Headphone hissing sound - Xiaomi Mi A1 Questions & Answers

Is this headphone hissing sound common in all mi a1 phones or is there some hardware issue?

hiss
Is your phone plugged in and charging when you get the hiss? im thinking its a hardware fix. It's not easy to notice it, at 1st I thought mine was OK - but play any tune that has some lower volume parts and you can hear it. Also, play any MP3, pause it - and you will hear the high pitched whine / hiss - it sort of sounds like electronic interference of some sort. So the sound is always there just masked until quieter passages. To test , use headphones, turn up the volume, play an mp3, use YouTube - anything with audio, then PAUSE the item and listen - you will hear a second or so of the noise, then it will stop.

Just noticed this last night :/. I was using apple earpods. changed to sony headphones, and the issue is gone. weird though

I'm interested in buying this phone but I'm holding off on it because of this widespread headphone audio issue. I'm surprised that this is such an issue... especially since the phone's supposed to have a 10v amplifier and Xiaomi's marketing the phone's HD audio? WTF.
I just need to know if this is affecting only Indian models or all models.

It's not that big of a deal mate you can only for a couple seconds when it goes silent, the audio on this is great

What about this thread? https://www.reddit.com/r/Xiaomi/comments/71xrqz/mi_a1_headphone_static/
Seems like a fairly serious issue. And I like my volume loud (90+) so if static is apparent at higher volumes, I'll be extremely upset.

I'm extremely skeptical about the audio quality of this device. I can totally see it being above average or devices from the same price segment but I'm sure it isn't something from another world. People seem to over praise it and I'm sure most of them are just considering loudness as audio quality.

with some half decent earphone this phone sounds great not just loud mate

I'm having same issue.
This might caused by the audio amplifier boosted the volume gain which increases the static noise and taints audio clarity.
Earphone/headphone which has more than 35ohm impedance and low sensitiviy pressure level below 98dB might have better chance with the boosted gain.
Even on ATH M40X, the background static noise is still noticeable when sound is played. *sigh
I wish the amplifier is disabled by default and could be enabled on demand from equalizer app.

@chrone Exactly, I'm willing to see how it will perform with biquads mod (if it is possible)

Hey guys I've just noticed that I get the same hissing sound on my nvidia shield K1 but I never noticed it lol

I just tested it with my bluetooth headphone. It's working good and I don't hear any weird sounds/hissing etc. But does the amplifier work if I use bluetooth headset?

Maybe someone can fix this in a custom ROM?

Seems like a low impedance problem? There is a thread on reddit about this:

Audio Quality is awesome on both the speaker and headphone jack. I have no issues. I am already getting mod like quality from this one.

I have this problem too using Audio-Technica Mx 40x and xioami hybrid. It's becoming quite annoying

Does this phone hiss etc. when playing music?

Does this phone have any kind of hissing sounds etc. when playing music through the headphones?
mine does not. sometimes a crackle or pop, possibly due to the decoding, but otherwise hiss free.
It depends on the headphones and their level of sensitivity.
Sent from my Liberty using Tapatalk
Yes, both of my Arias hiss with headphones. It's especially annoying when listening to spoken word podcasts. I have tried at least 6-7 different brands of headphones and they all hiss. I listen at very low volumes and hear the hiss more at the lower volumes. Also, the program doesn't matter, so I suspect it's due to a hardware limitation. Does anyone have ideas for reducing the hiss?
NO!! If you use the proper headphones. (Skull candies or other better quality) then your fine. POS headphones will do that on any high quality phone.

[mod idea] Stereo sound on the Xperia Z1, like the Z2!

I just had an epiphany.
The Sony Xperia Z1 does not just have one speaker. It's got one on the bottom, but one on the top as well used for calling!
Now my question is, could someone with more knowledge of software modding make the earphone speaker produce the left channel of stereo audio and the bottom speaker the right channel? This must be possible.
I came to this realisation after having made a call and opening an audio producing app which surprisingly used the earphone speaker for sound (yep KitKat still has this bug). At max volume, the audio was still pretty audible, though not loud at all, but useable in quiet areas.
So please tell me if I struck gold here with this idea, or is impossible for some odd reason?
+1 That's a great idea man, hope the dev's see this and work on this.

Thanks, I just had the issue again and used it to my advantage. And actually, at the highest volume which is relatively low compared to the regular speaker, music sounds much fainter than the bottom one. I'd love to see a developer try this, but it's definitely not going to be as good as the Xperia Z2. There would have to be a kind of equalizer for the upper speaker alone, to set it to ones liking, together with a toggle in the settings menu to revert back to mono audio.
It would be possible yes but it 1)could damage incall speaker having it louder then it is standard2) wouldnt make much difference unless the speaker could produce clearer bass and therefor removing tinny audio

1) I often call with the volume at max. This is still audible from an arm's length distance, as long as surroundings are relatively quiet. Aren't 'loud'speakers supposed to be loud?
2) If a toggle could be modded in the settings menu, I wouldn't actually mind the odd quality as long as it's stereo. I'm not expecting any superb bass: even sound similar to my old Nintendo DS Lite is good enough for me. I haven't been able to test the earpiece speaker too extensively yet, but I don't believe the quality is all that poor either, as its quality determines the call quality of the device which is expected to be good on a flagship phone nowadays.
Actually playing radio for the first time on the z1 today, the speaker was playing at stereo mode and it was amazing just like my old HTC one.
When I went back to walkman, it went to mono and blank audio without base or nttn.
If there's a reason why radio plays on stereo mode with the nice base and all, there should be a way to make that stereo work system wide.

Wait what?
This stereo mode you're talking about... was it truly that one speaker output the left channel and the other the right? At equal volume? And did it actually sound good? I haven't heard both speakers produce audio at the same time yet. Now I'm interested!

I think the FM radio made use of the second speaker to produce the stereo sound. You try it as well. You will feel the difference of sound output of FM and sound output of walkman or any other audio source of the phone.
It sounded so good that I've been jamming to FM radio all day.
Sent from my C6903 using Tapatalk
I was thinking about that too. Lets say if you turn up volume to 80% than only bottom speaker overtakes all because of overloading, but till 80% both speakers are working at the same time... Or at least until the sound is same on both speakers

This would be terrible. The speaker on the top is not meant for playing loud sounds whilst the other one is. That would not balance the sound output AFAIK just having 2 different types of speaker is worse already what more this? But still yeah maybe possible.

I tried it yesterday, but to no avail. The stock FM Radio app (you must mean) only shows "stereo" in the top right corner but when set to speakers, the sound was really just mono. When I covered up the bottom speaker, all sound was gone. Are you very sure you had the upper speaker able to produce at the same volume as well? And can you reproduce it?
I noticed an audio bug when I called just before, but I don't call very often and now I can't even reproduce the original bug.
Great news, everyone!
STEREO SOUND IS NOW POSSIBLE ON THE XPERIA Z1!!

Follow this link and install the .zip file on your rooted Sony Xperia Z1. It truly works, I'm amazed!
(If only they could make a toggle app and adjustable volume levels per channel, that'd be great)

Sony still wont learn about sound output

I've owned the Z1, and the Z1 Compact. Now I'm hearing Z2 has the sale volume/crackly output.
I wear an earphone plugged directly into my phones jack when I talk and drive, and the audio quality on every sony phone is TERRIBLE. Crackly, distorted sound and every time the mic on the earphone touches any part of my shirt it cuts out all volume. I've tested this with 6 other android phones and no problems. Strangely though Windows Phone also suffers from this problem. Also audio output through a 3.5mm aux cable into the car produces extremely quiet sound on the highest volumes.
How has Sony not fixed this? I feel like this is bush league stuff.

So you're telling me when you plug in earphones directly into the jack, there is no change in sound, no crackling audio, no clarity or volume issues at all? Try plugging those same earbuds into another modern android phone or iphone and you'll hear zero interference or crackling issues.

Can you check your source material of what you're listening to? It may be compressed on the high end.
And owning Z1, Z1 Compact and now the Z2 is kind of unbelieveable if you just want to come in an trash the Z2. (Not that I'm accusing you of this but I would have posted this issue on this forum if it was discovered on the Z1)

I'm talking about listening to spotify on extreme quality over a 4G LTE connection, or simply speaking to somebody while driving hands free.
I had an HTC ONE and plugging in the same iphone headphone into it it sounds like im speaking on a landline with no interference or static at all. Every sony phone ive used experiences this, it's very strange.

That is correct..
I have the digital noise cancelling headset (MDR-NC31EM) and there is NO crackling..NO issues at all.
Totally agree with krabappel2548 , fantastic sound quality..:laugh:
I used the Bose noise cancelling headset and it's awesome. No issues. One thing i noticed, with the case you have to be sure the earphone jack is seated properly.

I don't have Spotify so I don't know what it means in terms of extreme quality. They could be upsampling a bad source and call it extreme quality.

Spotify extreme quality = 320kbps encoding. The best you can get for streaming right now.
No problems here, the noise cancelling headphones are excellent too,
I had that same crackling on my Lumia 800, I could hear it when on low volume or on pause, really annoying.
I think most people just don't notice.

Yh i have the same issue on my Z1. I checked with CM11 or AOSP and there is no crackling in low volume so this is definalty not a hardware problem.
To reduce this Crackling sound while ising Stock i download a custom Kernel like DoomLord's and use Pimp My Z1 (or any app you prefer) to turn down the gain the in the sound options. The downside is that the volume becomes lower. This method doesnt get rid of it completely but it does reduce it. I honestly dont even bother with stock anymore i just use CM11 or PA on my Z1.
BTW i think this Noise is called Sibilance. G3 users are experiencing the same problem.
Also turning off ClearAudio+ reduces the crackling sound.
Cracking insinuates that there is a popping noise. I hear none. As far as noise, yes. There is a faint hiss at low volume, extremely faint. Sony isn't exactly a leader in SNR but the audio isn't necessarily bad. Anyone who is using ClearAudio+ (which is total s***) shouldn't even comment on audio issues, definitely turn that off. Clear Phase on the old 4.2.2 ROM caused some definite extreme distortion and cracking over Bluetooth (but not the headphone jack) but that has been removed in the new ROM.
Sibilance is the hiss sound you hear when people make "S" sounds into the microphone. It can be really harsh, but usually reducing frequencies around 4-6KHz will reduce the problem. Sibilance is extremely prevalent in analog FM Radio.
I currently have an issue where sometimes I only get sound out of one of the noise cancelling headphones. I have to rotate the headphone socket in the jack to get sound to come out of both. Sometimes I also get crackling on my e10s when the phone is in my pocket. I think I have a faulty headphone jack as the MDR1 work perfectly on my Z3TC.
Speaking with Sony UK they asked me to do a repair on the phone which seemed to help a little but the problems still exist. I expect my headphone socket has some damage or has become faulty.
Iv noticed that when i plug in my phone to the soundsystem i have to crank the volume up allot higher to get the same soundlevel out of the spekers as other phones. Anyone have a solution to get the volume up out of the phone? (3.5mm output)

Hissing Static Sound coming from speakers and headphones

As you can tell form the title, I've been getting a very subtle hissing static sound coming from the speakers and headphones. I've noticed it for a while now, but I never really thought of it as a huge issue, but knowing that this is a audio oriented device, this shouldn't be a problem. It's only noticeable when audio gets quite during a part of a song like a quite instrumental part of a song. When something that's very "full" is playing, the audio overpowers this static sound and isn't that noticeable. Dolby only makes the static louder because of its volume boosting equalizer.
Is anyone else getting this problem and is there a fix to this? I saw someone post about this on the zte forums, but nobody really has a solution and it doesn't seem like one that people really care about.

I'm also experiencing something similar. If I just play a song or another piece of audio clip, and then stop or let it finish playing. I can noticing subtle hissing sound coming from the speakers. It's not audible unless i place the phone almost at my eat. So not sure what it could be or if it's something to be concerned about.
I have it as well.
As was said, I have to really put my ear to the speaker to hear it.
I also have it in phone conversations.
It's not a HUGE deal. But it does annoy me very much considering that this is supposed to be an AUDIO oriented device.
I don't have it when using headphones.
I use bluetooth headphones, so never heard it.
But I do hear it now that I checked. Wonder what that is.
Hi,is that A2017U or A2017 G?
I'm getting ready to finally get the Ax7, is this a hardware defect to watch for?
Same here. Turning off Dolby Atmos improves it a bit but it seems like it's always there to some extent. I hope this is not a hardware problem.
I think this is uh normal.... Two speakers loud at that. Producing a sound it's going to keep playing until the song actually hits 0. This is how some things work. Alot really. I don't mind it one bit. The "hissing" as you call it is not really there for me. Low medium or high volumes. Maybe your speakers needs to "break-in" I've played some really loud music. Don't really hear static at any level.

yeah that's because it's harder to notice with loud, multi instrumental music, it's when listening to soft, acoustic or monophonic music that it becomes distinguishable
Check out the other threads over at ZTE this is a common issue something to do with Dolby Atmos
I have the Chinese A2017 model running Oreo & have just noticed this hissing sound which can be heard at lower volumes when I keep speakers close to my ear. I don't hear any hissing sound using headphones. I wonder if it's always been there or it's a hardware/software issue. I'm probably gonna hard reset the phone to see if it goes away. Anyone could fix it?

How to solve the Hissing Noise ?

okay , we are all stuck by that obnoxious noise of earphone in our MI a1 . some say its due to bad quality earphone ( but believe me i tried good ones too ) . so i want to know whether its hardware issue or it can be fixed by software?
I strongly believe that this issue can be solved by a software update. I've seen people facing this issue even on Bluetooth headphones so it is likely that Xiaomi can fix it. All we can do for now is just wait. Im hoping for a fix as soon as possible.

I'm using some Earphones that came with a zenfone 3 and the hissing noise is there but it's not that loud and I can only really hear it when a song stops is it worse for other people because it's no where near a deal breaker for me.

To be honest this issue doesn't bother me that much, if it won't be fixed by a software update i will just buy myself new pair of earphones that dont produce aby hissing.

Same, the advantage of the phone is more than the hissing noise. Heck even the Xiaomi own In Ear Pro HD with 32ohms also got this issue.

So here you go
Go to settings - sounds - other sounds - off the touch sound
I am facing this issue with soundmagic es 150 but what all are getting wrong is that it is not a software problem. Actually our Mi A1 produces a 10 V amplification as compared to the 2V produced by normal smartphones and hence require earphone/headphone with higher impedance buy some good impedance(somewhat costly) ear/head phones and this problem will be gone.

it a bit sucks, as i bought my AT 50x with impedance of 38ohm to be able to feed them from phone / tablet ))
software update could give us at lease equalizer where you could change preamplification to battle the hissing.
on ATH50x hissing is lower compared to samsung in ears from galaxy., where it's awful..
but nothing new, this hissing was present also on Redmi Note 4 in MIUI 8+9 so i would say xiaomi sucks at audio quality in general.

Soundmagic E10C doesn't have this issue.. May be due to its 46 Ohm impedance ...

Using an impedance adaptor from Ali express solved the problem. I used the 75 ohm one.
Just search for "Impedance adapter". There is no hissing sound now.
It seems no matter what phone you pair with in ear earphones, they all hiss + cannot playback properly at very low volumes. However full size headphones have no problem.
I think its something to do with small earphones being more sensitive, there is alot of components in a phone which are close proximity to the audio components.
Anyone who says they dont notice anything is because the volume is loud enough to cover it.
You can buy impedance adapter for like 5-15 bucks, or build yourself one with let's say 60-70ohms, it is way cheaper and super easy this way. 3.5mm on Mi A1 is 10v so you need higher impedance to lower the hissing noise (reduce voltage coming to earphones).
I am using PC headphones and I almost can't hear hissing on them since they are way bigger than those small IEMs and can handle greater voltages compared to those smaller IEMs.
Sorry for the post ressurection but this is all a matter of the Preamp being so great on the "Mi A1" that low-impedance headphones won't just cope "with all that juice". I myself was being driven nuts with all the hissing on my 23Ohm CX300 Sennheiser in-ear phones that only after reading a reddit post on this subject and finally connecting my 300-Ohm Sennheiser HD580 did I notice not only the hissing was gone for good, but also that by using the fantastic settings enabled by a simple, free app called Precise Volume, my HD580 were brought new portable life that no other DAP before it could provide it with!
