicked cheaply using some sort automatic dectection audio switcher?

Nice item but I wouldn't be happy coughing up over £5 for delivery!

I recently posted a fully boxed P900 with THICK user manuals and charger and USB base station etc all wrapped in bublewrap; sent using Special Delivery and that only cost me £5.35!

Sorry, I just don't agree with making your money back by upping delivery...recently seen some people selling K750i phones for what looked like a good price (£199) but then charging £15 for Royal Mail Special Delivery + £10 REQUIRED insurance! Special Delivery wouldn't cost anywhere near £15 AND insurance upto £500 is included anyway.

Sorry chap...u've touched a sore point with me...can you tell? :)

Good item though :oops:

Also check out www.pocketpctechs.com for the # 15 and 16 adaptors as well The # 15 keeps the internal mic of the xda enabled while you plug in high quality headphones via a 3.5 connector. The #16 is a dual 2.5 mono audio with mic, plus a 3.5 stereo socket. I also use a cassettes adaptor for input into the car stereo. Seems to provide better sound than the FM SoundFeeder I had previously

For anyone with this device i really recommend what i did if your not thinking of changing your headphones every so often or plugging in the BA to an auxiliry device to the likes that have already been talked about.

I bought all my stuff really cheaply on ebay and it really does sound incredible, i know what sounds good since ive been an audio nutcase for years!!! Now im not saying that this is gona sound like a pair of 50mm diver headphones. but as u know a good pairs always £30 up

Heres what i got:

*Original headphones: http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=5810522289&rd=1&sspagename=STRK:MEWN:IT&rd=1

*New headphones:http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=5806094030&rd=1&sspagename=STRK:MEWN:IT&rd=1

I use the BA constantly as an mp3 player and movie player so i was really dissapointed with the quality of audio i was gettin from O2's earphones or any other i was using with my 2.5 to 3.5 adaptop.

Appart from the fact the O2 plugs are huge and only good for grandpa with his massive ears they sound absolutly crap!

Im using GSPlayer since it seems the best quality in terms of equalisation and sound reproduction. I like the fact when minimised it runs quietly and doesnt chew up resources like WMP or Pocket Music.

So to cut a bloody long story short i hacked off the mic on the original set, (i dont use the BA as a mobile phone cos it doesnt RING when someone calls me (All calls diverted to another mobile (How crap is that! )))

Anyways! so i unscrewed the cap on the metal tube (see picture red circle) cut off the 3.5mm plug on it. Drilled out the hole (see picture green circle) so that the twin 2.5mm jack cable fits through. twist and solder the cables together. Melted a piece of plastic bag over the cables so none of the soldere joints make contact with metal tube and screw up my lovly music, screwed top back on and PRESTO!!! Quick ey?

Well no. i dont know why (well i do) manufacters plasticote all the wires inside! It makes it a bloody nightmare to solder! ive tried all sorts of methods but still its a pain in the ass to get solder to stick to the dam cable!.

So after the struggle of a lifetime to get the cables mated and shoved back in the tube im left with eardrum kicking basslines and damn loud crystal clear highs! WELL CHUFFED MATE!!! :D

Id have to really crank up the volume, preamp and the EQ's on GSPlayer to actualy hear anything on the London Underground using the adaptor or the original headphones.

With these new headphones the level seems to match at just 3/4 of the volume, I cant max this out since it actualy hurts my ears. They are just so loud!

The headphones are dual, earphone and earbud design and look a bit funny but the sound you get out of the earbud is incredible. Yeah ok they look like a doctors stethoscope (however you spell it), but i cant knock them, and at a bargain total price of £10.97 cheaper than a standard set of earphones you cant match it.

I hope this helps anyone with wanting to get great sound out of the BA, if anyones got questions or needs some help id be glad to answer.

BA ROCKS!!!!

I broke mine already :P I think to fix it I will have to buy another handsfree kit anyway. I don't understand that ebay one. I gather you plug your regular headphones into the 3.5mm socket, but what do you plug into the 2.5mm socket to get a microphone? A handsfree kit?

The microphone is the last piece to resolve then.

[MDA III, XDA III, PDA2k, 9090 General] weasel:
I have an XDA2s to headphones adapter (not one of padlad's tho') and I have connected it to a n FM transmitter I got from eBay. It works fine but I get ONE HELL OF A LOT OF NOISE when the phone switches cells or GPRS is active (it often is because I use tomtom traffic).

I think the phone is interfering at the adapter connector because wrapping the adapter in aluminium foil has helped. Also, ensuring the adapter is "shielded" behind my car cradle helps. Loks a bit silly, but works OK (ish)

Can anybody suggest other things I can do to reduce/eliminate this noise?

Can anybody verify that padlad's adapter is highly shielded/insulated? I'd be happy to buy another adapter, but if it still suffered from "phone noise" it'd be a waste of time & money

Cheers

Chris
[MDA III, XDA III, PDA2k, 9090 General] mike freegan:
I'm hoping it is! I got no noise from the one I made myself. Perhaps its something to do with using the internal microphone instead of the one I use on the handsfree kit (kept about a foot away from the phone).

I'm buying his dual adapter so I can use a handsfree mic. I think its desogned to work from a greater distance than the internal mic too so works betterin the car.

PADLAD, it won't let me mail you! I just get delay notifications. Basically as you can't accept my paypal from a card I'm in the process of registering a bank. Should be done by tomorrow so I can send payment.
[MDA III, XDA III, PDA2k, 9090 General] weasel:
The noise I'm getting is the same type of noise as I get if I place my phone on top of my PC's speakers; not continuous, just when making/receiving a call & when switching cells etc. i.e. when the transmitter is active.

Interestingly enough, I don't get the same noise levels when I use a cassette adapter, so my FM transmitter may be to blame
[MDA III, XDA III, PDA2k, 9090 General] frigit:
I made my own handsfree unit by the following:

Cut the wire of a 2.5mm headphone with mic plug and solder two RCA plugs onto it.

I had a microphone from a car phone (any mic will do) and soldered that to the wires from the 2.5mm plug.

The RCA's fit into my audio gods equaliser which has two inputs.

When I want to play music from my mini or receive a phone call, I simply press the input button.

As in previous discussions, voice command works a treat.

Note to solder onto the coated wires simply leave the soldering iron the wire for a while (10 seconds or so) this will melt off the coating.

Works well for me as I didn't have an input on my radio.

Cost me zip as I had all the components (even busted headphone will do) took about an hour including tidying up the wiring.

Homemade hands free adaptor

I created one by ordering this:

http://www.mouser.com/search/ProductDetail.aspx?R=172-7426 which is a 4-conductor 6 food wire assembly. You could also order this:

http://www.cui.com/adtemplate.asp?invky=7729 very similar but I haven't tried that one. The one from Mouser doesn't plug in all the way (close though), but it plugs in far enough to work and I haven't had a problem with it.

Then you can go to Radio Shack and get a mono 3.5mm jack and a stereo 3.5mm jack (they have them at Mouser too) and follow this pattern:

tip=microphone

ring1=audio right

ring2=audio left

base=ground

You'll also need to get some 26 gauge wire to run from the 3.5mm mono ground to the 3.5mm stereo ground (unless you get inventive). Get yourself a soldering iron, some solder, a wire cutter/splicer and a needle nose pliers and you're set. Radio Shack has all that stuff.

I made an adapter that allows me to use any pc headset with microphone as a hands free set for my BA.

Good Luck!
