    The call quality problem seems to be with the phone on the other end of the call. I have not had this problem with call quality until this day when someone with a Sony Xperia Z called me. The call quality was so bad that I had to listen very carfully to understand what the person said. One moment after I got a call from another friend who has an iPhone, the quality of that call is crystal clear. So I think we should stop blaming this on the iPhone itself, and maby look at what phone is used in the other end of the call.

    I have it very often and even when other side has Iphone. It is a real and huge problem. I know so many people with Iphone 5 having this problem. Maybe you have a good iphone, then you are lucky. I have the problem in 20% of the phone calls, it is more then annoying ...

    I have talked to alot of guys who's got the iPhone 5. None of them are having the problem. Most of them live around the area. I think the error may lie in some cell towers. HD voice just got realesed here in Norway on Telenor, did not hear about the problem until then...

    May sound like a stupid question but has any one tried putting their SIM card into another iPhone 5 to try, I haven't tried this yet just curious to see if anyone has tried this. I'm on my second iPhone 5 and I'm getting really frustrated with apple not giving any reply as to why so many people are having the same problem. I don't think the next ios update will fix this problem either. Hope someone can help. Thanks.

    Actually, calling from iPhone 5 to iPhone 5 results in the same bad quality for at least one user. So I'm still blaming the iPhone. Bad batch from the factory? My hardware specs are (according to http://www.chipmunk.nl/klantenservice/applemodel.html):

     

    Model Number: MD297

    Generation: 7

    Production week: 49 (December)

    Model introduced: 2012

    Factory: C9 (China)

    May be the iPhone, I personally think it is a cell tower/codec problem. The iPhone is not the only phone with this kind of problem.

    Through some research and experimentation, I've found a possible partial solution:

     

    After Apple replaced my iPhone 5 in November (I'm in the US, and my carrier is Verizon), the incoming audio for phone calls was noticeably better but still plagued by drop-outs, robotic-sounding noise, muffled effects, etc. as others on this thread have described. Last week, I found that changing this setting helped me:

     

    Settings > Music > EQ > change setting (from "Off") to "Spoken Word".

     

    I know this setting will change the tone for music/etc. but I need my iPhone much more as a phone than as a music player. For phone call incoming audio, the resulting change in sound/tone is subtle (and not objectionable). More significantly, I've found this change improves intelligibility when listening to the other party on a phone call, and it's now much less fatiguing for me to understand what the other person is saying. Also, other parties now say I sound a bit better to them; that is, the audio outgoing from the phone is a little clearer, too. While I use a wired headset most of the time, I've found these improvements apply even without a wired headset (although I haven't tried Bluetooth).

     

    For sake of completeness, here are a few other thoughts I've found _may_ be valuable to consider:

    1. During a phone call, be sure all 3 microphones are not obscured (there's one microphone on the bottom edge, one on the front by the speaker where you'd put your ear, and one on the back between the camera and the flash). So don't lay the phone flat on a desk, but instead prop it up to ensure the mic on the back is exposed to air. Also be sure the mic on the bottom edge isn't obscured; periodically taking off an external case to remove any accumulated lint would seem prudent.

    2. If you're going to move the phone away from your head, be sure to use the speakerphone, Bluetooth, or a wired headset. If you skip all three of those options, be sure to orient the phone with the bottom

    edge toward you. If you orient the phone with the display facing you squarely, so that the top and bottom microphones can both pick up your voice roughly equally, then the noise cancellation algorithm is likely to suppress some of your voice when you speak to the other party.

    4. The noise cancellation algorithm can take several seconds (even 10 or 15 seconds according to some reports) to adjust to a new noise environment. When working from my home office, which is admittedly rather quiet, and having changed the EQ setting as describe above, I've found the algorithm does fine after just a few seconds.

    5. Replacing the SIM makes to improve the audio makes no sense to me, and most reports I've seen (particularly on this thread) suggest it's a waste of time.

     

    "Your mileage may vary" but I hope this change to the EQ setting may help others.

    Unbelievable, UPS was at my doorstep this morning with a new iPhone (already!). I haven't made any calls yet, but will let you know if my problem was resolved.

    Have somebody tried with IOS 7 yet? I have also the boring robotic voice problem. Have they fixed the problems?

    I was having problems with my Iphone 5 on vodafone in Australia. I put up with it for a few months but decided to send my phone back to apple and they sent a replacement out to me within 5 days. Worked well for a couple of weeks and now the annoying bad call quality has returned... I can hear the other caller perfect and they cant hear me... then they can hear me and i cant hear them... then neither of us can hear each other!!! **** it apple FIX IT!!!

    I don't think it is a provider problem !

    I am in Belgium and here have the same problem with the Iphone 5 (IOS 6.1.4)

    The call is each time corrupted for 1 sec, and the voice on the other line is almost

    unrecognisable.  I heard they could fix this with a new update, so I hope it comes soon,

    the Iphone 5 here in Belgium costs around 700 Euro !!  For this amount I would really

    appreciate a phone that works good.

    There seems to be a lot of different call quality problems discussed here.

     

    My problem (and many others in this thread) has been.

     

    * Robotic/clipping sound in the Iphone

    * The receiver hears everything good.

     

    The workaround has been to shut of 3g/lte. Then it has worked good.

    I had the problem for half a year and it has been hundreds of times i have asked people to call them again. It has been extremly tedious. I switched phone onc with the same result.

     

    However. That bug is finally fixed in IOS7 Beta 1. Finally. Yes!! A lot of other bugs. But not that one

     

    Pretty critical bugs like:

    -Impossible to answer sometimes.

    - Dropping the line when you got an email while speaking. etc.

     

    I guess they will fix that in the next release. But the sound problem is gone!
