Chinese headset wiring different? - General Accessories

I bought a Chinese phone called a k-touch hornet in v9 and I've been using it for about a week now. Got cm10 loaded on it and apart from the crappy battery life I'm loving it. One particular issue is going to cause me some trouble in future tho, and I'm hoping someone will have a solution better than mine.
The problem is that the pinout for the 3.5mm headset jack appears to be wired differently than I
US connectors. When using it with a US headset, the audio is garbled because one of the channels is grounded, until you hold the mic's button, then it sounds normal. Same effect using the k-touch headset on a US phone.
My conclusion is that the ground pin has been moved to one of the audio channels, and the mic moved to the ground.
I could rewire an extension cable to put the conductors where they're supposed to be, but I'm hoping someone might know where I can buy a pre-made adapter or maybe there is a Longshot chance i can modify the firmware to use the proper pinout.
Any thoughts at all are welcome!

Mini USB > 3.5 Jack?

Any adaptors that will allow me to use proper 3.5 inch headphone jack in place of the mini USB ones ( i dont like the in ear phones) checked ebay and couldnt see anything?
you want get one of these http://www.expansys.com/p.aspx?i=142090 - Mike
Ouch, that thing is both horribly badly designed and prohibitively expensive- it's going to stick out what looks like an inch by itself, most headphone plugs will add another inch on top of that- I need something that fits flush with the bottom of the phone (comes out at a right angle) AND supplies an input for the charger. One can only dream!
The orbit would make a great on-mains Wifi internet radio if such a gubbin existed- hook up some speakers, start TCPMP, sorted!
in which case if you don't like wires stop messing around and get a set of A2DP compatible headphones - the quality is very good, but far more costly than a cable addaptor - the choice is yours - Mike
Might have been worth while if I didn't use an iPod for all my portable audio needs- have you seen any A2DP compatible speakers around?
Looks like there are hacks out there, but no official products, the combination really would just turn the Orbit into an incredibly expensive Wifi radio! But where's the fun in just going out and buying a proper one!
Have a look at the products made by Parrot there are a few Bluetooth audio add on boxes, I fail to see the relevance to WiFi?? as the A2DP profile is Bluetooth - it even works on the T-Mobile MDA-CIII which has no WiFi - Mike
I say wifi radio because I listen to internet radio stations around the house using the Orbit, and the ol' tinternet comes via the wifi doohickey!
A2DP is, of course, a bluetooth profile and would be the method over which I get decent sounding audio from the Orbit to some speakers whilst still having the Orbit plugged into mains so the battery doesn't get sucked dry... that said I think the Orbit will last a good few hours streaming internet radio, although I have yet to put that to the test.
My other solution would be, as mentioned above, an adaptor that allows both the charger AND headset to be plugged in- I can't see this as being technically impossible.
With a brief cursory investigation I have discovered, I think, that the headset uses a proprietary 6-pin connection on the opposite side of the mini-usb connector. The headphones do not use the 4-pin standard mini-usb connector on the other side, but a connector that uses both should be reasonably simple to produce. Ergo it should be childs play for a third party to produce an Artemis dock that contains not only a connection to USB but a standard 3.5mm amplified microphone socket alongside a standard 3.5mm amplified stero audio jack... not to mention a button on the front of the dock for picking up calls and a volume slider if you really wanted them.
Call me crazy, but I want one of those!
You could try this

Might do the trick even if it is a bit long

Dear lord! You've made my day! Hmmm, a little jiggery pokery and I might even be able to incorporate that into a dock but it'll be fantastic for charging and listening to net radio at work- takes that little extra load off my desktop PC.
Cheers!
Glad I could help

Hi,
Does anyone know if the above would work with a set of mini stereo speakers with a 3.5mm headphone jack (like the walkman speakers i used to have, back in the day...) to listen to the FM radio while charging the phone from mains? Or would you still need the headphones plugged into get any FM reception?
Daft question maybe, but I wondered whether the device would just use the speaker wires as an antenna instead of the headphone wires?
It will work fine, I am going to use mine to connect my orbit to my home stereo and charge it at the same time.

2.5mm 3 pole jack plug
Hi,
Anybody know of an Artemis mini usb to 2.5mm 3 pole jack plug adapter which allows the connection to deliver audio and microphone capability ?
I would like to connet my Artemis/Orbit to the Autocom intercom system on my motorcycle . This uses a lead with a 2.5mm jack plug at the phone end and a 3.5mm jack at the Autocom system end. Both are 3 pole.
Thanks
P.S. hope you don't mind me jumping in your postings

Is this so you can listen to music from the Orbit? I've had difficulty on my bike with this...music cuts out and wont restart after phone call is over. In the end, I bought the Autocom bluetooth dongle and now bluetooth the Orbit to the bike. I get phone calls and GPS just fine, but I use a wired iPod for music.

Does this support the Artemis? It isn't in the list....
There was a posting for the mini USB PinOut some Time ago. Look in the wiki Section to find it. Here is what they showed up with.
Maybe This will Help someone to build their own Adapter or whatsoever.
Greetings
Jabami
so what was the general concensus with using Autocom? Did the 2.5mm jack work?
I want to avoid using the bluetooth option on autocom, since I might just as well go for a Scala bluetooth headset instead if the jack doesnt work...

Audio extension cable

I already posted on Diamond forum, but since there are no answers...please help
OK, got this YC A300 extension cable (http://www.clove.co.uk/viewProduct.aspx?product=B55C8C07-36B2-4A28-9A76-F11CB37A5A3A) with MIC IN LINE SUPPORT and wanted to connect earphones (discreet in ear earbuds) AND external microphone in purpose of making my headset as invisible as possible.
Now, I reckon I need to buy (make?) some adapter to put both of my devices into one 3.5mm jack found on YC A300.
Sooo, what do you think would this work with my setup (http://www.x50v.it/content/view/1159/69/)?
Again, my thoughts were if that Axim thing has 3.5mm jack with mic line in, my idea could work on Diamond too?
P.S. Since HTC support (like 3 countries where I sent my inquiry) don't know *hit about this (although they manufacture this audio extension cable) I wanted to check with someone who knows something before I find some audio service shop and ask them to solder me the adapter mention above.

Faulty Headphone Connection

May have to send my Desire back to TMobile. Supplied headphones do not work. There appears to be loose connection inside handset. To hear anything I must hold down jack connector and then the volume is very low, the minute I stop holding the jack it drops the sound. Anyone else finding this build issue?
Also the remote on the headphone cable will not operate. I did try the supplied headphones on another device then its o.k. so it must be the actual Desire at fault.
Your phone is probably ok!
I had exactly the same problem, but it's due to the headphone connector.
You should use a 3,5 stereo jack with 4 contacts (TRRS) instead of a the 3,5mm stereo jack with 3 contacts (TRS) which is present on all casual headsets.
You can sole it with an adapter cable.
More info in this forum: topic 6269599 and 667240
My remote doesn't work on my Desire too. But my remote on a friend's Desire works.. grr
Thanks for the replies. Fair play to T Mobile they exchanged my phone no problem. New phone now works perfect. So pleased I got the Desire.
I found a solution for mine, it was tunewiki which override the headset buttons by default.. <clever>

Jack problem

On my WFS jack connector jumps out about 1mm... it is big problem because it stop playing music. WHY? Does somebody have same problem?
Sent from my Wildfire S (root, cwm..)
i used to get this ALOT if i just use my standard headphones directly into the socket. even if it doesn't "pop out", the slightest movement of the headphone jack would cause it to "disconnect" and stop playing music.....VERY annoying.
I managed to "fix" it by simply buying, a cheap as chips headset adapter on amazon. I have no idea why this works, as the plug on the end looks identicle to the one on my headphones, but for some reason, if i use my headphones i get disconnects.....if i use the wired headset adapter then plug my headphones into that it works. no more disconnects.
like i said, no idea WHY this is the case, but it worked for me. i juse bought the cheapest one i could find, i think it was around £2 on amazon.

if your using the original headset, i would do as stated above or:
go back to the shop and ask a refund or repair.
if your using your own headphones:
try using your headphones in other devices (pc, mp3 player) and see if it does the same, if not contact the company where you bought your wfs if you still have warrenty, i would not accept this kind of hardware failure.
good luck with your headphones
GLORIS:
Well, i have Razer Electra headphones... it have support for HTC (mic on wire, 4-pin jack)
JACK ON BOTH, ELECTRA AND ORIGINAL HTC EARPHONES ARE SAME SIZE!!!
my theory: magnetic??? your jack from amazon is magnetic, check this now please
VitanyLTD:
phone is ok, original earphones from HTC connect perfect but others not.
YEP! HTC earphone JACK CONNECTOR IS MAGNETIC, SO WE NEED MAGNETIC 4-pin JACK CONNECTORS!!!!
best will be reduction JACK MALE 4pin to JACK FEMALE 4pin
AFTER THIS I HATE HTC FOR HARDWARE SUPPORT!
Looks my orginal htc headset is not orginal or something cus same thing happening to me.
that's a negative on the magnetism front :s
as I sayd... and headset adapter is magnetic?
no, neither the headset nor the headphones are magnetic. I can genuinely see absolutely no difference between the two plugs, but one works, one doesn't :s
then i don't know.
I to have problems with 3.5mm in car its loose any slight movement will turn off music. i will find an adapter to.
I need JACK 3.5mm 4pin reduction for my headphones.. On cable I have mic...
can somebody find it JACK 3.5mm 4pin male to JACK 3.5mm 4pin female? I can't find anything...
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=110760294384
just ordered this. according to the listing there are 3 in the pack, and that's only around £2.70. So if it works out well, and anyone in the uk wants one I should have 2 spare when they arrive, just let me know if you want one and you can have it. I'll try it out first when they get here though. From the description, it sounds like it takes the 3.5mm 4 pin (with headset) and converts it to 3.5mm 3 pin (normal headphones). So it should be perfect if you don't want use of a mic/headset.
My headset cable adapter works well to be fair, but the extra cable does make thigns a bit unmanageable, so hopefully this adapter will work out a bit better
I had the same problem. After trying different headphones, I decided to take a small slotted screw driver.
Just stick it into the slot and turn it a few times without too heavy pressure and now everything works nice!

LOL, you should be a doctor... a surgeon man ... just stick your knife in a man without too much pressure, and it works out perfectly ... lol ... or maybe a butcher better
Haha...yeah, that's how I deal with my problems xD
No seriously, I was really worried before I did it but it worked out fine!
those plugs for headphones 'felt' cheap the first time i plugged my headphones... they rly have little something that stops you from plugging propperly so you just roll it few times, i did it with my hp-s...just roll and push a bit... and i smiled just how u did it with screwdriver xD
but the main thing is, that it works... you guys decide: screwdriver or headphones jack xD
Sent from my HTC Wildfire using xda premium
I personally would go for a screwdriver and a hammer...
EDIT: I had that problem with a pair of Creative EP630 in-ear headphones (cheap eBay copy).
Since I bought my Sony MDREX-50LP (guaranteed original) never had that issue.
The sound with Poweramp is absolutely FANTASTIC.
Was so Angry when I first found this problam, I listen to a lot of music. I twisted the Headphone jack a couple of times and Voila!
Thank you Wfbml + b02!
Now I can enjoy my SteelSeries Siberia V2's as well as my Hi-Fi on my WFS!
Yes, I do have the Beats "Mod" Installed.
YES!!!
Sorry for digging up an old topic but I just had to say thank you so much for the screw driver fix : it worked like a charm and I can finally make use of my music again!

DIY FM Antenna With 3.5mm Audio Jack

This is not something new and have been shown many times in YouTube. It is interesting to have for any phone with 3.5mm audio jack that can be easily done within a few minutes. I do not use my headset with my phone so this would be a nice hack to have around to listen with your friends on some local radio without consuming your data plan and phone battery.
Find a headset that you do not need. We only want the part with the 3.5mm audio jack. Just trim it down to about 20cm in length and fold it in half and tie a knot at the end. I tied a lasso knot at the end just so I can adjust the length of the receiver later on though it may not help much in reception quality.
Tested several length from 1 meter all the way to 20 centimetres and found not much difference in reception quality for a fact that you will be using your loudspeaker to listen to the FM radio. The same with whether to loop or not to loop the receiver but looping the receiver gives it a cleaner look while maintaining the same reception frequency.
Putting your phone too close to a human body greatly interferes with the FM signal. On the other hand, placing your phone on a metal table may enhance the FM reception.
Perhaps those who have knowledge in electronics can shed some light to optimize this simple hack further.
Have fun...
I didn't know. Works like a charm !! Thank You
Doesn't work for me. When I plug in the trimmed headset cable with the ear pieces cut off, the FM App keeps asking me to plug in a headset. Works OK when I plug in an untrimmed headset and switch to speaker in FM App menu.
Is there a further trick to getting this to work? Are you using the stock FM App?
I had the same problem myself, and it stems from the fact that smartphones will interrogate any headset you plug in to check if it is suitable. There are basic stereo headphones with three contacts on the jack plug (from the tip they are left, right and ground) and should work on any phone regardless. But there are two variants of headset (i.e. those with a microphone) that use four contacts, the difference being whether they connect the mic on the third or fourth contact.
As of 2016 most manufacturers have standardised on one system (left, right, mic then ground), but there are enough older phones and matching headsets out there that use the alternative pinout scheme. For example my old Sony Xperia used L-R-G-M (the same as say Blackberry), necessitating the use of an adapter for certain accessories. My latest Z5 however, has moved to the L-R-M-G pattern, which means I can no longer use my favourite old Sony headset anymore, not even as plain headphones, the Z5 just refused to talk to them.
That explains why a dumb wire might not work with a smartphone, because it is looking for a signal loop on all four (or three) contacts to try and figure out what's been plugged into it. The solution is to short out the wires to fool the phone into thinking there actually is something on the other end. Simply bare all of the wires at the cut end of the cable, burn off the fine lacquer or cotton that is used as an insulation, then twist the wires together to short them all to the ground. Better still, solder them together and cover with a bit of heat-shrink for a proper finish.
Found some pre-made antennas in ebay, you can try searching for 3.5mm antenna. They look pretty decent. I am also looking for compatible antenna, if any, that is compatible for steven303's new headphone jack.
Edit: did some research and found that the 3.5mm steven303 mentioned is called '3.5mm 4 conductor' or 'TRRS antenna 3.5mm', you can try searching for them in ebay or look for similar ones lying around with wires long enough to be loops around to be used as antenna for new phones with the new type of head jack.
I got two item I think can be suitable for this purpose; search with the following keyword in ebay;
1. 3.5mm 1/8'' Male To Male 4-Pole 3 Ring TRRS AV Audio Extension Cable 1.2M/4Feet
2. 4-Pole 3Ring TRRS 3.5mm (1/8'') Male To Female AV Extension Cable 3FT/1M Black
I have an additional issue. I use my phone's fm radio feature with an old pair of headphones for an antenna and listen via blue tooth headphones when I'm running or just working around the house, etc. My problem is that as the phone moves around in my pocket, the movement causes the phone to think the headphones came unplugged for a second and the radio turns off. When that happens I have to take the phone out and turn the radio back on. This happens often enough that it is a pain in the neck.
A separate but related issue. With some old, non functioning headphone cables the phone doesn't think there is anything plugged into it. I am lucky in that my phone gives me the option to "Play anyway through speaker or bluetooth". So even though it thinks there isn't anything plugged into it, I do, and I have good FM reception.
Here is what I want: I want to know what to do to my old headphone wire so that my phone doesn't think there is anything plugged into it when it is, in fact, plugged in. I hope that makes sense!
