[Q] LG G3 hissing sound

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.

Does it appear when using the headphones that came with the G3? And which headphones are you using?

i'm using the ath m50x from audio technica. ****ty in ear headphones including the lg earbuds doesn't have this problem since they're not very sensitive.
thanks for your help mate
by the way it works perfectly fine on the s5 and my computer

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

My new Audiophile headphones problem.

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?

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

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.

Any audiophiles can comment about the DAC?

I am not a audiophile, by any means at all.
On multiple occassions I have seen comments about the Moto Z Play DAC and how about it is actually decent to good.
Can anyone confirm or deny this? For curiousity's sake really.

It does the job is all i can say.

AFAIK DAC is part of SoC and Qualcomm always produced good ones.

It is good. See https://forum.xda-developers.com/moto-z-play/themes/music-players-one-standout-dac-to-192k-t3533577
Audiophiles are a group comprising about .1% of male population. Search for Medical Research ~ 2001, male hearing anomaly/acuity

Audio output is pretty average overall. DAC seems to be fairly accurate (it's just Qualcomm's standard offering, not a discreet DAC like the V10/V20 or Axon 7 have), but there's audible interference from the cell radio and other components with sensitive in-ears and output power is unremarkable

I should add
Output is adequate if you use a low impedance, high efficiency bud. The Apple earpod is not as bad as most reviewers pan it to be. I keep it upside-down and fitted tightly in ear canel.
I have even carved out the plastic to let the bass reflex ports pass while tightly fitted (lol we can't messing to improve audio!)

The Apple Earpod is probably a good choice because it's actually not very low impedance for an earphone (it's 45 ohms), but it is fairly sensitive (109 dB), so it's in a nice middle zone. You get a sensitive in-ear that's 32 ohms or even 16 ohms and you will start to hear the noise floor, interference and some distortion on the Z Play's headphone output. It's not bad for a phone by any means, but it's not especially good either.
I used an external DAC with the Z Play for a while (Fiio E18), but even that would pick up some noise from the call radio if I didn't have it in airplane mode (which I couldn't do all the time). I finally had to get a separate audio player to get the sound quality I wanted.

Hmmm
Yes I do not hear any noise with these buds.
Neither do i hear any clipping.
So how is sound at very low impedance in airplane mode without a DAC? What player do you use? Have you tried UAPP without a DAC?

I did try UAPP. It's very listenable in airplane mode, some system noise (processor maybe?) but the cell radio is the biggest culprit so airplane mode helps. Compared to the V10 or the Pioneer XDP-100R (which is the DAP I bought to use at work) it does sound more compressed and congested, instrument separation isn't as good and it's not quite as clean, but the frequency response seems fairly neutral and it's better than most of the previous smartphones I've had (the Oneplus One especially was pretty bad for audio). Without a discrete DAC/amp like the V10 it's as good as I would reasonably expect. It also doesn't have much power, but that wasn't a big deal for me since I only intended to use it with IEMs (usually Cardas A8s).

Does the headphone jack makes hissing/ static noise?

Coming from Lenovo p2 which has similar designs ( both are from lemoto and the headphone jack and antenna seems to be in similar position). Lenovo p2 has this annoying static noise while using in-ear headphone, yes I say in-ear headphone because it won't happen on earbuds, only iems. I guess that's because earbuds have higher impedance? It's extremely audible when playing music at low volume. Anyway back to my original question, does such issue exists on moto z play? I did some Google there seems to be people complaining about this but I want confirmation from you guys. Try listening to some music at low volume using IEM and tell me if there is any hissing noise please. Thanks in advance

Yes it does - more so if you enable the stock equalizer. It is quite obvious if you listen to audio book or speeches in low volume.
Nougat update does have minimized it. Listening to music in low volume is cleaner.
However - the sound signature thro' audio jack is excellent - deep n solid feel to it

No static on any of my IEMs at volume steps 0,1 and 2 playing through Apple Music and PowerAmp.

These are my work arounds:
1. Installed Poweramp app
2. I use Poweramp in-built equalizer
3. I don't use default equalizer while using headphones.
My headphones:
1. audio technica ath-m50x (headphones)
2. shure se 215 (in ear type)
3. jaybird X3 ( blue tooth)
If you root it (I have not rooted this moto) Arise viper4A is an excellent option.
Please note the sound signature and audio output via headphone jack is excellent. It can even drive audio technica ath-m50x, which has heavy drivers with ease. If you don't use the system equalizer, post nougat update the hiss is almost not there.
This phone is an excellent value for money. I am using it for more than 6 month. It has a heft to it but feels solid in-hand. Buttery smooth, insane battery and zero heating (except while charging). I am very happy!

[DISCUSSION] Headphone Jack performance

I wanted to start a thread discussing the performance of the headphone jack. I'm a bit disappointed considering Sony's audiophile history with their walkmans and LDAC codec.
Yes, I'm nit picking about a $13XX dollar phone but for this price, I was expecting a bit more that just average performance.
For comparison I do have a LG V40 with it's quad dac and it powers my audio technicas perfectly fine with High-Impedance mode.
On the MK ii, I don't get the full sound with out an external dac coming into play.
I'd like to ask other MK ii owners if having just a headphone jack is enough to power your earbuds/iems/headphones.
Going to do a bit more in detail research within a couple of days but I think Sony just wanted to slap a headphone jack just to say it has one.
Ps- I'm no audiophile but having a full sound for the headphones I have is a must.

Thank you! This thread is very interesting.
I have reduced hearing and I badly need a smartphone with high-output. My LG V30 with it's QUAD-DAC has no problem giving me enough volume even on my favourite pair Hifiman HE-4xx.
I was hoping that Sony 1 mk2 was an alternative, but maybe not................ ?

You may want to make the distinction between headphone jacks that can and cannot drive high impedance headphones as a headphone jack that can't can still be good as in clear, little to no distortion with good response and sound reproduction.
In this case its more like LG's has gone out of their way to include a dac that can power high impedance headphones (which is rare in the first place, in addition to the jack being rare) so if high impedance headphones usage is a top priority, then sticking to LG would be recommended.

I have a Meizu Pro usb dac which has a good reputation. The volume of the Meizu is a bit higher, but the audio quality of the Sony is equal. You just have to increase the volume 2 or 3 notches. The Sony uses the Qualcom dac and excellent Cirrus amplifier chips. I use my Beoplay H6 over the ear headphones for listening. The volume being a bit lower is no problem for me, I still can get serious hearing damage if I want to.
The audio is detailed, excellent channel separation, noise is undetectable.

Yeah LG has done the headphone jack justice, but I was expecting a bit more out of the mark 2 for it's price point.
Like hi-res audio. I get it's mainly a photography oriented product. I mean I guess I got used to only using half of the volume steps provided by the LG phones.
I just had high expectations out of Sony in the audio department. Great camera. As for the dac mentioned above, i have a couple so I'm not too worried about getting any more of them. I have a couple of headphone I can try out besides my audio technicas.

The audio capability of the phone is lacking
Bluetooth volume is pretty poor even though it's decent quality
The 3.5mm Jack absolutely doesn't have that much power to drive much more than basic iem 8 to 16 ohm level. Can't push my 150ohm cans at all

Definitely louder than the previous phones. I'm just happy that the jack is back. I did notice a difference with bluetooth vs wired on WH1000XM4. Volume was definitely louder on bluetooth, but can really notice the difference in quality despite LDAC. But that's just me.

But it does have Hi-Res audio. Volume is a bit lower, but is also the curve of the volume control. With the LG the volume control is linear, with the Sony starts to increase real slow, until over half of the volume.

Yeah volume has to be over half way to start making decent sound. Regular buds are fine though. I have some kz iems and it's fine with those. Just higher impedance isn't for this phone.

My Beoplay H6 headphones have an impedance of 30 Ohms. They work great with the Sony. I can't compare, these are the only wired headphones I have.

I think using its headphone jack to push N3AP do not working perfect, the human voice is low, the sound ‘s analysis goes bad, compare to use usb-3.5 dac line. I use IE60.

I think using its headphone jack to push N3AP do not working perfect, the human voice is low, the sound ‘s analysis goes bad, compare to use usb-3.5 dac line. I use IE60.

I haven't tried with a dac, I will try to compare with my XA50ES

Apologies for replying to an old threat, but what became of this? The link is now dead unfortunately. Was it an actual improvement or deleted because it was non-functional? Thanks.

Try to dm peter. I didn't have a chance to save this.

Sony Xperia 1 II most probably uses a Qualcomm audio codec. Can be their flagship Aqstic WCD9341, a dedicated audio chip. Only a proper tear-down will reveal the details. As I found out this audio chip contains a very good DAC section and can produce nearly 1 Vrms at headphone out when implemented in high performance mode.
