Poor magnetic shielding

Hi all looked through the forum but can't see anyone else mentioning this.
When i have headphones pluggged into my Desire there is a noticeable hissing noise coming through them (I have a pair of fairly expensive Shure headphones) which seems to come on and off depending on whether the phone thinks it should be outputting noise. Anyone else noticed this? Was dead silent on my Iphone.
Anyway, as per the title above, when i am listening to music etc through the headphones in addition to the hiss i have just described i can hear the phone connecting to the network. Not sure how best to describe the sound sorry but it's like the one you get if you put your phone next to a speaker while you're making a call. It's not particularly loud but is extremely annoying. It's intermittent and seems to mainly occur when the phone is using GPRS or Edge.
It also occurs when i receive a call with my headphones plugged in.
Has anyone else experienced this or can anyone else test this by listening to music through headphones and browsing the web or similar?
I'm assuming it's down to poor magnetic shielding but want to see if it's just my phone or common to the Desire in general.
Cheers

No problems here using my Shure SE210 earphones. Whisper quiet using Meridian Player for both Videos and Music (FLAC).
Have you tried the earphones you get with the phone, or indeed other earphones? Just to try and isolate the problem...

I also have Shure SE210 and I rather don't use them with the Desire. The static level is just over the roof! What's more I also dislike the sound as a whole, it's tiny. I guess an equilizer could relieve this.

So has anyone else noticed this issue?
I use Shure SE210s too. But my point was they worked absolutely fine on my iPhone - this is why I believe the problem to be down to the phone hardware not the headphones. I can live with the slight static but the phone buzzing noises are unacceptable.

Hi,
I have the same issues (GPRS/EDGE noises). With any headphones I use, I can hear the phone accessing the data network. The problem is gone, when I'm on wifi. May this be related to custom ROMs and kernels? I really want to get this fixed

OK, I fixed it. Apparently I had the "only use 2G networks" option turned on! Now with 3G the issue is gone

Reviving an old thread here, but just wanted to say I have this problem with a pair of Sennheiser CX300's and Creative Aurvanas. Airplane mode doesnt help at all. As long as the phone is outputting sound, it's hissing. It lasts about four seconds after it has stopped playing sound. It is being retunred tomorrow, after HTC claimed it was not a known problem with the phone, and told me to try and return it.
The same earbuds work without a problem on a Nokia 5800 (Xpress Music "Tube") and an iPhone 3G. If this is a problem with all Desires, mine will be returned for my money back. You can't advertise a phone as a heavyweigth media phone with such a MAJOR flaw.

This hissing noize you talk about which is only 4 seconds long also happens on my iPod touch, so I don't think its a massive problem

The hissing noise is present all the time while the phone is producing sound AND four seconds after. So I would say it is a pretty big problem.

The Desire's Radio Interferes with Head-phones?

Hi there,
I didn't believe it at first, but the GSM / 3G radio on my Desire interferes with the headphones while I listen to music, to the degree that it is, well... unlistenable. I have to activate the Airplane Mode in order to listen to music, which I think is just preposterous. I've never had that problem with any other phone.
You know that annoying noise that cellphones can induce in stereo speakers, if the speakers are connected to an unearthed socket? That's what I hear in my headphones on the Desire.
Is this due to a unique fault in just my unit, or do any more of you hear this noise?
Cheers

I hear it only when the internet connection is active - and even then it is quite low (but still there).
So all I have to do is turn off internet connection and the problem is solved.

Hi i'm glad someone else has noticed this thought it was just me
here was my thread about it:
http://forum.xda-developers.com/showthread.php?t=683024&highlight=shielding
Definitely seems like poor shielding to me. I can't believe nobody else has noticed it. Maybe because I use sound isolating headphones so it makes background noise quieter?
A very serious flaw for something I use as my main Mp3 player

Someone at your thread wrote "Apparently I had the 'only use 2G networks' option turned on! Now with 3G the issue is gone". I am actually on the countryside at the moment and unfortunately required to connect using GSM / Edge, perhaps that's what causing the noise and it will disappear on 3G? Either way, it shouldn't be there in the first place

Just under that option is the option to turn off mobile internet...try that instead, at least you still get phone calls and messages that way.

I just replied in the other topic. I have this problem withg several in.ears, and disabling internet or enabling airplane mode doesn't help at all. As long as the phone plays sound (and for four seconds afterwards - ie, as long as the "soundcard" in the phone is turned on) it makes a hissing sound, making it completely unfit for music and to some degree tv series/movies too.
edit: Guess I should mention that the volume is also too loud, there is NO way I can have it more than two or three steps from the bottom, and between the lowest step and "silence" (ie. only hissing) there is quite a jump in dB.

What product are you using? I've only noticed this on products of poor quality. Both my AKG and MW600 have no problems with it at all.

As I said in the other thread, I'm using a good quality closed headset and there is no hint of hiss.

I have the same problem with a pair of Creative Aurvana in-ears and a pair of Sennheiser CX300. While they are not the most expensive sets you can buy, they bot sound fine while used with other devices - ie. a Nokia 5800, an iPhone 3g and my old Creatove Zen Micro. It is most certapnly the Desire that is the problem.
I expect to hear noise wih low ompedance in-ears on cheap laptops and non-branded china players, but not on somathing claiming to be a great multimedia phone at a pricetag of $620 (unbranded in Norway).
This prolem most likely stems from bad intrnal isolation of the audio chip/wires/jack, and would ofc not be heard with a BT headset... As to your AKG, unless they are low impedance in-ears, whether you hear noise in them or not is equally uninteresting.
I would really like someone with a good pair of low impedance headphones and good hearing to say that their phone is NOT producing this white noise. My pal didn't think his did, but it sure does. If it is just faulty units, it means it can be fixed, so I don't have to spend a few months getting my money back and find another phone to buy.

Headphones buzzing sound

Not sure if anyone else is experiencing this but I have a buzzing sound in my headphones in the left ear. It is fairly loud when the phone is idling. When I switch apps or screens it goes away momentarily then starts again. I have tested it in the music app and it does not appear to be an issue while playing music. I checked some very low volume sources and its not there. Still I wonder if I have a bad unit or have something activated doing this. I am completely stock new AT&T LG G3.
Update: After testing a few more sets of headphones, this only happens on my Bose QC15s which have the noise cancellation. Its interesting though that the Bose are dead silent on my Galaxy S5 and my wifes iphone. I tried both cables with them (since one is designed for idevices) but it doesn't make a difference. Not sure what interference they are picking up but I think I will take them to an AT&T store this weekend and see if it does it on their display models.

Is it anything like...

I think it's the same thing. With the Bose it's like a humming buzzing sound. I don't hear it at all with the Apple $79 IEMs. They are listed at 23ohm impedance. With mine it's as if theorizing switches on and off though. I can switch apps or play music and its dead quiet after I immediately pause but then it clicks back to buzzing.

Same here, Bose QC20 LG G3 D855... Left Channel buzzing.
Do you think it's a defect of the phone?

I was almost returning my G3 and i was like "Hell no, again..." , i have exchanged my nexus 5, 5 times! and still has the same problem!

One interesting thing I will note guys, when I plug my headphones in that I hear a buzzing sound, I get the headphone icon in the NB. When I plug in the Apple headphones that I cannot hear the buzzing sound at all I get the headset icon in the NB.
I have read this is a Kit Kat 4.4 issue but I did not have it at all with a Galaxy S5. I am hoping it will be fixed soon but I am thinking about grabbing some different headphones anyway.

I have the buzzing just listening through the earpiece on the phone itself, no headphones required. I have the T-Mobile D851 model. So one would theorize that this is also using power since it's powering the earpiece to make noise. Some kind of electrical interference in the phone itself would be my guess.

Hi. Just got my UK spec G3 in the last few hours and I've just come across what I believe is the same problem. There is a distinct buzzing/crackling/static sounds when I have headphones connected via the 3.5mm jack. The sound is only present when I have certain media playing (using Spotify at the moment). I only notice this when connected using the jack and not when using my Bluetooth receiver (HTC BH S600). I did hear this while using two pairs of earphones while they were directly plugged into the device, the LG QuadBeat 2s from my G3 and the in box headphones from my old HTC One M7.

This has to be a software problem. I was just testing again and the buzzing becomes stronger in any app I use just when I touch the screen and scroll. I hope this is an easy fix in a custom rom. Also as I reported earlier, I do not have the buzzing during playback. I know this because I have tested some very quiet tracks and also checked on some very long gaps between songs. If it is humming it is much quieter. Only when I exit out of the Music app it is immediately quiet then it clicks in at about 2-3 seconds. I have also had a few quirks today where my headphones come up with the Aux Icon then after pausing the Music app a few times they switch to the Headset icon.
Not really sure what is going on but there has to be a software fix.
I will say the Music app sounds unbelievable with Viper4Android installed. It definitely has more oomph than with Play Music. Comparing the same tracks in both apps back and forth, the Music app is cleaner. Not sure what LG has done in that app but I like it.

I only get a buzz during charging. Disconnect the charger and it goes away. Most devices I've owned have the same issue recently. S4, S5, note 3, moto maxx, moto X, nexus 5 have all done it to me but only while charging

I have a really nasty popping crackling sound in between tracks when using aux in my car, but headphones no issues... Never had that problem at all on my nexus 5 so it can't be my head unit in my car

I wanted to post an update to this problem. I originally reported I had this issue with my Bose QC15 headphones. I do not have this issue with my Apple In Ear headphones. Today I was diagnosing things again and had been listening the the Apples. The Apples always correctly have the headphone icon show up in the Notification bar. When I plug in the Bose, I always get the Aux icon. This got me to thinking about if the cable was different. I pulled the cable out of the Bose and on the end that inserts into the headphones themselves there is a Hi Low switch. Mine was on high. When I switched it to Low, the G3 started to recognize them as headphones and not show the Aux icon. The hissing and buzzing immediately went away and its dead quiet. This switch is an input level switch and undoubtedly having it on Hi causes the G3 to not recognize the Bose properly.
There is a thread about the Aux input problem and I think they have it diagnosed. Its going to take some software manipulations. I listen to my G3 in my car through Bluetooth so I do not experience any issues on that end like the folks in that thread. As for headphones, I am not having the issue with my 2 sets.

Just a little update...
Updated to V10E, issue seems to be fixed...
No more buzzing noise in my left channel...

I have this problem when I plug into the car aux port (noise in between tracks). Just a quick question, which icon should appear in the NB if I plug in an audio cable from the Aux socket?

How strange...
Sent from from my LG-D855

I picked up a D855 V10d (Telstra branded Australia) two days ago and noticed this yesterday myself.
I have Shure SE425 canals and they make the static noise when idle, very noticeable on these headphones. When music or audio is playing the static goes away. This is of course only when the charger is plugged in.
I tested it with the LG headphones that came with the phone and the noise is still there but softer, grabbed my Samsung headphones that came with my S4 and couldn't hear anything. I believe it's due to the resistance of the headphones.
Another test was to turn off the phone and charge it with the headphones plugged in, no static noise if I did this.
Going to exchange the phone today as it's unacceptable, I primarily use it at work to listen to music and often charge it at the same time.

[Q] Noise on earphones (Stock ROMS)

Hello , how are you? First, sorry for my english.
I need help, and I think that you would help me. I have a G3, and I've noticed that the earphones are making a noise when a sound is emitted. I've noticed too that this happen only in Lollipop ROMS (stock based).
I've installed Kit Kat and CM12 baseds and the noise doesn't appears. I already installed via Flash Tools and TWRP, with all wipes, but the noise persists. I've noticed the noise after I've installed the app Sound booster for G3.
I dont think that is hardware, because in Kit Kat and CM12 works perfectly. The noise happens too in all sounds of system (including music, video).
I've tested with more than one earphone. And before installing the app to boost the sound, it worked perfectly.
The noise doesn't happens in speaker.
Can you help me please?

I have this little noise too, but i note that it happens only when charging. Disappears when not charging. Probably an interference. Between earphone plug and charge

It's a fairly common lollipop occurrence. It happens in other devices too...

I've just noticed additional noise whilst music is playing (on top of the beeps when plugging in and hiss whilst no sound is playing). This noise is best describable as unwanted distortion on sound of particular amplitude, though a quick experiment just now makes me wonder whether the hardware design is bad. (AIUI G3 audio's handled by the Snapdragon MSM8975AC SOC, unlike my old Samsung S3 LTE which had a discrete Wolfson DAC).
This problem is also VERY audible on the bundled LD "QuadBeat 2" headphones, in both ears at various points. I'll see if I can get a recording of it.
Methodology:
I loaded the "Wave" signal generator app and tested various volumes - noise is evident at particular amplitudes. I set the variables thus: a 100 Hz tone, 30 seconds duration, varying amplitudes. Finally set Wave amplitude to 0.02, turned the device volume to max and listened to try and ascertain whether this noise was being introduced by the chipset or the Android OS.
Results:
There's very noticeable 'fuzz' and unpleasant distortion in the left channel, which goes away both under and over a particular amplitude threshold -- which leaves you with an annoying band of amplitude where you will always have additional noise overlaid onto the sound.
Frustratingly, this is often in fade-outs or quiet passages of songs where you're listening most intently. It also renders the G3 useless for any kind of analytical or accurate audio output, a crying shame. My Google Fu is lacking too, because I didn't see this thread before buying mine... I wonder if installing CM12 might fix it?
Unless this is a problem with the stock kernels and the way they handle audio output, I'm becoming concerned that this handset is faulty by design and I'm going to have to swap for another make. Until it died, my old S3 had great audio capabilities, and a nice chipset to boot!
I've sent a customer service request to LG specifically about this. Here's what I wrote:
I'm experiencing significant audio problems with my new G3 handset.
When headphones are plugged in with no audio playing, I hear two beeps in the left channel. Then, a low level - but constant hissing - in the left channel, until the sound chip is initialised to play audio. The right channel makes occasional warbly, 'squeaky' noise, seemingly modulating with CPU activity.
Also, since updating at the weekend to Android 5.0 Lollipop (OTA via the LG Software Update process), I have noticed that whilst playing any audio, if I adjust the device volume to around 50%, additional noise is introduced into the signal chain (audible as a dithered 'fuzz' over the audio content).
I have tested with various pairs of professional headphones (I am a qualified sound engineer) and the problems are present throughout. I am concerned that these are significant design flaws. Please advise if a software fix is available, and whether these are known issues with this handset.

I have found a workaround for this
I have tested 3 LG D855 and all of them have noise/static/high-freq leak from the processor out to the headphones. It might be a faulty design for the headphones amplification stage for headphones (when the headphones logo appears on the status bar). However, when using line level output (the jack appears on the status bar) the problem does not reproduce.
Therefore the workaround I've found is to trick the phone into line level output mode and then plug the headphones. To do this you need to plug in a 3.5mm jack extensor or a 2-to-1 3.5mm Y-adapter with no load, that's it, with nothing connected to it. At that moment, the phone will activate the line level output mode. Only after that you will connect the headphones, and you'll see there are no artifacts on the audio.
That being said, I'm not sure this will work with all kind of headphones as I have only tried with mines that are low-impedance ones, but on those it works perfectly. To be checked if the level of the signal in line mode is enough to drive other headphones.
In any case, it is a shame this happens with a high-end and expensive smartphone. I was hopping this will be fixed in a newer hardware revision but I got two replacements of mine and no luck. I have read somewhere this might be a flaw in Snapdragon 801, as it integrates completely the signal routings but isolates badly highfreq noise from processor stages, etc. etc. but I do not remember where I did read it unfortunately.
I hope this helps!

Anyone hearing a noisy headphone jack?

I often plug my phone in to my stereo system using the headphone jack.
I've noticed that when the phone is not actually playing something I can hear some little crackles and occasionally some buzzes.
I've tried it plugged in to several sources and they all show the same bahaviour, so it's not the stereo, it's the phone.
Anyone else have a noisy headphone jack?

Did you try all of them with the same wire? That could be the cause of the noise.
I've only tried mine with a wired headset and didn't notice any noise.

Yes, different wires

Good question. Yes, I tried two different 1/4 inch to RCA cables and also my 1/4 inch to cassette adapter. Also tried a different phone with the same cables and had silence.

This only happens to me when I plug my AUX cable in my car into my 5X, but it doesn't happen when I put my headphones into it.

I can hear an audible noise every few seconds when I have my headphones on and nothing playing on the phone.. No issues with those headphones plugged into other devices.
Also, my output volume is low. Need to crank my stereo up in my truck when this is connected via aux. Full volume on both the phone and truck is equal to about half when using my nexus 6.. Huge disappointment.

I have this same issue and I've also noticed that the device does not get loud enough when plugged into my cars stereo on my S5 I can the volume all the way up on the phone and keep the stereo at 25 and it would be loud enough for me but now with my 5x I have the phones volume all the way up and the stereo set at 38 "witch is the max volume for the system" and I'm still left sometimes with wanting the music to be louder so hopefully this can be fixed with a software update

Same experience here with the volume in my truck compared to my old phones

I've noticed this happening on my phone as well. It does it with two different aux cables (not when I plug in headphones, though, oddly). My roommate's 5x does it, too. Turning the screen on stops the crackling. I recorded a video of it (I apparently can't post outside links so you'll have to build the url yourself): youtube . com/watch?v=-RObC7bZcQs
The volume seems fine though.
Edit: I received a replacement phone yesterday, and it has this issue as well.

Yes, I can report the exact same behaviour.
If I put a different phone on the exact same setup, there is complete silence when that phone is not playing back audio.

Anyone find a solution to this?

I get a pop in the silent gap between every song on Pandora. I am using a Bose Q15 noise cancelling headphones and nexus 5x with marshmellow. With new batteries in the headphones and low volume 15%..

I've been noticing the same issue. It only happens when no audio is playing back and the screen is locked. When I unlock the device there's no popping until it locks again.

Ditto. Getting pretty frustrated with so many accumulating little annoyances on Nexus phones.
