Has anyone used BOSE SoundTrue (one without the phone call/microphone option) with V20? I had interesting experience. When I played YouTube video (strong bass, loud beats, etc, etc) the first time around, there was hardly any difference in the quality w/wo DAC (in this instance, I kept turning on and off the DAC option during the video playback). I replayed the same video again, and this time, there was a clear difference of quality where the sound was lot more crisp and solid (when the DAC was on).
Has anyone had experiences
a) something similar but with different company head phones? (i.e. sound quality once good and not so good at other times with the same song/video)
b) something similar with SoundTrue? If so, do I need to get better earbuds? BOSE SoundTrue has been great overall so far for me in general
Sometimes I have a problem with the headphone plug on my high impedance headset. I've had to spin it around or replug it to get it to switch from being an external or normal device to high impedance one

I was playing with my friends Atom the other night (and I have one on order myself) and I wanted to see how the bluetooth worked. So, I used a bluetooth adapter on a computer to become a stereo receiver for the Atom. While I had no problems getting the device working, the quality seemed outragiously bad. I was playing an MP3 in Windows Media Player, and the sound played over bluetooth sounded as if it had a high pitched squeel over it the whole time. With this kind of quality, I question being able to use a set of bluetooth headphones with the Atom. The quality was not a problem in the MP3, and it sounded find out of the Atoms speakers. Was I having some other problem, or is bluetooth stereo sound just this bad?
On mine it sounds better on BT stereo than thru' speakers :lol: Maybe your pc corrupted the soundz
Well, I suppose "better" could be rather subjective. But when using the PC as a stereo speaker it sounded bad. I imagine with that kind of sound on headphones, my head would explode out of sheer pain. I'm certainly willing to accept that my PC bluetooth software could be causing problems, but I'd like to hear what others think before purchasing a set of bluetooth headphones. I would be describe what I heard as if it had been overcompressed sound with horrible high pitched artifacts. Would you say that the actual sound being sent to your headphones was phonically the same, ignoring the quality of speaker vs headphones?
Remember "Garbage in Garbage out" :twisted:
The same MP3 played on the computer it's being transfered to via bluetooth (and therefore the same speakers) sounds perfect. What I'm wondering is if bluetooth stereo quality is as bad as I've just experianced, or if it was something outside the normal "headphone" system that was causing this (such as poor receiving software).
Fortunately tonight while browsing the forums I came across the following,
http://forum.xda-developers.com/viewtopic.php?t=54621
This completely cleared up my sound quality issues. Sounds like what I'd expect now. Hope this helps someone else.
Tell me. Which settings did you apply? All or some of them. There are so many inputs you cannot even know ehich is which :roll:
I changed only Bitrate:
Bitrate 53 increased the frequency of breaks to almost one every 5 seconds. My original was the default 30 which was just fine at less than once every 2-3 minutes.
Am currently testing 35. Hissing is gone, but the ocassional cut is still there @ once every 2 minutes.
Hey,
I was wondering how good the audio-quality is with some decent headphones? I have the Hermes with an adapter for ear-plugs, the sound is quite good for a phone, but not compared to a proper mp3 player..mind you, I'm a hifi-music guy and have quite good hearing (comparing headphones etc. no problem)
the audio is just fine and loud enough but not extremely loud! Dont worry. If it is a European device you can use diamond tools and disable the european union 100db sound limit.
that's good to know about the limiting..
and how is the quality, not just the loudness, like the base comes through clean, the sound is weighted equally and such? and when you turn the volume up, the signal stays clean (no clipping etc..my hermes does this)
The sound seems decent enough to me as well.
i'd imagine there would be clipping in a device like this, however I can't confirm at this point in time.
As anticipated, there are noticeable hisses.
Reference:
- 320kbps songs
- Sennheiser IE8 in-ears
- TF3D's audio booster on (R & B--on/off indifferent, really: hisses still there)
- system volume on last bar (i.e., lowest)
Overall, I find the HD alright. The siblence sounds become less obvious with the stock buds, but with in-ears they are expected (both with TF3D and Coreplayer). Needlessly to say, no phones are mp3 players--a little compromise is liveable.
-cheers
Crappy quality through windows media player and good ipod quality if played through the music touchflo3d tab.
mmm... that is odd... why the difference I wonder?

probably the equalizer settings are better in the music tab.
Indeed i find WMP appalling on desktops as well, however you try to change the EQ.
The HD seems ok to me, i use Sennheiser CX-300 ear buds, the stock heaphones are a horrible shape and hurt my ears.
Does the HD have any way to output audio through the mini USB on the bottom? If so, one could hook up a cleaner audio signal, and if it's line out level, one can hook up an external amp.
When listening to tracks with any silence through my high quality headphones, I have noticed a large amount of noise generated by the Imagio's audio output circuitry. Figuring this was due to all the radios packed into such a tiny package, I listened to the same track with the phone in airplane mode: Same sound.
It also makes no difference whether the phone is charging or not.
The quality of the noise does change, however, depending upon what player I use (in addition to the HTC and WinMo players, I also have TCPMP). This leads me to believe that a purchase of Coreplayer may be in my future.
Anyone else noticed this? Can anyone compare the stock players to Coreplayer? I realize any audiophile would scoff at me for expecting clean sound from a cellphone, but my Q had excellent performance in this area!
Check the system volume level. I had the same issue until I lowered the level to 60%
I don't notice any noise with mine
It is noticed that while listening through headphones that the sound is being affected by some sort of 3D/spacial/EQ process that might give the impression of "punch" for movies but at the expense of phase-y sounding vocals and smeared high notes for music.
Yikes. Thst stuff is not good for music quality. No way to turn off? The settings options seems kind of scarce.
After playing around with various music players and headphones it seems that the audio is now OK.
Not sure what happened. It may have been a headphone jack issue. Audio sounds great now.
Oooops!
There is an issue with sound quality. Compared it to a Rockbox'ed Sandisk Clip Zip with a very wide stereo track 2-channel stereo track (fyi -- Brook Benton's "Kiddio" 1960). There is some EQ bast boost and high frequency crossfeed that narrows the stereo separation. I'm going to boot from CM and see if the problem persists.
For video I would not notice the issue, but could get to me listening to music with my Klipsch S4 buds.
Update:
It is not bad. Seems part of the issue is low gain which can be increased with Volume+ or other similar app function.
Volume+ did the trick for me. Jamming to some Coheed at the moment. Sounds as good as my other tablets now
The problem was never with volume -- I think stock has plenty of volume for driving Audio Technica ATH-900x. The problem is with some sort of audio processing that affects the soundstage and frequency response.
I am not hearing it using the Google player app. Gain is not the same as volume. Both need to correlate or weak quality.
SRS processing is used and applied at the headphone output. See HD+ file \system\etc\srs_processing.cfg
This is what I use, have my settings set to Jazz "my preference", audio sounds great, not talking about low resolution MP3's.

I understand the config issue, but I am not hearing it. I should hear the sound manipulation with cymbal decay as example, but not hearing it. Weird.
Playback in CM 10.1 has the correct stereo image.
so am I
so am I ,after checking
First I need to add that I find the so much advertised two DACs of the Axon very highly exaggerated in terms of power. They are just too weak, even compared to my previous Note 3, both on headphones and speakers.
Second, they seem to not be able to be effectively used on almost any app since 98% of apps do not utilise them by default and one cannot change it.
If you tweak Dolby Atmos a bit you can get it to amplify the general audio output, both on speakers and headphones, and this is why I use it predominantly. I am on the B09 update on A2017G and it is still very buggy. No matter what setting I choose, i.e. Music, Voice, Game, Custom, when I leave the Dolby Atmos screen it drops sound for a second and always resets to Movie, no matter what. Also the sound regularly interrupts, especially when unlocking screen or doing things in the background, or just on its own.
What annoys me most however from when I bought the phone is that at very low or low volume (only on speakers), when there is speach or the music starts, there is some kind of hissing, ss/sh-ing sound corresponding to the words said or the tiny beats of the music played. It's like a background noise added on purpose simultaneously with special, mostly high frequencies, i.e. words, tiny/starting percussions or similar, no matter the Dolby Atmos setting. This noise stays apparently at all times, it just is not heard when more, mostly low and middle frequencies get in. This "noise" is not available when no Dolby Atmos is used, however the volume then drops by a few levels down. Good or bad, Atmos also adds some spatial effect to the sound, which is why I like it for...
Does anyone of you, an A2017G or A2017U user, observe similar behaviour on your device? Is Dolby Atmos working better for you, i.e. unconditionally steady settings, no low volume added speakers noise, no sound interruptions?
I also noticed browsers do not get use of the DACs/Dolby Atmos, i.e. YouTube, online videos, many video players. My favourite before Aimp was unable to do so also so I had to transfer to Jet Audio and PlayerPro, both of which can work with the Dolby.
Why did ZTE add (two) DACs when they couldn't be used by 95% of the apps and games by default and even manually, also there seems to be no gain in output at all? Was this the case with the Lenovo Phab2 Pro's Dolby Atmos? For the "regulated hiss" (not present on headphones at all) I cannot currently watch any movies on the phone with Dolby Atmos enabled, unless at very high speakers volume. It hisses so badly every time a word is pronounced or some subtle 'invisible' sound plays. The same is with playing music...
I dont use Dolby when I listen to music - it makes everything so much worse and much quieter. Listening to flacs on stock music player with Super HiFi on. No hisses on low or high sound levels. Silence is silent. as for speakers - no hiss also.
ZTE did not add 2 DACs for music, 1 is for music other one is for audio recording which is records at 128kbps. and quality.. I dunno it's quite clear, I had recorded a room full of people, with two girls singing and some people chatting in backgroud and I can hear everything. but sound itself if on the lower end, girls vocals are lower than they are, everything seems shifted to lower sound spectrum.
Tooks some time and checked spectrum of that sound file 50-2000Hz. everything over 2kHz is just a noise.
and a little edit: it records nothing less than 50Hz - total silence there.
The stock player is OK but it's lacking on features, also not sure if it can play video.
I have noticed the low volume speakers "noise" with Dolby on when watching movies using almost any player - VLC, BS, MX and more. If I go above 30-40% volume it seems to disappear, but more like you don't hear it and it stays. I say "noise" but it is like a hissing/ss-ing sound added to sole frequences only, i.e. speech only or single instruments. When more frequencies get in, you don't hear it. Weird these don't exist at all with the Snapdragon amplifier, i.e. when Dolby is off.
https://community.zteusa.com/thread/12853, here is a similar thread in the ZTE USA community. I believe it has something to do with the Axon's own amp or its software and happens at low volume only. There was a thread in Reddit exactly about what I am reporting but I can't find it now.
If you go to your phone's Music\Settings\Dolby Atmos app, then move all sliders up you will notice that it significantly increases the overall volume when Dolby is on. So it's not low, if you change it, it boosts up the volume by at least 30%. On another note, the Axon's mic recording quality is quite poor/muffled, even compared to the old Note 3, hopefully they will improve it at least a bit by some future update.
I bought the A7 exclusively for its audio capabilities so am disappointed that I have to report insufficiencies in this exact area.
Does your Dolby Atmos set itself to Movie only if you exit the Music app? Are there any drops in sound when it's on and you do something in the background?
There are two DACs. "AKM AK4961 DSP CODEC, which can be considered the primary chipset for Hi-Fi audio playback and recording. The AKM AK4490EN DAC is an independent Hi-Fi audio sampler". So AK4961 works in standard mode and AK4490EN in Super mode. ADC is only in AK4961.
You can consider rooting your device and install ViperFX or the whole A.R.I.S.E. sound system. That will solve all the problems with sound output. However the sound recording filtering is surprising, leaving only the vocal spectrum is not normal. There should be a setting somewhere.
I have the Chinese A2017 model running Oreo & have just noticed this hissing sound which can be heard at lower volumes when I keep speakers close to my ear. I don't hear any hissing sound using headphones. I wonder if it's always been there or it's a hardware/software issue. I'm probably gonna hard reset the phone to see if it goes away. Anyone could fix it?
