Bluetooth Music Quality - ZTE Axon 7 Questions & Answers

How the does bluetooth sound for you guys? Mine seems to be worse after the B29 update (not for certain that's when it degraded). I have a decent car stereo setup, but bluetooth distorts and crackles in the mids and highs. It's not unlistenable, but I thought my stereo was on the fritz until I used my 3.5mm input from the headphone jack, which sounds just fine. It can't be that the DAC is that much better, as my other phones sounds fine and this used to.
Do you have any thoughts or experience with something besides a small bluetooth speaker?

And I have tried playing with the Dolby settings. They make no difference with the distortion.

After some perfunctory tests I have noted that Bluetooth audio seems to introduce a significant amount of extra noise at high volumes. Aside from the additional background noise I have not noticed distortions with Bluetooth yet. I have only checked this on B29.

Just something to try...I have a BT device hooked to my AVR, and when I stream through that, if I have the volume on my phone up it sounds horrible. If I stream through it with the volume up just 1 click of the volume button, it sounds good. I increase volume at the AVR instead of the phone.

Through Bluetooth hands free working flawlessly to my.(A2017G version)
I'm having 2 LG 1100/2 Sony SBH 80 and 2 SBH 20.
Haven't try it with external speakers(since I don't own any kind) and on my car I'm using the handsfree and not connected to the car audio system.

I have a A2017G on B05 and a somewhat cheap aukey BT headset: it seems to sound fine for me, no crackling or hissing. Have you tried it on different devices to compare?

A2017U on B29, using Jaybirds Bluebuds X, the sound its great, no distortion or cracking.
I use the Bluetooth on my car stereo too and the sound is excellent. No dolby, but the equalizer works fine.

Did you verify that all your bluetooth devices supports aptx? if not then you will lose sound quality :S
idk, i dont like bluetooth audio streaming... even with aptx. Its not bad but if you want to steam flac music it will still limit the quality. Somehow if i stream the music via bluetooths aptx it sound flat not dynmic and
voluminous.

I haven't tried it with the volume just below full. I'll give it a shot in the morning on my commute.
Other devices (S5 and 6P) sound just fine when paired to my headed unit, so it's likely something with my Axon 7.
-----
Quick test with the volume just under full seemed better. I'll know more after a drive tomorrow. Thanks everyone.

EQ on on your car stereo or phone? I don't know of an EQ on the phone (maybe I've overlooked something).

On the phone. I meant to say that it's not using the HiFi audio, but the Dolby eq it's fine on Bluetooth. Sorry for the confusion.

I think it sounds about 95% better just one click below full volume. I never would have thought that digital Bluetooth volume would have been the problem, having always set it to 100% with every other device. Thankfully, Tasker makes for a quick fix.
Thanks for the tips and feedback, everyone.

final conclusion the sound quality from the touch hd really really sucks

Ok well I went thru many testing options when it came to the sound quality out of the touch hd compared to other devices.
1- to test the sound quality I used the following players
a- core player 1.3
b- pocket music 5.1
c- touch flo player that came with the htc
d- pocket player
and all sucked big time, when I connected the device to a sony adapter cassette in the car. The sound is really awful comapred to all the devices I own like the iphone, or ipaq. WHAT THE HELL IS THE PROBLEM. I tried to use the equalizers in all the palyers, aslo the audio booster but the sound sucks. I tried to use also an adapter that has 3 rings on it to connect to the htc hd.
Please am I missing something here???

It all comes down to how you have your HD setup. First, check the app called "Audio Booster", it comes out of the box configured to sound like ****, turn it off. Get the HD Tweak app and disable the 100db sound cut barrier and use the graphics equalizer that is in your chosen player. I use Mortplayer and now I can say that the playback with my Sony in ear headphones is really good.
HD Tweak has a setting that should reduce the ring delay.
me I also agree that audio booster sucks, when switched off sound gets much better
Also, a cassette adaptor is likely to limit the quality you can achieve. Better to compare through a decent set of headphones.
Seriously man, putting that line in your topic title is misleading.
I've tested Touch HD's sound on high quality headphones (Ultimate ears Super.fi 5XB) and the sound is great even on stock settings. In fact, my iPod is getting a lot less playtime since I bought THD.
Did you notice any hiss in qiet moments or on gaps between tracks? For me that is exactly the same as it was on Kaiser
Yes I noticed a hiss and a small gap in a song, i even installed the hd tweak, and sd tune up. But still the problem remains.
I am not talking about using it with headphone, I am talking about using it on my car stereo, thru a sony cassette adapter. Aren't we all in need for a great sound in the car, and why all the other devices sound great on my car stereo except the hd
I only have Shure E2C for "in move" devices, but I remember them sound much better than with Touch HD

I'm having similar troubles here! Turning down the volume to about 30% on phone and using car stereo volume helps a bit. Also try different players and get rid of the car charger! It truly sucks as my other ppcs & mp3 players do not need tweaking AT ALL! They all play & charge at the same time.

Is this a joke? Sorry I am confused. You are talking about the needed GREAT SOUND an than you are talking about some funny CASSETTE ADAPTER?
Conclusion: If you want great sound in your car, you should not spend all your money for a phone - How about new car stereo - some of these funny new toys supporting funny things like LINE IN or USB-MP3 or Bluetooth A2DP / AVRCP (handsfree profile). I had a really hard time to remember how a cassette looks like.
The next one blames HTC becauese the HD doesn´t sound good when connected to the phono-in of his late ´80s stereo.
From my point of view, the HD serves a better quality as most of my "old" mp3 Players, better than my iPod but not as good as my MP3 from Philips. Even so, yes i´ve noticed these short lagggggs in playback. I wouldn´t have noticed them if someone here hadn´t mentioned them.... so thank you
What´s next? 8-track tape adapter doesnt work right on your high end car stereo?

My Kaiser didn't had any... But in the HD I notice it happens once in awhile using bluetooth phones. But in general i got tell the SOUND ROCKS.... (after you used HDtweak to disable the 100dB limit!)
The title is really misleading for a new costumer, it's not true that the sound output sucks in my tests it resulted better than my old n95 8gb and an ipod touch.
For the average costumer the sound output on headphones is good.

If you are noticing differences between devices when using the tape adaptor in the car but not when using headphones, there has to be something different in the setup. (Or you're using apple-grade headphones )
The tape adaptor is designed to mimic the response of headphones, so that the player doesn't see a difference. I second the suggestions of turning off the audio booster and 100 dB cutoff, as these can and often will interfere with the signal.
Once you've turned off the equalisers, try setting the volume on the player to about 50 - 70% and then adjust the car stereo to your required volume. There may be a mismatch when the HD amp is either running at really low or high outputs, causing distortion.
It would also be helpful if you could characterise the type of problem you're having: Hiss, low level overall distortion, distortion mainly on peaks, poor frequency response, etc. Different effects will typically have different sources.
NB: don't rubbish the tape adaptor! It serves its automotive function for me as well, although I'll take my Grados and Westones when the wife isn't in the car
Edit: Just did a quick comparison with my iPod Nano and there is very little between them on good headphones.
I can't confirm that at all, using Koss Porta Pro headphones and Coreplayer for playback (audio booster off, 100 db limit disabled, equalizer enabled) I get fantastic sound for a portable device, something's wrong with your setup.
Just connected my HD to my Z-5500 500W sound system using the analogue connections. It sounds perfectly fine to me, as good as anything else analogue i have connected.
I'm using my Touch HD with a pair of Sennheiser HD550 and some BOSE Quietcomfort 2 headphones. By no means super high-end, but good enough that I can say that the sound on my Touch HD is very good. No hiss at all, good clarity and overall good sound.
I have installed hd tweak and I tested the sound with Coreplayer and the inbuilt one in TouchFlo.

Well Shure E2C are isolating earphones you put into ear channel. They are very sensitive, you hear everything louder than on any other type od headphones especially noises. And there is hiss/noise trust me. I also have headband Sennheiser HD580 & PX100 they are ok with HD. The trouble is that there is no hiss/noise at all if I plug shure's into my computer (SB X-Fi Extreme Music) and quality is also bit better.
I also have isolating earbud type headphones and the HD sounds no worse than any other Mp3 player ive used, including an iPhone or N95 8GB. Its not a high end audio device, comparing it to a 24bit reasonably high end PC sound card is not fair.
OK pass, I'm an audio-freak type. Maybe I just expect to much from HD
using UE triple.fi 10 vi's and the sound from my MP3's on the HD is very good... i have no complaints.

Vibrant Sound Out + Car Aux In

Hi guys, my 328i has a built in Aux input. And it works great with my Vibrants 3.5 output jack. The only issue I have is, the volume is just not as loud as It is listening from the mp3 CD. The volume for both the phone and car is at full volume.
When I usually listen to mp3 cds, the sound goes up way louder. Is there a way to hack the phone to output louder through the 3.5 jack? Or if any of you have the 328, is there some option to do that?
I don't know about mp3 cds but as for official cds bought from the store, they are definitely a lot louder that the phone through aux jack. Same deal with my g1 before I got the vibrant.I'm sure once the rooting and custom recovery is all sorted out and we start getting some custom roms, the devs will include volume hacks just like they did for the g1.

I'm quite satisfied with the volume. If you need to blow your ears off boost up the EQ.
Actually, it's really weird. Through headphones I can equalize my Vibrant and iPod to sound the same, but through AUX, the vibrant is quieter (Same volume settings). Really makes no sense to me. It has to be something with the equalizer...
Edit: But it is in no way quiet. I have to turn up my car stereo by like 4.
Try a different cable or a higher quality audio file.
I play songs between 192kbps to 328kbps and have no problems. The volume is at the same level since I used my mp3 cd.
appreciate the inputs, i'll look for the equalizer on the phone.
Have you guys tried sending the audio thru bluetooth audio enable car radio? Pretty cool no cables needed
I can even listen to pandora and send the audio to my stereo

whoa, i'm going to have to try this out. any advice?
I have the Pioneer Z110BT Navigation and it has bluetooth audio. Just pair your Vibrant to the Pioneer then play any song on your vibrant using the music player. Click options then "Via bluetooth".
Then go to your stereo and click on bluetooth audio. Voila! Streaming music from your Vibrant to car stereo. The sound is also great!!
Not to hijack this thread but my one complaint of the phone is how low call volume and audio volume are.
Everythings turned up to max and this phone is roughly half as loud as my MT3G is set at 50%.
I have a Sony xplode and play through Bluetooth, I get great sound.
I have no issues with call sound or ring levels. I actually have to turn it down sometimes because its to loud.
Sent from my SGH-T959 using XDA App
I built a custom cable to connect the headphone jack to my Pioneer's IPBUS connector - it works great, and is very loud. I keep both the head unit and phone's volume on half way, and depending on the song I may have to turn it down, too.

[Q] Sound Issue... HELP!

Has anyone had issues with there audio through the headphone jack? It sounds like I am listening though a tunnel!!! And even through the speakers I notice it a little. Any suggestions?
I had this issue with the first set of headphones I tried (the set that came with my Samsung Galaxy S). I swapped the headphones for a better set (Sony's standard €20 earbuds) and the problem was fixed.
Just disable Dolby Mobile in Settings when listening with the headphones. Dolby Mobile seems to be related to (optimized for) the internal speakers.

This will indeed fix your issue. Also make sure the jack seated correctly... sounds silly but on the iconia I have noticed many times that it didn't correctly sense my headphone jack and audio was coming through the cable but sounding very thin, as well as still playing out the iconia speakers.

getting very bad bluetooth audio quality

iam having the worst ever audio quality over bluetooth while listening to songs...whenever there's treble it sounds like a worst radio quality..iam using sony ericsson MW600 bluetooth stereo headset..does someone have a solution for this? or is this universal problem?

That sounds like it's using the hands free profile instead of A2DP. You could try going to the options of your bluetooth headset on and untick the "Phone" box, and make sure "Media" is ticked.
I have generally decent bluetooth audio using Motorola T505 to broadcast FM to the car radio (must get around to buying a proper BT head unit, or a new car with one built in...). Most of the problems I have are interference with the FM signal rather than dodgy bluetooth.
However, I do see this kind of bad distortion on the high end with certain pieces of music - generally the solution is to turn down the volume on the Note a couple of notches and crank it up on the car stereo. I assume some of my tunes are just recorded/ripped REALLY DAMNED LOUD, it seems to mainly be things I ripped myself years ago so I probably didn't pay much attention to the levels at the time.
If you lower the volume from the Note does the distortion disappear?

No, still there. I'm using Galaxy note and noticed a similar problem, both with a pair of Plantronics BackBeat and bluetooth car kit FM transmitter. It sounds pretty fine on my Archos 5IT that is running Android 1.6 and my Nokia N900 running Maemo. My note is currently running on Android 2.3.6 Rocket 12.
Bluetooth stereo sounds great for me using Sennheiser MM-200...
If you have exceptionally bad audio quality, it's probable that the headset is being used in handsfree audio mode, and not media mode. If you go to settings>bluetooth, and click on your device, you should see which modes are ticked.
Also, some people have reported better bluetooth audio quality with the LR1 modem. See here:

Question GSMARENA Nothing Phone Review Audio Issues

So GSMArena spent a bit of time on their detailed review saying that there is something VERY wrong w the audio quality of the Phone 1, in regards to using wired or wireless headphones. They stated that the Phone 1 had a "disastrous frequency response" and also that "it's not the only issue either - stereo crosstalk is so high (-3.9dB compared to -85dB or lower for just about every phone) that the phone's stereo effect is severely compromised." They did just update their review after the most recent firmware update and stated the audio was still NOT fixed. Can someone comment as to if they've had audio issues with the Phone 1, or that they noticed audio quality sucks? I'm thinking about purchasing but I use my phone for 2 hours a day in the gym streaming Bluetooth audio and obviously this would be a deal breaker if the Phone 1 has ****ty audio quality compared to every other phone. Thanks in advance.
One of the speakers is just the call speaker, so the stereo speakers are kind of bad, but otherwise they sound fine. With BT headphones I didn't have any issues (other than not being able to choose codec, but that has been fixed in the latest update).

Sorry I didn't clarify. They weren't talking about the external speakers. They were talking about audio quality measured via wired and wireless headphones/earbuds.

I cannot report on wired as I don't have a usb-c to 3.5 jack converter, but no issues with wireless.
I have tested mine with a bluetooth headphone and with an usb wire with the same headphone, I didn't heard to must difference with my iPhone 12 mini ( I just play a movie with song and speech )
I'm not an pro audiophile so maybe I'm wrong

I've tried both and had no problems with either wired or wireless headphones. The only thing I noticed was that I used an adapter that allows you to charge your cell phone and connect headphones. As soon as I let the device charge, no sound came through the headphones. I didn't have this problem with my pixel 5.
