[Redmi K20 / Xiaomi Mi 9T Questions & Answers] GedeonTaylor:
Hello, I have used the mi a1 then switched to mi a2, after seeing the mi a3 I chose the mi 9t over it. The difference you will face after using the mi 9t over the a1, the 9t has a bit lower quality haptic motor, but after the mi a2 the headphone and sound quality over all is the same = good. The mi a2's sound was better than the a1 I remember, that means the 9t has better sound quality too.

I hope my english is not too messy and you can understand. :)
[Redmi K20 / Xiaomi Mi 9T Questions & Answers] 2VA:
In my opinion, the 9T offers a bad sound. That is, it is quite loud, but it is tiring because of the underlined upper middle and high with a certain lack of information in the voice range and bass. This is a sharp and unbalanced sound. I can compare it with Redmi Note 4 and 7 and to my taste old phones sound better despite the lower resolution. Compare with Galaxy Note 5 or Sony NWZ-A15 does not even make sense, alas. No claim to the ultimate truth, just my opinion.

PS

I use Sony A3, A1 and different Momentum models, I never use an equalizer and I consider Neutron the best software player.

But that's just work with cable not Bluetooth right?
[Redmi K20 / Xiaomi Mi 9T Questions & Answers] Leong428:
Yes, it ONLY works with wired earphones (the option is greyed out for wireless Bluetooth audio)
[Redmi K20 / Xiaomi Mi 9T Questions & Answers] razielmcr:
Yeah, it doesn't makes sense for Bluetooth, the chip it's super related to the headphone amp.
[Redmi K20 / Xiaomi Mi 9T Questions & Answers] mik9:
Hi guys, no offense but anyone expecting audiophile quality from any smartphone does not know much about it. So let us just stay reasonable without expecting impossible. Mi 9T has decent sound, more than enough for MP3s and various online music services. I tested it with with AKG K701 (considered as reference or "lab" headphones for its flat characteristics) and foobar2000 player, using FLAC and MP3 128-320kbps. Surely, for FLAC and MP3 with higher bitrate you can find it is not perfect but the same applies for computer integrated audio cards, etc. Those devices are just not able to drive headphones properly. So, what can you do to get better sound?

1. Get proper audio device, not smartphone, for music :)

2. Try several headphones and choose the ones that will best suit your phone.

3. Use USB OTG and connect your phones via quality sound card (in the best case including headphone amplifier). I am not sure if possible currently for Mi 9T, as I tried one and it did not work (EU ROM 9.8.15).

4. Do not be so afraid of equalizing. I personally prefer to have audio chain without a need of EQ but it is nothing wrong in this case to use it to compensate for characteristics of your headphones and the phone. Equalization is present in whole audio recording chain, from single instrument recordings to mixing and mastering so it is not necessary to call it devil if it is used reasonably in playback chain. Of course, you will need different settings for various headphones.

5. If you want at least something close to hifi, forget about bluetooth :)

Happy listening.
[Redmi K20 / Xiaomi Mi 9T Questions & Answers] 2VA:
After reading such optimistic reviews, I decided to buy 9T, but I refused it after 3 days and returned to Redmi Note 7, could not stand it.

And with all due respect, it is difficult to find more inappropriate headphones for evaluating the sound quality of the phone than the K701 (I have).

PS

The peculiarity of this particular amplification path is that at a different volume level it offers different frequency response, i.e. no universal equalizer setting, alas. Well, some do not even distinguish between red and green, maybe 9T is a great option for some ears.

I do not call for discussion, but I want those who care about the sound to the headphones to be warned. Good luck.
[Redmi K20 / Xiaomi Mi 9T Questions & Answers] cacio_confusa:
I bought 9T Pro 8/256 and the headphone jack output is "ok". My old OnePlus 3 was better, at least the amplifier. Mi 9T Pro does have a dedicated DAC, but the output volume is low, so my guess is, that the headphone amplifier in 9T Pro is the bottleneck. Not enough power and possibly "eating" some of the details from the DAC.

I use rather my TWS headphones on the go. For more "critical" listening I take my ES9018K2M USB DAC.

So the headphone jack in 9T Pro is just ok. Probably enough for the mainstream, compressed music ... But for me useless ...
[Redmi K20 / Xiaomi Mi 9T Questions & Answers] nexflatline:
You connected the K701 directly in the mi9t without any external amplifier? :eek:

Does the phone even have enough power to drive that? :confused:

I tried with an Audio Technica ath-A700x and the sound was ok but not really great. And I think the K701 is even more demanding...
[Redmi K20 / Xiaomi Mi 9T Questions & Answers] mik9:
I was able to listen at my usual level at about 3/4 of the audio fader. As I cherish my ears I listen at decent audio levels. However, as I mentioned earlier, the sound is decent, not perfect on them and partly it could be because of the impedance. I used them to get reference. I understand that most people will listen on less quality headphones with far from flat characteristics and with different impedance. But it would be necessary to review the sound using dozens of various headphones and still be highly subjective.

If someone wants to use the phone as main or major listening device (I discourage you from this anyway if you want high quality audio) the right approach is the same as for all purchases of audio equipment: go to the showroom with your own headphones and songs and try the phones in question by listening to them. This final phase of purchase cannot be done just by getting info on the internet. Alternatively, you can buy and return few phones but I do not see this as an efficient method.

Btw, I was able to test the sound via USB OTG with simple USB audio interface and the sound was better. As I do not have any reference for this interface I cannot say which of the still present imperfections were due to the phone and which due to interface.

[Redmi K20 / Xiaomi Mi 9T Questions & Answers] sanoayyk:
Here is no audible noise with headphone jack. Nothing can be better and it is the best.

You can install Viper4, James DSP or Dolby to use great equalizers.

Equalizer and some audio effects can turn a chap earphone into a gorgeous one.

Without equalizer adjust, it is like you listening to an orchestra through a wall. When equalizer is tuned, it is like you listening to it from BETWEEN instrumentalists.

Nothing to say great earphones get even greater.

Some of these audio mods can take effect over USB dac and bluetooth.

So go ahead to find your best mod and settings.

Well, at least MIUI stock equalizer is poor like any "non root equalizers".

When I pull up gain of one band, the sounds from others obviously decrease. It's hard to reach the best config.

Did you guys have a chance to compare these mods with audio output of a decent DAC/player with a pair of decent headphones? I just don't believe something like this could improve a crappy hardware...

[Redmi K20 / Xiaomi Mi 9T Questions & Answers] sanoayyk:
Sorry that I didn't tried extra dac but I still need a equalizer even with such good hardware.

High performance devices mean high resolution, that is actually the higher the better, but personal preference is related more with "color balance and contrast". Everyone had a different preference so it only can be tuned personally for each one.

Therefore I think subjective audio experience is

Good HW manually tuned > Poor HW manually tuned > Good HW untuned >Poor HW untuned.

Just like an 4K movie with terrible color can be less dynamic than a HD movie with vivid color.

I dont have externel amp or dac like jds atom,thx 789, fiio btr5k etc etc. I m using sennheiser hd58x with mi 9t and for me its really good but not enough for me. i dont know why but musics cracks when i max out the volume

So how does 58x sounds on mi 9t? its EXTREMELY clean, seperation is nice (but i need more), imaging is nice (need more) soundstage is, well they are close i think (no idea on soundstage tbh) basses are a bit distorted on high volumes (send me a music with bass so i can test it more) mids are nuts, just so gooood melts your brain (maybe because its hd58x) treble sometimes at the edge sometimes crosses edge just a little bit for me (specially on high volumes)

if i have to explain imaging : i listen phil collins in the air tonight and the drum play on 3.40 starts left to right nice but accuracy drops when phil hits drums on the middle.

seperation: i had some ideas about layers in the music but with 9t layers are clear enough to be heared. lorde - yellow flicker beat is the best example for me (starts 1:22 ends 1:28 ish another one starts at 1:34 ends at 1:38) if this is a different thing please inform me.

i have acer nitro 5 laptop and mi 9t is CLEAR upgrade to nitro 5, i think the shocking clarity is incredible i m sure non music maniacs will like it but if you are a music maniac like me you will want more anyway.

still this phone have excellent value, premium looking and quality music is a nice addon
[Redmi K20 / Xiaomi Mi 9T Questions & Answers] JUSTICEFORALL:
Possibly my first post @ xda, as I could not resist it.

HiFi audio in 9T Pro is basically using the QC (Golden Ear approved...or something similar) DAC.

Obviously it won't work with BT headphones ( I honestly expected xda members to know that BT headphones use their inbuilt DAC-Amp section to produce sound for obvious reason, BT can not transmit analog sound signal!!!)

And in wired mode, it does work VERY well. The volume may sound a little lower as once you are enabling the HiFi audio, it is disabling the hidden compressor of MiUi EQs.

Hope some of you have noticed that in stock ROM, it is not possible to turn on both HiFi and MiUi sound effects simultaneously (obviously a single DAC chip can not work in both low and high energy mode simultaneously or dual DACs -assuming it has the onboard default SD855 audio chip. Yes, dual DAC can work, but that is extremely complex and I am pretty sure Xiaomi did not give us that)

Now in custom AOSP based ROMs things are really messed up. Here you can not enable hifi audio without turning on MiUi enhancers...and all custom ROMs do suck in sound quality with wired audio (basically we are not getting the better DAC mode and developers are covering it up with another software EQ and calling it HiFi audio...sad indeed...

Please for heaven's sake do not use the weird AKG 701 to assess quality of a phone. My FiiO M11 pro struggles to bring up lower frequencies from it.

TLDR: 9T Pro has excellent sound quality (wired) and it can easily power upto 100 ohms cans easily and all IEMs perfectly. It is miles better than all previous Xiaomi phones I've tried. AND YOU ARE LOOSING OUT ON AUDIO QUALITY WITH AOSP BASED ROMs.

I know nothing about Android development, but working part time in audio production for decades.

Peace.

Unfortunately, that's extremely unlikely. If it's a Verizon version - of most, if not all phones - then bootloader/root is out of the question.

On top of that, doesn't seem like there's much attention from devs for the Moto Z line as a whole, so an unofficial unlock is also extremely unlikely.

Only options are wait for Verizon to stop being jerks, wait for someone to come up with a way to unlock their version, or return it and get the unlocked version.
