White Noise and Clicks on Headphones - Google Pixel 2 Questions & Answers

Hey Guys,
I already read about the click sounds on earpiece but I have another problem.
I connect my QC25 headphones via the USBC to Audio jack Dongle but as soon as music is playing for 10-15 seconds I get quite loud white noise. When I pause the music it will stop eventually after 10 seconds.
If I increase volume the white noise also stops. Sometimes comes back with some clicking noise.
Anyone else has this? Pixel 2 seems to have many problems. Very poor quality for this high price.

Might the problem come from the adapter you're using? The audio coming from the pixel itself is digital and that should be free of white noise. I'm pretty amazed by the quality of sound coming from this little adapter and have not had the symptoms you described. Sorry to hear this.

I have exactly the same headphones and issues you have. Did you find any solution for it? RMA the USB-C dongle?

[HARDWARE PROBLEM] Headphone jack static/hiss noise?

Hey guys,
I bought a One X recently, and I am noticing some static/hiss/noise coming from the headphones.
I tried connecting my One X to bigger speakers, and the noise is more noticeable this way. This is an odd issue, because none of my other phones behave this way.
The funny thing is, if you play music or notification noises play when the phone is connected to speakers, the noise goes away. But after one second, when the DAC shuts off, the noise comes back again.
My friend's One X has this problem as well, so I don't think I just have a lemon here.
Other forums seem to be talking about this issue as well

I found one review that mentions this issue. They talk about it in the Beats Audio section, and there's a video with the noise.

I remember using a really cheap chinese knockoff mp3 player about 8 years ago, and the One X seems to have the same problem as that mp3 player. Could it be that the One X has a cheap DAC in it that causes this noise?
Anyone else experience this problem?
The first link is about the international version, the lte one x is technically the One XL, and this is the first time hearing about this. Mine doesn't have a problem and I listen to music all the time.
Just and idea possibly cheap headphones?

My music is crystal clear, probably one of the best quality sound outputs I've heard from a phone actually.
Mine has this problem, but I only notice when I hook it up to my car speakers (with an aux cable) and not with headphones (Bose). It's a lot more pronounced when the phone is plugged into usb as well. Once sound plays though, the hissing stops completely. It's only when there is no output that the hiss is present.
Edit: Could it possibly be interference from the cellular radio? Maybe once the DAC kicks in it filters out the interference?
Edit 2: Just read the 3rd link and yeah, my speculation seems to have some validity
"Adding insult to injury, HTC One X features a badly shielded headset jack that makes noise whenever it is hooked up to sensitive speakers. We compared it to high-end and low-end phones, and none of them made the annoying static noise that the One X makes. This isn't a serious problem for people who only listen to music through headphones, but you may want to stay away from the One X if you are thinking about playing music through it with big speakers."
I had the same problem. If you are rooted, disable beats audio notify with titanium backup. I did this and use power amp with custom eq settings and do not notice any hiss whatsoever.

Same problem here. WAY worse when plugged in and in my car. On regular headphones no problem. In my car it's huge. To me it reeked of a poor ground somewhere, to the point that I thought my unit was defective. If it were a shielding problem I would think it would be an issue all of the time, not just when the thing is "inactive" (ie not driving the jack). I've "disabled" beats to the extent that I can without rooting, and it had no noticeable difference.
Glad to hear it's not just me.
I notice the problem when I use both the microUSB charger and headphone jacket. Disconnect the charger cable usually solves my problem. Now, I switched to use BT car adapter instead of aux cable and I can use car charger without noise.
The problem is called BEATS AUDIO!

I still get the hiss despite disabling Beats (as in just turning it off in the notification shade), although it is definitely not as bad as having Beats turned on. I'll freeze HTCBeatsNotify and see if it helps on the way to work tomorrow morning.

Sadly beats audio is integrated beyond what you can turn off in settings.
so, the only solution is to root the phone and completely kill Beats Audio?
I guess it's not a hardware problem then... Man, that sucks. Has this issue been brought to light by some big sites yet? We need to do something so HTC learns from this mistake.
By the way, here's the update I promised...
Like I said before, I disabled beats from the notification pulldown but the hiss was still there, although slightly less annoying. I froze HTCBeatsNotify (or whatever the actual name is) using TiBu so Beats doesn't even show up when I plug it in. Unfortunately, the hiss is still there at the same level it was at when I just disabled Beats from the notification pulldown.
Is Beats actually integrated into the hardware? Is the "poorly shielded headphone jack" mentioned in one of the OP's links still a valid assumption? Can someone running CM9/AOKP chime in on whether they get the hiss?
Edit: Before I head home today I'll go into Airplane mode to try to rule out the headset jack shielding.
Annnnd of course my experiment failed...hiss is still there
If the headphone jack is indeed poorly shielded, couldn't it pick up interference from anything? Not just the internal radios?
This means we'll have to go into some radio-free environment in order to determine whether it's the headphone jack or Beats Audio that causes this annoying hiss.
In either case, I'm disappointed in HTC.

Well I mean, the internal radio would be the strongest signal in the immediate area that would cause interference. Just look at old, poorly shielded computer speakers, they had issues only when a phone would go off within maybe a yard of them. I was in a parking garage at the time I tested and I'm not sure if there was anything else around that would be powerful enough to cause the interference.
Also something I noticed which may lend credence to the DAC being the source of the issue...Just plugging my phone into usb and having the headphone jack attached does not produce as much interference as when I'm streaming from Google Music and it gets caught buffering. As in, when the DAC would still be active but no audio is output. The hiss during that situation is quite a bit worse than just having the phone sit there not doing anything.
Since Beats is just a glorified equalizer, it could be that Beats just happens to be boosting the sound frequencies of the hiss and making it sound louder, and not the actual source of the hiss itself. So maybe it is a hardware issue.
Again, I can't imagine ti being "poor shielding" because that would not immediately go away once you started playing music. Think about typical cell phone interference from a radio. You're playing music, and you hear that "bvvvvrerrerrr" sound.
In the case of the HTC, as soon as you start playing music, the hum goes away IMMEDIATELY and completely as far as I can tell. If shielding were the problem it wouldn't it still be distorted regardless of whether the jack was actively playing anything or not?
Seems more to me that the DAC is leaving some signals floating, leaving them susceptible to noise, when it's not active, when it should be pulling them to a known state (probably ground)
Not from DAC either. If you plug in a headphone, you will not hear these noises. It seems only occur when you plug into AUX import of car or amps.
So, it is a hardware design problem that causes dirty interference escaped into audio output. When you plug in a normal headphone, it has very low impendence and the noise will not get amplifed at all. If you plug it into an AUX import, it will have a much higher impendence and hence the noise get carrier over and amplified.

Headphone jack buzz

hey guys,
my One S has buzzing noise coming from the headphone jack, and this problem is pretty annoying especially when it's connected to my car stereo. I thought it might be just mine, but it seems like this is a common issue.
i found this video on youtube. I have the exact same buzz from my One S, though perhaps not as accentuated as in this video.
seems like the One X has this problem as well. found this thread at the One X board http://forum.xda-developers.com/showthread.php?t=1720212
is this a grounding problem in the headphone jack? Beats Audio? what do you guys think?
I've always had this problem with more than one phone. If you charge the phone via USB adapter from the car battery, it gets 10x worse.
This problem only happens when sound is being played back, so when music/video/game sound kick in, it stops. Do you get that noise when sound is being played back?

The buzz is only audible when nothing is playing. Like in that video, when I stop playing music it will be silent for about 2 seconds and then the buzz kicks in again.
I didn't have this issue with other phones
I don't have any buzz, I double checked just to make sure.
Although it might be my headphones, the output is probably not strong enough to play the sound.
It's probably being heard in your car (or in the youtube video) because the output is being amplified.
I'm having the same issue with YouTube and Pandora.

you're right. the issue isn't as noticeable through earbuds. i think that's why many people are saying they don't have this issue. It's still bad though.
I don't know why HTC messed up this part when no other phones seem to have this issue. Makes me sad.
If it's easy to reproduce for you guys, I'd definitely be pushing for warranty replacement.
I do not have this problem at all. On my cheap pair of headphones or on my expensive one. No hum or sound.
the buzz is there, and it also was on my Desire.
Not when playing tho, only when connected and not playing. Not too annoying, always thought it was supposed to be like that.
And no, I have never heard it through ear buds or phones, only when connected to home stereo or car stereo, and if charged through cig-lighter-outlet it amplifies further...

It doesnt effect headphones, only when the sound is amplified. Like when you play music in your car.
Simply because that sound alone is not enough to drive the headphones.

Whether its plugged in to a car or home stereo, its still using the output from the headphone jack. The power output from the jack is the same either way.
I plug mine in to the aux jack of my car stereo daily, and I have no buzz or hum. Do you have your phone plugged in to a power source at the same time? That buzz is usually caused by crosstalk from a poor quality power source.
Or, as I said earlier, it may just be a bad phone.

Well my phone doesnt do it in my headphones. I can't test in car, no aux input.
What I was saying is that, of its buzzing in your car but not on your headphones its because the sound level at which the buzz is at isn't enough to drive your ear buds. But when the car stereo amplifies it its easily driving your car speakers.

[Q] Slight static hiss/noise on 3.5mm jack

On my tablet I always get a slight static hiss/background noise during and a couple seconds after the tablet plays any sound.
This seems very odd to me since it's not affected by how loud the volume is (as long as sound is on, not at 0).
I don't have this on any other outputs (HDMI/BT/USB OTG/build-in speakers, all fine)
Every headset/speaker I use outputs this from cheapo Samsung in-ears to a quite expensive 2.1 setup.
I'm used to having a bit of noise at the highest volume levels (which for ex. my Note 3 has) and consider this normal.
But this is very annoying, especially when navigating the UI as I always have to endure this hiss for a couple of seconds.
I'm not sure if it's a hard or software issue, since normally static hiss always occured to me on lower-end devices with higher volume, and if it were a software issue should it not also do this on all outputs (including digital).
I haven't come across anyone with a similar issue.
Yep, this happens for me as well on my LTE version. It also happened on the Nexus 7 2013. The noise is from interference from the other board components in close proximity to the audio chip.

Yes, I also have the LTE version.
Bleh, that's no fun and really annoying. I have never had anything from a reputable brand do this.
The next test would be to see if it does it through USB Audio or Bluetooth Audio. I have a Microsoft LifeChat 3000 headset that I have successfully connected to the tablet, which doesn't seem to have the hiss. It could be due to the impedance of the speakers of this headphone compared with my Shure SE425 IEMs that I notice it more. I also use Tri-flange tips on my IEMs which makes everything more pronounced.

I did, My USB headset doesn't have this issue (plugged into the shield with a USB OTG cable), my 3.5 mm headphones and cheapo IEMs don't have the issue when plugged into a Sony SBH50 connected to the Shield (via Bluetooth), but they do have the issue when directly plugged into the Shield. Meh.
So that proves that it is the shielding on the 3.5mm jack.
Unfortunately, that's case closed. If it's any consolation, you get used to it after a while.
An update:
I tested with my PC's line-in input, and when I put it in any 24bit mode sound is crystal clear 24/7, I don't get any issues.
mic-in sounds garbage but that's to be expected (I can hear the tablet's internals cause distortion all the time.), it also doesn't always get detected by the tablet.
Is this of the lower impedance that the static noise gets filtered out? I'm not an audio expert.

Wired headphones : weird issue

Hi dear friends,
I'm having a weird issue with wired (jack) headphones during calls : I can hear my own microphone !
For example during a call, if I'm in windy conditions, I can hear the wind.
During such scenarios, my phone is in a pocket or in a bag, so the mic I hear is the one on the headphone's cable.
This problem arises with either the headphones provided with the Pixel, or with any other wired headphones kit (I've tested with a Samsung).
On headphones with volume control, I can even hear a loud sound when volume up or down ...
And this issue is here out of the box, without any APP installed.
My phone has already been replaced by Google support, but the issue is still there one the new one.
Does any of you Pixel 3a owners, have seen such an issue with its phone ?
This is normal operation.
If you are wondering why the noise cancellation isn't working better, you have to understand how it works. It compares the audio from the mic on the headphone wire with the audio from a mic(s) on the phone. Anything that both mics pick up is cancelled by the noise cancellation software because it is considered an "outside noise". But anything picked up on just the wired mic is considered part of the conversation and won't be cancelled out. That means if your phone is in your pocket and it isn't getting the same wind noise (for example), then the phone will not cancel out that audio because it's only being picked up by the wired mic and not both mics.
Hopefully that helps. If you want wind noise to be cancelled out, try holding your phone in your hand and see if that helps. But the wind noise may not be picked up even then depending on which way the wind is blowing vs what orientation your phone is being held in, so you might have to hold the phone a couple of different ways to find one that works the best at that time.

Thanks for your reply
My guess is that this issue is not related to noise cancellation.
1) I've indeed mention that, in my test scenario, my phone was in my pocket. But I can remember of several times I was holding the phone in my hand, or phone was lying on a table, and even then the sound captured by both mics was audible by me.
2) When I'm in call with another person, and I'm hearing the wind in my own mic, the other person does NOT hear the wind.
Isn't anyone here using jack wired headphones ?

Pixel 4a - Headphone Jack Max Volume Inconsistent

Has anyone noticed the max volume out of their headphone jack is typically very quiet, but at times will top out at a normal max volume? I use an aux cable to hook into my car stereo and always have my phone set to 100% volume. My Note4 and Note8 both play at identical volumes with the same MP3 files, but my Pixel 4a is significantly quieter. With the windows down, I turn my car volume up to 11 (normally) which is quite loud. On the pixel? The car volume at 18 is ALMOST that loud, but at that point is overworking the amp and degrades the quality substantially.
Here's what's weird. At random times the Pixel max volume will actually be slightly LOUDER than that of my Notes, again with the same MP3 files. When this happens, if I unplug the aux cable and reattach it'll go back to being quiet. This issue is system wide and doesn't affect just one app. YouTube, VLC, etc. all suffer from this. Has anyone had this?
I noticed it too on my 4a today when I tested it. My Nexus 5 and Pixel 1 also both had that issue also. Sometimes unplugging and re-plugging "fixes" it temporarily.
A good simple fix is to get a USB-C -> 3.5mm headphone adapter. Best Buy sells the Google branded one for like $8 - $13 in-store. I dunno how good the other brands are, reviews seem mixed when I looked on Amazon awhile ago. With the USB-C headphone adapter you'll get consistent and considerably more volume than the headphone jack. I also think it sounds a bit cleaner, too. Not much else you can do aside from some sort of bluetooth -> AUX adapter.
I have noticed this exact issue on both my current Pixel 4a 5g and even my last phone which was the Zenfone 5z. It's almost like the phone will switch gain from high to low when plugging in headphones, but sometimes will fail to do so resulting in a higher level of volume and scratchy audio. I may follow advice above and try a USB C adapter. I have not found a fix in software for this issue. The only "resolution" is to replug the headphones in until you notice the output volume is lower/cleaner.
Yeah. I can agree with lower volume. But i have one more problem after plug jack. When in song coming to louder parts, my player stops. Theres no notificiation about ears damage or like that. After that i need to press play and then its quiter.
Someone have simillar ?
The headphone jack is not very powerful on this phone, it's something like 0.3v? You need to use a DAC or buy a phone with a better headphone jack... the gold standard has been LG (RIP) and even iPhones back when they used to have headphone jacks. Now it's Samsung but they seem to be dropping whatever ports they can too.
I don't know how about you, but think they finaly fix this issue with new update. Nowy my jack works fine. Someone can confirm ?
