HTC EVO External Mic

I was wondering if anyone has tried any external Microphones (connected to the Headphone jack) on the HTC EVO to get better sound quality on Video recording? I have found a few external microphones that I was thinking about trying but before investing in that, thought I would ask the group. Below are some links to some Microphones I thought about trying. As I cannot add links yet I have broken it up below.

Thank you for your assistance.

Uuuhh...it's a headphone jack, not a microphone jack. In other words, output not input. Where's my face palm pic at?

Oh jeez, you should find that pic and take a real good look at it.

Evo External MIC
So it is not set up for wired headsets which would have a MIC. I would think that this would be standard in all phones for people that don't want bluetooth....

Wired Headset
According to this site there is 3.5mm wired headsets for the EVO.

Yes it does, sombdy just wanted to try and be a jackass to someone to make his day better.

It is set up for wired mic headset, don't know if when recording video if it would use that input or not, worth trying though.

Thank you for the response. I knew the answer about the headset just was being facetious, and the next post was to prove it. I was just wondering if anyone has tried it yet.
I know there has been a few breakdowns of the EVO, Has anyone come up with the wireing schematic for the EVO yet, to see what type of jack it is and what Pins are actually connected to that jack?
Thanks again.

It can take a standard headphone OR headphone/mic combo. Maybe a DIY super microphone? Use the standard headphone/mic cable and add a amplified omni directional mic?

I use a wired headphone/mic combo that I got with an old blackberry and the mic works fine on that

I believe RadioShack has splitters that will let you plug a regular mic into the headset jack.

RCA adapter for atrix?

Does anyone know of a working solution for a USB to RCA output on the atrix? I have AV inputs in my car and want to, mirror my phone onto my nav screen. Did a sear h and didn't find anything. DINC has a custom cable for this from HTC. THANKS!

You'd most likely need a digital to analog converter (like those boxes), and you'd need a bunch more since I doubt it has any video out besides the HDMI. Which doesn't do any sort of mirroring without hacks (unless I am not aware?)
That said, I don't think it is possible.

That's pretty much the answer all my searching has led me too as well. Samsung , HTC, and apple all support video out through USB or even audio jack.

Atrix has an hdmi port so there would be no need for video over usb. Analog audio can be transferred over, however.

[Q] Audio line-out for Galaxy Nexus

Hello all ,
Is there a way to get an audio line-out from the Galaxy Nexus, either using an adapter or a docking station? I'm not looking for a solution like the one offered by the Samsung Galaxy S2's car dock (which streams bluetooth audio from the phone to the dock, then the dock turns the bluetooth streaming to analog audio through a 3.5mm port) but rather something like an adapter for the MHL port or from the docking station.
Appreciate all the help!

The obvious solution (at least to me) is to plug into the headphone jack. You could also use either the media dock or MHL adapter in conjunction with an HDMI-to-analog adapter such as the one linked below:

He's asking for a line out solution because it will bypass the internal headphone amp that is utilized when the 3.5mm port is used. If you're plugging the phone into speakers or a sound system that way you'll get much better sound.

If the mhl -> HDMI cable adapter carries both audio and video, you could use an hdmi breakout adapter to split the digital audio. It depends on the HDMI output capabilities of the phone and the acceptability of digital audio for your needs.
Edit: would no doubt be a cumbersome solution. It all comes down to your usage scenario for the output.

Thank you vespoid, ardabey.
What OJ in Compton said, I'm looking to bypass the internal headphone amp, not sure if there are any details on the car dock or desk dock, I hope 3rd party manufacturers come up with something, any solutions are welcome.

Never thought about this, but a contactless dock with HDMI out directly to the AMP = audio bliss. Thanks to the forum for letting me see the obvious

Bumping this thread...has anyone successfully done this? I want line out audio for my car's 3.5mm AUX input - had it with my ipod and it sounded much better than through the headphone jack, as well the convenience of not having to maintain two volumes.
Hoping the official car dock that uses the 3 pin connector and has a 3.5 out would do this, but I'm worried it will just use BT to transmit the audio to the dock like I read the Nexus One dock did.

I wish too that the NG had line level out.
I think it's a limitation of the hardware. I think Apple is the online one that really uses line level out via it's dock connector.
I hope someday Google will use some sort of line level out on their reference hardware or built support directly into a newer OS.
I remember my old Dell DJ had line level out. Soooooo much better.

There is nothing wrong with the 3.5mm output sound quality wise.
Trying to drive headphone-like impedance (lower) with a line out isn't the best idea, but driving higher impedance inputs like your car deck isn't that bad as long as you let the amps do the "work" of boosting the volume and not your phone. While not optimal, the decrease in sound quality shouldn't be very noticeable.
The main advantage of the digital audio though USB (what apple does) IMO is that it eliminates the need to have both the USB plugged in to charge and the 3.5 mm cord for audio. It also allows song data to be shared and device control from the speaker/head unit. Good setups will recognize most android devices as mass USB storage and provide the same functionality, but I'm not sure how the MTS on the GN will affect this.

I would wait and see how the audio quality is from the dock. Even if it is bluetooth, the audio quality may not be that bad.

The problem is, that if the head unit supports MTP then yes it can read the device like mass-storage, thats fine, but it doesn't allow you to stream media from radio apps, youtube and turn-by-turn directions from gps, this is what we are looking for...
technically it's not sending analog audio output through the USB, its just reading the stored media on the phone.
I have read that samsung phones are able to accomplish sending analog audio through the USB while charging, with the correct resistance values (adapter) or possibly with software pointing the audio in that direction (for example code build into the framework/API)
this is one major thing that Android lacks over iPhone, this problem should be addressed ASAP. I'm hoping CM9 might be able to find a solution for this.

I agree, i hope they fix this soon toi. It would make the development of accessories much easier for all android phones. Seems like a no brainer but I guess Google has other priorities...

Just starred this, if the hardware is able to do that I find it completely stupid that they do not allow it.
Smartphones audio amps are not exactly famous for being top-quality so having this possibility would be great.

Thanks. The lack of this feature is ridiculous/mind-boggling/suprising.

Well, if you were waiting for the card dock to solve your problems... it doesn't. Plugging into the dock's "line out" gets you amp driven sound. I really do not understand why this is such an issue for Android. When I plug somoething into my 3 year old Nokia smartphone a window pops up for me to choose headphones, headset or line out. Why can't ICS offer the option and if in the car dock, default to line out? A USB solution is not going to help if you are using the car dock.

Which if I understand correctly uses Bluetooth to transmit compressed audio from the phone to the dock, then delivers it through the 3.5mm jack. Why not just have a digital signal go through the USB port!?

actually the pogo pin transfers the digitial audio and the dock decodes it into analog to the 3.5mm output

MLH Adapter Audio Out

OK I just got my MLH adapter and everything works fine but the sound. I have no sound at all =/ because im outputting to a monitor that has no speakers I use external speakers. I tried plugging my headphones in my phone to see if I'd get sound but I can't is there any work around @ all?

oh that dosen't sound good
Sorry for the bad pun, but could not help myself. Your problem is that hdmi outputs video and sound through one connection or is bundled together. The phone probably will not output sound from the head phone jack, but good thinking. Maybe someone with more experience with the OS will have the know-how to rig it to work with your set-up. Well I hope you the best in your connection mishap. Jahman

External Microphone for Video recording.

I searched through the forums and found some posts that said in order to use your external Mic you need a Y adapter. And that it doesn't support stereo, and some other issues.
Can someone link me to a Y adapter that would work along with a good value microphone that I can use during video recording on my Galaxy S III?
I'm surprised that a company hasn't made a product for this yet where you just plug it in and it works. The camera and video quality are great, but the sound is lacking greatly.

You can also get an OTG cable then you can use the yeti and have digital hd stereo

would it work while recording a video?

If I find a mic with a 3.5mm jack can't I just plug it in? the ear buds that come with the phone have a microphone where the volume controls are and it picks up sound during video recording.

the headphone jack can only output a limited amount of power to drive a mic device, any non mobile mic is not going work. if you want high quality sound you must do so with the usb using either an external usb soundcard with analog 3.5mm inputs or just a usb mic like the yeti which is the best you can really get. and yes s3 has native support for almost any kind of usb device so it will work like if you plug in usbdevices to your desktop/laptop as long as it is Plug and play compatible. whether there are good apps for these usage scenarios though is another story.
oh and you are welcome...

Good info, thanks. Looked up the yeti mic you mentioned, but it's kinda pricey at $109 and not exactly portable either. Do you use it?
(EDIT: too bad most jack mics suck)

I was looking at these earlier and thought about getting the edutige http://www.amazon.com/gp/product/B004XC6KHS/ref=ox_sc_act_title_2?ie=UTF8&smid=ATVPDKIKX0DER. A few of the reviews mention it working with a couple of android phones. Only issue is it seems to pick up alot of background noise. If anyone decides to get this for their s3 please tell us how it performs.

Not really sure what you want a dedicated microphone for taking videos on a cell phone. If you are looking to make quality videos, you might as well get a decent external microphone and syncing up audio in post production. I know my brother uses this in conjunction with a 60D. Will probably sound a lot better than the $30 options posted above. http://www.amazon.com/Zoom-H1-Portable-Digital-Recorder/dp/B003QKBVYK/ref=pd_cp_MI_0

I want to record videos with decent sound quality at concerts, etc.. I don't want distorted bass and good audio picture. Recommend me ext. microphone for my SGS3, thanks!
