Headphone adapter

Has anybody actually managed to use their own headphones using an adapter. Thinking of buying the XDA Orbit but I'm cautious about the usb headphone socket.
Thanks,
Ezman

the bundled headphones are absolute toss! i'd love to be able to use my own...

Expansys will ship the adapter on the 8th of December (http://www.expansys.com/p.aspx?i=138247) . I haven't found this adapter anywhere else and I don't know of anyone who has it (except one guy in this very forum???) so I can't let you know if it's acceptable and working as promised or not.
One thing that should be VERY interesting is if the radio reception is good with this adapter and a pair of standard headphones attached to it (and using the FM radio registry hack). Has anybody (who has the adapter of course...) tried it?

well if it's the same as the spv m3100 socket then this should work, not that i have any confidence in my ability to successfully do it

Any progress on adapters for this device? It's a bit of a setback to not be able to use your own headphones with this device isn't it? Maybe I just need to get an ipod and shut up but hell, seems like a shame when i could use my old magician as an mp3 player.

Here's someone who uses the HTC S620 Audio Jack Converter.

i think so...

And is the sound level loud enough with this adaptor and a good headphone. I mean with the media player because for all other applications (FM radio, phone, etc...) it's OK.

Does this registry hack exist? I would love to be able to use my own headphones instead of the crappy XDA ones.

HKLM/System/State/Hardware/
set Headset to '1'
but the next time, your headset is connected and reconnected, the registry entry is again reset to '0'
it makes no sence to use the 'hack', cause all You will get is broadband noise without an antenna connected.
if you are familar with soldering, you can open the mic-housing (carefully with your fingernails), unsolder the headphones, and replace it with an 3.5mm female jack. So you can use Your own headphones, and the antenna is still connected.

No it doesnt, although i have this adapter in my car so i can run the mp3s off my phone, and the car stereo has radio anyway, which i may add never has anything good on anyway
Also, when this adapter is connected to the car, when someone rings i can hear them through the cars speakers but the adapter blocks the microphone signal so the person calling cannot hear me

This is actually quite easy to do, just buy a socket from Maplin for about £3 then solder between the mic and the crappy htc eadphones. Viola - I now have my senheissers back AND mic and radio function! OK I do have about 2 metres of cable to route around my clothing but that just adds to the fun.

Just did that last weekend, but when I popped open the housing with my fingernail, well there really is not enough room to fit a jack socket in there, with the headset that comes with the o2 orbit anyway, the mic is right in the way. I had a really slim socket all ready to go which I'd pulled out of a tiny broken sony radio. So I had to just chop the end off a 3.5mm extension lead with a nice ready moulded on socket. It was a 5 min job and looks like it was made that way, everything still works.

Headphones and Carcharger

Would it be possible to wire headphones and charger to a mini usb plug in order to charge and listen to headphones at the same time? When using Gps and headphones battery life is limited.

How about an adapter that provides a regular 12V DC jack for charging and a 3.5mm stereo mini jack for output to the car stereo AUX input?
Now that WOULD be useful. Maybe the Brodit active mount provides something like that?

Almost. If I was being picky (which I am I'd say the second USB port makes it a bit bulky. Ideally it would just have 1 USB and 1 3.5mm jack.
No rush though. I'm sure we'll be seeing a lot more.

Microphone lost
Hi, I've bought a splitter from here: http://www.valuemax.co.uk/product_details.php?id=7184

Adapter

USB adapter. I just love the Elf phone.The only things I am disappointed in is that I cannot plug in a set of external speakers. I cannot plug in to the charger whilst watching a film as I need the socket for the headphones...
Does anyone know of an adapter to enable me to do this please? I could get one made up from the diagram, however I would prefer to buy a custom made one.
Roz

maybe something like this?
http://www.expansys.com/p.aspx?i=127184

The Elf has only a USB socket, nothing else... No phono or whatever they call it... For me this is the only fault with a superb little phone.
Thanks anyway.

dont know about the elf but all other newer htc devices have a special usb connector which also carry audio
if your device came with a headset then yours do too
as they device dont support usb host so it cant use any usb devices
nm just saw my link was wrong :S

3Way USB adapter for HTC Touch/Elf
There is in fact a 3 way adapter available. I found it after a bit of a search. For some reason some of you seemed to think I was looking for a headset. The USB socket on the HTC Touch does not allow you to use anything else other than the supplied USB headset. however I want to use a set of Sony speakers for the sound to play MP3's and as I like to watch films in bed through ORB I like to be able to charge the phone at the same time. The process uses a lot of battery power.
The adapter I found has a stereo jack socket and 2 USB sockets the same as the one on the phone. So now I can plug in my head set and charger or charger and speakers in any form I choose.
If anyone else is interested here is a link where you can buy one for about £12.00 which includes postage: http://www.elitextreme.com/htcto31ad.html

HTC 3 way adapter
No Expansis do not carry one. The link I left earlier does. I have mine now. It is exactly what I wanted. Cost me £12.95. Well worth it.

Thanks for the find, but will it work even if it's for the TyTN and not specifically for the Touch?
And is it stereo as opposed to just mono?

i would asume that htc dont change the wireing of their miniusb connector flavour with each device it would serve no purpos and would cost alot for htc
i would asume that if stereo is in the miniusb connector when used for normal wired headset it would be using that converter
as it would serve no purpos for the converter to add the eletronics it would require to just take 1 channel and spit it in 2 without lowering the the volume to ½ because of the impedanc

extUSB extension Cable

Well, I've searched the forums and web and I can't seem to find a extUSB extension cable.
I found links for a male connector that requires soldering but there is no female connector to directly make an extension.
Does anyone one know where to locate a extUSB mini extension cable? I might end up having break out my old soldering iron otherwise.

I've never seen one...
There are the two male plugs on Sparkfun, but I haven't seen a female connector. Possibly pirate one from an old/broken phone on eBay?
Or, depending on what you're wanting to extend, get an adaptor (there's one on Amazon that this new user can't link to) and use a standard mini USB. But you'd lose some functionality, of course.

unless you really need to carry the audio then a normal usb extension cable would work just fine

Actually, audio and power are what I am looking to extend. This is to have one cable going to my car cradle while keeping everything else tucked away. I just ordered a couple extUSB data sync cables and a couple 3 in one adaptors for cheap on eBay. I plan on cutting and splicing the two cables together and then shrink wrapping the joint.
Hopefully all goes well. If so, I'll post some pics and the info used in making them.

3in1 11 PIN ExtUSB Earphone Handsfree Adapter for HTC
Finally appeared on eBay what I was looking for a long time!!
I think that is the same that you are looking for!
http://cgi.ebay.com/3in1-11-PIN-Ext...AU_MobilePhoneAccessories&hash=item3cabfd9d0b
Now I will not have a lot of wires apparent in the dashboard of my car!
not yet tested, I just bought!

Please let us know how long the cable is - thanks

Hi guys.
I bought 2 of them.
I'm using thet extension on my car, but when I connect to the USB power jacket, audio is affected by an annoying drone noise...
Of course audio backs perfect unplugging the power cable...
How to fix this?
Thanks!

I so far have not received my extension! But it should be on the way, because I live in Brazil and the request is coming from China.
At the moment I use an HTC adapter (http://cgi.ebay.com/USB-Audio-Adapt...ewItem&pt=PDA_Accessories&hash=item27b1f6236b) and I also have the same audio problem when I'm charging my phone in the car. Sometimes it gets very loud and sometimes becomes very low distortion. I found that helps a lot if you leave the phone's volume low and increase the volume of your car sound. Sound distortion is less so.
Once I saw here in the forum someone recommending a audio filter but I can not find the thread that had the link, but basically that's what we need.
If you find a solution please post here!
When I get my extension I will test and post the results here too!

I also have that original HTC adapter, I bought it before.
With the adapter I have no noise, it's only difficult to raise 2 cable to the phone...
Otherwise, I think the filter is the only solution.
Could you try to remember any detail to search for it?
Check this: http://forum.xda-developers.com/archive/index.php/t-377996.html , it's exactly what we have to fix...

My extension just arrived! In this second!
Using the HTC adapter you do not have any noise? I have sometimes and sometimes not!
Anyway I think we need something like this:

Let's keep in touch until we solve it! I'll test my extension and post the result here.

Audio output AND charger using the micro-usb port

Hi,
I want to have only 1 plug to insert in the Samsung Galaxy S2 to have:
- Audio output
- AND power charging
This is possible by using the micro-usb port of the Samsung Galaxy S2.
This is how the official Samsung docks works: http://www.samsung.com/us/mobile/cell-phones-accessories/ECR-D1D3BEGSTA )
But I am not looking for a dock, I just want a cable ! (it is much more convenient than a dock)
This cable would be like this:
Code:
|---------> Audio output jack
Micro-USB <---|
|---------> Standard USB (type A)
Where can I buy such a cable ?
Regards, Chris

I guess you have to make one yourself. It shouldn't be too difficult.
You just have to solder a 365K resistor to the ID pin of the micro usb plug. Then solder The data pins and the ground pin to a 3.5mm socket. At last you need to solder the +5V pin and the ground pin to the USB plug.
I have to say I like the Idea of such a cable, I think i'm goibg to make one.

I got the official vehicle dock and the sound coming from the line out isn't so good compared to the headphone jack. I'm wondering if the components within the dock is to blame or the phone itself (kernel?)
If the OP does find a cable that does the job I'd be keen to know how it turns out.

I am very surprised, no one is manufacturing such a cable. I am sure there is a big business for it.
I have never soldered anything. It is possible to make 2, one for me as well ? I would be very happy! I am based in Paris.

The quality should be good, as Samsung is selling a docking stations to output the sound on a hifi system. Bad sound quality is not noticeable on basic headphones, but on a hifi system that would be catastrophic (so Samsung would not sell docking stations).

You need an amp to improve the sound from the line out since it is unfiltered and not treated through the phone's yamaha pre amp.

Ahh, the cmoy, very cool headphone amp. I have a DIY AMB mini3 with an Alien dac connected to my computer. Now with the info from this thread, I really want line out! Though I must admit, 2.3.5 with poweramp sounds really good.

Ok the Cable is finished, when plugging the cable in the phone automatically enters dock mode and outputs audio via the micro-USB port.
Quality is OK I guess (I will compare it to the quality of the 3.5mm headphone-jack output), but keep in mind that I'm not an audiophile .
The build quality of my cable is not great, but it was more or less just a proof of concept.

That looks very promising, thank you for sharing!
Keep in mind, line out is unfilter, unamp audio output, so the sound will sound a bit bland. One must plug an amp into it to "color" the sound.

Good on you, wurzelsepp3. As for the audio quality between the headphone jack and line out I'm pretty sure you'll notice it but it shouldn't be a problem if you just want the functionality.
I just tested the cmoy amp in my car and it sounds good now.

Excellent !!
I need such a cable too !
Can you post how you built it ? I am not good at electronics.
I guess you have taken:
- a USB (type A) cable
- a jack cable
- and a micro-USB
and then cut all of them to just keep the plugs. But then how did you joined the different cables together and how did you installed the resistor ?

Hai wurzelsepp3,
I like your cable could you please post more photos of cable end pins and give more details of connection diagram, it will help us to make one.
Thanks n advance

wurzelsepp3, can you send the description of you cable.
Regards

I made a little paint drawing to show the wiring I hope it helps.
I will try to answer any questions .

Thanks for Image
Hi wurzelsepp3,
Thanks for your Sketch, please confirm whether it is same for car dock mode and desktop mode only by change of resister value and please confirm following my comments
1) Is it possible to charge the phone as per your sketch through PC usb port and via car charger out.
2) Is it possible to hear songs from stereo socket out through stereo headphone.
3) Is it possible to connected car audio system/external sound system because i saw another link like this

Yes the only difference between car and desk-dock mode is the resistor value.
1) Yes the USB-plugs only purpose in this setup is to supply power, so any charger will do the job
2) Yes, but you have to keep in mind that the sund coming out of the micro usb port isn't amplified, so sound quality and volume are rather low, so you might wanna use an external headphone amplifier
3) Yes, as car and external audio systems have a amplifier it should work quite well.

Would something like this work?

Docking Station
Finally I made my own style 3 in 1 Dock station, includes Car dock, Home dock and auxiliary audio out with the help of selector switch. Conversion of car dock to home dock by sliding the selector switch,also possible to charge the phone from home or Car dock mode. Auxiliary audio sound is nice to hear and All items compacted in small case.
Thanks for all, to give me such idea and sketches.

Are all the micro-USB to 3.5mm jack you find on eBay the same? Do they have the same pinout/resistance required for use on the SGS2?
