How to take apart headphone portition?

I am thinkink of taking apart this little piece with mic and two buttons on it and replace headphones with Sony fontopia. I really don't want to break anything. XDA DEVELOPERS! please, help!

why not just cut the wire right over the mic with buttons and put a female 3.5mm jack then you can plug in a normal headset there ?

Ok, I did. Now I can listen good quality music and not missing any calls. BTW, I love the way XDA2 handles calls, music stops when call comes in and continues right after done

does that on xda 1 too when you got ppc2003 on it

Can it be used in XDA I?

Hey all. I'm trying to do this at the moment. I soldered a 3.5mm female extension lead to the headphone socket but i've got a problem. I only have sound coming out of the left headphone.
I know it's not the hima because i opened mine and resoldered the audio jack just to be sure. When using a 2.5mm>3.5mm converter, sound plays perfectly, but when i'm using my modded handsfree kit, i only have sound on the left.
Can someone post some pics on how to properly solder a 3.5mm female extension lead to the handsfree kit mic portion?

Take a look at this

Hanmin, I love you.
On another note, i found this wiki page in the above mentioned thread that details this procedure. I rewrote it for readability (and NxJay-ness) but it's pretty darn useful.

2.5mm to 3.5mm stereo conundrum

Ok....I've fought with finding an adapter to go from 2.5mm to 3.5mm for ages now. Everything I've read indicates it needs to be 4 pole etc etc....I'm aware of that. However, every one I've tried is still producing mono output. For kicks, I've tried the following ALL with mono results:
-Blackberry Pearl stereo headset
-RadioShack catalog #274-004 3/32" to 1/8" Stereo Headset adapter (why wouldn't this work?)
-Just Wireless 08351 Stereo Adapter 2.5mm to 3.5mm from (Target/BestBuy)
-BodyGlove Stereo Sport Headset 7489401 (BestBuy)
Now, when I say these produce mono output, what I'm really saying is that there is only one channel of audio whatsoever...the other earpiece is totally silent.
Anyone had any luck finding something at a retailer without ordering online? I'll order if I have too though. Thanks.

remeber google is your friend!
(btw, this is a 4 pole connector, the reason why all they othere ones youve tried doesnt work is cause they were three poled and the contacts dont match up)

The specs on this RadioShack adapter is specifically 4 pole....I checked that first. In fact, the packaging description reads:
"Turns a 3/32" 4-pole wireless phone headset jack into a 1/8" stereo headphone jack"
Check this link and you'll see what I'm talking about: http://www.radioshack.com/product/index.jsp?productId=2603246&cp
I knew it needed to be 4 pole, and that's what I'm saying...every supposed 4 pole adapter I've tried hasn't worked.
Any other ideas?
NOTE: Also note I said I tried the Blackberry Pearl headset, which is also a 4 pole headset jack on taht phone so theoretically that headset should have worked perfectly.

i used to work at radioshack and i can tell you they dont carry any adapters that work with smartphones, i cant tell how many customers came in looking for the same thing.. the adapter on ebay works its just like the one i have

The problem is simple. Look at the base of the 2.5mm jack on the headphones that came with your phone, then look at the base of the 2.5mm jack on the adapter. You will notice that the base of the adapter is way bigger than those on the headphones and this prevents you from pushing the adaptor as far in the hole as it needs to be.
Stupid idiots at The Source were trying to tell me that it wouldn't work because of voltage...
Anyways, when buying an adapter, just make sure that the base of the 2.5mm is small enough so that it'll fit into the recessed 2.5mm in your phone. It is okay if it's just the three pin plug, it will still be in stereo.

TRRS Pinouts for Desire-like proper headphones without issues of direct plugging in

Sup all would anyone have the actual TRRS pinouts for the audio jack for the desire I would like to make a up a lead that will allow me to plug an ordinary pair of headphones in using a proper TRRS jack instead of a TRS jack. thanks. There are definately issues plugging in a headphone directly or maybe it is my unit faulty?
Edited, this topic will show you the best way to connect your headphones to your desire as some people will experiance problems with pluggin in normal 3.5 jack plug headphones, this is due to the desire using a trrs socket for the microphone instead of a trs socket that normal headphones use.

pretty sure it is:
tip - left audio
ring 1 (closest to tip) - right audio
ring 2 - data of some kind
shield - ground
Hope this helps

cheers for that, im having some peeps tell me that i can just plug in an ordinary pair of headphones into the phone without any ill effects, i am concerned that i will have a problem because headphones are trs jacks and the desire has the trrs 3.5 jack. can anyone confirm any details on this for me please

nah you can use a normal TRS 3.5mm jack with no problems. I guess that when you use a normal TRS jack then shield and ring 2 on the connector are both connected to shield on the jack so it adjusts the software accordingly. But yea, no problems.

cheers for that
edited, we have since discovered that this is not the case, please read the entire topic for the correct way to connect headphones to the desire.

standard 3,5 mm (TRS) headphones DO CAUSE ISSUES
Was about to resend my HTC Desire, because it randomly called, skipped music stopped the music, FM-radio freeze etc. from the moment I connected my high-end 3,5mm headphone (TRS type: 3 contacts).
No issues with the standard headset delivered with the HTC Desire (TRRS type: 3,5mm 4 contacts).
So, you might need a TRS -> TRRS adapter.
Anyone with other experiences???

Basically what I have found is that many of the normal headphones are not working correctly because it is a trrs socket that is used. To me this would mean that normal headphones shouldnt be used, I have tried various headphones but there are definately issues with them,
The main issue I was having was as you have said above and also the base wasnt right with them
I have since bought this
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=130384433476&ssPageName=STRK:MEWNX:IT
which arrive today and when I am using this in conjunction with my headphones I now have the proper base to the set and NONE of the problems I was having when i was plugging them into the phone directly......... they just didnt sound right, now using griffin smarttalk this i can definately tell the difference now especially in the base, also this unit will lower the volume and allow you to make a call automatically with built in mike, clicking it twice doesnt skip the track suggested instead it will ring the last number dialled in the phone so a bonus actually to me
the straight adapters ie trrs to trs are very nearly the same price as this if not more expensive so i would recommend this all day long to you. At £9.75 delivered bargain m8, bought late evening on the 20th arrived this morning what more can i say, but if you are having issues it is definately in my eyes because of the difference in the trrs socket to the trs socket,
the base is fantastic on this phone now, before it was terrible, now i just need an equaliser to remove some of it

When you speak of "normal headphones", are you referring to simple 3.5 TRS headphones, or headphones with a mic ?
Cause if the majority of the headphones (without mic I mean) won't properly work with the Desire, it's a major flaw according to me.

I confirm: TRS (3 contacts, without mic) do not work...
...I tried 4 different 3,5mm stereo headsets (TRS type, 3 pole, without mic). NONE of them worked correctly (phenomenons as described above).
When you plug a 3 pole TRS headphone in the Desire 4 pole TRRS headphone output, a short circuit is generated between the first 2 internal contacts (seen from connector input: ground + control line).
I suspect that the Desire firmware cannot detect/handle this situation, and so it causes random actions (prev, next, call numbers, stop, play, ....)
I suspect that this issue could be solved with a firmware upgrade....

there is no way they would release hardware with a 3.5mm socket that you cant plug a 3.5mm jack into right? the firmware does detect when you use a TRS instead of a TRRS. You get a different icon on your notification bar for each of them. As ive said before my AKG's have worked perfectly so far and have shown none of the problems listed above.

This afternoon I quickly tested my Seinheiser PX100 headphones with a friend's desire and the Htc music player.
It worked flawlessly. Volume was good and it didn't play/pause/skipped tracks.
As I said it was a really quick test so I can't say for sure that everything's was okay.
Nonetheless apparently a lot of people experienced problems with numerous headphones. To me it's really a shame you can't even plug ANY 3.5mm jack headphones with the desire ...
I hope a software update could fix this.

I also had this problem when connecting my Desire to my car radio using an standard 3.5mm AUX cable. Will this cable solve my problem or will my car radio not be able to recognize a 4 pole cable?
http://cgi.ebay.nl/3-5mm-Male-TRRS-...erAccess_RL&hash=item5d28c530c1#ht_1252wt_939

I think this might be an issue of certain cables not making a full connection due to the shape of the case surrounding the socket. I had no problems with my headphones, sound was good and loud enough although I could see how it might not be loud enough for some.
I did start having issues when I plugged the aux lead in my car into the phone. The lead has a large shroud that obstructed the plug from being plugged all the way in. This gave the same problems as described in other posts, skipping tracks and also crashing the music software at one point.
I replaced the lead with another that had a better fit and the problems went away but I did notice when I leaned against the lead while it was playing music in my car it started skipping track again.
I wonder what HTC have to say about this....

I solved those problems with this lead- i dont think the one your showing will work for you
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=220593400305
they come from china etc however only 5 days to arrive from ordering.
and I now enjoy trouble free music. I also have ordered the Griffin Smart Talk so i can listen to my headphones and be able to answer the phone as well however I didnt want to use it for plugging into a car stereo etc etc so i wanted a straight lead conversion.
Just a quick warning the first lead i ordered from this person was faulty, however i had also ordered 3 other leads from the same person as an after thought which were all perfect.. as they are only pennies it is worth ordering one or two spare for redundancy purposes. I decided to order 3 as backups more in case i broke one and the person stopped selling them etc etc
These leads will allow you to connect the htc to any other source including external speakers which didnt work when putting them in normally but did work when i used this cable in conjunction with it.
this cable is a trrs to trs jack plug and is used to convert a 4 pin socket to a 3 pin socket jack plug.

I've been using a pair of JVC Gummy Air on my Desire since I got it, not a single problem.

Re: TRRS Pinouts for Desire
I've used some headphones, and 2 different aux connector for the cars and all 3 work absolutely perfectly. No issues at all.
Sent from my HTC Desire

I have been using my Yuin PK3 earbuds for music since I got my Desire and it has been working without any problems.

Oh yeah and I've also hooked it into the tv via a standard audio cable!

Not sure what you guys are talking about but my AIAIAI headset works fine with the Desire

[Q] Need AUX + mic cable

Hey guys, I have my old Orbit 2 (Polaris) car mount in my car for use with my ne DHD (which is an absolute perfect, tight, unobtrusive fit btw!). I have a usb charging cable and phono-to-phono cable hooked up behind my dash to allow for charging and audio through my car stereo. Thing is the calls arent great for the other caller (I have to put on loudspeaker for the caller to hear me speak), possibly due to sensitivity of the DHD mic.
Anyway, I was wondering does anyone know where I might get a good long AUX + mic cable such as the one that comes with this car holder ... http://www.griffintechnology.com/products/windowseat-handsfree
I want to see if this will have a better mic sensitivity and pick up my voice better while driving.

You need something like this:
http://www.kvconnection.com/product-p/009-243.htm
The price on this one is a rip-off but that's basicaly what you need to get it running. Plug it in the phone, then plug the cable you already have installed in the headphones output and you need to buy a good quality microphone, plug it in the other female connector and then install it in your car so it can pick up your voice.
Or if you don't use your stock headphones and you are good with the soldering gun, you can buy two female 3.5mm stereo connectors, cut the headphones cable and make the y-cable yourself. Or even use the headphone's microphone and install just one female jack, connected to the headphones' cables. You can try if the headphones' mic will work - just plug them in, point the microphone to yourself where you intend to install it, start the engine and call someone.

[Q] Question on microphine/audio output

I have been researching online about using car aux-in cable for making phone calls.
I heard that some phones work and some do not. In those cases, when it doesn't work, it means that the person in the phone cannot hear what you say, because by default the mic is muted when something is plugged in to the jack.
With HTC Sensation, does this happen? Is the phone mic muted when a headset/aux cable is plugged in to the phone? If yes, is there any workaround? What is the general solution to make phone calls via aux cable?
I heard that some people might use the griffin cable with mic, but since my aux port is located where the shifter is, I am not sure how the quality would be. Any idea?
Thanks

well, i hope this answers ur question
i have made calls/received calls via aux (when im listening to music in da car n get a phone call i dont uplug it, just answer)
i talk thru the mic normally and i hear the other person from tha car speakers.
so i guess the mic is not muted

From previous experience - though not with Sensation, as I'm all blue-tooth now, the following was true
If you plug in a normal 3.5mm TRS jack (stereo headphone / line-in / etc) the phone detects it as headphones and not headset, so the device realised there was no "in-line" mic, and used the phone's microphone itself.
A better option (which I did) was to fashion my own lead - using another HTC headset, but removing the two earphones, and soldering the cables to an in-line socket. This worked well, because I had a microphone clipped to me, with remote control for music (don't want to touch the phone when driving now, do we!!) and the stereo audio feed back to the car speakers. Cost me about £3 in total, including the second headset.
I would imagine this to be the same for the Sensation too, as all these sockets have various detection mechanisms, to make the right things happen, depending on what you connect.
Good luck, and safe driving!
