I am trying to adapt an external dynamic microphone for use with my Exhibit 4G (there is no forum section for this phone and I believe it is similar to the Epic 4G). I bought a 3.5mm PRRS plug with three discrete shielded stripped end cables (White=Left Audio, Yellow=Right Audio, Red=Mic), a PRS inline jack, and a female XLR mic connector.
Using the PRRS pinout of P=Left Audio, R1=Right Audio, R2=Ground, and S=Mic, I soldered the shields of White and Yellow to the sleeve of the PRS jack, White to the pin and Yellow to the ring. My stereo headphones work perfectly with this arrangement.
I then soldered the shield of Red to ground of the XLR and Red to audio. I then successfully tested all connections from the PRRS plug to the PRS jack and the XLR connector with an ohmmeter.
When everything is connected, the headphones still work the same but the phone doesn't "hear" the external mic or disable the internal mic like it does with the headset that came with the phone.
What am I doing wrong? Any ideas?
Thanks!
I don't see you getting much help here, but maybe I'm wrong.

I'm trying to modify a broken handsfree set into a headphone adaptor which leaves the builtin mic active, but I have trouble getting the wiring right.
Does anyone know which color wire is which inside the headphone cable?
I checked at http://wiki.xda-developers.com/wiki/Connectors, but I have 6 (!) wires in my cable, and the description only lists 4.
I suspect the two copper wires (one in each cable) are both GND and can be connected toghether. But then, I still have one too much, a green one.
I scraped off some isolation on the wires and twisted them together with the wires from one of the earpieces (i tried both), but however I do I can't get any sound!
I have another headset, so I know the jack is still working.
Does anyone have a clue?
Thanks!
Anyone?
This may help. I removed the ear phones supplied with the XDA and added a female connector. Now I can use any 3.5mm earphone set, and the handsfree mike.
I found the instructions here...

Copper goes to earth, red is right channel and green is left channel for sterio.
Hope this helps
I'm not sure this is the right place or whether something like this has been done before...
I have a WM 6.5.3 device with a 3.5mm headphone/mic jack. It obviously accepts input through that jack and I was wondering if I could somehow connect my mp3 player to my phone using a male - male 3.5mm cable and an app that will play everything that comes through the mic input through the integrated phone speakers? I see that my headphones equipped with a mic have an extra contact, so I would probably just have to cut them open and splice a male 3.5mm connector onto the end that usually has the mic/earbuds.
Hello!
I enabled the aux input of my car radio and wire a cable jacks.
the problem is that when I get a call from my htc hd2, the sound is heard from the speakers but does not work the microphone for conversation because the hd2 course off the microphone of the device active because the headset with microphone.
Is there any way to wire the cable jack (4 pins) and attach a microphone to the cable itself? Some might suggest a scheme electricity?
thanks!
:sorry my bad english
In theory it should work as long as you can get the components and wire the cable correctly. whether or not your mouth would be too far from the microphone might be an issue,
Unfortunately, if I connect the phone jack, hd2 excludes the microphon base to activate the headset that is built, then the conversation can not happen, but I feel he did not hear anything
should understand how the microphone is connected to the headphone series

Depending on where your phone is, you could use a regular 3.5 mm male to male extension going from your radio to the phone. I have mine set up like that and the mic on the phone itself is powerful enough to pick up your voice. I ran a 10ft cable(3.5 mm male to male) from the radio,under the instrument panel, up the side of the door in the molding of the windshield to the sunvisor where my phone is clipped to the visor by the clip on the case. It works fine but you have to adjust the volume between your phone and the radio to find the best combination to avoid major feedback so the caller doesn't hear his own voice echoing in the background. I can't post links yet but if you go to youtube and search "iphone handsfree iphone in car setup" you will see how I did my iphone but I now have the same setup with the Hd2.
Ive been pondering this and thought i'd post it here for your general feedback.
the plug for the hearphone/mic headset that comes with the device is a triple pole 3.5mm jack - same thing used by video camcorders into the phono adaptors.
On the back of my car stereo unit ive an Aux in which would be the red/white plugs of this cable for the audio feed. This is generally how i'd plug my phone in to listen to my music.
Now with the 3rd wite (yellow) i was thinking if i used a small PC Mic (3.5mm jack) and get a patch cable made to connect this to a male phono would this work? it'd also give me the ability to hear my phone throughthe car, and a lengthy cable i can hide and place a mic in the car leaving a simple 3.5mm jack to plug into
Hello...I am excited to get the xoom. One thing that would make my day, and life as a voice dude, would be the ability to plug a USB mic into it and record using an audio program. I understand some cool audio apps are out or about to be out. Has any one tried a blue mic or really any type of USB microphone? Can it even be done?
Thanks
A USB microphone would be very cool, indeed.
I've seen lots of microphones that plug into an iPod's headphone jack, like this one:
http://www.amazon.com/VC-00300-VeriCorder-Mini-Mic/dp/B001Q964QI/
I checked with Vericorder, though, and they said this:
"No, the Motorola Droid headphone jack pinout is different from the Apple style, with the mic and ground connections reversed on the 4 pin TRSS configuration."
I wonder if if the Xoom even has a mic connection on its headphone port?

Yes, the headphone jack does appear to have microphone abilities. I just plugged in a standard wired headset, hit voice search and stuffed the xoom under a pile of heavy blankets. It picked up a fairly complex sentence perfectly.
Not the most scientific test, but a test none the less...
While its not USB, but I suppose you could look at using a regular hard-wired, high end mic with an adapter.
