What's the deal with the headphone jack?

It seems the world and his dog are conspiring to prevent me enjoying music from my M500, to say nothing of the AD2P ferrago.
OK, so my M500 didn't come with any sort of handsfree kit, mono or otherwise. The goons at the local Orange shop tell me it only comes with a mono earpiece anyway, so no real loss there. I grabbed a cheap adaptor from a local shop, and it works, so long as you don't mind taking the phone out your pocket and whipping out the cable when a call comes in.
Turns out I do mind, so I set about looking for an adaptor with a mic... and find one! Only... it only pipes sound to the left ear! Indeed, all the adaptors I have tried, bring-your-own-headphones or otherwise, will only give me sound in the left ear. What the hell? I was in The Link today and the manager there said he had the same trouble with his Universal (only he has an official headset that works).
At first I thought maybe I'd damaged it somehow, and since there was some other stuff wrong with it I arranged for a replacement from Orange. No joy, this fresh unit behaves just the same. It really seems the only way to get stereo out of it is with a 3-core adaptor. Say it ain't so?
3 cores good:

4 cores bad:
I mean, are HTC wiring the 2.5mm jack differently to everybody else? Or did Orange mess up the case such that the 4-core plug doesn't sit quite in line?
I did get one off expansys, now that I think about it, that I think worked in both ears, but it had horrible speakers and was pretty uncomfortable. Besides, I took it apart to try and attach the plug to my old HPM-70, which sort of worked but, you guessed it, I couldn't get it to play sound in the right ear!
[edit] Whoops, wrong forum! I guess this belongs in accessories rather than upgrading. Perhaps a friendly mod could move it?

Hi Bobgorila,
I received a stereo headset with my TMO device & it works perfectly for all phine functions including adjusting the volume. Downside is the audio quality is horrible. So I switched to a mono BT earpiece for the phone & a decent stereo headphone with conversion jack for music.
Guess ther must be something wrong with your wiring.

My HTC Charmer gives me stereo sound with on `4 core` adapter, with mic, which I got from eBay, picture attached.
My unit came with a handfree headset, which is `4 core` and gives stereo sound as well, which is why I'm reluctant to get a `3 core` adapter.

Do you have a link for the one from Ebay?
had a look around but they don't look as "substantial"

Don't worry, found it
thanks

At the mall
My phone came with a 3 core stereo headset which I lost. I bought another 3 core sterio headset designed to work with the Palm Treo 650 which worked fine. I didn't need to hunt online, I just bought it at a cell phone accessory shop at my local mall. The Treo 650 is a very popular handset where I am in Canada and heasets are readily available.

I brought a ghetto 2.5-3.5 jack for $3.50 at a common hardware store.
Works with full sound on both channels on my O2 Mini, with a 3rd party 3.5" earphones that came from an el-cheapo Gemini Card Reader/MP3 player.
Looks rather oversized and gaudy, tho.
Remember that HTC sells only the spec and blueprints. OEMs are free to do whatever they want to the original design (called 'rebranding'). Orange may very well have rewired the thing....

headphone jack
I had problems with this. I noticed that on the 3-pole 2.5 to 3.5mm stereo adapter I got from Maplins the poles don't line up exactly with poles on my original headset. The HTC connector doesn't just have an extra pole for the microphone but each pole is a slightly different width. Using this adapter one channel was shorted unless I pulled the connector out slightly.
Sorry if that doesn't make sense, I will try and post a picture.
I did manage to find a source for 4-pole 2.5mm jack plugs in the UK, I bought a set of Koss earplugs and replace the original connector.

Just get a sonyericsson P900 stereo earpiece, it works wonder. sound quality is very good.

[Q] Working headphone adapters

i have the akg k370 whcih dont work with my SGS, since the order of the pins is differend (mic and ground are switched).
since i love that headset im looking for a working adaptor
i couldnt find any in the internet
so far i managed to solder my own from an old adapter which didnt use its microphone pin.
but since it looks...lets say...selfcrafted im looking for one that works that u dont have to cut open and change the pins your self (or add a wire as i did)
if u know of any working ones which use all 4 pins and switch ground and mic pls tell me where i can buy em...

Similar issue here. I have Dr. Dre Beats and from what I've found from reading through is that I need to switch the ground/mic wires? I can do this if necessary and can even get a nice job done of it, but wouldn't this break my headset for other phones/players?
Point being a nice adapter would be sweet.

I bought this one, http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=290460258359&ssPageName=STRK:MEWNX:IT
Still waiting it gets here.

Surely if the ground connection was different then no standard plugs/phones would work or does the phone dynamically change the ouputs on pins depending on what's plugged in (since it has to support tv out as well)?

got the same ones, they work fine.

those adaptors and the nokia ones work, but they make the cable too long besides considering that the headsets mentioned already has a mic and you add another adaptor mith a mic, its simpler to just have an adaptor that switches the mic and ground terminals around
so what i did is i made this

i took my nokia ad-57 adaptor, cut the wire, cannibalized a female 3.5mm 4pole from some generic adaptor, soldered the wire so that ground from the 3.5male is soldered to the second ring from tip. thus, simply, the female of the adaptor is wired like an iphone compatible, and the male is wired galaxy s compatible.
if you cant be bothered to diy, you can get this http://www.kvconnection.com/product-p/km-354r3m-r2f.htm
but at 18$ plus shipping, i just think it is too expensive, lol

damn, that's expensive. but I guess it'll be worth it to make my "expensive" headphones work, lol.

i found one on DX, comes with MIC so you can asnwer the phone and listen without taking out the headphones
waiting for it to arrive and test to see if it's compatible with SGS

I had to stick black tape around my mic button on the headphones I used to use on my iPhone, I kept the same headphones cause they were amazing sound and pricey and didn't want to chuck them away, Didn't realize it would be a problem lol, I want one of these adapters from a Uk store

Ordered an adapter from KVConnection, works like a charm! I think it's worth the price, considering I didn't have the time/tools/parts to make this by myself.

You can say that the adapter is good, perfect,excellent,nice,ok,etc but not worth at all 17$ for wires is pure stealing

I got a blackberry headset from my local street market. The earphones that came with it sound horrible, and the mic is a bit soft. There is no need to change anything however and the button works.
I'm planning on using it with the aux in of my car radio. With computer speakers it seemed to work (no echo). And it works well with a headphone.

[Q] Headset with music control

Hi, I just bought this great phone, and now want to buy headphones with remote control for music and microphone to answer calls ... Juts like the ones the come included with the phone, but with much better sound. Can you recommend some?
Any headphones with remote control, such as the iPhone, would work in the Desire HD with full funcionality? Thank you very much everybody.

Forget that... sorry.

Had a look for some but didn't find. So I'm thinking about making my own by cutting the stock headphone just above the control/mic unit and then attaching to a decent pair of headphones to it. Should be pretty simple I think.

iPhone headsets may work with limited functionality. The Klipsch s4i mic and answer button works but music controls do not.

Instead of attaching headphones attach a 3.5mm jack.

this is the best works perfect, and has a high definition sound
http://www.p4c.philips.com/cgi-bin/dcbint/cpindex.pl?ctn=SHB9000/97&scy=in&slg=en

I personally use the 'jabra bt3030'. Search it on google. The sound quality is awesome and it also is usefull for awnsering calls (great microphone! people don't hear I'm in my car, and my car makes some sound!), but the primary use is for listening to music. I currently have poweramp on my phone and it works with the headset buttons.
The best thing for me is that you can put the phone in your pocket, bag, or leave it on the table and walk away without fear cables getting stuck, or having to stop the music.
What it isn't good for, is navigation. The headset goes in standby when there isn't any sound played. This saves energy but there is a small lag between the headset going on and playing sound. This doesn't happen when listening music or awnsering calls, it stays on. But for navigation, often two words fall away. The battery life is awesome. I sometimes question myself if this thing has a corereactor inside producing it's own energy.
Only negative point is the price. It's more expensive then none bluetooth headsets. But the durability is high and makes up for the price.

I think the Jabra seems the best choice, especially since you can attach your own headphones... The only downside I find is that you must have the bluetooth on all the time, and if the Desire HD battery may suffer because of it. And we all know battery is not one of the strong points in this phone...
Any wired alternative?

Currently I have the Dr. Dre beat Tour mobile headphones. The button works with droidshuffle app. But if the action is more than a single tap of the button, it goes into phone mode. Hoping for someone to fix that. For now I can only use the button as a next track button, but the sound quality is great so i deal with it.

Bluetooth headsets are compatible with almost all phones.
I'd recommend a bluetooth headset but with some tweaks the HTC DHD headset is also great.
You could cut out the earpieces and attach some new ones.

Well looks like cutting and attaching a 3.5mm jack isn't as easy as I thought it would be, I have the sound working but not the controls - I haven't touched anything on that side so I've got no idea why!
Here's what the inside front looks like:

On the second pic, the connection on the top is my new wiring.
For anyone else thinking of having a go, apart from the controls not working, you show be aware that the wires are coated in an enamel which makes the connections a little trickier plus the board is held in with some tough insulating glue which will have to be removed before you can take it out (this might be visible on one side of the first pic - yellowish colour).
Looks like I'll have to keep looking for un-ear headphones with music control and Mic unless anyone has any tips.

Tried to give it a go myself a while ago. I ended up tearing up the wires on the board. The weld spots loosens easily then everything goes to shät.
I like akg headphones. Good quality sound at a reasonable price. At their site they have a model with a remote and mic on it (wired). It only says compatible with iphone.
Does anyone know if they work on other phones, like htc?

Hey how do you connect a bluetooth headset to the Desire HD? I have trouble

wouldnt it be easier just to swap the speer part of the HTC headset
This is what I did..too bad I didn't have a camera lying around to take a pics when i opened up this.But this way you wont ruin your board soldering. Oh and remember to use a 15W-25W (I use an ANTEX C15) or you'll end up burning the speaker coils and the film.
I use Jabra 3030 for music and when I'm driving.This was just an experiment,got this cheap Panasonic headset for a tenner from HMV and sounds amazing..just like my Jabra

hi kamranh3 what is the model of your bt headset? there should be a pairing button somewhere.(read the manual if you're not sure) usually you gotta press it for 2-5 secs to put it on pairing mode.then tap scan for devices on your DHD and it should see your headset..well probably

Sent from my Desire HD using XDA App

@ Rajnus:
the Sennheiser MM50 has "only" a button for take and end calls or can you skip the tracks and adjust the volume?
I haven't found at the moment a heaset fitting for the DHD which has all this features, so I will solder my own headset, since I modifed my HTC RC C160 to have after the mic and control piece a standard 3,5mm female jack to plug each headset. but this solution locks not perfect, there are than to much cables and I can't adjust the volume.
So I will make a second headset: (the parts should arrive in the next days)
a further HTC RC C160 + Sennheiser CX280 (with integrated small Volume controller. all from Amazon.de for less the 40€
I will again open the mic piece of the c160 and solder the cutted wire from the cx280 (after the volume controller) and have so a (for me) perfect DHD headset. let's see if that work
Anyway, if somebody has a better out of the box solution for a in-ear headset with volume and musicplayer control for the DHD please feel free to share!

[Q] High Quality FM Transmitters?

I commute for my new job, so I'm rockin' the wife's Jetta, which doesn't have XM like my truck does.
Anyone have a recommendation of a good FM transmitter for the G2x? Wired or Bluetooth would be fine, as long as I can also charge my phone while using it.
Thanks,

Do you have a cassette player in that car? In my experience, the sound quality is a lot more reliable from the old cassette adapters like this adapter from Walmart

I have a duel radio in my car that connect with Bluetooth and has a ubs in the front that I use to charge my phone. It cost around $160. (With HD radio and CD player). I use a cheep air vent car mount for easy use.

I ended up grabbing a Griffin iTrip. Works OK, and requires no tearing into the dash. I've done that before (wired my first XM unit), but I don't want to do it in the wife's car.

I bought one from Amazon over a year ago after reading many reviews. The GTMax Wireless In-Car Bluetooth FM Transmitter is the best one I have ever had. It's $50 and worth every penny. It has a good quality flexible stalk that plugs in to the lighter socket. It works without distortion thru a bluetooth connection in my car. There's 3.5mm input and output jacks and a usb charging port. It can amplify the signal to increase volume. The antenna broke off of the roof of my car and the reception is still perfect, the FM transmitter is very stong.

I picked up the same thing from buy.com for $35. Just came in the mail today - so far, I'm impressed.

I got the GTMax BT transmitter, and it made me return the iTrip. It works great!

based on the pictures, they both look like they are from GTMax... just one doesn't have the micro USB cables come with it. The output charging amerpage is decent at 1 amp. The dock and fm transmitter is a bonus and seems like you can't go wrong at this price. Based on reviews, it seems decent enough.
I trust XDA input over anything else though
Anyone on here have experience with these GTMax fm transmitters? Or could anyone somehow confirm they are both from GTMax?

TF700 Friction fits in dash of 99-04 Jeep Grand Cherokee, need to make a dock, PICS!

So I discovered this while I had the stereo removed because it ate a cd that I wanted back, it quite literally friction fits into the opening left behind when you remove the stereo and dash bezel around it.

so since this fits, and since the cheapest way for me to get a non-european charger for this thing is to just buy another keyboard dock, I'll take this one i have now with all the strange german keys and gut it for all my connections.
my question is, is there any way to get audio out of this thing without using the 3.5mm jack on the side? I could just make the mount float it but I like how it looks recessed into the dash like that. looks like it belongs there.
so now, interfacing USB with all kinds of fun stuff inside the vehicle yes? 12v power supply? any other ideas of useful apps/accessories for this dockable hi-res car pc?

That's pretty kool!

The stand alone cradle shows a 3.5mm audio out. If you could figure out the wiring you could set up a 12 volt charger and 3.5mm out through the main port. Another option would be using a bluetooth adapter with your stereo.

bluetooth audio still sounds like garbage. I have nothing more than an amplifier and a 3.5mm input in the Jeep now (use it with my phone or my tablet) and since I live in the ghetto, it already looks like someone stole my stereo so it's the perfect anti-theft solution!
what is this "stand alone cradle" you speak of? where do I find this? does anyone have a pinout for the asus proprietary connector?
I kinda want to gut the keyboard and just solder a 3.5 directly to the connector, I want to utilize the SD card reader and USB header on the dock plus a few of the hard buttons will get linked to my steering wheel buttons (track +/-, volume +/- power on/off and "mode" which will toggle between poweramp and navigation. I don't think the standalone cradle will make this easier.
if the cradle is cost effective and can be had with an american charger, I'd be stoked. my euro charger + adapter keep falling out of the wall! and I wouldn't mind having a cradle if it has HDMI on it, I still want an american keyboard for it though, the german one is strange.
it's a WW sku tablet, not a US sku. I bought it in germany.

I already have bigger stuff in there, but yeah, I just installed one of those on a scooter, they're rad little amps! I've got bi-amped components up front and a 10" sub in the back. It's no SPL competition winner but it sounds freakin AWESOME. i like running off the 3.5 'cause I can plug it into other stuff. I'm trying to figure out what to do with the hole in the dash behind the tablet since I have all the other stuff in the back.
here's some more indash porn (ubuntu unity @ 1920x1200 fullscreen goodness.... F yeah!) I'm actually VNC'ing into a chrooted install on my samsung galaxy s3 over wifi (along with leeching internet access) the tablet responds much better when it's not actually running the linux install
much like the tablet just fits, my galaxy s3 in its otterbox docks right into the dash if I open the ashtray, another perfect friction fit, and I can even push up on the ashtray to hit the power button on the phone. I need a pic of them both docked, but unfortunately they're also the only two cameras I have... #firstworldproblems
you can almost read my e-mail, HAHAHAHA!!!

In my car I have a nice Kenwood deck that syncs with my tablet via Bluetooth. It mounts on a 2 point swivel mount I custom made. My case just flips over the top of a square of plexi glass. Sometimes I don't always use bluetooth . Instead I use a 3.5mm. I have alpine type s components all around powered with that power pack. In the back two alpine type s 12 inch subs with a kicker 1000.1 amp.
When I plug my tablet in via 3.5 headphone jack the bass is not strong at all. I tried volume plus but even with bass boost all the way up it sounds weak and even distorted. Synced with Bluetooth or any other source on my Kenwood head unit the subs hit strong. As soon as I switch to headphone jack the bass drops to all most nothing. This happens to my android phone too (pantech marauder). Any other devices plugged in via headphone jack the bass hits strong like normal. Does this happen to you I cannot seem to find out why this is happening

turn the "bass boost" ALL the way off.
I don't know why, but their "bass boost" sharply cuts EVERYTHING below 80hz and boosts everything in a 24db/octave slope around 150hz.
It's the most ineffective "bass boost" i've ever heard.

Duuuuuuuuuuuuuuude that is awesome! It looks even more kickass with Ubuntu on it! Please drive safely though hahaha. And I like your idea of hooking up the buttons to your steering wheel! That's pretty epic. Please take more pics when you're done with your stuff! :good: :good: :good:

So I discovered this while I had the stereo removed because it ate a cd that I wanted back, it quite literally friction fits into the opening left behind when you remove the stereo and dash bezel around it.
so since this fits, and since the cheapest way for me to get a non-european charger for this thing is to just buy another keyboard dock, I'll take this one i have now with all the strange german keys and gut it for all my connections.
my question is, is there any way to get audio out of this thing without using the 3.5mm jack on the side? I could just make the mount float it but I like how it looks recessed into the dash like that. looks like it belongs there.
so now, interfacing USB with all kinds of fun stuff inside the vehicle yes? 12v power supply? any other ideas of useful apps/accessories for this dockable hi-res car pc?

CheapXJ, I'm working out the installation of an Android tablet into my own WJ Grand Cherokee now. I'm debating between a 10'' model such as what you've used and a 7'' model.
The 10'' model requires significantly less frabrication for an installation, but would likely not see much use outside of the vehicle (Something I plan to do).
The 7" model requires enough fabrication to make me question it, but would get a lot of use outside of the vehicle as well.
How tight is the friction fit? If I were to trim the vents off of the center dash trim piece, would there still be enough friction to hold it?
Can you provide any more pictures?
