Now here is the original message :
_______________________________________________
The Galaxy S is a top-notch mobile audio hardware, but Samsung is currently destroying it when you plug a headphone.
A friend of mine and myself have immediately noticed that the frequency response is just not "right"
Very disappointed by what I heard, i've scratched the surface and here's what I found :
When you plug the 3.5mm jack out to a line-level device (ex : sound card line-in, hi-fi amplifier)
- Line out frequency response is perfectly flat. It can be called extremely accurate for a mobile device.
GSMArena review (plugged to a 20kOhms impedance line-in) confirm this excellent result
- Output level is standardized for line-out output.
When you plug the 3.5mm jack out to a headphone device (any headphone)
- Headphone frequency response is modified.
My ears would say approx :
+6db from 35 to 200hz
-2db for 500hz to 5khz
+6db from 10khz to 12khz
+3db from 12 to 16khz
The result sounds like a strong loudness filter.
And you can say good bye to most of voice definition, instrument musicality, sound stage, stereo image and... listening pleasure
- Sound level is lowered in recent firmwares (not in stock JF3). I guess this is because i'm in France, and there is a law here to limit maximum sound level.
There is a side effect : this limit is done by lowering the analog level of the DAC output.
Great news is that for every in-ear isolating headphone like me, the noise level is much reduced compared to JF3
How to correct this stupid setting
If you're like me, you can't stand using such a good hardware crippled by such a dumb configuration.
If you want to get immediately a sort of fix, you can enable the "Pop" equalizer in music player.
It applies an equalizer that boost mid frequency and helps fighting the dumb loudness-style equalizer.
This is not a real solution because
- Pop equalizer reduce too much bass and high frequencies
- Pop equalizer comes with a dynamic compression, that will alter sound volume too, depending on the music played.
- It works only in the samsung mp3 player
This equalizer can be disabled by some settings in Service Mode !
Yesterday I stay up very late to find the appropriate settings in Service Mode.
And guess what, i found how to disable this stupid equalizer, and was so happy
Audio response was accurate... really, fantastic result !
But knowing that (most?) servicemode settings don't survive reboot, I did so.
Too bad, sad EQ was back after reboot, and the modification applied did not work any more.
I guess I changed so many (a bit random) audio parameters that i eventually found the good combination. I don't find it again, that's why I call you for help
Here is where the settings changed the sound (realtime) :
Go to Service Mode *#*#197328640#*#*
Code:
[5] AUDIO
[2] HEADSET
[9] Diamond Solution
[6]1Mic TX(OFF)
[2]Fir_Coeff Table
Here is what we found here :
(fir is for Finite-Impulse Response = equalizer parameters)
Code:
- Headset Diamond Solution1Mic
[1]fir_coreff 0 : 0xffff49
[2]fir_coreff 0 : 0xfffce6
[3]fir_coreff 0 : 0xfffab3
[4]fir_coreff 0 : 0xfffccb
[5]fir_coreff 0 : 0xfff0e9
[6]fir_coreff 0 : 0xffffc7
[7]fir_coreff 0 : 0x3e4a
As blurry as I remember (again, it was so late, not 100% sure ) I put all these to 0, and headphone equalizer was gone.
But... i must have changed some other parameter, anywhere in the [5]Audio settings.
I'll try to find again the good settings, but any help is very welcome !
After finding the appropriate settings, you can count on me to find how to apply these settings permanently (surviving reboots)
Have a nice hunting

How do sgs know what is connected to 3.5 output...?

It monitors the electrical impedance of the device attached.
A line-in is typically between 10 and 47 kOhms, headphones are between 300 and 16 Ohms

Yeah I agree that's strange, and... a very bad idea by Samsung.
I was accustomed to very good the iPhone 3Gs headphone output (used with surprisingly good and cheap SoundMagic PL50).
The first music I listened with the SGS i got the feeling "Ok, this is different, i'll probably get used to. 3Gs may not have been so accurate".
But after 2 days i could not get accustomed, so i checked :
PC sound card, Netbook sound card, cheap Galaxy Spica sound approximately the same (minus noise, distortion and some poor infra-bass response on netbook and Galaxy Spica)
Only device with a loudness sound signature, poor mediums : Galaxy S
The fact that a friend got the same feeling (without knowing mine) confirmed that this wasn't just a feeling ^^
I guess we could measure the response with a Y jack doubler.
1 connector plugged on headphones, the other to a computed line-in running RMAA.

Does the SGS's audio chip could compete with the one in iPod touch?
Coz I compared the output from the same headphone and the same song file.
Then I noticed the huge difference in sound quality btw hose two devices (I tried all EQ in SGS but the output isn't quite good).
It's great to hear that there still has the way to improve the SGS's output quality.

Thanks for info , i will try this settings.
If this is true , Gsmarena are not doing weel this measuremens , to analyce sound quality (especially frequency response)
in headphone out (usually handheld device DACs, have diferent Pinage for line out and headphones and
lineout is not used) you must put a load (tipically 16-32 Ohms)or better a headphones in parallel with sound card line in.
I dont know how samsung can manage to swith between line and headphone out by software (is possible but very strange).
PD: i saw a wolsfon chip in dissasemblig pictures (wolfson or Diamond DAC ? ).

Hello tra !
Sure, SGS's audio hardware can definitely compete with iPod touch & iPhones sound quality.
I'm found of the iPhone 3Gs SQ, but sold mine to get the SGS.
I've just checked right now the line out quality with RMAA to confirm GSMArena tests. I confirm the accuracy of the SGS Review results.

Yeah i'm pretty conviced that what you heard was the bad EQ added by Samsung, maybe adequate for very low end headphones but a reall mess for every other good equipment.
I listened to some music after finding the service mode parameters and SQ was really fantastic, as good as I remembered with my previous iPhone 3Gs.
Wide but tight bass response, clear mids, precise highs, you know... everything.

But for now, GSMArena analysis is the best we get for most phones, even if it only measure the quality of the "line out", and not "headphone out"

Do you think that the Samsung Galaxy S includes a Diamond DAC ?
I did not know Diamond was a Dac brand.
I read somewhere that it may use a Cirrus DAC, but based on Service Mode menus you probably just made a very good guess
And that's definitely the right place to look in settings, thank you !

I find that equalizer set to classic and effects to either wide or clarity, work best for me.

Salut robert
Both settings (EQ and effect) you use tend restore a bit of sound clarity lost by Samung's bad EQ for headphones ^^
Hopefully you wont need any with Samsung EQ disabled.
BTW with most good headphones (especially in-ear), we don't apply any equalization or effect.
That's the goal here, and often the only way to get an accurate and non-fatiguing music reproduction.

Good news folks, I found the settings again !!
It was just under my eyes, almost right in the first port I wrote for you.
I try to reboot the phone and re-do them to confirm... but right now... this sounds Fantastic

thanks for your reply supercurio.

Do you do any analysis with righmark and a headphone load (with a headphone splitter)? , if yes , please post frequency response graph.
I would do , but i returned my SGS (GPS issues).
Thanks

Hehe right, Wolfson show the Samung weave in their homepage, linking to detailled PR.
Do you know if it's the WM8994 (read on a blog : amot wordpress com , sorry can't link) ?
BTW i guess that the equalizer we tweak is the hardware parametric equalizer Wolfson talks about
This hardware EQ can be interesting with if clever used
I'll try to buy some y-shaped jack double tomorrow and will run rightmark tests.
Do you recommend using 2 simple 32 Ohms resistors or a real headphone plugged ?
I guess that result with real headphones attached will give some crappy numbers (even if True)

Allright folks, here is a working solution !
Run the Service Mode app by typing *#*#197328640#*#* like a telephone number.

If it is possible Ok, but not worry i will bought a new SGS soon , and i have a splitter.
I usually do this test with 16 ohm headphones (Google site:rmaa.elektrokrishna.com rightmark audio 16 load)
i also own a 27 ohm UM1-UM2 westone.
my biggest worry are lower frequencys with low load. I am not an audiophile but for me is very
important the audio quality, for me in SGS is great (maybe not perfect) but this is the first phone
that can replace my music players (cowon d2 , zune 80 , zen micro).
Thanks supercurio .

Thank you awesome job!! with Sennheiser IE8 it sounds so well now!!!!

This is a completely different topic altogether, but I was wondering if anyone else had this problem. After my phone has been on for a few hours, when I plug in headphones or speakers, it makes a buzzing noise and sounds are distorted. Its easily solved by restarting the phone, but can get rather annoying.

Just tried some big film scores and yep the sound is better, I was unsure how much it would change but its very good, all owners should really do this, just seems to be more clear and have more kick to it.
using shure 530 headphones

to the above, I think that problem is having tv out to on, switch it to off, if that does not stop it then its another problem.

Terrific database pepitodequetequejas !
Congrats, I'll take a good look at it now and then
From what i hear right now, SGS drives my SoundMagic PL50 with ease, even at lowest frequencies.
Frequency response is similar to my previous iPhone 3Gs, but general feeling is :
- less harsh, a bit less punchy
- more controlled mediums, and softer at the same time. better voices and less "saturated" guitars
I love the musicality we got, it's a real pleasure.
Noise level is maybe less than 1dB higher than on 3Gs.
For your RMAA, you can maybe compare several firmwares : JC3 output level is maybe 3db higher than JM2 with a french SIM (signal and noise)

Workaround for noisy headphone jack

Some of us have had problems with a noisy Galaxy S3 headphone jack full of distortions and static. Those of us that have it have noticed it for every phone. I wanted to find out why. I have a number of headphones and they all have different impedance (ohms). The headphones I use while out and most likely to use with a phone have a very low 15 ohm impedance. The GSIII is unusable with these headphones. I have a 25 ohm pair and the phone is noisy but tolerable. I have a pair of 50 ohm headphones and the phone is just fine with them and I don't notice any problems.
That explains why a lot of people have no problem with the headphone jack and others find it terrible no matter how many times they replace it. The solution is to raise impedance. I chose this volume knob cord (http://www.amazon.com/Shure-EAADPT-...1348070226&sr=8-1&keywords=shure+airplane+kit). There are cheaper ones, but this one doesn't introduce any obvious distortions that I can hear. I just use this and set my phone's volume to 2/3. Then I just use the knob to change volume. Everything sounds fine now. Not quite as good as a Wolfson, but nothing to complain about at all.
This might seem obvious to some, but it's not to everyone and it might help someone doing a google search.

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.

I am one.
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).

High impedance earphones.

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..

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.

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

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

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.

[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.

The audio quality is perfect with my XBA-N3AP or WH1000XM3

Oh snap, how are the XBAs?
Currently, I'm using AKG N700nc2( using them wired )

XBA are amazing, well balanced and no extra bass like many earphones.
With an upgraded cable it's even better [emoji106]

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.

Poor volume, I can still get hearing damage by the levels of volume here.

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.
