headphones - MDA III, XDA III, PDA2k, 9090 General

hi friends
I have the oiriginal headset fot he BA and everything is working fine but when I connect some other model of the headphones one speaker doesnt work.
Used to try with the different headphones and I had same problem.
After that I took the 2.5 headphone jack and checked the wiring, ground is ok, ring is ok too but looks like that inner pin dont have the connection...
Weird coz original headset working ok.
Im suspicious about 2 possible reasons
1. original inner pin is a bit longer and thicker therefore other non original jacks dont have the conntact (but that should be a matter of 1/10 mm - they look the same, maybe non original is a bit smaller)
2. theres some electronic in the volume slider on the original headset which correct the "miswiring" for original headset so it can work, maybe to force you to buy original headset
any expirince with this ?
ty !

found an answer, connector is different :S

xda2 headphone work with xda2s

hi
i have an xda2s an have relised that the original xda headphones dont work (only one side of the headphone works) with this phone neither does the c500 headphones or the e200 even though there all 2.5, i have many brand new 2.5 to 3.5 converters but now they dont work on the xda2s as well i presume its something to do with polarity, my question is does the xda2 headphone work with the the xda2s, the xda2 headphones are the ones with the answer andend call buttons plus the dial.
thanks alot.
btw ive lost my original headphones to soldering wouldnt help
Mine don't work. In fact they don't even fit because the XDA2 headphones have a wierd plastic bit on the jack which means they only fit the XDA2.
thats weird because my uncle has the xda 2i and that fits fine into my xda2s and that two has the answer and endcall buttons as does the one i want to buy,the htc people make it very dificult by making the 2.5 headphones not work with some modles. does the supplied xda headphone that you have also have the end and answer button. thanks
yeh, i know wat u mean...i have the same problem with the 2.5 to 3.5 conveter...with only one earphone working...if u fiddle with the postioning you will find that i works... so the theory that i have come up with is that i think the connections on the "jack" itself is different to standard, if you look on the "jack" there are 3 rings around it, which is left speaker, right speaker and micraphone...so i think that the rings are in a different order so when u plug anything else in it uses one side as a speaker and the other side as a micraphone...Well at least thats what i think but im sure its pretty accurate...but im open for correction...and if anyone has a solution to the problem then let us know... im using some earphones from motorola with a 2.5 jack and they are working perfectly, quality is a bit better than xda2s earphones, but thats about the best i could do...
hope there is a solution soon, i guess we just need the right 2.5 to 3.5 converter...if there is one...
I also had the same problem. When I bought mine new PDA2K device I tried to use my old XDAII headset and you're right -- it doesn't fit and it doesn't work. On www.expansys-usa.com I bought the PPC Techs 2.5mm/3.5mm converter for headset and for stereo headphone -- no luck doesn't work anymore with my new PDA2K.
I have noticed one thing though -- as standard 2.5 mm headset from RadioShack now works without any problems! I don't know why is it happening but they didn't work before with my previous XDA device... I also don't know if it is good or bad for PDA2K.
Does anyone know the internal wirings of new PDA2K and has it been declared that it will be officially compatible with the standard 2.5 mm headsets (which will been nice of course if it was).
Pretty good converters IMHO can be found at:
http://www.pocketpctechs.com/
thanks for all your imput.
my original questions was asked because ive lost my xda2s headset and was wondering if this headset from ebay would work with my phone. as i said before i have xda headphones that fit perfectly into the socket but yet only sound through one ear. im not intrested in a converter ive had enough of them. if i get a working headset then i may try the soldering later on.
could anyone just check if this headset may be compatible with the xda2s
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=6411586495&rd=1&sspagename=STRK:MEWA:IT&rd=1
i know for sure the xda2i headphones work fine in my phone.
thanks for your help
No they won't. There's already a thread about this somewhere. I can't remember who said it but someone mentioned that HTC must have shares in the Jack company as they seem to change the adapter for EVERY handset. It's so annoying that the 2.5mm to 3.5mm converter doesn't work as I can no longer use my XDA with a cheapy iTrip in the car.

Wanted: A Wired stereo hands free kit.

Can anyone recomend a replacement for the standard stero handsfree kit that comes with the MDA Pro.
I've seen these http://www.mobilefun.co.uk/product/10098.htm, but was wondering if anyone knew of any better ones?
I'm also looking for such a headset. The one on your links looks nice, but is there a volume control on it? I can't see that.
The one in mobilefun.co.uk is just the same as the one came from the box.
There is no other alternative so far I could find....
Though I found one (and I ordered already) from
http://pc-mobile.net/pqtaa.htm
that is for a 3.5mm headphone/mic jack.
So, I will post again if this really fits the Universal....GOOD LUCK!!!
Cheers,
Yeah, the headset fits without any problem.
That is the same as the HP Ipaq 54xx/55xx/63xx/65xx, Toshiba e75x/80x.
Although its a bit expensive, USD33 including postage....
Cheers,
Just out of curiousity, what happened to your hands free kit that came with the unit, guys?
The original one comes with the package is excellent except that it is too lengthy and the pair of earphones always messes with others.
I would like to have a single lead earphone that I can change to stereo when I want.
So, the one that I just got is perfect but it is quite easily to be damage....
Cheers,
:twisted: :twisted: My over excited dog snagged them with a paw when I got home from work and I think she snapped the cable inside the sheathing.
Wired headset with headband with wires
Can anyone recommend a headset for the Universal that
IS NOT BLUETOOTH
Has a headband with good sized speakers, not earbuds and dangly wires
IS NOT BLUETOOTH
Microphone, PTT switch, volume
and isn't bluetooth? i.e. it's wired to the 4 pole jack?
Thanks
Nick
Hi Chris,
Thanks for the info!
I have one of this headset that I bought few years ago for my XDA/Wallaby (with the 2.5mm plug). Yes, its very easy to be damaged (very delicate) but yet mine is still functional until now. Some part of the wire is already torn and I have to put some tape on it.
I use it mainly to connect my XDA/Wallaby to my car stereo system.
Thanks that you share this info, now I know that there is a suitable version for the Universal as well.
Do you mind to confirm back that the headset indeed works perfectly with the Universal:
1. The call answer button
2. The microphone
3. Volume control
4. The stereo jack
I will definately get one if you can help clarify that every point is working fine. Thanks in advance.
Yeah. Everything is fine altough the answer key need more practices.
Good to hear that the info is usefual.
Cheers,
Thanks Chris!
The answer button, you just press it once to pick up a call right?
What special practice do you need?
I sticked my old one (for the XDA) in my car dashboard near the stereo system. So when the phone rings, I just press it once and the call then will be in the car speakers. The microphone is not that great, ppl usually complaint me that my voice is so low, but guess what, they indeed can hear me.

This is exactly what I'm trying to set up in my car,how do I do it? I tried using a splitter (one 3.5 mm male plug with two female 3.5mm openings) and running one end to my car stereo, and the audio from the call comes through the car speakers nicely but I can't use either the mic from the included (in the box) headset for voice nor will the device's mic work...

Problem: Stuck in headphone mode after using 3.5mm audio jack

I was listening to music in my car today with my Sprint TP2 hooked up via the 3.5mm audio jack. When I disconnected the phone from the jack, the phone remained in 'headphone mode'. I knew it was in headphone mode still because it displays the little headphone icon on top and I could not hear any audio unless I reconnected the 3.5mm jack. So basically, I can't call anybody from my phone right now unless I hook it up to some speakers via the 3.5mm jack. That or use my BT headset.
Things I have tried to fix the phone;
- Unplugged and replugged in the 3.5mm stereo jack numerous times.*
- Soft reset
- Removed battery for 30 seconds and restarted
- Connected BlueTooth stereo headset and disconnected
* Extra weirdness; Gives me a voice commander error when I reconnect the jack. Voice Commander is not even enabled.
Nothing worked. So I just did a backup of my phone and I'm going to attempt a hard reset. We'll see if that fixes it.
Update: Right after I posted this thread, I tried plugging in several different devices with 3.5mm jacks and the headphone icon disappeared. However, I still did not have any audio. So I did a soft reset and surprise surprise... audio is back!!!
Anybody else encounter this bug? I'm not sure if it's a software or hardware bug, but it's definitely a bug.
guys, do you mean you have already have the 3.5mm specification tp2 ?
i didn't see it yet..
sounds like a hardware issue? especially if the soft reset did not resolve the issue...

Sprint and Verizon versions of TP2 have a integrated 3.5mm jack.
I just had the same problem being stuck in headset mode
I tried a soft reset with no luck so I was pretty sure it was something physically wrong. Instead of plugging my headset all the way back in and taking it out, I used the tip of the plug (like a Q-tip, 1/4 of the way in) to see if there were any sensors or metal still depressed and after a few light sweeps, the headset mode icon disappeared. Keeping my fingers crossed, I didn't use the 3.5mm jack for the rest of the night and I was able to use my headset and removed it without a problem this morning.
Ultimately this is most likely a physical issue, but I'd rather not send my phone in for a replacement (even though this would probably qualify as a manufacturer defect). Hope this helps if anyone experiences this in the future.

It is a hardware issue and is common to most 3.5mm jacks. I had also experienced this last year with my Treo Pro and since I really wanted to know the problem, I opened up my phone and voided all warranties. Inside the 3.5mm jack there's a lever type copper that bends to make contact with another copper metal, some kind of switch that's supposed to connect and disconnect the contact between these 2 metal pieces whenever a head 3.5mm plug is inserted.
What happened is when you disconnected the plug, the metal that's supposed to bend back to it's original position never did. That's why it's permanently stucked in headset mode because the phone thinks the plug is still inside. This probably happens due to age and possibly has something to do with moisture and rust, not to mention that copper is highly malleable.
Sad to say that until now this technology hasn't changed and is still being widely used. Hopefully someone will give this issue a real solution.
I had this problem recently and took a dry q tip and rubbed it back and forth across the little pin on the bottom of the headphone jack until it cleared up the problem.
Does anyone know if a USB to 3.5mm headphone jack adapter works on the CDMA tp2? I'd really like to use regular headphones but don't want to jeopardize getting my phone stuck in headphone mode.

Yes, the USB headphone adapter works on the CDMA versions. If you plug in a second headphone set to the other open port, which ever one was connected lastly will be the one to have sound.
Fixed the problem!
I had to disassemble the phone, voiding the already expired warranty and solder the contacts together on the audio jack. I can't use a 3.5 mm jack anymore, but I can at least use the phone now without always using a bluetooth. I'll get a usb adapter for when I want to listen to music.
Here is a picture of the contacts I soldered. I used a 20 w soldering iron, I wouldn't use anything larger.

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!

Type C Port somewhat broken ?

Hello Mi6 Owners
Im quite happy with my Mi6, but ive noticed something which is very bad.. Since Mi6 doesnt have a headphone jack it ships with an adapter.. Well I've lost that original adapter, and then a few days after i lost it ordered an replacement.. That replacememt worked for a few days, but the cable on that one was pretty flimsy, so it kinda broke amd i returned it.. Then i ordered some nice looking cable, and i plug it in, and it doesnt work at all, no headphones recognized and no sound coming from them.. So i thought the cable was trash and i bought one from a quite known brand where i live, in a local store here, and again it doesnt get recognized.. But i noticed (Note that all cabled i ordered said, they were compatible with the Mi6) that when i plug the headphones in the plugged in adapter, i get some weird noises, like when you rotate a 3.5mm jack in its port, some weird sounding noises, but thats all noise i get out of it... So is my port broken ? Charging works completely fine.

That's a weird one.
Hopefully its not broken as it seems to be okay with everything else.
I have no expertise on this but I have two suggestions that won't hurt you.
1.a. If the phone isn't playing music from the speaker then it has detected the headphones. It sounds stupid but on MIUI if you put the phone on silent the volume of music goes to 0.
Double check you have turned the volume up a bit and not on 0.
That's the kind of thing I would make a mistake about....
1. Use something very thin and very gentle (don't scratch anything) to clean out the port. It could be a piece of dust or something.
2. Does the port work for data transfer to a PC? If so then the data pins of the port are working.
3. See if you can borrow someone's adapters. But remember different manufacturers switch around the pins inside the phone and adapter to make only their adapter work on their phones. Its actually really awful they can do this as the whole point of USB C is to standardise everything....
Mine however works with the google pixel adapter so some of them will work
Hello, thanks for your reply
1. Its not getting detected.. So i plug them in, the sound goes through the speaker, as if no heaphones are connected.. The only sound i get from the headphones is when i twist them around in the adapter, a bit, like some weird noises, but definetely not from the music playing (but the adapters ive boight clearly say they are for Mi6)
2. Data Transfer works without problems.. Pc detects it and can copy files in both ways no problem
Those USB-C to 3.5 are a NIGHTMARE, mine was acting like the one you have... if you headset has a detachable 3.5. You can buy a usb-c to 3.5 so you avoid any adapter..... But in the end is cheaper just to get some cheap BT headset. Jbl, Phillips among other sell BT headset for not a lot of money.
Hello, i own a xiaomi mi6, but my model was with main MIC damaged so i have replaced It. Now main MIC works fine and charge working too. The only thing that does not work is the audio output of headphones. Can someone help me please?
