Hello guys,
I tested apple earpods on my HTC DHD. For the music portion, they sound pretty good, the control buttons works fine but thats no good if i cant even take a call. The microphone does not work and the person on the other end of a call hears a high pitched whine.
Is it possible to use the phone's microphone when the earpods is plugged in?

One can get a 3.5mm 4 poles audio stereo male to female extension cable then cut the cable in the half and interchange the Ground / MIC wire connections with soldering iron.

I've got a problem when I plug my HTC Titan into my car stereo as well as cigarette adapter.
I'm also got a kind of custom setup using the HTC Y Adapter with a 2.5mm jack and MiniUSB jack
Audio
Honda Civic Stock Stereo -> CD Changer to Aux Input Adapter -> 3.5mm to 2.5mm adapter -> 2.5mm input on HTC Y adapter.
Power
Belkin Cig. Lighter to USB Female Port (From old iPaq) -> HTC Stock Sync/Charge USB cable -> MiniUSB input on HTC Y adapter.
So, when both the power and audio are plugged in, I hear a horrible hiss on my car stereo, not to mention a sound that varies in pitch to my throttle. When I unplug the power, the audio is completely clean. To me this seems like some kind of a grounding issue - to say that the Audio and Power both have seperate grounds, and bridging the two creates a potential difference in the form of noise on my Sound. Also to note: I only hear the noise when the Y adapter is plugged into the phone. With the audio and power plugged into the Y adapter, but the Y adapter not plugged into the phone, It's perfectly clean. I'm kind of baffeled.
The only solution I can think of is to gut the Belkin Power->USB adapter, and providing it from 12VDC elsewhere. I've got a tap directly below my passenger seat where I have a big power inverter tied to my battery. I don't know if I'd hear the same sound by grabbing my power from there.
Anyone with an engineering mindset have an idea? I'm open to suggestions.
You are right, you have a problem with ground.
I have the same problem with a mp3 player. When I plug the audio + power I have noise, just audio is fine.
You may try the inverter as it would probably filter the noise you're getting from the DC power in your car.
you just nead an in car ground loop isolator used for getting rid of noise on the low level signal to amplifiers.They are just a 1:1 audio transformer
Any incar hifi shop or ebay will have plenty.
I have the same problem, with a polaris using standard headphones. I'm thinking the polaris itself has issues dealing with audio+charging
i had the same problem with an ipod charger, sent the car to the wreckers, and woot, problem solved sorry that was no help
Usually happens when the signal wires (mm adapters + input cord) aren't shielded and pick up the magnetic field from the ground resulting in the engine noise. Sometimes, making sure the signal wires are not touching the power cord and keeping them separated might help. I'm not really sure, since I'm a 100% noob too all this. Let me know what your fix is. I'm not too hip on all the car audio stuff anymore, but if you wanna put some hydraulics in your ride, then I can definitely help you out.
more likely the problem is in the phone, so ...
2.5 headset
I have an o2 XDA Atom Exec and got an o2 in-ear stereo headset with it.
That headset is now faulty, one side no longer works and i cant determine where the problem is.
Anyways, i want an in-ear headphones to use with the pda mainly to listen to audio rather than to make calls.
I tried connecting it with 3.5mm headphones with an adapter but with any movement of the adapter, the pda would automatically stop the audio and load dial the first number on the dialed list. Its very annoying.
I tried both the small stick type adapter and the wire adapter with the same result.
So now i'm after an in-ear stereo 2.5mm headset or a solution to stop it from going to the phone mode.
Any help ?
Thanks
is it work fine be4?
perhaps There is some short circuit in your headphone itself or maybe in jack port. trying use another headphone to identify the problem
oftenly headphone for mobile has 4 intersection in its jack. and common music headphone only have 3 intersection, I think use the 3 intersection jack should be fine
you can use the nokia 2.5mm headsets. they are like the OEM ones but they sound better. they both use the 3 ring jack, instead of the more standard 2 ring jack.
Hi!
I have this for some time: http://www.amazon.com/gp/product/B0...&pf_rd_t=101&pf_rd_p=470938811&pf_rd_i=507846
(Actually, I baught it in a store so I'm not sure it's excatly the same but it looks the same)
Recently, I baught this one:
http://www.amazon.co.uk/Headphone-HTC-VIVA-exclusive-Duragadget/dp/B001LIM8F0/ref=pd_rhf_p_t_2
When I plug the old one in my HTC Touch Cruise and then stereo headphones, to it's 3.5mm jack (without microphone), I can use phone's mic and plugged headphones to talk.
When I do the same with new one I can't use phone's mic. I can hear the other side through headphones but I can't be heard.
What might be a reason for this?
And can I fix this problem somehow so I don't have to unplug headphones each time I want to talk if I'm listening to the music?
Thank you very much in advance!
P.S. FM Radio works with both adapters.
there is no std for 3.5mm mini-jack with mic included
the org spc is only audio out
some headset makers add another ring which don't interfere with the
left, right and ground connectors
but there is no std they can follow
thumb rule is if mic is not mentioned in relation with the 3.5mm adaptor
mic is not supported as they use the pure audio out mini-jack std
thumb rule 2 is if mic is mentioned but it's not the same manufactures
in both end they may not implement mic in 3.5mm the same way and it will
only work with audio out
Thank you for your quick answer but I'm not sure you understood me.
I do not use external mic.
In first case I use 3in1 adapter and my stereo headphone with 3.5mm connector without microphone.
In second case I use this simple in-line adapter and same headphones.
In first case, during call, I can hear the other side through headphones, and the other side hears me through built-in-phone microphone.
In second case, during call, I can hear the other side through headphones, but other side can't hear me.
In both cases FM radio works well. I mention this because I saw that mic and FM antenna are on the same pin in USBext (if that's important since I don't use external mic)
about fm then all it needs is an antenna connected to to it
any stereo maybe even mono connected with a wire will do
heck you can cut off the airplugs from a cable and use it for fm
normaly when one connects a headset speaker and mic on the device itself
are muted
even if it's a headset without mic so cool that your fist case works at all
This first one adapter is original HTC. It has 2.5mm, 3.5mm, USBext for data and charging and USBext for headset connectors. And unfortunately it is too big for any other use except in car (to connect to car's audio aux input) or at home (to connect to home AV reciever).
So I baught this cheap simple in-line adapter. And it is suprisingly well built. And it works great as stereo adapter. Only problem is that it turns of microphone.
Anyhow I did some additional testing.
I tried SE Xperia X1 since it has built in 3.5mm connector. and it works like this first one. That means microphone works.
I also tried plugging this first adapter into my touch cruise and then plugging this second adapter into it's USBext for headset. The result is the same as if I plug second adapter directly into touch cruise. Microphone doesn't work.
Interesting thing is that in all cases (including Xperia) when I listen to the music with external headphones soudn comes only out of them. But when phone starts ringing sound comes from both headphones and from built-in-phone external speaker.
!!! Maybe the most important thing is that microphone doesn't work even if only second adapter is plugged into the phone, without headphones plugged in it.
Obviously this second non-HTC adapter doesn't work as HTC originally planned that kind of adapter to work and now I need a way to fix this.
It seems to me that this adapter is maybe stereo adapter with mic, but I don't have that kind of headset to try it. And if I had it I'm not sure it would be the right one since there's no standard for them.
As I see it when I plug in adapter phone somehow detects it and changes some registry key which mutes microphone.
Does anybody know what to change in registry so that phone doesn't mute microphone?
Or how can I see what changes in registry when I plug in the adapter?
Do you think if I manage to fix this, will that affect bluetooth headset also?
Thank you very much for any help!
There's the microusb port. Can that support (or does the headphone/mic jack support) connecting an external stero mic to record better quality music than the onboard mono of the mytouch 4g?
I've search around and found some chinese stuff that's iffy, and I don't know if it will work. I'm looking for a solid solution to some real solid stereo recording of acoustic music. I've got a 3.5mm mic that works when plugged into mic jack of my laptop, it worked with an old AIWA "walkman" I had with an external mic jack. The head phone jack of the MT4G is also 3.5mm. ?
Thanks

Hmm, good question. I'm a musician too, that would be sweet for mobile recording.
This might be a bit obvious, but since you've already got a 3.5mm mic, why don't you plug it in and try?

From what I understand, the Mytouch 4G uses a standard microUSB port that only charges/connects the device. Thus, barring some kind of circuitry miracle, the MT4G cannot record audio from the microUSB port.
Unfortunately, the device will only record mono from the 3.5mm input. Even if you did use a stereo mic, I believe that the MT4G will only record from one channel. Like Sunsean suggested, test it out with the mic you have. Sorry to be the bearer of bad news.
five hundred bucks for mono mic in.
sigh.
i'll try but looks like it's a nonstarter.
thanks guys.
When I plug in my headphones to the HTC, it acknowledges that they are plugged in as the headphone symbol shows up but no sound comes when I play a video or a game. These headphones came with the phone too. BUT when I use these same headphones on my iPhone it works perfectly, so I know something is wrong with the HTC, not the headphones. Other headphones also don't work on the HTC. Only the HTC's inbuilt speakers work but no sound from headphones. Do anyone know how to fix this problem?

Could be your headphone jack. It may be possible to replace it yourself, or pay someone to do it for you.
Headphone jack, probably worn out or has crap in it clogging it up. Mine is still working well with headphones but no dice with my car headphone to aux cable. The cable is probably outdated. I have 3rd party headphones that worked well at first but now the microphone is acting up during calls and boomsound "glitches" on and off now and again. Headphones are in good - very good condition but I can't rule out an internal break in the wire.
I would be inclined to say that the m9 has sensitive electronics attached to the headphone jack and any short circuits or voltage/amperage/resistance discrepancies would be picked up to protect the rest of the sound system. Headphone jacks tend to arc too which is why you get a thump in speakers when you connect or disconnect the jack.
