Earphone sound quality

Well after Sony & Handtec completly screwed everything up I purchased the Z2 off CPW with next day delivey,
I'm not impressed with the sound quality with the earphones. I've tried 3 different quality headsets and the bundled set with the phone.
unimpressive I'm afraid.

Did you try the Sony MDR-NC13EM Digital Noise Cancelling Headset?

That's the bundled headset

No it depends, in the UK, if you pre-ordered the phone you get the active noise cancelling earphones MDR-NC31EM otherwise you just get a standard pair of earphones.
Do yours look like this? (Make note of how many contact points there are on the plug)

Even in UK I think you can get z2 without MDR-NC13EM. OP should check the model number listed on the little tag attached to the headset wire.
I highly doubt anyone would be disappointed with MDR-NC13EM. I understand sound quality is a highly subjective matter but I still think z2 with MDR-NC13EM is the best you can get from a smartphone compared to other OEM headsets.

I found the sound awful. The "bass" simply lowered the voice and other instrumental features of a song to make the foreground bass sound bassier. When the bass parts of the song speed the voice would then become loud again.
It made some songs almost inaudible.
Tried my earphones (which I had great quality with my previous phone) and the ones that came pre bundled and both sounded the same.
Also couldn't figure out where the noise cancelling was as they where no different to my standard ear phones in terms of noise cancellation.
Gone to the s5 now and the sound was far superior before root, let alone after!

Sony's bass is usually realistic. It's not meant to be thumping like beats. It's usually a nice rounded sound. I haven't got mine yet so I can't comment too much.

Errm what?
These are THE BEST earphones ever on an Android device!

Sounds like you've had normalisation enabled which levels the audio to the same volume - this can have a negative effect on the audio quality overall regardless of what device and headset you're using so this setting should only be active if you're in a situation where you need it (can't think of a reason you'd need it and I'd recommend leaving this setting off).
As for the active noise-cancelling, to ensure noise cancelling is active, first you have to set accessories in the sound settings to "Noise-cancelling headset", then after you've plugged in the headset, additional options should be displayed in the "Sound effects" menu where you can set when the noise cancelling is in effect and the appropriate environment you're in. You should also notice an icon that gets displayed in the notification bar to show that it is active.
You also have to remember that the active-noise cancelling isn't performed on any headset, you can't just plug in a standard 3-pole headset and expect there to be the active noise-cancelling it doesn't work like that.

As I've explained, how you've described what you've done suggests that your opinion while valid has been used for the wrong reasons and when users who have read your opinion which is a stark contrast to the majority, there is no wonder that there's a backlash.
My opinion is that you're biased and incapable of understanding how to operate the technology in your hand thus in-turn creating a false or rather poor outcome to your experiences.

Well that was a bit more constrictive!
I'm not biased at all though, I played around with the settings in various dodgem ways and could never reach ample sound output.
To suggest I am unable to operate the technology is a huge statement with no substance to back it up and again quite rude. You don't know my capabilities and so shouldn't assume I'm wrong and don't know how to handle the tech.
Instead give feedback like you did and then ASK politely if I had tried what you suggested instead of assuming the negative.

Since I am extremely eager to get my Z2, I have a slight OCD behavior when it comes to news about this phone.
In my info binging endeavor, I came across a similar review to yours in a swedish forum. It had the same complaints about the headset.
When I got my first Android phone, the biggest gripe I had with it was the dismal sound output when compared to the iPhone. So I am very sad to hear that poor sound still is something that haunts the Android universe. The noise canceling headset was one of the biggest draws for me with the Z2. I'll have to try for myself, but I trust your opinion since it coincides with others.

Fully agree, I'm using the supplied MDR-NC31EM noise cancelling headphones and the audio quality is superb...when used with the Z2.
bass strong, acoustic setting do make differences in sound and I like various forms of music from classical through pop, house and hard rock
However I did try them in my ipad and the sound was awful, really bad.

Conversely I plugged in my Audio Technica W5000's into the phone and they were plenty loud enough. I haven't had time to really compare the sound quality though but it sounded ok to me
When I plugged in the noise cancelling earphones I thought they sounded really good but again I haven't compared them to anything yet.

Let's stick to the topic here thanks and resist the urge to make this personal... Thread cleaned.

one of the big reason i want to move to z2 is the earphone sound output... and now these mixed reviews are making my decision tough... i am currently using sony xb90ex earphones with my one x and they are good enough... i just hope the z2 upgrade is not a downgrade after all :crying:

I came from a One X and I used ARHD on it with all the sound mods including the additional beats profiles and EIZO DSP modifier and I can certainly say, the output of the Z2 is much better than that of the One X with the additional profiles. I think the Z2 must use a higher grade DAC or something (seems like it anyway), it is certainly more noticeable when you compare both devices without any psychoacoustic settings enabled (so listening to them flat), the One X had a noticeable hiss and crackle at low volume levels, Z2 not so much

This is also exactly my experience unfortunately
My previous phone was the one x with beats audio + headphones, I'm now using the beats headphones with the Z2 and the bass leaves so much to be desired... I've tried all the settings to no avail, as mentioned above the bass specific setting seems to lower mediums and highs instead of pumping bass.

Tip for better music quality :)

If u guys are serious in music playing, u may found that the Z1 usually got some terrible static noise in the background during music playback, especially if u use flac file. (damn even older xperias dont have such stupid problem!! hate it right??)
U may flash dreamingonmusic for better quality, but it wont really eliminate all the noises.
I guess that the noise was made because our CPU arent captable to process the music at the default volume requested by the kernel. But since it's forced to do so, it wasnt done so well and noise was made
(I'm not saying the volume we normally control by pressing the +/- button. It's believed that the max volume you can get was requested by the kernel, then u pick a volume between mute and the given max value)
So what do we have to do?? That's to turn the max volume lower!!
*Custom kernel might be required*
Steps:
1. Open Pimp My Z1
2. Sound Control
3. Turn "Headphones Digital Gain" to a value below zero. (A value that's suitable for you)
The volume will become significantly lower by then, the lower the volume the less noise there will be.

Since everyone needs different volume, i cant tell which one you should get. But at least you can get to a volume that you'll actually need.
Well I know many of you claim that the stock volume is already too low and u guys have to boost it with the mixerpath. This method may not suit you then.
This method is actually discovered by @Chocolatetrain , thank him if you find it useful
When the hell will Sony give us a dedicated audio chip?? HTC got it and Samsung got it!!
Come on Sony starts up their business by Walkman!! So they really want to give us such crap on the "Best of the Sony in an Xperia smartphone" ??

Nice guide, also, I'm pretty sure it's not the CPU, it's the amplifier, which in our case, is fairly low quality compared to other flagships or maybe even some mid-range phones.

CPU cant generate noise...
It may be generated betwen Hexagon DSP (trought the amplifier) and headhone output. I bet on amplifier too.

Most of snapdragon SoCs have the DSP co-processor which one of it's tasks is to handle encoding digital stream to analog signal. However audio data is processed by the ARM CPU, not dedicated audio chip. Interference may bring on way from Hexagon (where signal is weak) to amplifier. Also amplifier can add something bad to headphones
simple example
CPU>Hexagon>Digital to-analog (DAC) converter>Amplifier>audio output

Maybe that's why flac got more noise then aac since it's more complex codec?
btw is it possible to reduce the noise by software method? maybe identify the noise and eliminate it before audio out?

It's strange but I didn't notice any huge noise on lossless codecs were it will be bigger than non-lossless. Maybe you have ****ty FLAC files with recorded noise or player have bad libs or your device have damaged amplifier. It shouldn't matter what data is processed. What player do you use?
And FLAC is simplest than AAC, it's only carry more data and it's real-time decoded (unlike AAC).

I use Walkman player with dreamingonmusic mod
I'm thinking maybe the flac files I got sucks becoz they are encoded by people who bought the disc and AAC might be higher quality becoz they are official version encoded by iTunes.
(well I'm those bada** who keep download and never perchase a disc.)
But seems I got zero noise no matter AAC or flac after I lower the kernel volume gain

sorry OP but i've audiophile grade headphones and i dont hear any hiss. Sound is crisp and quiet good, just like samsung flagships. I use stereo speaker mod, it increases headphone volume too. Even at high volumes theres little to no hum while playing FLACs with PowerAMP.

Doesnt work for me

Good for you.... actually the noise is most obvious in the silent part of songs. It wont really mute on those part but some s**tty noise might be made. Yes, the noise seems much less significant if u use headphone with high resistance. Or maybe your headphone is so good that it can cancel noises.
Btw EX650AP is my primary earphone for this phone and I'm pretty sure this method cancel most (if not all) noises i heard in silent part of music

So samsung actually has worse quality in music but it got no noise?
yea i was also pretty disappointed in the music when i first got the Z1. Need audio mod to reduce it before (even it doesnt kill them all)
Sometimes i really get mad when i hear those "shilishaglag" sound.
Seems to be the problem of the amplifier. We were supposed to be given with S-Master Amplifier but they cut it off in the final product.
Maybe sony mis-calculated it will cause noise
sucks to be guys who dont root or use custom kernel

Camera is the first thing in sony that doesn't get mess up with hardware itself
(well, instead we got the the software to mess it up for us anyway..you know [over-compression])
Orther than that they just pretty much rune everything
Good screen with yellow hue and touch problem.
Nice hardware on board with vibration issue
Out standing sound quality with weird noises, etc.
I hope Z4 will turn out good cause I really like their firmware and sony xda forum.
A lot of thing to mod

Exactly what i think
I really cant get what those guys in xperia software department are thinking
Xperia Z1 is so under performed without mods
btw i really think they should add a better amplifier if they insist to produce such loud sound in earphone mode

They might have done something good with Z3 already cause I heard the only "WoW!" thing is
The new chip for sound enhancement
But I won't get this one expensive device that should have been called "Z2"
They should just release flagship every year and that's it.
I'll wait for Z4 or Z4 compact.
Will not give up on them yet.

S6 audio quality..

It seems that we have a winner for audiophile headphones listeners...gsm arena has confirmed in audio quality test that S6 is better than last year htc m8. One drawback is the volume levels ( this is samsung registered trademark) but this is easely resolved by adding an external amplifier or by rooting and modify the volume levels.
I'm waiting for real world reviewers!!
P.S. exynox + wolfston was always a winner in this category and it seems that this time Samsung has a winner...

2 points difference in dinamic range or noise level means for me nothing considering that stereo crosstalk is now the best for any phone.
Samsung with snapdragon had prapund -55 and now we have -83. The days with the sound delivered in the center of our head ar gone, now we have space in music!

So happy to see this. I still don't understand for the life in me why Samsung devices always have low volume output through headphones. Its very annoying in the gym.

I was going to post the same.
Just for reference, dB is more like a logarithmic scale. It means 70 dB intensity is 10x more than 60 dB. Similarly 80 dB intensity is 10x more than 70 dB.
The difference here is 5.4 dB. This means that the actual sound intensity is increased by 3.46 times. For quick calculation of difference in sound intensity from dB:
- Find the difference (which is 75.9 - 70.5 = 5.4)
- Divide this by 10 (5.4/10 = 0.54)
- Find the base 10 antilog of 0.54 (use this antilog calculator link, which is 3.46 times)
And somehow GSMArena found S6 to be quieter than S5
The loudspeaker is average in loudness and quieter than the Galaxy S5

maybe cheap earbuds or possibly need some ear cleaning?
my S4 i rarely go past 60-70% while at the gym and it's more than loud for me. i don't like taking my earbuds off and hearing my ears ring afterwards.. it's no wonder people seem to be going deaf these days..

Gsmarena has found that speaker loudness is worst than s5, not the headphone volume...

do u still listen to music from ur phone with the built in audio jack? like seriously? -_-
there are quite affordable audio AMPs and DACs combos available these days, and they DO make a difference. why not get the portable ones and use them to power ur music?
thats the dilemma, people are ready to spend like US $800 on a phone but cant buy a US $50 audio device to power their music and call them selves, "AUDIOPHILE"....

thats the dilemma, people are ready to spend like US $800 on a phone but cant buy a US $50 audio device to power their music and call them selves, "AUDIOPHILE"....

Oh gawd...one of those...
Do you really play games on your phone? That's what a PC is for..
Do you really take pictures with your phone? Buy a real camera!
Do you really watch movies? That's what a TV is for.
A smartphone is a jack of all trades master of non. So yes..I listen to music on my phone. And I expect it to do well.

Think the same. Yes, I listen music on my mobile phone, and, for me, it's something important.

If you rely on the USB DAC for audio you will lose the ability to pick up calls handsfree while listening to music, and more importantly stress the USB connector if you are listening on the go. My only concern with the headphone audio is a comment made by François Simond ( Supercurio ) about his listening to the S6, possible artifacts in resampling 44.1 to 48k on the device.

any idea if its better than the note 4?
its my current music device, carrying 15gbs of music (mp3 and under 320)

It's almost guaranteed to be better. The Note 4 uses the built in DAC on the Snapdragon 805 chip which is considered to be fairly poor. The S6 on the other hand will use a Wolfson DAC which will sound great stock and even better when developers begin tuning the sound output.

This is the main reason I'm getting the s6 (don't know if I'll get the edge or the regular. Depends on pricing t-mobile gives). Last phone with a dedicated dac was the galaxy note 2 for tmobile with the exynos chip. The dac and everything sound a great and a custom kernel by boeffla taped into the dac to unleash it's full potential. I'm not an audiophile but I do like my music to sound good on mobile. Converted all my flacs to m4a and have the vmoda m100 and that's plenty for me. Have looked at USB dac but I don't want to have to worry about anything else. Also Samsung pay has me drooling a little but. Hopefully tripping KNOX by rooting the thing doesn't Disable Samsung pay

I'm not sure if you tested headphone output or speaker quality but the DAC will have most of an effect on the headphone output. A great DAC can't make up for crappy speakers.

Note 4 is louder in Headphones. I personally couldn't care about speakers that much, as long as its loud enough to hear my callas and texts thats good enough for me and the note 4 is louder than the s6 in speaker too.

Could U compare Mate 7 sound output on earphones to Galaxy note 2 or Xiaomi Mi4? The first one had very good sound quality but Mi4 has disappointed me in this field.

I have plugged in my headphones to many other devices and phones without an extermal headphone amp.
I can say for instance, I was quite impressed with the sound of my LG G2.
Mate 7 compared to my LG G2 is big difference...
My DT1350 headphones sounds very well without a headamp of course.. I have plans to buy a good USB DAC for my phone when I get the money
Like this one http://www.headstage.com/Arrow-5TX/....html?XTCsid=d99628f16e91ce69c9d50b1b0173b532
It is small enough to have in my backpocket in my jeans.
Further I try to avoid listening to headphones as much as possible since it will cause a big strain on your ears due added sound pressure (I have mild tinitus)
But when I am on vacation or travel to a different city and not at home it can be nice to have a good portable sound.
At Home I have an Antelope Eclipse AD/DA converter and Trident HG3 speakers.
But yes... this DTS "bull****" Mate 7 is just a marketing term just like this braindead "retina sound" for people who do not know or care much about audio..
DTS have a good effect on the Phone speakers since it adds more bottom and richness to the sound but with headphones it just adds "fake sound"
it is not a sound I would "trust" . With that said I bought this phone knowing it was not perfect, I drop my Lg G2 in the floor..I was desperate to get a new phone was and I did refuse to buy the Note 4 because of the insane price, plus I admire good screen to body ratio, a big smart phone today is NOT smartphone if there has been no focus to slim down the dead area, I want as much screen area as possible otherwise it's simply and idiotic construction, Huawei and LG are one of the few who understand screen to body ratio is important.

Blackinfinity, you only THINK your Headphones sound good with other phones, TRUST ME, i got into audio and i for instance was using these http://www.amazon.com/Beyerdynamic-...id=1428598957&sr=8-2&keywords=beyer+dt+770+80 which are 80 ohm,s like yours and i thought the headphones sounded OK, then i got a headphone amp, and it became VERY apparent that the headphones want alot more current to sound good then what comes out of your phone,seriously when i plugged em into the amp, i thought i had seriously upgraded my headphones, sounded ALOT better

I have the d880 too... They are hard to drive and react to amplification a lot more..
Dt1350 are made to sound good unamplified since that his how most people use headphones these days... However I still want a good portable headphone amp.

your headphones are 80 ohms they will improve with a amp

I'm not an expert in audio/sound.. but even my ears could tell the big difference! I'm not talking just about the LOUDNESS.. but the richness of the quality of the sound!!

Audio is not as easy as you say, impedance synergy pairing and headphone / IEM play a large role in the perception you have, for me with my IEM's collection the Mate 7 sound realy good, better than my old Wolfson Note2 using Viper4Android or Boeffla kernel.
Here the audio test part on GSMARENA to compare between both:
Find 7
The Oppo Find 7 put in a stellar performance in the first part of our audio quality test. It had excellently high volume levels to go with its very clean output. Barring for the slightly high IMD reading this is one of the best score sets we've seen lately.
However, the smartphone faltered quite a bit when we plugged in a pair of headphones. Its frequency response started missing the mark now and then, the IMD rose further and the stereo crosstalk hiked quite a bit. It's not as bad as the stereo crosstalk disaster that was the 7a, but elsewhere the more premium member of the pair lagged behind its stablemate. Volume level dropped as well, adding up to what was a good, but not quite flagship-worthy performance here.
Find 7a
The Oppo Find 7a audio output is certainly among the cleanest we have seen when the smartphone is connected to an active external amplifier. Posting excellent scores top to bottom in the first part of our test, the Find 7a was also nicely loud, producing one of the best performances out there.
Plugging in a pair of headphones tells a different story, however. The stereo crosstalk increases way beyond the point where it can be considered as good, or even acceptable. The other readings remain great, but the high cross-channel leakage has the potential of damaging the whole audio experience for more exacting users and put the Oppo Find 7a below the current crop of flagships as far as audio output is concerned.
Mate 7
The Huawei Ascend Mate7 did excellently in the active external audio test, posting great scores and showing no weaknesses to its performance. The only thing to potentially frown at is its sub-par volume, but quality-wise it's right up with there with the best.
Impressively enough, plugging in a pair of headphones causes a very minor increase in stereo crosstalk - in this scenario the Ascend Mate7 ranks even better compared to the competition, which often see more degradation. Alas, the volume is below average here too, so we can't really say it's the best phablet for audio playback, but we can certainly promise you it will play every track the way its authors meant it to sound.
With my sensitive InEar SD3 I have plenty of volume, I listening beetween 3-5 most of the time, I dont want to end up deaf

HIfI option, why does standard sound better than super ( various headphones )?

I own a few expensive headphones and IEM's that cost more than this phone.. Why does SUPER ALWAYS sound worse than standard in the hifi sound option? Super sounds muffled on every earpiece I used.. Its like its backwards or something..
so is standard the snapdragon DaC and Super is AKM dac? Or is both AKM? Mostly bought this phone for its audio capabilities, I ride over 100 miles a week on a cycle and always tune out.
HELP!!!

Also interested in the answer to this, I thought I was going insane as on my custom IEMS standard sounds better than super which seems muffled but if I swap to a pair of cheaper earphones then super gives better results.
Want to know what each of these modes do in terms of DAC or filter being used?

Super sounds waayyyyy better than default on my A2017G using OnePlus Icons.
I should know as a music producer and audiophile.
The sound is a lot deeper and thicker. Also the bass is a lot cleaner and the high frequencies are also more clear and less 'dull'

I'd like to know how others are finding the difference between standard and super headset hifi. Pls also post what earphones/headphones you are using for this.
For me, JH Roxannes and Sony EX1000 sound better with standard. If I use Westone UM30 pro then the opposite effect, super sound better.
I can't believe the phone can tell the difference between 2 earphones and would change super and standard accordingly.

beyerdynamics custom one pro.
no dolby.
with super the instruments sound a lot clearer (except for the increased volume in bass frequencies) as in i hear every single vibration of an instrument. e.g. when a hi hat is hit i audibly "see" how it swings.

I don't use dolby either but standard sounds better on my Roxannes than super. Same effects as you experience but on standard vs super. Highs/Mids/Bass sound clearer in standard. Super sounds muffled in comparison and bass is increased but muddy.
Unless standard and Super are reversed on the chinese version A2017?

May be my earlier post in other thread can help to answer to your question regarding DAC.
http://forum.xda-developers.com/axon-7/how-to/stock-music-player-t3474463/post69069304#post69069304
The only thing is not clear yet is the analog part. I suppose that it is in separated, already not named chip and both DACs drive same amplifier. The volume difference between Standard and Super would be because of different analog signal level. It is my opinion but either I can imagine that it is on purpose indicating that something happened.
Why do you hear standard sounds better than Super? I don't know. I checked how standard sounds (good) but I always use super mode.

I brought this up in a previous thread, glad it's still being discussed.
One issue lies in confirmation bias. Anyone doing testing on their own and knowingly switching between Standard and Super could have psychologically skewed the results. Since the software named one setting "Super", the weight of average users opinions may bias towards that. The only way to truly test it would be to have a full blind test done.
Since even I don't want to bother anyone to help me set up such an involved test, I did some rudimentary testing with my Shure SRH840, Sony 7506, and Triple Fi 10. I'm finding that Super increases the overall volume, as well as increasing mid-bass response and some treble.
I have an unsubstantiated theory on this. First, Super setting could be a sales tactic equalizer designed to "wow" the average consumer. It's a well known audio industry strategy that preys on the human brain's tendency to rate slightly louder audio sources as higher in quality.
Secondly, this setting could be designed to give perceived improvements using low quality headphones. The fact that several of us observe increased mid-bass and treble, areas that cheap headphones sometimes severly lack, may be an indicator. Let's not forget that in the box, the Axon comes with a cheap set of headphones that are many buyers' first audio experience on this phone, which ZTE would want to leave an impression.
If this is true, it makes sense that many of us with higher end headphones with more accurately balanced frqeuency response would find the Super setting to be inferior in use. Again, none of my claims can be confirmed unless professional testing equipment and a blind test method is used.
I remain skeptical in regards to questions of this setting toggling between a Snapdragon DAC and a Axon specific Hi-fi DAC. When quickly switching between Standard and Super, there's virtually no pause in the audio playback, with linear fade outs and fade ins. It seems odd that if the phone was truly switching between sending the audio to two different hardware chips, a more prominent pause in audio playback should occur.

So is it true that you cannot use Dolby and process audio using the AKM DAC at the same time? I read that somewhere, you can use either one or the other

I believe that's not true, it may have come about from Poweramp users. If DVC is disabled in Poweramp then Dolby can be used. I assume that Poweramp uses the AKM dac.
I'm curious how the Axon 7 is setup. If only the AKM dac is enabled or if the S820 dac is also enabled. I can't work out if or how to switch between them. If there is any way to show which dac is in use that would be great as it's all guessing right now.

If that's the case then no concern over super vs standard. Both modes use the AKM dac and the difference being heard is software/filters/dsp being applied
We could push the argument to say that standard is the pure output out of the dac with no coloration being added so no surprise this sounds most transparent, clear with decent earphones.
Super would be for lower quality earphones to add back elevated bass/highs so artificially compensating for hardware defecits.

Not at all.
I've tested with several headphones and the super settings adds a lot more depth. Default sounds a bit flat. Not in terms of bass or treble, but widening, clearance, and especially the low-end sounds a lot muddier.

Not exatly. If you use flat mode there is no colorisatin in both. As I know 4491 is not able to oversample and convert 16 or 24 bit to 32. 4490 is able to. It should make sound better theoretically. Beyond these 4490 has many switchable filter option. Don't mix it with DSP. Usually it is called soft or sharp mode etc mode. Unfortunately ZTE doesn't make it availabe for user and I don't know what is the default selected option but difference between these option is so tiny that you can judge just after long term listening if you can at all.

Something is wrong with your phone in particular. Reset it or send it back.
I saw a friend with Axon 7 dealing with exact same issue.
I got mine and its working like its supposed to. Super enhances the sound and dolby gives the open dynamics.

Not both mode use AKM DAC but use different type of AKM DAC. 4490 is more enhanced than standard 4691. 4490 can oversample and convert bit depth but I already said it in earlier post. There is no software trick to make it "better" on cheap headphones. A7 was made for audiophiles too, why would they have done that? For this purpose a tone control would have been enough. I suggest to check how another A7 phones sound, may be yours has problem.
Otherwise today I listen music in standard mode too. Comparison was a bit difficult because I cannot set same volume level. The difference is 1.5 click between two mode. Never mind my intension was and long term test. I played only CD quality music and there is no question about that both DAC sound very good but differently. Standard sounds like typical CD player. It is a typical sterile digital sound. The Super is full with air and space. Everything is more clear and enjoyable. It sounds analog way. After this I don't know whether is it worth to compare with HD audio record too?

Now that would be a surprise to me as I saw AK4490 was used as DAC for playback but AK4961 was used as ADC for recording. I never considered they would have both wired for standard n super.
Where can we find supporting documents for these 2 modes since even manual skips on details and just says you can change it within headset hifi?

4691 is ADC and DAC in one chip while 4490 is only DAC. I haven't found well detailed document. All you can do in this question is that you read ZTE and AKM releases carefully. Also you can find some detail on site like Android Authority or Youtube etc.

From ZTE site, it looks confusing:

Sampling Frequency: 384 kHz
THD+N: '112dB
S/N: 120 dB
Recording
Channel: 3 channel (HiFi),1 channel (VAD)
Resolution: 32 bit as per spec (24 bit as per performance)
Sampling Frequency: 96 kHz
MIC max input: 2.02 Vpp
S/N ADC: 102 dB
Conference Mode
Directional Recording: Dimensional and Omni Directional
Recording Range: Up to 7 meters (approximately 23 feet)
Dedicated Audio Chipset: AKM 4961 + 4490
- 4961 - HiFi main chipset to provide HiFi and recording features
- 4490 - Independent amplifier to enhance HiFi playback (AK380)
It makes it sound like 4961 is dac and 4490 is the amp. At least for the conferencing, for playback it only mentions the dolby which is software. It also adds (AK380) to the line mentioning 4490!
