Ok guys my headphones (Meelec M9P) make static when I plug them into my phone. It's starting to get really annoying. When I plug it in I hear static that gets worse when I touch the screen, but it reduces drastically when music or sound gets puts through it. My Jetblue $2 airline headphones (no mic) don't do this...
This happened on all roms, but I'm running the zomg not my dog build of Froyo.
The reason one pair of headphones does it while the other is because the one that does hear static has a lower impedence than the one that does hear static.
But the explanation behind it getting worse when you touch the screen is similar to the what sometimes happens on old PCs with cheap integrated sound. Sometimes you can hear static, and hear more when moving your mouse or when your CPU load is high. It's caused by something like signal interference within the hardware, and there's nothing that can be done... which is probably what's happening to you.
I'm using Head-Direct RE2 earphones, but the impedence is high enough that I don't hear static.
Sorry, but I think there is nothing you can do to remedy the static =/
Just did a quick search: indeed, your impedence = 16 Ohms (source), mine = 32 Ohms
This happens to me too, its really annoying and makes the phone feel like a piece of $hit!!!!
Well actually you could use a mini headphone amp like this one I have and like
Fiio E5
and it would probably solve your problem since it will be between your headphones and the phone
But don't you think it's stupid that we would need something like that?
I only have that problem when I'm plugged into the car charger. DC vs AC I guess.

actually AC is noisier. it has a sine wave, DC does not. your wall charger still spits out the same DC as the car charger, it just rectifies the ac to dc before stepping the voltage down. Car charger is all dc so its just stepping the voltage down from 12v to 5v. car charger probably has a weaker ground. Most car chargers I've seen are poorly built...
i thought that was normal
i got some sony MDR-V150's and i get that **** too yes i know they're old! so dont say anythin bout that
its not very loud but since i got good hearing plus the fact its right on my ears i can hear it when nothin is playin or when i touch the screen
Question for you guys: why do you put headphones on when music is not playing

I'm using M9P's, and they use a mic so I can take calls with them also, and I love using voice command with them .
Ahhhh the impedence problems seems right, but I wonder what the impedence on crappy airplane (Jetblue) headphones are then? I think it might have something to do with the mic, but there were ways that would slow it down. I could "turn" on the headphones without plugging it in through an app called toggle headset. It removed a lot of static, but sometimes it didn't work...
All of meelecs phones' are 16impednece, which makes me believe that when I get my m11+'s they'll have the same prob
No headphone pop or capacitive screen static
The static with touch screen issue has been addressed. It was a problem with any OC Kernel, but it has been fixed with the latest kernels Darch has been putting out.
CyanogenMod RC1
Has anyone else noticed an issue with the Iconia a500's speakers emitting a rather high-pitched, noticeably audible sound while you're charging your tablet?

Some user had the same issue awhile back, only not so loud. My guess, some sort of protection tape came loose (yes, Acer uses a lot of tape on the inside). Either that, or a grounding point is loose on the inside.
If it's under warranty, send it back.
If not, pop the back off and poke around a little. There's some guides somewhere in the general or q&a forum. Also some you tube vids if you search.
Also, dirty electrical in the house/apartment can cause this as well. If you have a really good power strip with noise filters, you can try this also. Or go to a new facility and plug it in there and see if it's the same.
Other devices do the same thing.
Every time I charge my ipod or iphone in the car via car charger while having it plugged into the aux to the car speakers, it emits a high pitched sound through the car's speakers. It seems to something inherent.
The solution might be simple as not using the speakers while charging your tab. But I guess there are ways to fix it as Moscow stated if you feel adventurous.
Anybody had this problem? Seems to completely go away when I stick the device on it to charge, but is quite audible otherwise when plugged in.
Hi, recently my Nexus refused to charge. I mean it was said it's charging, but percent was always the same (even when turned off). It turned out that it was an issue with usb charging port. So I've bought a new charging port, which is also merged with headphone jack port. Anyway after replacing old charging port nexus charges fine. However later I've been watching youtube video on it with sound on speaker. Every small move disables sound. It looks like it's getting "inserted headphones" event all the time. How can I fix this except buying next charging port? I've found two apps which can toggle between speaker and headphones, but problem is it's changing all the time so I probably need something with endlessly forces my nexus to stay on speaker. I don't use headphones anyway. And my device is rooted which may somehow help.
Regards
Anyone help?
I'm not sure, but maybe it's a issue with flat cable. Some time ago, I didn't put the flat cable well in my board and in headphone I hear only the left speaker
My S4 is randomly detecting a headphone (even though it's not there), the notification comes and goes. The port still works with no problems whatsoever but as the device's screen turns on every time a headphone is detected it's eating a lot of battery. Can the issue be singled out to be only the jack?
While the phone may have been exposed to rain (accidentally, as it never left my pocket), I've read that if it was water damage it would just show to be connected all the time, is that right? I tried to fix it with q-tips, plugging/unplugging the headphone with no sucess. I've noticed that plugging it in the charger makes the notification appear/reappear.
I'd say it's the headphone jack.
