    I have a Plantronics 925 and when I receive calls on my bluetooth, fairly often the caller says they can't understand me and I have to call them back. There are a lot of other people that seem to have this problem as well:

    Do you have this problem? Or is your bluetooth working perfectly for u?

    My wife's varies from inaudible to bearable, with the Jawbone ICON. I have the same exact setup and have no complaints from anyone, except from her at times. She also has a bad issue with the proximity sensor and mine is not as pronounced as hers. Maybe she has a total lemon??? May have to exchange it when she gets back.

    I'm also getting the same problem with my iP4. Using a Jabra car speakerphone, which worked just fine with my original iPhone. Now callers complain that the audio quality is a lot worse.

    both my wife and i have the same problem, but it happens when we switch to BT on an active call. Once hang up and call back its fine. Almost seems like the switch from using the handset to the BT doesn't fully commit over and you can hear the person through the headset but the phone microphone is still in use.

    I have the 925, and when I first paired it to the iPhone 4, I had the same issue. Unpaired the two, deleting the earpiece entirely from the phone, did a reboot on the iPhone (home button + on/off switch), tried again. Better, but not great. Followed the same routine a second time and the problem cleared itself. I get an occasional garbled word, but nothing like what I was experiencing before, and I haven't had to repeat the process since.

    Might be worth a try. The same headset was fine with the original iPhone, so I know it's not the headset at issue.

    I'm also testing the Motorola Motorokr Bluetooth speakerphone setup this afternoon; a preliminary test last night worked decently, but the volume on the receiving side was pretty quiet. It was clear in both directions though. I need to do some more extensive work with it today to see if there are adjustments needed.

    Good info. Just to clarify, I only have this problem when I RECEIVE calls and answer them with my bluetooth. The only other way I've been able to reproduce it, is if I switch to speakerphone and then back to bluetooth it gets muffled. I've confirmed this numerous times by calling my voicemail and listening to the recordings of when i switch between bluetooth and speakerphone.

    I'm glad others are seeing this problem. I hope it gets fixed soon! (And I hope it's a software problem and not a hardware problem!)

    Yes, similar issue with BLUEFUSION car kit. Muffled/underwater sound, but not able to pinpoint when it happens. It seems mostly when I switch from handset to BT or when I answer a call during another call. But it seems random and getting to the point where I can't depend on BT even working.

    Trouble is, I also have the proximity issue so holding the phone is risky as well.

    These phones are stricken with definite design/software issues.

    As stated above, this is emerging as a software issue regarding mic priority. iOS4 seems to have introduced some issues with switching to/from the BT headset mic from the main phone mic and back. The result is sometimes audio is being transmitted from the wrong mic.

    I had the muffling problem. I also had the problem of the phone disconnecting the bluetooth all the time in my Audi A4. Called Apple last week to troubleshoot and they sent me a replacement phone. Seems to be working fine now, but there is sometimes a delay for the phone to auto-connect to the car.

    Let's hope more of the media picks up on it, and soon.

    The Motorola Motorokr sounds fine on my end, but callers are getting a lot of excess noise on theirs. So that's two for two on Bluetooth sets in our house having issues with the iPhone 4. Can't see buying another headset, since it seems to be a software issue with iOS4, and since this individual phone has none of the other typical problems, I don't want to exchange it if I can help it.

    At least the Plantronics 925 is mostly behaving after the reset.

    Contact Apple about this problem!!

    If you have not yet, please contact Apple about this problem. When I called to advise someone they had no idea of a issue with Bluetooth connectivity.

    oddly enough as i said above my HX1 will not function with the iP4 but when the phone is paired with my car (11' 328xi) the bluetooth works great. no idea what the correlation is between my headpiece vs the car.... :confused:

    well according to the giant thread on apple's discussion forums there some correlation between the noise cancellation features on certain bluetooths interfering with the same noise cancellation feature on the iphone 4.

    while in the car i've been using a tethered earpiece and mic in the meantime.. a little old school but it does the job for now.

    I have a Motorola S325 and, while I haven't had the muddy audio problem when answering calls with it, I DO have one of the other issues the slashgear article mentions: inability to stream music. Quite often, I'll power up the headset, launch the iPod app, or Slacker, or Sirius XM, and the find the audio is playing through the iphone speaker.

    I can EVENTUALLY get the headset recognized, but it takes a few tries of power cycling the headset.

    Same issue. Motorola H17. Very annoying to have to call everyone back.

    Week 27 32gb

    Genius said he had never heard of the issue.

    Apple engineering has indicated that the garbled audio is due to some BT headsets that have echo cancellation ate not correctly telling the iPhone to disable it's echo cancellation. Plantronics 925 is an example. Plantronics at least has acknowledged the issue but the fix is going to be 'buy a new headset' as far as they're concerned.

    Apple maybe able to offer some relief in software but they seem to be washing their hands of the problem.

    Why would a bluetooth device need to request the iPhone to disable noise cancellation - shouldn't this be the default setting for bluetooth devices?
