Very bad sound quality via earphones - Xiaomi Mi Mix 2S Questions & Answers

Hi, I using Mix 2s and the quality of sound on earphones is quite a disaster.
Sound is very grainy and there is a lot of static noise in some songs. I am using Spotify Premium with very high-quality settings and the sound on wireless and wired earphones is the same - means very bad. So, it’s not just bad piece of set.
I was blaming the audio codec on Bluetooth as my BT earphones should be able to use ACC codec, but there is just SBC available in developer option. I heard the BT codec issue in last Global MIUI I am using global 10.2.2) not allowing to use any codec outside SBC, but the sound is the same on wired earphones.
Does anyone experience the same issue with sound quality?

I have no issues on LineageOS (wired and BT LDAC).

I am using 10.2.2 stable too and i do not have any troubles with sound quality. Using spotify, sound is fine with Bluetooth and wired phones.

Thank you, and are you able to connect to BT headseat with any other codec then SBC? I am able to change that in developer option but it always go back to default after leaving menu.

Have tried Mix2s with 3 different phones at home on BT and headset. Samsung A8, Honor 8 Pro and iPhone 6s and most ****ty sound by class is from Xiaomi, which makes me very sad as this is my daily driver... will try MIUI EU if this makes any difference or sell my Xiaomi device.

I come from a redmi note 4X and dont notice any problems with it. I have a brainwavz BLU200, which supports aptx.
Maybe the phone is recognizing the headphones as a headset (for calls which utterly kills the sound quality).

Thank you, but this is not the case. The sound is bad also on wired headphones. Sound is flat, lot of static noise, missing any stage. By class worst sound from 4 phones I can find at home. I will try different USB C to 3.5 mm adapter if helps.

Ouch, I have not tried the usb adapter with my wired headphones. I'm scared to try now (ignorance is bliss?).

My LDAC headphones work well. I am afraid there's something wrong with your device and I'd recommend to have it repaired.

Just tested the wired audio with my Brainwavz HM5 and i found it awesome. Also i have searched a bit on the net and seems that the mi mix 2s outputs analog over the USB-C adapter. The sounds come from the DAC on the SoC (SD845) which seems to be a quite nice DAC (https://semiaccurate.com/2017/12/19/qualcomm-ups-audio-ante-snapdragon-845/) to be a cellphone.
Try wiping and flashing a stock rom. If that dont fix it, I suspect that your case is a hardware problem.
And last but not less important, i'm not an audiophile so maybe what i hear good is subpar to you, but if the sound would be as bad, way more people would have complained by now.

Thank you. I have tried different USB-C to 3,5mm adapter then standard Xiaomi one and grain is about 50% less so positive news here, but sound is still flat and dont have any sound stage. May be I am to picky and got luck with my previous phones. I have ordered external DAC adapter to solve this problem as on the other hand this is only problem I have with the phone.

I one of my friends found the core of the problem. He sad to have iPhone 7 that sounds ****ty as well. He had found out after about year of searching and two sets of headphones that somewhere in some different settings was set MONO sound only. My problem was same and very stupid! For my IQ deffence I don't know why this settings is not located in sound section. So problem solved and thank everybody for help! For anyone having this issue you can deactivate Mono sound in Settings -> Additional Settings -> Accessibility -> Turn off "Mono Audio"

Microsoft Surface Pro sound way to quiet

Out of all my devices that I have and have used my Surface Pro has the most quiet external speakers of them all.
Try to play a Netflix movie or show and have anything else going on around you and you won't even be able to hear it.
It's great with head phones on but I use this all the time for watching shows and movies while working out. Its so quiet I have to use headphones when I am on the treadmill or I cannot hear it playing while the treadmill is on.
I hope Microsoft addresses this on the next model.
Love my Surface Pro, it is by far the best device I have used so I can easily live with the sound issue.
If your are thinking about buying it, stop reading this, go to a store or order from their site and get one NOW.
I own a network technology company and handle IT support for a lot of companies and I can do everything on this (using it to type right now) that I could do with a full blown PC setup. I have also owned every tablet, laptop, and device that has ever come out so trust me when I say it is great.
This unit has replaced my Lenovo Yoga 13, and my Samsung Ativ 500 and 700 with no issues. I have also had every Samsung and Asus tablet and this is a bad boy. This also includes the Tab and Note series.
Hey not sure if this will help you but it works well on things that are low volume at the source.
Go to your sound settings in the control panel, go to speaker properties, then enhancements, then enable "Loudness Equalization" and click settings and set the "Release Time" to shortest.
This might actually make your videos sound worse through headphones but when using the external speakers it normalizes the volume so that extremely low sounds are louder and extremely loud sounds are softer.
Also this might not work well with applications that have built-in sound normalization like MPC-HC so you might want to only enable it when you're watching netflix or youtube or other flash based media that doesn't have built in normalization.
IMO the sound's loud enough, louder than all my tablets and my old dell laptop. But definitely softer than my brother's MSI gaming laptop.
RT is the same. Bummer, but oh well. I use a Belkin bluetooth receiver with my old computer speakers, works GREAT! :good:

You sir.. where do I send beer money.. My Surface is finally louder than a mute mouse.. YAY
For what it's worth, if you have an original Surface Pro or the Pro 2, you may be able to use Ears (https://www.kickstarter.com/projects/1463948377/ears-for-the-surface-tablets). They're not on sale yet (and the Kickstarter project has ended) but they should be available for purchase after the KS backers receive theirs.
I don't know if the Surface Pro 3 will be supported though.
You ROCK!!! Thank you so much!
Thank you so much! You have no idea how much grief that has caused. That is something that has driven me crazy since the day I got my Surface! Now I love my Surface
The same would go for the (new) Microsoft Surface Pro 3 as well. The sound is truly NOT loud enough at its max volume and "loudness" setting.
Solution:
- Get a portable USB headphone DAC amp like the FiiO E18 or something comparable for your SP3 and/or phone/mp3 player that's smaller if a smaller size is your forte.
FYI:
I always use my Shure SE846 IEM's for earphones with my SP3 and phone... as they will blow your mind to smithereens. At $1000 retail, I expected nonetheless and I was highly pleased when I upgraded from the Shure SE215 earphones to these professional-grade IEM's. Before buying my SE846's, I read at www.head-fi.org that these IEM's NEED an external amp I bought the Fiio E18 Kunlun. After listening to the same songs WITH the FiiO USB DAC amp... I was truly dumbfounded. At times, when using my SP3 with the Fii0 amp I have to turn the volume down at the start of some songs because it gives me a headache from some of the songs being a little bit too bass heavy. So to whoever reads this... pass along the info to everyone you know with tablets, home theater systems (with separate receivers), laptops, desktops, and ALL versions of the Microsoft Surface tablets that you WILL NEED an external USB amp! DAC amps are technically better but a regular USB-powered or external portable built-in rechargeable earphone amp will work. The FiiO E18 gives me like 16 hours of hi-fi music when fully charged too.
Worked for me +++++

USB Audio for TF700

Hi,
I've been looking for a solution to use a dedicated USB soundcard with my TF700, because the sound quality from the 3,5mm analog out isn't loud enough, the quality isn't great and I hear lots of intermittent "hiss" noises when I'm watching movies with DTS sound (whatever the video player I use).
The main problem is the loudness, since I'd like to use the tablet to watch videos i.e. in a plane.
I was thinking of an external USB soundcard like the Asus Xonar U1 or U3 to connect to the dock's USB, but I'd like to know if anyone has tried it before.
Preferably, I'd like something with a dedicated headphone amp.
I have a HiFimeDIY Sabre DAC that kind of works when I plug it in the dock, I hear sounds but with lots of popping and cracking.
Using the USB Audio Player I could make the tablet work correctly with the DAC, but that one only works for music, and their custom driver doesn't work with other apps.
Any help?
(sorry if I posted in the wrong section)
An update:
I went to a store and tried a Xonar U3 connected to a TF700+dock. Same thing as with the Sabre DAC I tried earlier.
Whenever I play something, the sound is "recognizable", but it's mostly made of popping and cracking.
It sounds the same as is I was used the Audio Player before applying the proper settings (force 1-bit, 16bit sampling, 4k buffer).
This seems to be a driver issue. I heard Samsung phones/tablets work flawlessly with most external USB DACs, so this is a real shame.

Bluetooth audio streaming quality poor?

So i noticed a severe decline in the music quality after i switched from my Z3 compact. Using Poweramp with all the EQ's disabled/flat (and all the samsung eq's off), i get constant minor treble crackling. Full volume and even half volume on the phone. It's really annoying. I have certain songs on my computer and Z3 that i've played so much that i know exactly how they should sound, and the S7 just makes it sound like ****. Has anybody else had this issue?
Do you have any other bluetooth devices connected to your S7, such as a Fitbit or Android Wear watch?
I'm using BT streaming to both my Sennheiser headphones and to my car, and have not noticed any worse sound quality compared to my previous S5.

I suffer with the same issue on my S6 and was hoping they'd fix it on the S7 but guess they don't care.
Thread about it for the S6: http://forum.xda-developers.com/galaxy-s6/help/poor-bluetooth-audio-quality-t3093236
TL;DR, If you disconnect the Pebble your bluetooth audio quality should be good.

I also use two headphones that do not have aptX, but they sound perfect too.
after tuning off the bluetooth to my pebble and rebooting the phone, the sound came out fine through my ford sync stereo. i might as well use an aux cable to remedy this $700 phone's issue.
FWIW, there are two less intense ways to "refresh" the bluetooth audio connection:
1) Toggle the phone's bluetooth off and on.
2) (New to Marshmallow touchwiz) Bring down the notifications and you'll see "Audio path" on the right. Switch it and switch it back to the bluetooth output.
Thanks for the info everyone. I just upgraded from the s5 to the s7 and noticed a significant degrade in blue tooth audio streaming with my Ford sync system. Really upset me so a little Google search and discover.my moto 360 watch is the culprit. After I disconnect it my sound quality goes back to normal. Certainly a pain but at least it's resolved.

I have 2016 Lexus ES350 and I have recently started using Garmin Vivoactive HR+ fitness tracker that is connected via Bluetooth to my Samsung Galaxy S7. The bluetooth streaming quality dropped significantly. All music sounds flat even when the music player (Amazon Music) is set to highest quality. In rock music I barely hear hihats. High frequencies are distorted.
Are we supposed to go back to the auxiliary audio input jack again? What's up with this?
Thats because sony always use high quailty DAC's and sammy doesn't. same reason why sammy cant play high res audio.

I'm using S7 edge with viper4android and connect to my car bose system the sound looks amazing. ALso I use it with a audio-technica mx-50 and portable amplifier. with bluetooth I don't notice any issue, because mainly I connect to amplified sources. <With direct connection to the mx50 headphones definitly could be better, but I wouldn't say is really bad. I use flac and sometimes spotify in extreme quality.

Hi the same here, i had a HTC onex/onex+ and the last a LG G3 , the audio was fine when streaming mp3's from my phone, now with my brand new Galaxy S7,
there's so much distorsion that it's not earable, my car is Lexus CT200h(no navigation screen panasonic audio) , worse with waze or google maps i cant anymore ear vocal instructions for navigation except when streaming audio or during a phone call , not anymore when listening a cd in the carplayer as it used to be with all previous 3 phones
ps: i think there should be a "bluetooth" section in the real life thread , i dont know who is in charge of that sections,
i will put 1 star to bluetooth and audio listening and 1 star for audio when recording videos in Gigs i wouldnt buy the S7 if i knew that before

What is the sound quality when using Bluetooth headset?

I found some noises when I use Bluetooth headset with aptx feature, when I use Bluetooth headset without aptx the sound quality is better, anyone face this problem?
The sound quality in my cars built in is great. Dont know if this helps...
Dose your car have aptx?

I originally wrote this which is wrong
I am fairly sure the AZf3U doesn't have AptX... I've not found single Snapdragon 650 or 652 with it
even though Qualcomm own AptX/Aptx-HD now.

Since then I did some research, and found I was wrong. So I came here to correct my post, and noticed that @tamerh had thankfully pointed out the error before other people were misled.
So I found that there are products with the Snapdragon 652 which do have AptX, and not only that, the Asus Zenpad 3 8", has an SD650 and AptX.
https://www.asus.com/Tablets/ASUS-ZenPad-3-8-0-Z581KL/specifications/
It occurs to me that there may be apps on that tablet, as well as patches and updates, which can be applied onto the Zf3U, and vice versa, as there's likely to be a fair in common between the devices.
Asus zenfone 3 ultra has aptx, the aptx notification appears when I connect a Bluetooth headset with aptx, and asus zenfone 3 ultra comes with snapdragon 652

Question Is Bluetooth Codec, Apt-X HD and Adaptive available ?

Hi, can you tell if bluetooth codecs like Aptx hd and aptx adaptive from the developers options menu were added ?
LDAC, SSC, SBC, AAC and AptX are present.
AptX HD is likely not supported. Never has been.
Well, it sucks.
The Buds+ (SSC) are excellent for calls, and very good for music using Poweramp's graphic equalizer. Double as noise plugs. Very long battery life.
A LDAC headet from Sony or Panasonic be the next step up.
All are inferior to a hardwired headset.
Samsung had room for the 3.5mm jack and the damn SD card slot.
It's netted them a lot of lost sales from me. I now have 2 N10+'s and don't intend to buy any new smartphone for 2-3 years.
Other than battery replacements the N10+ can easily last 3+ years. This one I'm using is 2.5 yo, in mint condition with one battery replacement.
Still running on Pie, current load will be 2 yo in June, still fast and stable with minimal maintenance. Security is simply not an issue.
The N10+'s color rendering index and white point exceed the newer variable refresh rate displays.
It gets 10 hours battery life. It's still a blast to use which is why I got a backup one... whatever
"Samsung should add the aptX HD, aptX Adaptive and aptX TWS+ Bluetooth audio codecs to their line of Galaxy S products."
Sign the Petition
All aptX Bluetooth audio codecs on Samsung Galaxy S devices
www.change.org
You should care people, because there's no more Jack 3.5mm...
Bluetooth on this phone is trash
The last time we had AptX HD was during the S8 plus with Oreo.
They supported the Level Headphones with UHD and AptX HD.
Then when Pie came, they discontinued the headphones and they removed AptX HD.
People with such headphones made petitions in the Samsung community forums and samsung finally resurrected the AptX in the Note9. During this time, samsung pushed the Samsung scalable codec for all the new wireless headphones and true wireless headphones.
But dont expect samsung to bring anything back, they are now supporting their own codec and devices. Still LDAC works well.

You're totally wrong, it sounds even better via BT than wire for most of BT headphones because they use their own DAC. The KBPS does not make everything, If you have at least 500 KBPS is way enough for sound quality, most important is DAC and of course the Headphone itself.
Boom player, neutron, poweramp or stock samsung music player. And for best sound you need best earphone (bragi dash pro)I use.

U'd better study a little...
All BT codecs are compressed (even aptx HD) and lossy and cannot reach HiRes quality. If u listen to Spotify of course you're already using a very bad source.

Damn you understood nothing, what I said ?, Which sound better between listening 320Kbps MP3 in a AUDI A8 with Bang&Olufsen audio system and a wired JBL headphone with MASTER TIDAL 24 bits music etc... Can you answer which is the best experienced, after you can tell me u'd better study a lot.
Depends on how u connect headphones to smartphone, if dac of the dongle kn MQA certified (oh and btw MQA is compressed a d lossy)... There is no BT that is bit perfect, and if u listen to mp3 quality the codec is insignificant... even if you listen to Cd quality, since no bt codec can match...
U can have the best dac in the world, but garbage in garbage out... Take a 24bit 192KHz FLAC and play it via aptx hd and your hear trash... play it via any other bt codec a d you hear slightly worst trash... it's still trash so why care?
