I don't know if you guys have noticed, but the audio through the headphone jack has massive noise. Its maddening when listening to music quietly. Worst I've ever heard on a portable device, although the audio quality is pretty decent. What we need to fix this is control over the headphone amplifier (voodoo sound offers this on other devices fingers crossed) to lower the level and reduce noise. SO my question is, does anyone know how to lower the headphone amplifier volume with a hack? We can also use this thread to beg supercurio to support our usa versions with voodoo sound
On a related note, if anyone wants to list what eq program they use that could be interesting. They all suck in my opinion. The one CM uses is pretty good, so I'm looking forward to that.
Edit: here is the answer to the problem. Lower the app volume using this https://play.google.com/store/apps/details?id=com.teamkang.fauxsound
I was going to retire my nexus S with voodoo(and get the SG3-have the 32 GB pre order) until the info came out about the difference between the US version and International in regards to audio. Disturbing to learn about the hiss. The US version has basically the same hardware, audio wise as the HTC Evo LTE. Certainly nothing to brag about unless anyone has info to the contrary. Waiting for voodoo may be a long time.
My nexus S is absolutely quiet between tracks, no hiss, pops.

I know I had the nexus s too. I'm not exaggerating about the hiss. The amp is way too high. I think I'll see a significant improvement with reduced amp volume. Just need to figure out how.
HOXL isn't great in this area either.

I would love it if this could be fixed. Its driving me ocd!
I installed AwesomeBeats and use my Beats Solo headphones and dont have that problem... not sure if my setup makes any difference though because i never use OEM headphones

Indeed, I have the same problem on my unit and attribute it to the analog gain that is too high. I'm also looking for a way to turn down the headphone amplifier. Note that I also have an HTC One XL which uses the same audio hardware. On that phone, the amplifier isn't turned up as much (overall volume is lower), and the hiss is lower, though still perceptible.
However, I've found a thread with info that suggests that not all GS3 units exhibit this problem.
http://forums.androidcentral.com/sa...sign-fault-audio-buzz-hiss-crackle-noise.html
Therefore I'm really curious: does anyone not hear noise/hiss at low volume levels?
Note that you will only hear the noise with ear buds or low-impedance headphones. Bigger headphones aren't sensitive enough.
I do not hear the noise you speak of on any of my headphones or earbuds.
I tried the stock music player and Power Amp. Power Amp is my main choice of listening to music. I also tried different EQ settings. Nothing.
i dont hear the hiss through my headphones but when I have it hooked up in my car through AUX, i get the hiss =/
Listen to a song that is very quiet, with lower impedance headphones (16 ohms). Classical music or music with areas that are bit more quiet will exhibit this. Also if you listen close, you can even hear the hiss/white noise when you push a capacitive button for a few seconds until they stop the lighting effect.
I think this problem exists on all phones, just some people cant hear it and some listen to their music at louder volumes. I have tested this across a few roms and players, it shows up on everything. I believe it is the amplifier inside this thing being cranked too loud as well.

By chance, do you have the phone plugged in when you get the hiss? And does the hiss only appear when nothing is playing? If it's plugged in to the car charger, try unplugging it and seeing if the hiss goes away. My phone makes all sorts of noise through aux when nothing is playing (like between podcasts or if I'm searching for a song). I noticed that if I unplug the charger, all the noise goes away.

people who say there's no hiss either have earbuds that rest outside the ear, or are deaf/dumb. There are no units that don't have the problem. If there is I'll eat my hat. We need to find a way to lower the analogue headphone volume. Supercurio is the only person capable, to my knowledge. He doesn't seem thrilled to try the US model. I feel like starting a bounty or something.

Well I'm sorry to disappoint you, but I have a pair of Ultimate Ears $1,500 In Ear Monitors, and when listening to Flac, or streaming from Google Music, there is absolutely no noise more than any other phone. Listening to Jazz, Classical, Soul for the most part. Actually aside from iPhone (doesn't do Flac), my Verizon SGS3 performs much better (In the noise, and balance department) than any of my previous Android phones: Verizon or GSM Galaxy Nexus, HTC Rezound, AT&T's HTC One X to name a few.
HTC's One X actually blew up my right bass driver on my UE18's because of the retarded "Beats" moniker crappy EQ which I was very pissed about, and no one should be using EVER with a pair of good headphones... good thing I ended up getting IEM rebuilt for free by peeps at Ultimate Ears.
Moral of the story, you shouldn't be throwing the assumptions, you haven't tried the entire inventory of SGS3...

Been through 3 different android devices and countless headphones and I know exactly what you mean. This background noise is simply unbearable. Some people either don't mind or listen to volumes high enough to drown out the hiss. Personally, it is driving me nuts and I've tried everything I could to solve this problem and came to 2 solutions that will help you out.
1. Jack up phone's volume to max and use a passive dual potentiometer to lower volume back to desired level effectively lowering the background noise as well. At loud volumes the SNR is great so turning volume to max and then lowering it with an external device will lower the both the volume of music AND the background noise to exactly what you want, low volume music with great SNR. The only downside is you'll have to buy/build that external volume control device. I built mine from scratch and it looked something like: http://beavishifi.com/articles/Volume_Control/
2. Get an external DAC to effectively bypass phone's crappy audio DAC altogether. I bought a FiiO E7 external DAC and an OTG cable. SGS3 supports them both right out of the box. Fiio E7 is built around Wolfson WM8740 DAC and the sound quality it produces is simply mind blowing. At night, in a room with everything turned off, using in-ear (canal) headphones with all volumes set lowest and I still have to listen very hard in order to hear the background noise. And of course, the audio is crystal clear as well. If you care about audio quality, this will be the best $71 you'll ever spend.

Hmm you're right. I tested this morning on drive to work and only hear the loud hiss when charging cable is plugged in. Volume is lower though compared to playing from other sources (usb, sd) on my head unit. Seems like I have to up the volume by like +5 to get similar loudness.
I'll test it again with my car dock i have (Infuse 4g dock) and see if its similar. I'll also test with my old Evo and Zune player through AUX to hear hte sound difference.

Thanks for the advice. Not sure it's worth it as I have a cowon j3 with a similar chip in it. What do you think? I like only carrying 1 device and listening to Pandora, that's why I don't usually carry the cowon. I use 1964 ears quads too. The device you made is intriguing.

I believe that will eliminate noise usually caused by unshielded wires and noisy power sources (such as crappy car chargers) but won't improve SGS3 DAC's SNR. I didn't actually experiment with one of those so I'm just speculating.
When a sound in a certain frequency appears on my phone it comes with an annoying hissing sound especially on the left channel. it drives be bananas! i already sent it back and got a replacement and the bug is still there. Work arounds that didn't work for me: switching to ATR, Another audio cable, Sound About(my headphones is also detected as actual headphones), making a call.
I'm desperate for a solution. I hope it gets fixed with lollipop but if not i rely on you guys.
I already posted this on reddit and i keep you guys updated if i get a valuable answer.
i would really appreciate it if you got anything to help me out with.

It's not about sensitivity, it's about impedance. Headphones with a low impedance always have this problem on the G3.
Unfortunately there is nothing you can do, except for using other headphones or soldering a resistor in row to your headphones, but that would ruin the HiFi-capabilities of the M50X.
In my experience, Headphones with 20+ Ohms work well, but it seems that the M50X (which have 38 Ohms) don't have a very linear impedance.
I've talked to LG about that issue, but their support doesn't know anything about anything. After a long discussion about it not being a defect, she just said that she will forward the complain to their engineers...
You're not the only one though
damn this is too bad. i hope it can be fixed with a software update unfortunately i can say that the support indeed is pretty bad at least from my point of view they doesn't seem to have any IT experience.

It can't be fixed via software. It's a hardware issue.
I think a headphone amplifier unit should 'correct' the issue assuming my understanding of wikipedia is incorrect
Output Impedance
Many headphone amplifiers have an output impedance in the range of 0.5 - 50 Ohms. The 1996 IEC 61938 standard recommended an output impedance of 120 Ohms, but in practice this is rarely used and not recommended with modern headphones. High output impedance can result in frequency response fluctuations, due to varying load impedance at different frequencies. In 2008 Stereophile Magazine published an article that showed that a 120-Ohm output impedance could cause a 5-dB error in frequency response with certain types of headphones. However, the author of the article also states: ″The ramifications for subjective assessment of headphones are more troublesome because it is usually unclear what assumptions the manufacturer has made regarding source impedance. ″ [2]
More importantly, low output impedance can reduce distortion by improving the control that the source has over the transducer. This is often expressed as damping factor, with higher damping factors greatly reducing distortion.[3] One company shows a 45 dB improvement in THD+N at 30 Hz for their low-impedance amplifier compared to a 30-ohm amplifier.[4] For example, a 32 Ω headphone driven by a headphone amp with a <1 Ω output impedance would have a damping factor of >32, whereas the same headphone driven with an iPod Touch 3G (7 Ω output impedance) [5] would have a damping factor of just 4.6. If the 120 ohms recommendation is applied, the damping factor would be an unacceptably low 0.26 and consequently distortion would be significantly higher. Conversely, the same iPod Touch driving a pair of 120 ohm headphones would have a respectable damping factor of 17.1, and would most likely not benefit from the addition of a lower impedance headphone amplifier.
In addition to output impedance, other specifications are relevant to choosing a headphone amplifier — THD, frequency response, IMD, output power, minimum load impedance, and other measurements are also significant. However, most of these will be improved by lowering output impedance and hence improving damping factor.

That's right, a dedicated headphone amplifier would fix this, because the input impedance is typically very high.
But most heaphone amps in the lower price range decrease sound quality significantly.
The problem I'm facing..
There is noise+distortion+hissing during call but ignore-able
And when headphones are connected I cant understand or listen to any thing I only hear wired noises..
Any fix guys ?
Dont know if its technical or software based issue
if technical then I bet it could be faulty ic chips

I sent my G3 to service center and today they gave me a new replacement phone, that one had indeed technical problem and the main board replacement wasn't available :highfive:
Hello, I am very much kind of headphone lover guy.
Recently, I bought Beyerdynamic DT770 Pro 32Ohm (32Ohm version for portable users).
But the sound is not coming to its best. I plugged the same headphone to iPhone and it's working awesome. iPhone quality is same as it work on macbook and PC.
So, I was worried, is my headphone supportable on my Nexus 5 or I just have to invest in buying mp3 player.
I will provide link, where you all cann see the specifications and tell if that is supported on this device or not, because I am not that much of technical guy.
Headphone Link - http://north-america.beyerdynamic.com/shop/dt-770-pro-32-ohm.html
I have rooted my phone and is currently running on ElementX kernel and Chroma ROM.
Hope you guys can help me.
Thank you.
Is it quality that's bad or volume level? Or a bit of both?
Sent from my Nexus 5 using Tapatalk
More of a volume. The quality is good.
Try this - https://play.google.com/store/apps/details?id=com.n5rvb.nexus5realvolumebooster
Also i always use poweramp with the preset set on rock. Always find it the best sounding
Sent from my Nexus 5 using Tapatalk
Install any kernel management app, like kernel adiutor, and in sound menu raise headphone gain.
So I just did what you said. I already have paid version poweramp and installed volume booster, set it to 19 and 95 for headphone and speaker. Set my present to rock, but I was just little curious, are you also facing a little distortion in the sound or just me? Because I think, I can listen the distortion, maybe because these are kind of Audiophile headphones, so they are giving deep detail of every sound.
As far the volume matters, its 2.00AM, so very much silence environment but I can definitely feel the volume is increased.
How much did I set the headphone gain too?
I already installed the volume booster app, should I also gain on this app too?
Try these!!!!!
These are the "loudest" and best in-ear buds you can get!!!! http://amzn.com/B00WI79EK0 They are Zorloo "Z:ero". Forget about booster apps, eq apps, etc... This thing has a inline "DAC" it plugs into the "USB" port and not the 3.5mm jack. Read up on it!!! I have wasted money on many in the ear, over the ear, everything under the sun to get the best sound and these are my latest find. (Thanks to an article about the Nokia 808 and how people are pimping them out). I cant say enough how LOUD!!!!!!!!!! they are.
YOU WONT BE DISAPPOINTED!!!!
I think they are lurking under the radar because its not a "Brand" name like Shure, Whitestone, or any of the "high" end stuff people are used to paying 100's of dollars for. But the technology using "DAC" has been around and if your looking for something to drive your "over the ear" stuff maybe a usb cable micro to mini adapter and then a USB DAC Stick might work for you... I am sure you can also try to "hack" the "Z:ero" by cutting off the "ear buds" and then going to the local "radio shack" and getting a 3.5mm stereo input jack and soldering the four wires to it and you just made yourself a custom low cost "DAC"...
Just a quick review I google...
http://www.soundguys.com/zero-digital-earphones-review-5997/
Try them!!!
Install viper for android. It helps with the sound processing on the N5 immensely.
I was going to say something about the impedance, but my headphones are a higher impedance than that 35ohm, and I'm pleased with the quality and volume. I know you are not looking for just volume, you are looking for volume and quality. Something I found in the past with some of the Android EQ settings (didn't matter which app) some of the settings like bass boost, would actually lower the volume coming to my headset.
A good set of headphones shouldn't have to have any EQ settings changed at all, leaving it on flat should be the best, and for preference, you can always use flat as a reference.
Every headphones is different from others: if you want a boost in volume/quality, you should try an amplifier like FiiO E6 (http://www.amazon.it/FiiO-E6-Amplif...6?ie=UTF8&qid=1439893840&sr=8-6&keywords=fiio )
32 ohm is a bit high for a smartphone, so there is a possibility that Nexus can't handle that well.
I have a pair of 32 ohm dt770 as well as 32ohm mmx300 Beyerdynamic. They both work fine.
They definitely shine with a good headphone amp, but if you're running without one straight to a phone or laptop, definitely get 32 ohm. It's the lowest they make for mobile type uses.
Hey team,
Has anyone else noticed how terrible the on board DAC is? It is the loudest piece of audio equipment I have ever heard. Just noticed it and can't unnotice it. When I swapped back to my 4th Gen ipod touch it sounded utterly incredible in comparison. I'm getting noise, strange squealing in both ears at around 5000hz when music is playing? Any fix for this one? I read a few posts and edited the mixer.xml file but it just crapped out all sound. Definitely not my headphones or an impedance issue, I have tried with multiple headphones.
I'm running Fulmics 6.1.
The sound of the G3 DAC also lacks a whole ton of power, even when compared to other cell phones. Not sure whats going on there, the clarity of the mids and highs are rather compromised. I even occasionally hear bass distorting on some tracks (it's not the tracks or the headphones).

I use to think the same but with a unusual trick everything seems fine now.
If ur headphones have a detachable cable plug first the cable to the jack without the headphones n in the status bar u will see a cable icon instead of the headphone one, now connect the headphones to the other end of the cable, I know is unusual but sounds change terrific.
If u don't have a detachable headphones the next is plugin ur headphones, make a call, u need answered to the other side (I make call to my cellphone company ) detach the headphones n reconnect again during the call (remember u have to be answered) n now u can end the call. Again the noise n hiss sounds go away after this, but u Need to do this Everytime u reboot the phone.

Okay, that sounds a bit strange, but I will give it a go. If it works, I might make a Tasker profile, so that it happens immediately. Surely this is a software problem right? Are you running marshmallow or what?
Gave it a try but there is still the problem. It only really happens after playing a track or during music playing, there is quite a lot of white noise in the signal behind the music too. Not terrible, but it is very prominent when comparing to better sources.
Not sure what the problem is but I'm going to try a different fix.
Suggest me a good in-ear earphones under $100 with high impedance. I want to get rid of this horrible hissing noise.
This has nothing to do with impedance. I have in-ear headphones with 16 Ohm impedance (JBL T110) and there's noise as well. But I have on-ear headphones (Connect IT CI-235) and there's no noise at all. The issue is how much voltage can the headphones take. So I would recommend you to get some on-ear ones and if they're above 20 dollars they should do the job.

Actually I do have 16ohm impedance earphone. Sony EX-15AP. Hissing is very much audible.
It's really weird, I have never heard this hissing.
I even just tried a pair of free ones I was given free on a sightseeing bus, quality is rubbish but still no hissing, I get a crackle if I twist the jack but that's it.
Problem is combination of low impedance and high sensitivity - which is pretty much case for majority of IEMs. Bigger headphones are often less sensitive so they do not tend to have the hissing issue. For 100usd, I would suggest buying any headphones you like + iEMatch impedance adapter (https://ifi-audio.com/portfolio-view/accessory-iematch/) - particularly if you need mic/buttons.
Edit: per iEmatch manual, mic/buttons on headphones will be disconnected by this adapter, so better verify with Ifi company before purchase.
Budget version would be ChiFi headphones (KZ, Senfer, ..) + cheap impedance adapter, but beware that this combination doesn't allow usage of cable with mic/buttons. I am quite happy with the budget solution..
Just flash the hissing noise fix and you can use any earphones

What's that? There was one "fix" flying around few months ago, but it did absolutely nothing (modified some parameters in mixer path xml file with no effect whatsoever). I would love to have something which actually works..

That's actually what the "fix" does. It's a hardware issue so no soft fix

There's a magisk module you can flash here in the forums. Om My phone it removes almost all hissing :good:

Link please? I saw and tried only one and that was useless - I even tried to decrease the headphones gain in the xml file by ~99% and it didn't do anything.

I'm using the nougat version on flyme os. But I've tried om stock Oreo too and it removes almost all hissing for me. Go for the magisk version and be sure to get the right version.

Unfortunately I hear absolutely no difference in the hissing or overal volume of headphones. I'd say it's only a placebo "fix".. On the other hand, decreasing the headphones gain via custom kernel masks the hissing quite effectively - hissing is still the same, but as you have to turn up the volume, Signal To Noise ratio increases as well and you can't hear the noise over music. Quiet songs/passages are still bad though.

Thank you for the advice but imho, on-ear headphones are not that mobile.

iam using ATH-M50X everywhere
But Otherwise i cant use In Ear with gum and so iam on the way to build my own In Ear Monitors :fingers-crossed:

I got interested on this. I looked for some cheap ones but there is something i dont get, there are 30, 70 or 150 ohms so i wonder which one i have to pick. And some of those even say that they dont work on mobile phones so... I get even more confused.
And want to know if you found some cheap ones with the mic/buttons function

I guess it only changes the gain or amplifiction. But my piston 3 almost gets no hiss with that fix. Super noisy without.

70 ohm should be fine, it will remove pretty much all the hissing and keeps overal volume high enough. Or there is an even cheaper and more versatile alternative - cable with analogue volume control (https://www.ebay.com/itm/131489435905). By turning the volume down, you effectively increase the impedance and hissing disappears. And you can fine tune it to each headphone. Though still no mic/button control.. I have similar one with button and mic on the cable and it makes wonders, but I purchased it years ago and can't find it anymore. Try to look for one in your favorite shops, you might have more luck.

No idea what it does, on my phone nothing audible. From the description it should do what custom kernel with sound control does - only mask hissing.
Just get a pair of Apple EarPods. They have an impedance of around 40-45 ohms and work great.
