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!
WTF is the Exhibit? Is it a SGS? Is it on touchwiz? I don't think it is a Sprint phone either....

It is a T-Mobile Samsung Exhibit 4G (SGH-T759).
Its not an epic 4g... this question doesnt belong in this forum... sorry.
Sorry, I would love to help, but I have no idea.

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.
Hey peeps,
Anyone else had issues with lining out to an amp/set of speakers? I can jack in headphones and all is gravy but when I connect a standard 3.5mm jack to my amp I get nothing/nada?! I had an issue with my nexus s sounding crackly and distorted too. If I connect the same cable to the headphone socket of my TV it's fine. What gives?

I've plugged mine into my car without issues. I have it plugged into the RCA input jacks that connect to my back-seat dvd player. So its 3.5mm to red/white rca
So I use an aux cable for audio in my car. I can make calls through the speakers this way. Sometimes though the Mic doesn't work and sometimes it does. Does anyone know if there is something that specially triggers the Mic to work?

Sounds like a loose cable connection. Normally those 3.5mm jacks have 3 or 4 sections on them to support stereo audio plus a mic. If your cable was plugged in and got yanked to the side, it might break some wires in the cable or bend the plug internally (phone or car). But I'm speculating here...got another cable you can try?
Long long.. long ago. I got turtle beach headphones I highly regret getting. The issue is after the speakers caved in I was left with two wires, one that is used to hear in the head phones. Comes with a standard av set attached headphone jack for these turtle beaches and other headphones. Another cord was for the mic.
Now for some time I've been using the av headphone jack cord for surround sound on my ps3 "after hooking it up" then left with a cordless jack. I can attach any headphone inside and I'll get sound. My issue is however I cannot control the volume, it stays on a mid range volume that isn't high or low.
So I was wondering is there an app that can do this by using a duo headset jack plugged into my phone and connecting the jacks? It seems a lot harder than its made to be but it is worth it, if your wondering why I just don't use my headset in the surround sound its because my headphones aren't long enough and the ****ty phones jack plug in I bought is loose on 3.5m headphones.
Is there anything or am I doomed for now?
Edit: here's my example -

I searched around for some better headphones for my galaxy S3 (GT-I9300), to unleash the full music experience the phone got. As I prefer a more powerful earphone I feel not as comfortable with the sound of the original ones, but I don’t wanted to lose the comfort of the Samsung Headset - Microphone and Remote control.
As you can see here, I changed the original Samsung headset cable to a pair of Sennheiser Headphones. In case you are interested in doing the same here is what I Did.
What i used:
A Pair of Samsung Headset Headphones, in my Case Samsung Galaxy S3 (GT-I9300)
A Pair of Headphones, as shown in the Pictures a Sennheiser CX 300-II
A Solder Station, a bit of soldering wire
A Tool called third Hand, or another little vice
Fine Pliers and a little slot screw driver
A Voltmeter
Just to ensure. I am not responsible for any injuries, damages and defects on the headphones, your mobile, other components or your health. The following hints worked for me and my equipment, yours may be different.
If you aren’t use in Voltmeter testing’s, soldering and fine mechanical works you shouldn’t do this.
First I dismounted the silicone Ear Adapters from all headphones. Then I used the pliers to demount the Samsung headphones. In My case I grabbed the stick where the Ear Adapter was on and ripped it off. I have no further use for them, so I broke its housing.
Inside the Cables are mounted on the speaker. I used the solder station, to liquefy the soldered cable connection from the speaker.
In next step I opened the cable knot and got the cable out of the Samsung housing.
Openig the Sennheiser Headphones:
I used my fingernails to get of the silver ring of the housing, maybe also a guitar plektron will do the same. In my case it worked when I turned it around while pressing my nails in.
Please see Picture 1
With the little slot screw driver I opened up the in key and slot position of the housing.
Please see Picture 2 and 3
I also used the solder station, to liquefy the soldered cable connection from the speaker.
I noted myself on which connection which colour of wire was. On the back side of the Sennheiser Speaker there was a red sign on one of the contacts.
I opened the knot and pulled out the cable. Then I inserted the white Samsung cable in the rubber bumper. I think its important to make sure inserting the right side of the Samsung cable into the right side of the new Earphone. To ensure better gliding I used a little of my wives hand cream on the cable.
When mounted the cable in the headphone, I fastened it again with a knot. I had to be carful, the cable isn’t as strong as it seems.
This is the pin configuration I measured on my headphones. As I heard that there is more than one pin configurations in different countries, please ensure what’s yours. So the wire connection I made may differ to the one which is the correct in your case.
Please see Picture 4
Soldering, I made,
Please see Picture 5
Right Headphone:
In my case I attached the red wire of the Samsung headset cable on the Sennheiser headphone at the solder position where the red dot was.
Left Headphone:
I attached the green wire of the Samsung headset cable on the Sennheiser headphone at the solder position where the red dot was.
Please see Picture 6
Reassembling should be no problem then.
Have fun with your modified headphones.
Please see Picture 7

I think the originals are ok but, I'm am a bit of ambitious in music, the original samsungs speaker don't have such powerful bass and not so clear highs. So they don't give a good picture of what a great sound experience the Phone itselve provides.
If you buy a original Headset at Amazon its about 5€, the Senheiser are 35€. There might be the difference from .
Greetings
Awesome
I don't understand though why you used the samsung cord couldn't you have just bought headphones from amazon that had their own cord? Or did you have to have the samsung cord because of the plug to match the microphone? Thanks
