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.

Car Dock disassembly - adding a LINE OUT

So I got my car dock, I knew it didn't come with a line out, but figured I could add one. You all know how aewsome it would be to have a line out jack on this thing rather than the stock "speakers". Well good news, I am going to make myself a line out and will post pictures about how I am doing it.
I have the thing taken apart right now, and just need to go buy a 3.5mm audio jack.
So, my plan will be to still use the cardock for phone and stereo profiles, just using my car stereo's aux in rather than the dock's weak speakers. I'll leave the microphones on the dock intact, just not the speakers. The good news is the speakers are removable, making room for a 3.5mm audio jack. the bad news? the jack will have to be on the dock body, not base. I'm sure if you try hard enough, one of yoiu will find a place in the base for a jack, but for now, I'm going to add one to the body, on the bottom (in portrait mode).
There you have it, I'll be able to make the dock a semi-permanent fixture in my car and never have to plug in an audio cable to get my music through my car speakers.
Pictures to follow soon, I just couldn't wait to start this project, and get some reactions / moral support.

Someone else looked at doing the same thing a while back. I seem to recall they came up against several hurdles. It is not as clear cut as it seems.
On the face of it- it would seem the approach you are taking will necessitate you having your car stereo ON and AUX selected any time you need to take a phone call. Might be a bit of a pain when you are for example, listening to the car radio and your phone rings. Or if the phone rings and your stereo happens to be turned off.
I find the inbuilt speakers totally adequate for Phone Audio. This arrangement has the benefit it being standalone and means N1 Phone Audio works regardless of current car stereo state. I send the Media Audio to my car stereo via BT though, as it sure benefits from the better speakers quality and auto pauses the Media when the phone is in use.
Good luck with it and do a search for the other thread as there is some good info info in there.
PS take a look through this thread http://forum.xda-developers.com/showthread.php?p=6427057&postcount=39
Might save you some heart ache

I only found that thread, after i had my dock quite disassembled and did a google search for the chipset under the RF shield. :/
I don't use my car's head unit for anything but aux audio, radio is dead to me, so I shouldn't have any problems. The hurdle is the audio being fed to the speakers do NOT share a common ground. They utilize an active-balanced system. both leads are hot, common to themselves.
Now it seems as I will have to choose which channel gets full audio and just bum 'common' from the dominant channel. or i come up with some way to convert two independent balanced audio feeds to a common ground.
I have had no luck looking up the NF2301 daughter board. I was hoping to find a schematic detailing the line level outputs, but no go. I did think it was interesting that the car dock and desktop dock share the same PCB, too bad there is no detailed schematic yet...

FAILURE - giving up
So, after creatively placing some resistors and whatnot, I got a decent line level with common ground, that won't blow up the built-in amp. However, as pointed out in that other thread, there is some BS DSP that notches the lower frequencies out of the signal to the speakers. I got it all setup in my car, plugged in to my aux-out, and it sounded like i was using the voice profile. I took the aux cable and plugged into my headphone jack on the phone, and all the bass came through just fine.
So, for now? The audio out on the car dock is meant for the crappy on-board speakers. not real ones. Sad...
Now, it seems the only way to get an aux out of the cardock would be to swap the board with a desktop dock, and cut a hole for the aux jack, or just do some more soldering to not modify the casing of the cardock.
Too bad, I had it working, but the damn DSP chip/amp puts out ****ty audio quality

Alternatively, at the point you have a desktop dock.... Instead of butchering it for the board, Just install it somewhere out of site in your car and connect it to your cars Aux-in with a 3.5mm lead. Thats what I have done. Works well. Only downside is I still have to manually connect the desktop. It does not autoconnect to deskdock when N1 is placed in cardock obviously.
Too bad your set up did not work for now.

Maybe it's using a low bitrate A2DP bluetooth transfer. Either way, bluetooth will be lower quality than a direct plug.

I believe this is the likely reason why Google didn't include an audio out port on the dock. Yes, it's on the desktop dock, but that's really all the desktop dock handles, whereas the car dock has a mic as well, etc.

I would be interested in detailed disassembly instructions if you wouldn't mind.

detail isn't really necessary, it's pretty straightforward.
-get a knife and use it to peel off the black rectangular sticker on the front of the dock. it's right where the battery on the phone is when it's docked.
-undo the 4 screws behind the sticker
-pop the two halves of the phone-holder part of the dock apart. if you can't get them apart with a bit of pulling get your thumb nail or a knife in between the two halves.
that's about as far as you need to go to get to the useful bits.

Thanks! I'll see if I can figure anything out.

I had this same idea when I first got my car dock, but I couldn't convince myself to hack my new dock. Instead I hacked an old stereo Bluetooth headset with the same mod and it works perfectly.

Don't ignore this post...
Ok So I took a dive in to it. I disassembled my dock (yes even after reading all that I could find on the internet, including this thread), but in disbelief I wanted to find out for my self. I soldered a head phone jack to the speaker wires, and thought I had something good when connected to my computer speakers. (it worked and I was surprised). But after hooking it all up in the car and actually hearing the quality, I was sorrily disappointed.
Major failure, the sound is terrible. Not tolerable at all. Comparable to scratching fingernails across a chalk board and trying to listen to some good tunes at the same time from an FM radio with very poor reception.
Heed my warning, do not attempt to mod the dock for an FM out, it will not work.

Issues with head phone jack

So I have had issues with the head phone jack on two different thunderbolts.
When I plug in the head phones if the plug turns clockwise or counter clockwise at certain points I will lose sound from the left head phone. Same thing happens if you gently push the plug to the right.
I also tested headphones on the models verizon has on display and it did it on those too.
(note, I tried 3 different sets of head phones). This is really bothersome to me because if its in your pocket sometimes the plug gets nudged or turned).
Anyone else experience this? Not sure if I should attempt to exchange yet again.

Mine was working fine for a while but then my left side of ear buds went out. But then I plugged my ear buds into my PC. Turns out the Ear buds went bad. Skullcandy breaks way too easy...Phone is Fine though. just Coincidence I guess.

I discovered this same exact problem the other day and here's what I've found. I have 2 sets of headphones, 1 works perfectly fine and the other exhibits this same problem with the left ear going out. For the bad set, if I have them plugged in all the way then I have the problem, but if I pull it up a tiny bit after I've plugged them in it works fine. I don't know if there is a tiny difference in the length of the connectors or what but they just don't work when plugged in all the way. I figure I'll goto the hardware store and find a tiny little bushing and just put it on the headphone connector so it doesn't plug in all the way.

I also posted on the androidforums about this. Apparently it seems fairly common. I have exchanged my phone once for this issue and the new one came back the same way. I dont know if its a bad batch of phones or what. Even some of the display models did it at the store so it seems like a crap shoot.
The best thing to do would be call verizon support at this point I think and let them know its an issue so it becomes a known issue with them. They told me today that they haven't heard anything about this incident.

Same issue here. I noticed it when i had it plugged into my aux cable in my truck. Also, I don't know if its related but playing pandora over my speakers results in a really high pitched "click" from time to time. I never experience it when just my headphones are plugged in nor when i am using winamp.

I also have this problem - also the left speaker that gets cut out. I can either try to force the jack further in, pull it out a bit, or move it around until the connection is made. These are with UE TripleFi 10's.

I have the same problem.

So verizon sent me a new phone and it does not have the issue the other two phones exhibited. It seems there are a bad batch of these headphone jacks. I suggest calling Verizon and letting them know that you are having an issue if its bothering you, so they at least recognize that there are quite a few people having the issue.

If the Thunderbolt's headphone jack is anything like my other smartphones, the reason you're having problems with your headphones is because you're not using the proper kind. Look at the picture on
http://www.appleinsider.com/articles/09/02/12/macbook_owners_frustrated_by_new_audio_jacks.html
Regular earphones have 3 metal bands separated by two nonmetal strips, whereas headphones for phones oftentimes have 4 metal bands separated by three nonmetal strips. This means if you're using a three-banded headphone into a four-banded jack, the contacts don't properly align.
The reason for this is simple: the headphone jack also serves as a jack for a microphone/earpiece.
I have a special set of stereo headphones that also have a microphone so if I'm listening to music and get a call, I can answer without having to unplug.
Hope that helps.

This is not the issue as the new phone has no problem with my 3 banded head phones work just great now. There is a defect in some of the inputs. And most high quality head phones such as etymonics and shures do not have the 4 banded design.
The description you mentioned does not support the anomaly that is happening, sound does not travel through one headphone nothing gets re routed the speakers on the actual phone.
Although this is very useful post it does not explain why the head phones now work perfectly as they did on some of the other TB's at the verizon store.
I also have post on android forums about this matter.

no issue with it here

This is going to sound like an odd solution and I may catch some flack for it but here it goes: Go to the auto parts store and buy spark plug Jelly. It has the unique quality of being able to transfer electric current hence no more losing audio L or R. I did this on my D1 and it worked perfectly. Just a tip; don't use a ton less is more.

While that would help the connection, I can't say I would ever recommend it. It's going to be a dust collector, and nearly impossible to clean out. It is better suited on the spark plug because the plug is covered and sealed for most of its life.
Also, it can make a short between two of the connections, spark plugs only have one connection where the jelly goes.

Ok those are good points. What I do know from experience is that it did work on my D1 and I never seemed to have an issue with dust but that might have been because the case I used plugged the headphone jack. So.... I will repeal my suggestion; don't use spark plug jelly.

this post is wrong. im having the issues and ive been using headphones with a mic and music controls since day 1. the issue is with the jack, not with the type of headphones being used. ive tried 5 different sets of headphones and they all exhibit the same issue.

I agree with you, it should have nothing to do with having a mic, as the same exact pair of head phones I used ( 3 ring) that did not work on the older phone now work perfectly on the new phone.

Why some headphones don't work with some phones?

Hello.
I'm trying to figure out and possible find a solution for why some headphones don't work with some phones?
For example a very well known brand Scullcandy. Their line of Skullcandy FIX Bud headphones work fine with Galaxy S2, but don't work with Galaxy S3, they also don't work with LG Nitro HD.
On GS3 they work for media playback, but when trying dial out or answer a call, the phone totally disconnects the headphones, the icon that shows when headphones are plugged in is no longer showed and at that point one has to physically re-plug the headphones in order to use them for media playback.
It does sound like phone's software issue, I sure hope so and there is a way fix it...
Another phone I had bad experience was LG Nitro HD. Even though the phone is totally waste of money it don't accept any iphone type headphones, they might work for playback, but mic or buttons don't work.
So what could possibly causing this issues?
I've tried post on phone related sections, but got no answers...
I also tried contact Samsung support regarding this issue, but they simply blew me off with "we don't provide support for 3nd hardware". Now I'm waiting for an answer from Skullcandy support.
Any ideas?
Thank you.

Probably the 3-pin layout of your phone. some are really weird in the way they work
x10man

There might be a couple reasons. The first is the connector. Some headsets use a three pole connector while others use a four pole connector. The other issue will likely be he pin out. The headphone jack might be a standard mechanical interface but not electrically. Both are hard problems but an adapter cable might help you.

All headphones connectors in question are 4 pin type, without using micrometer they look identical. Since all these headphones works fine in mp3 players, where only 3 pin connectors used, means the 3 out of 4 pins are in proper places and connected properly inside the wire.
So, without taking headphones apart it seems physically there is nothing different between them.
In addition, if there would be something physically wrong, it would not explain, why SGS3 sense when Skullcandy headphones connected, it shows headphones icon, but when a phone call initialized it "forgets" about it.
It sure seem to me like software related..

Finally fixed bluetooth in the car while using the AUX IN jack

Tonight I made my first accessory purchase at the local Verizon store... as their prices have always been pretty bad, but I have a military discount of 15%, so I bit the bullet and purchased an iBolt cradle system. If you haven't seen it, there is a review in the accessory section, it's pretty spot on, but this important update is for those of us who don't have A2DP streaming in the car, and are forced to use the AUX IN jack.
Long story short, when using this dock, you have the option of sending the sound thru your micro USB port or out the phones speaker in back. This dock comes with a nine foot long cable that has micro USB at one end, and regular USB and a 3.5mm audio jack at the other. This beautiful setup allows you to not touch the evil headphone jack (trump card) on the phone, but rather it lets you the phone play music out the USB connection while retaining Bluetooth phone connectivity thru your cars Bluetooth connection! (while charging)
Silly that I had to buy a $32 device to get functionality that the AT&T version of our phone has natively... but at least it's fixed!

Not trying to be a jerk or anything, but what is the advantage of playing music through the USB instead of bluetooth? I actually like the BT option - plays music but pauses when a call come in and lowers the volume for GPS directions. Works great all at the same time...

There's a large portion of G3 owners who do not have bluetooth streaming (A2DP). Just because you have bluetooth phone connectivity does not mean you have bluetooth streaming. We are forced to use the aux in jack in the car to listen to music. I think a large portion of S3 owners simply tried to use the headphones jack on the phone... But if you do that, you cannot use bluetooth. Every sound is routed thru the headphones jack. You cannot toggle this.
So, using the iBolt cradle, witch ports the sound out via usb instead of the headphones jack, I am able to retain my cars bluetooth functionality.
Side note, not sure if you know this, but the sound quality of bluetooth streamed music is pretty bad compared to a cabled connection.

We are forced to use the aux in jack in the car to listen to music. I think a large portion of S3 owners simply tried to use the headphones jack on the phone... But if you do that, you cannot use bluetooth. Every sound is routed thru the headphones jack. You cannot toggle this.
So, using the iBolt cradle, witch ports the sound out via usb instead of the headphones jack, I am able to retain my cars bluetooth functionality.
Side note, not sure if you know this, but the sound quality of bluetooth streamed music is pretty bad compared to a cabled connection.

I'd recommend this if you don't have BT streaming: http://www.monoprice.com/products/p...=10827&cs_id=1082704&p_id=9472&seq=1&format=2
That combined with a USB car charger to keep it charged at all times would maybe be a nice way to solve your issue for ~$30
Note: I don't own the product, but the reviews are good and it seems it would just be nice to have.

A day after I purchased the iBolt I received this little gadget in the mail from ebay.
USB Bluetooth Adapter
For under $10 it gives you the same A2DP bluetooth audio streaming. But, the difference is it doesn't sound nearly as good for the lower end of the spectrum. But, in a pinch it's awesome, and for the price, you can't beat it. I have it as a backup for now.
I took about 30 min and hid the iBolt cabling today. I like the fact that I moved the cradle to the top left of the windshield, away from the center console. Will post some pics later today of the install.

I am surprised at how easy the phone is to use with my left hand, from the steering wheel. Retaining the bluetooth functionality, specificallly my integrated microphone, really makes this work around worth every penny. Hope it helps someone else!

Oh well now I understand. Thanks for clarifying. Of course I didn't mean any offense.

No worries, none taken. I am just ecstatic to be playing music via S3 thru my car stereo and still be able to use the cars bluetooth for phone calls! Now if we could come up with a fix for this damn NO SIM error, I would be in heaven. LOL!

Can you post the dock and where you got it?

The OP mentioned they bought it from the Verizon store and that it was discussed in the Accessories thread:

Sweet, I was contemplating a bluetooth to 3.5mm for my car because of this issue, but this might be a better solution. Looks like we might have the same exact setup soon including the mini cooper :good:

I-bolt rocks. Bought one the other day. Search for best price. Down in the low to mid $30 range now depending on shipping and coupons.

Could anybody solve my problem? My car doesn't have a usb port so I cant use the iBolt to play music through it. I use the cassette player to audio jack and use bluetooth talk through my car speakers. Is there a solution to use bluetooth while using the audio jack?

Yes. I don't know why I didn't think of this sooner, but on anther board, someone brought this up and it works, albeit ghetto'ish.
Mount the phone somewhere in the car where you can speak towards the mic. Plug the cassette tape adapter into the headphones jack. When a call comes in, just answer the phone keeping the headphone jack in use, and the sound will come thru your stereo, but the mic you will be using is the one on the phone. Talked to multiple people who all heard me just fine. (even with the mic pointed downwards!)

The cable is exactly the right length to mount the ibolt anywhere in the car, hell I think we could mount it on the rear window, lol! There is space behind the base of the center console where you can tuck away any extra cable you have before you route the cable to the jacks. I decided to use an add on 2.1a USB car charger (cig lighter adapter) vs the cars internal USB as I don't think the MINI USB pumps out anything more than 450 mA (1\4 what the adapter puts out I bought seperately)

Does that require a custom Recovery and/or ROM, perhaps? I'd like to keep things relatively stock for now, though am OK with tweaks. Plus, the iBolt looks convenient to use in my car.

So how do you know if you have bluetooth streaming? aren't all the G3's the same in that respect? Or is it up to what your car can do?

Yes and unlcked bootloader

I know I can do that but I want to use the bluetooth in my car to make calls(my car doesn't have bluetooth audio only calls). When I use the headphone jack to make calls people say their voice echoes back but if I use the cars bluetooth its fine.
