[ZTE Axon 7 Questions & Answers] r3xx3r:
Okay, I think it was actually my fault that there was an audio problem. I have been using an app called Automatic Call Recording for a few months on a couple of other android phones. I had installed it on my Axon 7 while I was setting it up. I uninstalled it and now my audio seems to be better. Everything is quite loud and actually sounds great. I can't use the earbuds at max volume without hurting my ears. Just don't use that app and you should be fine lol.

"I received my Axon 7 today and I can honestly say I am very disappointed in the audio quality. I was expecting the dual speakers and included earbuds to output at least good audio, and somehow I can barely hear anything from either the dual speakers or the earbuds even at full volume. I am extremely disappointed. When I watch a Youtube video using the dual speakers I turn the volume up to max and still the audio is very quiet. I made a few phone calls and could barely hear the other person on the dual speakers, earbuds, or normal earpiece. Idk if there is something wrong with my Axon 7 specifically, or if maybe there will be a software update soon to fix this, but this is completely unacceptable."
[ZTE Axon 7 Questions & Answers] dennis96411:
That's really odd. The PC Mag review said it was louder than both the HTC 10 and Alcatel Idol 4S. Have you tried messing with the audio effects?

EDIT: Never mind.

When I get my Axon 7 in the next 24 to 48 hours. I will post my initial impression of the Audio Quality/Power Output. My ASUS ZenFone 2 was average to slightly below in terms of power output. So I will know how good or bad the Axon 7 is in power output.
[ZTE Axon 7 Questions & Answers] dennis96411:
I was able to make my OnePlus One's dual mono speakers sound relatively decent with a lot more bass than they originally output (it was basically nonexistent until the volume is maxed out) using ViPER4Android. They sound almost like the iPhone speaker, which is decent enough in terms of bass and quality for a single bottom-firing speaker. I can only imagine what it can do with these dual front-facing stereo speakers.
[ZTE Axon 7 Questions & Answers] osmosizzz:
Have the axon 7 and am had a little listening session last night.

Headphone ? : V-Moda M100.

Past phones with good DAC? HTC 10, Note 5 and S6 (Same DAC as note 5).

Compared to the others, the DAC delivers. It's a relatively flat sounding DAC so you get no shape in sound. Everything is clear and concise. The output is great. Drives the M100 fine but then again, it's a 32 ohm headphone. Using power amp (yes I like that better than neutron), I set it up to play music in 24 bit mode. Immediately with the AKM 4491 (axon DAC), you hear how crappy mp3s are. Even at 320kbps. High bit rate acc sound enter but with this phone, lossless shines. The difference is not like you'll dump your mp3 library but you'll enjoy lossless a lot more. Great stereo separation, fantastic noise floor, no white noise. Just clear clean audio. BTW this phone has two audio chips as mentioned however. One is for recording and the other for listening. The amplifier is the AKM 380. Overall very pleased with the sound. Better than the note 5 Wolfson DAC and hard to compare with the HTC 10 since I only owned it for a week.

USB Audio working on axon 7?

Please If any have some usb soundcard or DAC player to test it with OTG cable on Axon 7.

Thx

I think we all know this comment is B.S. !..

Have the one plus 3 headphone jack output is amazing. Looking at the axon 7 though :)
[ZTE Axon 7 Questions & Answers] mikemaddux:
If anyone gets a chance to compare the Axon 7 speaker output with that of the Nextbit Robin, I'd love to hear about it. I currently own the Robin and I think the speakers sound pretty good, but I would switch if the Axon 7 were significantly better.
[ZTE Axon 7 Questions & Answers] RojasTKD:
Had the Axon 7 for almost todays now. Gave a quick listen to the audio last night with my 80 ohms Beyerdynamic DT 1350 headphones (portable on-ear) and I can tell difference between the Axon 7 and both my Nexus 6P and LG G5. It get a little louder and sound noticeably better. There is more punch to the bass and seemingly more dynamic range.

The LG G5 and Nexus 6P aren't really strong in the headphone jack area, so that's no great surprise. I no longer have my Note 4 that had decent audio output, but I think the difference is more noticeable with the Axon 7 than the Note 4.

I'm slightly disappointed in the dual speakers though. They sound good and do sound a bit better than both the LG G5 and Nexus 6P, both of witch have good speakers in their own right. It just dosen't seem louder than those devices, and if so not by much. It's not that the Axon 7 doesn't have very good speakers, but from some of the reviews I was expecting it to be louder.

Despite the LG G5 having only one bottom mounted speaker I think in a noisy environment it will continue to be my choice for listening to YouTube videos, as I find that it's tuned more toward the low end and makes hearing Dialogue in noisy environments easier .
[ZTE Axon 7 Questions & Answers] ipmanwck:
Great man. Had op3 and headphone jack was amazing just too many compromises coming from my g4 so now back in that. Can't wait to try A7
[ZTE Axon 7 Questions & Answers] RojasTKD:
UPDATE:

I apparently had Dobly Atmos on while listening to the headphone jack. Turn that off and the headphone jack sounds even better, more bass punch, cleaner sound and can drive a little louder. It can even make my HiFiman HE 500 sound pretty good.

EDIT 2: What I said above apparently applies mainly to Google Play Music. Apparently Atmos can be good with spotify and I think my music from the Google Pay Music library sounds better without Atmos.
[ZTE Axon 7 Questions & Answers] CandyFoxJ:
Headphones: Sony MDR-V600

Compared to my 6P the audio is noticeably better.

If you're a bass head that thinks everything should rumble when you listen to music, it won't please you but music isn't supposed to be drowned out in one frequency or the other. This is a pleasant listening experience.

My Audio Technica M50x sounds more alive with Dolby Atmos On.
[ZTE Axon 7 Questions & Answers] neovalkyr:
To those who have tested Dolby atmos did you go into the Dolby app and adjust the settings? Because adjusting the setting will give a much better sound. I too thought it sounded better with Dolby turned off in certain apps but after adjusting the settings in Dolby it's clear Dolby on sounds better. Increasing the eq bands etc. for example.
[ZTE Axon 7 Questions & Answers] RojasTKD:
Gave it a go. Nope, for my audio files through Google Play Music app or the Axon 7's build in music player Dolby off sound way better, louder and less dull.

For Spotify and Pandora Dolby on sounds best, less dull.

I prefer not to have any artificial audio processing if possible, but the above works for me.

UPDATE:

Using IEM is a different story. Google Play Music sounds bad with dobly Atmos using my big (overhead) headphones but good with IEMs/in-ears.

Spotify and Pandora sounded better with Dolby Atmos enabled with my headphones but with IEMs the difference isn't as dramatic, though Dolby does sound better, if a little processed.

Looks like it gonna be trial and error to figure out what works best when and with what.

I hoped the DAC is strong enough for my headphones, sadly it is not. Still way better than on my Old OPO

The audio warning on the USA model is there like it is in the European version.
[ZTE Axon 7 Questions & Answers] Controllerboy:
I'm very pleased with the audio output of both speakers and audio jack. My previous phones were the Nokia 5530 Xpressmusic, the LG Cookie,the Motorola Defy+, the Oneplus One, the Nexus 5x and none of these phones came close to the Axon 7.

Being a bit of an audiophile, I've also used the Sandisk Sansa e200, the Sandisk Sansa Clip, the Cowon X5, Cowon D2, Cowon Z2 and the Fiio x3. This phone sounds about as good as the Cowon and Fiio players, I'm very happy I don't need to carry an extra FLAC player around anymore (250gigs in my A2017G).

Head- and Earphones used: Sennheiser cx 2.00, Sennheiser HD-25-2's, Grado PS500's.
[ZTE Axon 7 Questions & Answers] EsaNahka:
It's "long time" from that last post, I know.

But still... thread isn't dead yet ☺️

So, any help from here maybe.

I was planning to buy Axon 7(Europe version) but there's one thing I just can't find good answer.

For me bt audio, good battery and good front facing speakers are important things.

So anybody here listening music via bluetooth headphones with Axon 7?

Every test etc skips that part even there is many good bt headphones available these days and many of us use them.

So even there is good dac for 3.5 jack how is that bt audio quality on Axon 7???

And is that connection mostly stabble or any bugs?

My current setup is HTC One(viper4android) with build in aptX for bluetooth + fairly good bt headphones(http://www.whathifi.com/philips/fidelio-m2bt/review) but it seems good old One wants to retire at last and I just don't wanna be too disappointed with next phone.

I have compared that Htc bt sound to Huawei Honor 7, Galaxy tab 3 and Iphone 6s and with that setup it beats them all.

So how is it, I'm the only one with bt headset or anyone else?
[ZTE Axon 7 Questions & Answers] RojasTKD:
My Axon 7 fell into the bathtub and now my screen doesn't work. So I haven't used in a few months. But I used BT with it in the gym 4 to 5 times a week. I was perfectly happy with it. I don't know that it's any better or worse than any other phone with BT and AptX. I may have gotten a little more volume out of them than my other phones, but not 100% sure if that true.

I don't think they will sound worse than what you already have.
[ZTE Axon 7 Questions & Answers] rolfey83:
I'm in the UK, and have a G version of this phone, before updating to Nougat the audio level was a joke, the Equalizer isn't that good even now but I will say on Nougat the headphone audio is really good now.

The front facing speakers were always insane.

[ZTE Axon 7 Questions & Answers] mitchelln:
http://europa.eu/rapid/press-release_IP-09-1364_en.htm

So most manufacturers comply when the device is launched to avoid complications and then ramp up the volume in a subsequent update. I've found this to be the case on the last 3 devices I've owned.

It is very unlikely that this legislation will be overturned and I doubt Brexit will change matter for British citizens.
[ZTE Axon 7 Questions & Answers] EsaNahka:
Ok, little update. .

Local web shop told that they have "30-day free to try/money back" -option so I decided to order it and just test it for myself.

Thanks for your answers. Maybe we'll see again some day in here xda ?
[ZTE Axon 7 Questions & Answers] rolfey83:
I believed that it was a misinterpretation of EU laws rather than an actual law that was the cause of such a low volume setting?

[ZTE Axon 7 Questions & Answers] tele_jas:
Ever since I got my first Android phone with front facing stereo speakers 3 or 4 years ago, HTC M7, I knew I'd never be happy with any other style of phone. I've tried the Samsung phones, OnePlus, LG, and other phones with bottom or back firing speakers and I just can't stand to use them since the M7 days.

Since the M7, I've had the following phones with front firing speakers:

M7 (of course)

M8

M9

Moto X Pure

Nexus 6P

Axon 7

The Axon 7 has the absolute BEST sound and volume of any of these. The M7 is close in sound, but not volume....The Moto X Pure is close in volume, but not sound quality. The Nexus 6P has one inherently louder & fuller sounding speaker (the top one), so it never sounded as good as any of the others, but still better than any bottom or back firing speaker.
[ZTE Axon 7 Questions & Answers] aLexzkter:
I don't understand your message.

"The Nexus 6P has one inherently louder & fuller sounding speaker (the top one), so it never sounded as good as any of the others"

If it has the loudest and fullest sounding speaker, "the top one", how can it never sound as good as the rest? It's contradictory :confused:
[ZTE Axon 7 Questions & Answers] tele_jas:
That is a little hard to follow...

(Speaking of the Nexus 6P) In comparison to its own bottom speaker, its own top speaker sounds better than its own bottom speaker... So, The top speaker on the Nexus 6P sounds fuller than the bottom speaker on the Nexus 6P.....But not better or louder than another phone.

Axon 7 eu version b09 have problem with dac driver, update to nougat will be better
[ZTE Axon 7 Questions & Answers] amarryat:
I had those three as well, but went with the LG V10 after the M9. And I agree with you. This is even better.
[ZTE Axon 7 Questions & Answers] nolimit78:
On stock, the front facing speakers are /insanely/ good. Seriously. You don't understand how good they are until you hear them for your self. If you're close to a best buy, I suggest checking out their demo unit. That's what I did and I only looked at it for 30 seconds. I quickly sold my Galaxy S6 and bought the Axon7 on swappa.

As for the quality of sound pumping through the headphone jack, I'd suggest modding your phone and using ARISE4Android. There's a how-to-guide in the help section that makes it all sound much better. The stock settings are.. meh. Run of the mill really. After ARISE install? Best on market.
[ZTE Axon 7 Questions & Answers] EsaNahka:
Ok, long answer to my own question, sorry :)

I mentioned after that post that I found a deal from local shop that I can test Axon 7 for 30-days and return it if it's not good.

Now I have tested it over a week and got to say phone is amazing. Every game/app works without any lag etc... except google chrome, there is weird lag-bug with this phone but it's not big deal.

About that music quality.

Compared to Htc One, best of those I mentioned, Axon's speakers sounds better and louder. Those are just GREAT!

Not really sure do I or do I not like that Dolby Atmos just yet but it surely should at least have more frequencies to tune manually in custom profiles.

And about that bluetooth audio.

Along with those others I got possibility to compare Axon 7 with LG G4(also with aptX). Tested mostly with rock and heavy music.

Axon's bt audio sound is quite good but I think it's not as clear/crisp as in HTC One and LG G4 with aptX. But I wouldn't say it's bad neither. Could be problem with over 400€ top quality bt headphones but with these "good cheaper" I think I can live with it. Also viper4android is big advantage in One.

Can anyone say anything about viper4android or similar with Axon 7?

Battery life. With much browsing, listening music and bit games I have never got SOT better that in those pics.

Bt and fingerlock always on, many others(nfc, wifi off while screen off, mipop etc) off.

Not saying it's bad but while GsmArena etc got over 11h web browsing time I maybe expected too much of that battery. Of course it depends on many things but still. In light usage if phone is most of the day just in my pocket while working it's about 2.5%/h battery usage.

But I think I'll keep this phone while I can't find anything really annoying or bad on it or any other phone that actually is better on that price. It also looks and sounds good and I even got my fav Htc Sense launcher on it :)

Btw, does anybody knows anything about official nougat update on Europe? I just read its freezed because of nougat bugs.
[ZTE Axon 7 Questions & Answers] ++chris++:
Nougat 7.0 is very good. Minor bugs as any smartphone.

If you love good sound, use 3.5mm jack.

The AKM DAC is excellent.

Should buy some high class earphones/headphones with high impedance.

The included ZTE-earphones can be a surprise...

...if you implement them into individually formed ear plugs.

The main handicap of the ZTEs is the apple-design.

It does not fit properly and looses bass and middles.

Basically only tin sound remains.

If plugged in perfectly, they amazingly improve
[ZTE Axon 7 Questions & Answers] vision33r:
I've had the Axon 7, I have to say the only phone that sounds better is the HTC 10, that's my own preference. I don't think it's much better but with any headphones it is consistently good. Motor X Pure sounds like any other Android, the DAC is weak and speaker not good.

I've sold the Axon 7 because just got tired of the signal problems and picture taking is weak. HTC 10's only weakness is the screen is a bit small for my preference but it is imo what ZTE and OnePlus but tried to copy but fails at. HTC beats them both in the software dept and photo capability. The sound quality is really good.

As far as I know, the best speakers on the current phones are coming with the Alcatel idol 4s.

Considering the opinions by people who owned these devices.
[ZTE Axon 7 Questions & Answers] Galaxo60:
That's because JBL included its own DAC and speakers into the device, and as far as I know, they are the louder speakers in the market right now.

I have the Vodafone Idol 4S variant as well and I can say that the speakers are really good, but clarity and deepness are better on the Axon 7.

Actually, I only got my Axon 7 because it seems that Alcatel abandoned the device (or maybe Vodafone) and it won't get any further updates, but I can say that I feel I have the same device, specs are almost the same and there were not any noticeable upgrade from the Idol 4S to the Axon 7 except for the camera, which Axon 7 has considerably better one.

;)
[ZTE Axon 7 Questions & Answers] tele_jas:
I guess I was more referring to the actual speakers on the phone itself. I really can't tell much difference in earbud quality with my $50 earbuds.... Plus, my music player is pretty "advanced" and combined with (or without) Dolby Atmos, can make even the cheap $10 earbuds sound pretty good. But HTC has always been amazingly great sounding through earbuds/headphones.

Is there any point in connecting a usb DAC to axon 7? Will it make any difference? I just bought the axon 7 and wondering if its worth spending another 90 euros to a fiio usb DAC+amp.

Just a word of caution; I tried hooking up my FiiO E10K via a USB-C to USB-A female adapter, then with an A to micro-B cable, and it didn't work.
[ZTE Axon 7 Questions & Answers] bhazard451:
To use a USB DAC with the Axon, you must use a cable that is terminated USB-C to Micro-USB. Adapters won't work.

Unless the DAC is something like the $500 Mojo, the AKM chip is more than capable in the Axon.
[ZTE Axon 7 Questions & Answers] Kingo64:

Hey everyone, hope all is well.

I found a fix for my axon mic issue. If you don't want to read my trial and errors and just want the fix, scroll to the bottom. Maybe fixes your mic issue you mentioned

I bought an axon 7 off eBay. From day 1 people were saying they couldn't hear me very well. I thought it was cell service.

It seemed to slowly got worse.

It got to the point where people couldn't hear me at all.

I downloaded an app to locate cell towers and service range. Service didn't seem too bad...

Found forums like this one, tried talking on speakerphone. It worked, but people said it was still hard to hear me, cutting in and out, etc. Turned off mic access for ok Google and eventually EVERYTHING else.

Deleted apps even... No fix.

Eventually went to a place I knew had good cell service, called someone, and they couldn't hear me at all! Def not mic access, def not service...

Axons warranty doesn't work for resold phones... The speakers and Dolby..I didn't want to go back to a Samsung or whatever..

That's when I started looking for hardware fixes.

I decided to do a Google search one last time before starting down that road, but looked at videos this time.

And I found a fix

youtu.be/KNGMM-H0oxc

So simple. Take a needle to the tiny mic holes. Mine was so clogged, the junk in it actually looked like the hole until the needle disappeared into it like a toothpick into a brownie hah.

Crystal clear on calls now.

So going back to the forums I read before and posting my fix. Hopefully it helps others.

So happy!

[ZTE Axon 7 Questions & Answers] Androowner:
Hello,

Overall I really enjoy the sound of this phone.

But I have a little gap with this, I would really appreciate that it would confirmed or lights up about this:

when playing music on aux or headphones, there are little click can be heared on the left speaker between tracks with stock player. Same when turning DAC on or off.

For me it's seems to be faulty something.

The second is on phone call the other side could be louder. It's ok for home, but not enough at outdoor. Turning on the external speakers in this case help. (the built in stereo speakers are REALLY good, so thats why I don't unterstand.

Any help would be great because I use the device is less than a month and I would not happy to send it back.

Thanks.

When I was tryin to fix mic issue on my axon 7, I google searched and clicked multiple threads looking for a fix. Different ppl on each one.
