Does a normal headphones disable the internal mic?

I just want to know, if you plug in a normal headphones (normal one, without mic, only stereo speakers) to the HD 3.5mm audio jack, does the internal mic in the HD still work?
Can you still answer phone calls without unplugging the headphones?
Does the headphones disable the internal mic?
The reason I ask is because I would like to know if I hook up the HD to the car aux input, will it work without adding an extra external microphone.
Thanks guys for helping answering this questions.

No, the mic works. The phone also rings when the headphones are plugged into it.

That's right. The microphone still work. I've been using wired headset to make calls. If it does't work, it would'nt have been possible to make such phone calls.

Thats nice to hear. But from how far away the microphone catches sounds?. If i use my stereo headphones, will the microphone be boosted, like in the speaker mode, when it can catch the voice even from the table, couple feet away?

It works Great in my car, i put it on myside [beside the GEAR]. but car speakers volume should not be very loud.

Speakerphone when 3.5mm jacked in?

Is there any way to get the speaker phone active when 3.5mm audio jack is connected? I use an FMtransmitter connected to the 3.5mm to get the sound out in my car speakers, works fine with music and tomtom sound... but when i get a phone call i would like to answer with speaker phone preferable with the sound still from my car speakers, but with the phone mic activated.
It seams like the phone mic is deactivated when 3.5mm is connected.

I don't know the answer to that specific question, but...
I have a very similar set up to you (though the 3.5mm jack runs directly to my car stereo), using PocketMusic and TomTom.
The in-built mic is active in this case - If I get an incoming call, or make an outgoing call, the audio out is routed through my car stereo (i.e. I hear the other person over the car speakers). The mic still picks up my voice and I can have a conversion. I'm using a regular 3.5mm->double RCA lead (i.e. there is no mic present on the audio jack).

Microphone detection bug?

So I have a 3.5mm jack in my car that connects to the AUX function in the stereo. I used to use this for handsfree with my previous device. (The microphone being used was the phone's microphone, with the 3.5mm jack outputting callers through the car speakers)
Does anyone know how to get the HD2 to properly recognise that the plug being plugged in doesn't have a microphone? It seems to chop off any voice function because the HD2 thinks I've plugged in a headset with a builtin microphone when this one doesn't have that.. It's just a regular 3.5mm jack.
Perhaps a registry hack? Could this be a hardware limitation?
Thanks for any help!

Handsfree calls using headphone jack + internal microphone

One of the features I miss of my Hero that my Nokia N95-8GB had was the ability to plug in a standard pair of headphones (or 3.5mm audio out cable) and use the built in microphone to make hands free calls.
I use the phone a lot in my car whilst driving to and from work to listen to music and would love for it to recognise the standard cable (which it does - indicated by a pair of headphones rather than the headphones/mic icon used to indicate the presence of the hands-free headphones) and be able to automatically answer inbound calls using the internal microphone.
Is there an app for this kind of thing - I'm guessing it is something that is/can be controlled by software?

have you tried it actually? because i use my ipod headphones quite often and it works as expected, sound from headphones and i hold phone closely to my mouth as its using internal mic.

Really not sure what you are looking for. If you plug the standard HTC headphones in using the jack on the top then you can use of the built in mike they have to answer calls.
Or have I missed something?

I've also done exactly what you're asking with my car. I've had my phone in a car holder w/ an audio cable from the Hero's headphone jack to my car's line in jack. I was able to answer calls just fine, and the person on the other end could hear me. (And it was just a standard stereo audio cable, my car doesn't have any sort of built in mic)

im doing the same thing but people on the other end are complaining about an echo of thir voice. I figure its coming from thier voice being picked up by the internal mic. Anybody have any ideas? how can i cut the internal mic while theyare talking. would a cheap wired headset work using its external mic? i could cut the headphones off and splice it into the line in.

I have had my G2 since late September and quickly found out by accident that it does use the internal mic when a headphone is plugged in.
Mine is a simple adaptor from the 3.5 mm into the RCA in my car. If I have the volume up too high, it echoes. If I have the volume down low, I can have a perfect handsfree conversation.
With the headphones I have had problems. In the car, I have the phone laying down and the mic side up. If I am holding the phone in my hand, I have no problems. Shirt pocket, ok. Pants pocket, no way.

Google Now in a car

I would like to use the Google Now voice recognition in my car but when I have the auxiliary cable plugged into my headphone jack, the microphone doesn't work. Right now I need to unplug the headphone jack to access the microphone for voice recognition. How can I get Google Now to work when listening to music in my car?

i bought a cheap bluetooth receiver on ebay and use the bluetooth audio allowing the microphone to still work
Bluetooth Receiver
another option is to buy an adapter that splits the microphone off the headphones allowing you to add an external microphone while still sending to your aux in
Headphone adapter with Mic

Well I decided to go with the bluetooth receiver hopefully it works alright
