Mi9T Has terrible audio quality & mic ! - Redmi K20 / Xiaomi Mi 9T Questions & Answers

It like all the audio inputs/outputs on this phone are just terrible, The mic is really low quality and the playback from it is really low almost inaudible at normal volume. The speaker also sounds really distorted and bad even the headphone jack is low quality though turning on Hi-Fi audio from the settings seemed to slightly improve it.
I'll soon try a USB-C headphone and report the results.

I would have to disagree. I've been using this phone for about a month or so. It's not better or worse than the Note 8 that it replaced.

It's working fine to me, even ear speaker it's loud to me.

I have the same problem, even with the maximum volume on call, you can't hear well

I have to disagree with this one. I have nothing but good experience with its audio.
Everything is good on my side. Maybe you bought a defective unit.

Hello,
Any news on this? I got a Mi 9 Lite and it sounds so broken. I only got the Speaker problem but I kinda fixed it with a 3rd party equalizer. I thought that maybe with a factory reset it gets fixed but it's a hassle.
Did you do a factory reset? What's your story?

USB C headphone would be irrelevant in your case since the processing would be done by external DAC and not the phone's DAC.

Yes you are right. I mean, I fixed it with an app called equalizer FX but it's annoying that I have to have another app running in the background all the time for something that obvious. I messaged the MI team inside the settings and hopefully one day they will reach to me.

Disagree. The Audio Quality is very decent, especially through 3.5 mm jack when Hi-Fi Audio mode enabled. Yeah when not enabled, it sounds a bit thin and lack of driving power, but when enabled the audio sounds more amplified and layering improved.

Hissing/static noise everytime G1 plays sound. Both speaker and headset. Just me?

I have a noise problem, I don't think it's quite the same as previously posted noise problems.
I get a hissinh/static noise from the phones speaker (on the back) and from headphones. It is only happening while the phone plays sound (and some seconds later). Every time I up or down the sound with the volume keys, there are noise coming out of the speaker for some seconds. Please report if you have the same issue, especially eith headphones.
I could live with the speaker-noise, it's not that big a deal.. What's worse is it is in the headphones. I have a quite low impedance set of in-ear plugs from creative (I am able to hear the hard drive spinning up in my old mp3-player, but no constant noise) Crap. I want to use the phone for music listening. Question is: software or hardware related? Using JF 1.51 ADP for the record
I hope it is hardware related - I bought mine off ebay, allthoug brand new and everything, I don't know how I would go about getting it fixed/a new one with no receipt. Shipping it back and forth to England isn't really tempting either.
It's not just you, it's piss-poor rf isolation on the audio outputs. Listening with bluetooth doesn't solve the issue either as bluetooth has its own noise.
Yeah, I have yet to listen to a decent pair of BT headsets.
So this is a known problem, and it's definitely a HW issue? The fact that it's only there when sound is played, and is also there with a headset (where shielding around connectors is not and should not be a problem at ALL) made me hope this was softwar related. Argh, what to do then? The sound quality despite this seemed prety decent, although a headache today prevents me from really listening to music and say for sure. Shame.
*Pondering refund options.*
Any chance of isolating around the connector and fixing this, if it is "airborne" caused noise, or will the noice enter the equation before the connector (cabling, sound chip)?
I will try with a relatively high impedance headset (sennheiser 555) and see if it is better there. But can't take them on the bus anyway. But a couple of Ωs could always be added somewhere along the cable and might do some good. Have to have the sound at the lowest levels with the in-ears. Maybe a software fix to lower the volume output will help? Or won't it, if RF noise is the cause?
red: I will buy this item and hope it helps. And will look into lowering the volume output when using headphones as well. Should be possible (atleast it usually is with tweaks in WinMo.)

Sound distortion playing music with some headphones

I have found some strange behaviour that i'm hoping someone else can test out on their Galaxy S.
I have found that some headphones seem to work fine with the phone for music playing but others result in the sound being distorted with the vocals being very faint as if the left and right channel are cancelling each other out (with vocals generally being on left and right channel).
The packaged Samsung headphones appear to work properly although the quality seems average. I tried my iPhone headphones but these resulted in the strange sound distortion described above. I also tried a pair of cheap Sennheiser which were a free give away with a purchase from Richer Sounds and they worked well. Another pair of no-name cheap headphones exhibited the same distortion problems as the iPhone headphones.
Oddly, the FM radio sounded ok with all the headphones, it's just the music player that has the problem. I have also tried a couple of other music apps including the doubletwist player to rule out the software.
I'm considering taking it back to the shop to swap for a replacement. I'd be grateful if anyone could try out some headphones (particularly iPhone ones) on their Galaxy S and report their results to see if this is just a quirk with my phone or the Galaxy S in general.
Many Thanks
I just need some clarification because I know that a headset, and not headphones, is delivered with the Iphone. If it was a headset then I might suspect that different Iphones use different polarity as opposed to Samsung. Try out the Samsung headset on the Iphone.
EDIT:
Obviously not the problem. I must have skipped over the radio experience.
I can't post a link to it, but I remembered that GSMArena did a thorough review of the SGS. If you find your way to it, go to page 6 and see the sound chart at the bottom. SGS is superior in sound to iPhone. Perhaps the iPhone headset/headphones and the cheap ones are not sufficient for the SGS? I'm guessing
I had a similar experience when I tried to use the Samsung Spica headset on my HTC Hero. It seems that it might be a difference in polarity as suggested above.
Does all the headsets that give distorted sounds have a microphone on them? (E.g. not headphones)
the iPhone's headphones have extremely high distortion regardless of the media using to play them. The SGS is probably just overpowering them because they are very loud headphones as well/easily powered.
No it's nothing to do with them being overpowered.
I have an expensive pair of etymotic in ear headphones that are exhibiting the very same problem. Strangely I found a fix. They have a microphone on them and pressing in the answer button on them seems to fix the problem. I have taped the button down now and everything works perfectly. The second that button is released though, everything goes back to being faint, muffled and distorted.
Odd!
PS. This isn't just with the music player. I noticed it first watching a video.
It sounds like Samsung has their own way of producing the 3.5mm port with regards to the microphone support.
The Samsung headset distorts music on my HTC Hero.
The HTC headset distorts music on my gfs Galaxy Spica
To be clear, are you saying the problem only affects headsets with microphones? I have etymotic er4p headphones and it would be a deal breaker if they didn't work right with this phone.
If its only showing up in the media player, check that you havent enabled the 5.1 button in the the top right of the player. This can really screw with the sound and entire frequency ranges can be lost. I'm guessing this is whats happening.
The default headphones work fine for me if a little tinny, but with my Senheissers, the results are very pleasing. Apart from a slight gap between tracks that should seemlessly play through, I prefer using it to my iPod Touch. Being able to change tracks and volume without unlocking is a nice feature.
I threw my iPod headphones out years ago, they're the most ridiculous design ever, with the cable tapping the inside sleeve all the time when you walk or run.

It sounds like that the problem is with headsets with microphones, yes. Not sure if it happens with all 3rd party headsets w/ mic though.
Considering you have etymotic, and ClownShoes a few posts up have problems with this brand, I guess you're out of luck unless you wanna tape the answering button like he did.
The er4p is just headphones, so it sounds like i'm in luck.
Got my GS a few days ago and im having exactly the same problem with the Etymotic hf2 Headset with mic. So yeah it looks like it the mic that causes the problems.

It's a little bit crude, but taping the button down does work.
I have the same issue with with Monster Studios even with the cable without the integrated mic. Would be great to have some sort of fix.
Headphone issues
Just thought I would post what I knew about the issue, both me and my dad purchased the same pair of headphones to use on mp3 players (the headphones are ultimate ears metro fi 220 vi's if I remember correctly, these have an in-line microphone as well as a single button for answering calls and to control music playback). Whilst I experienced no distortion when using them on my iPod Classic, my Dad's Creative player would produce the issues described above - he found that either taping the button down or slightly pulling the headphones out would solve the issue however it ended up annoying him so much that he went back to using another set of headphones.
I don't know what causes the issue but I just thought I would let people know
i have some sennsihaur sport headphones which work fine no problems. i also a monster fm transmitter in the car.. again no problesm.. just make sure the volume is not on max but 1 setting below max.
Hmmmm, a few problems here. Obviously the standard Samsung headphones are fine, no humming, no background noise. However if I connect the following:
1. Standard Apple iPhone (with mic) loads of background noise, humming etc
2. Shure (no mic) loads of background noise, humming etc
3. B&O (no mic) loads of background noise, humming etc
4. Shure (with mic adaptor) loads of background noise, humming etc greatly reduced by pressing the mute key.
Using the Shure adaptor with the others resulting in the same as 4.
Needless to say I'm not happy!
That's too bad. Not being able to use my Shure with the phone renders it useless for music and that IS important.
In the SERVICE MODE *#*#197328640#*#* there is an audio menu
there you can change the headset settings too like NR noise reducion.
i did not test and changed the settings but when i had the samsung omnia2 last year
i had some problems with my headset and fix it in in the sevice menu.
when you gonne do some tests write down the orginal settings before you try.
hope this will help some of you..... and post the results
im sure its the jack, cos the galaxy s has a 4pole trrs at left/right/mic/ground
iphone compatible headset have a 4pole trrs at left/right/ground/mic
thats why pressing the mic button clears up the sound as it closes the circuit
so it a matter of finding an adaptor that switches the mic and ground terminals
I have a tf10vi and im trying to diy one
will post the results
Just saw the post and thought I would check mine again, not that I noticed anything....anyway tried few songs and different types and all are sounding amazing, I use Sure 530 so music needs to be no lower than 256 to get the best out of the phones, most of my music tracks are 320bit.

lineout audio quality

Hi guys I am new, First post.
I really enjoy almost everything about the Focus. I bought it because I was so happy with my Zune HD.
I was underwhelmed when I plugged in my Grado headphones tho. Perhaps the Zune is just very high caliber, but It seems like I am missing some lows and the soundstage seems flat. Does anyone know what sort of Hardware went into this phone? If the hardware is good, is there anything I can do software or backend to make it sound better?
I have a second complaint. When I stick a headphone jack in the mic turns off, it probably is expecting an inline mic with the headphones. My problem is when I then go to pull out my headphones the phone doesn't notice and will continue to not hear. It takes two or three times reinserting and pulling out the headphones to remidy this. Is anyone else haveing this issue.

Headphone Jack -- hissing / static / poor audio

Hey there.
Having a weird issue with my new S8. Without "UHQ Upscaler" enabled, the sound coming out of the headphone jack is bloody awful. It always has a staticy overlay, and sounds like it is coming through a tunnel or something. Even with the Upscaler enabled, I still hear this sound if Bixby is used while the phone is plugged into a jack, or from a few apps that produce audio, such as Google Assistant, Maps, and a few games.
Anybody know a fix for this? I tried to search XDA, but haven't seen anything specifically around this. Few threads on some other communities, but nothing that seems to offer a permanent solution Thanks for any help!
Maybe some effect is turned on. In the settings where you can set the uhq upscaler, there are some effects.
I had this issue too and after a search in sound settings I found the concert hall effect turned on.
I can confirm the poor and dinky sound quality. I'm a little confused und shocked how Samsung can desigend a current top phone with these audio quality.
I use my S8 with an high end AKG headphone. The sound is far too quiet very dull and imbalanced.
Also adapt sound and UHQ upscaler dont deliver a reasonable sound quality
I think the only way is to root the phone and install Viper4Andriod.
My previous phone (LG G4) is known for the sad sound quality but with Viper4Android the sound was much more better the the S8.

One of the first things I checked. Thing is, the muted sound + loud white-noise sound is ever-present if I disable UHQ upscaler, which concerns me. The only fix for the base sound issue I could find was to turn on UHQ upscaler, but this doesn't seem to work on ALL sound on the device, meaning some things default back to that white noisy sound
Not a HUGE issue, but very obnoxious. If it means anything to anybody, I am using an unlocked Snapdragon S8. I have had this issue since I got it out of the box, so it can be confirmed the issue isn't due to a change I made or an installation I did. It is apparently not an isolated issue, and UHQ fixes it in about 90% of cases, so I suspect the issue isn't in the hardware, either

Anonaru said it's not a HUGE issue, but it is with me. A PHONE, which is an AUDIO DEVICE, shout NOT make annoying noise. Samsung brags about all these features and they can't even make the audio work. That's like an airline telling you, well our airplane can't fly but we have a new seat recliner feature!

Its just the reality of audio in a phone, but this only happens only with In Ear earphones. They are more sensitive to the various electrical interferences coming from the various components of your phone. Use full size headphones and you won't hear any interference.

Did they lower the headphone volume on latest update?

I feel my headphones sound significantly lower on latest January update.
Did anyone else notice this? Did they do it to deal with the "hissing" issue some people had?

I'm on the latest build. The hissing is for me gone (or so quiet I don't here it anymore. At about volume 1 or 2 you maybe be able to here some. But like I said, to quiet to notice and only when you play something without sound ) I think it got quiter, but still damn loud on max. I love it.

Of course it's not "damn loud" anymore, it's significantly lower and not enough loud.
Does anyone know a way to being back the old audio output on headphones?

Maybe the build in equalizer could help you? You can easily access it through google play music settings..
Maybe its your phone? Or your headphones? When I'm on max I can literally use my headphones as speakers...
There is a new headphones audio menu with Oreo.
Configuration > Sound > headphones and audio effects.
There are some headphone presets, some are louder than others.

Maybe that to. Personally I didn't notice a big difference change those settings. It could also be your music player. SoundCloud for example can't be equalized through normal ways.
Hissing is still there, maybe a tiny bit lower. Max volume is still "damn loud", my max comfortable listening level (without ear bleeding) is not more than 50%. I often listen at volume 1 or 2 (out of 30).
Both earphone volume and loud speaker volume have been reduced for me.

Well, personally, I think that the speaker sucks, quiet or loud. I never use it. I really bought the phone for its "rare" headphone jack, which since the latest update is wonderful. Maybe headphone hisses a little bit, maybe they cancelled the Oreo update ( I believe) and maybe the speaker are horrible. But it's the best you can get with almost fully stock Android and a headphone jack.
Yes I wrote to much
Yes, I noticed this too...
I noticed this too as the volume that I used to play music at (about 60%) with my headphones was MUCH to soft after the update! Something definitely lowered the volume, though it SEEMS that it is more on headphones than the speaker. I have to go to max when on headphones to listen to music now. I say 'seems' because I don't use the speaker for much more than phone calls, and while it is quieter, it is not so quiet you cannot hear the conversation. It would be nice if there was a way to get the volume back, but I'm not going to hold my breath.

Xiaomi Mi In-Ear Headphones Pro HD that I got a deal on when I bought the A1. They are ok... not great, but ok for what I paid for them.
I've tried multiple headphones since the update, and the volume issue is true across the board with anything plugged into the headphone jack. I have NOT tried bluetooth headphones as I don't keep bluetooth enabled.
My wife's red A1, which is still on Nougat, is much louder than my A1 on Oreo, update 1. (still haven't gotten the latest one)

maybe they lowered to power of the DAC because everyone was moaning about a tiny hissing noise, the only way to stop it is to buy more powerful headphone or lower the DAC, now its quieter we cant have it both ways guys

I honestly can't imagine listening to any of my IEMs at max volume. I can't get comfortably over 50% while commuting (bus, train etc). In quiet environment my volume's somewhere between ~3% and 16%. I would accept further lowering of overall volume to remove the hissing noise in a blink of an eye (and hopefully I'll be able to do that with custom kernel)

I've never noticed the hissing noise people talk about so much, but then, my ears are old so it may be that. Before the Oreo update, a tick over half was plenty loud. After, I had to raise it, a lot. Some songs require max, while most are ok at around 85-90%. So yeah, there was a huge reduction in sound volume on my phone with the update. At least, I THINK it was the update. I installed a Sony app to record sound. I've only owned one Sony phone, an Experia 3Z. The sound on that phone was horrible. Even at max volume, you could not hear it ring if it was in your pocket, and music was always not loud enough on headphones. I may uninstall that app and see if the volume level returns just to be sure it wasn't the app and not the update, but doubt the app would affect the whole system.
I feel that too that they reduced the volume for the audio out put via 3.5 mm jack.
I got update today, and can't really tell if there is any difference in volume. I still use no more than 30-40% of volume (my head would explode with MAX), and there is still some hissing.
This applies to Oreo patch 1. Patch 2 arrived today but I have not installed it yet.:
I am not sure what I did (or what I did that made the difference) but I deleted the Sony app, then went into the settings on my music app and did some tweaking on the modes there, and the volume is now louder than it was. I can set the volume to about 55-60% now and it is loud enough. A few songs in my library still need higher settings, but I am assuming that is because they are pretty old, converted to .mp3 files from CD's (remember those?) way back in the late 1990s/early 2000s.
Bottom line: I am not sure that the update really hurt sound volume. It could have been a combo of app differences with the update. Still no hissing that I can hear.
Regards,
--KB
EDIT: I just did the new Oreo update (89MB) and the sound was different again. I went into my music app and changed the EQ to Flat and the sound was much better. I did not hear any hissing, even with classical music, but again, old ears may be the issue there.
