Headphone volume imbalance?

It's quite possible that the default headphones that came with my vibrant are defective, but I noticed that one earbud is substantially louder than the other.
In particular, the earbud that has the mic inline on it is the one that is louder. I'd say it's maybe 30% louder than the other earbud. I ever tried swapping them in my ears to rule out if I might be going partially deaf in one ear
Does anyone else have this issue?

yea I got my vibrant about 3 days ago, and I have noticed the same thing. I may call customer care or go up to the store to get it looked at or exchanged.

I noticed that too, those headphones sucked anyway for listening to any music/movies. I cut off the one side without the mic and now use it for a wired handsfree device for when i'm driving.
PS - My other headphones work great so at least it's just the headphones.

[Q] Can't use headphones with inline mic

Hey,
for some reason, I can't use the microphone on any earphone/headphones with an inline mic. The audio output is fine, I can hear the sounds through my earphones. The mic, however, does not work. The main play/pause button on my earphones work as well, but the volume buttons don't.
Weird thing is, even the earphones that come with the G2 does not work, this is obviously a software problem. Is there a known fix or is there an app or something I can download to fix this problem?
Some specific problems:
sometimes when I am calling someone and I use my headphones, the mic on the phone stop working. I'm assuming the phone detects that an earphone with a inline mic is plugged in, thus turning off the one on the phone, but obviously this just ends up with them not being able to hear me at all.
In the sound recorder(where I have been checking whether the mics were working or not), the recorder doesn't detect my mic on the earphones, but it "hears" everytime I press a button on the inline mic which is interesting.
Hopefully someone has gotten this to work. I'm running CM 6.1, the specific earphones I'm trying to get working is skullcandy 50/50s (which is meant for iphone, but i've heard that iphone earphones work too). Any help would be appreciated,
Thanks.

That's been an issue for some people. My old wired headset that came with my Cliq does the same thing - audio mic is bypassed and mic on the phone is used instead.
The wired headset that came with the G2 works fine for me though. Tested it every which way with my wife on the phone and always got audio with the headset mic.

skeptical, I tried using the one that came with the G2 again, and magically it worked. I know that the whole audio/mic thing is still buggy, I probably tested it before when it was acting up. Looks like a lot of people are having success with skullcandy's FMJs so I think i'll go try them out.

I had a similar issue and I heard that wired headsets (iphone compatible) work on Stock, so I nandroided and went back to stock from Cyanogen and the headset mic worked fine, so it might be a cyanogen specific issue.

Headset - Earphone Problem

Hi all...
My daughter has a ZTE Blade that I flashed originally to a custom rom running Froyo... for Xmas she got some new headset in ear headphones (one's with a mic)... The sound through these when plugged into the Blade is similar to listening to music underwater (muffled and echoing).... if you press the mic button the volume increases but is still poor quality. However plug in a normal earphone 3.5 connector (two bands rather than three) and everything sounds fine... I tried the earphones on other phones/computers and there is definitely nothing wrong with them. We also bought a second pair for my other daughter and they were exactly the same, I then tried my supplied Samsung Galaxy SII headset... again same thing... muffled and echoing sound.
So the problem was with the phone.
I decided to re-flash the phone this time with a Gen 2 Cyanogen Gingerbread rom... I tried the audio again after flashing and it seemed to have been fixed (admittedly I only played a track for a few seconds). Over the course of the day my daughter has reinstalled her apps etc... went to listen to some more music and again the same problem... muffled and echoing sound - pop in some normal headphones and everything is fine.
I have searched around and the problem seems to have come up before a few times but no one has really been able to track down what the issue is. I was actuallt thinking it might be app related (Skype or Tango for example) but I have stopped (not uninstalled yet) these apps but it makes no change.
So it seems that the Blade will not work with any wired headset/mic - any idea's please?

I found it wouldn't work with a headset that has a mic on it, but I got it working fine with my £5 jvc gummi headphones although I'm not getting much in the way of sound quality and volume. Still miles better than the stock headphones in the box though

I know this is an old topic but I found the solution and some others may have the same problem:
There are two kinds of connectors, they have ground and mic signal switched.
If you get the wrong one it will work but sound (mostly speech) will be very bad, this results in a very poor audio quality.
So just get the correct ones (Apple-Style) with mic or the ones withour mic will also work fine.

cm9 bad sound through headset

Hi
Just flashed coldfusionx 4.0.4 latest version.
Everything is fine except really bad sound through the headset when playing any audio!
Sounds like extremely high virtual surround sound or listening far away in a well!
I tried adjusting dsp manager, settings etc.
Still the same. This makes everything unlistenable!
How do I fix this

Update:
If I push the headphone jack all the way in, the sound is weird
however if I hold it halfway through the sound is coming perfectly though only through one of the phones.
Anyone?

Not the ROM problem. Probably a loose connection at the phone or the earphones end

Definitely something to do with the rom.
Tried with 2 different headsets....also flashed CM7 instead and the headset sound is fine!
Flashed again with coldfusionx cm9 and same problem again.

I found on my Blade that only one type of earphone connector will work fine, if the connector is plugged in fully.
There are two types of earphone connectors in case there is a mic present:

For my blade only "Apple Style" worked fine, else sound quality is very bad. Also all earphones withour mic work fine.
Maybe there is also some rom rependency, I dont know, i use SS.

In call microphone issues when using headphones

Does anyone else have the problem where the other person can't hear you when you use a pair of headphones while in a call? When removed, they can hear me fine. I'm hoping that this is a software issue that can be resolved in an update. If not, then i want to return it before my remorse period is over.

I am having distorted sound - other party hearing it unclear and distorted..
looks like a hardware issue.. tried with 2 earpiece... no luck.

I'm actually starting to wonder about that. It may actually be a software/driver issue. I was on the phone yesterday and decided to do some testing. Unplugging them and plugging them back in provides perfect audio to the other person for a few seconds before going back to garbage, as does muting and then un-muting the microphone when in a call. Something I've noticed about the microphone is that the gain seems to be set too high - try to make a recording of cars going by - guaranteed clipping (don't have the volume too loud or you could blow out the speaker you're listening to it on).

I ran into the same issue. However, the headphones I was using didn't have a built in microphone. I discovered that if I plug in headphones that lacked a built-in mic, the phone switches its internal microphone's gain to the gain it would use if you were holding the headset to your ear. I held the microphone in close proximity to my mouth and that solved the issue.
I guess this would be a software issue.

That's exactly the testing I did and exactly what I was thinking. Now to wait for LG or Google to fix it.

Another experiment you might try would be to put your finger over the secondary microphone on top of the phone and see if that makes a difference. (My guess is that the reason your voice comes through softly with the headphone plugged in is that the phone is still doing background noise suppression, which works by taking the difference between the main microphone, which picks up your voice plus ambient noise, and the secondary microphone, which mostly picks up just the ambient noise. When your mouth is far away from the phone, your voice is equally loud in both microphones, so the difference doesn't yield much voice signal. If your voice comes through louder after stopping up the secondary microphone, that would confirm this explanation for the problem.)

Next time I'm in a long phone call where I am using headphones, I'm going to try that. It could be possible.

This appears to be what is happening. The top mic is doing noise cancelation for the bottom mic.
I called a friend and plugged in headphones. When I didn't cover either mic, she said I was quiet (because the phone thought I was background noise). When I covered the top mic, she could hear me fine.
At this point, I'm inclined to say this is a software issue because the phone app can switch between microphones and which one is used for background noise cancelation. (Putting the device in speaker mode appears to use the top mic only.)

That's good confirmation -- thanks for running the experiment. Maybe I'll put a little wad of putty in the car to stick over the top microphone while I'm driving!
