I agree. I don't want to be neglected by customer support should there be an issue with the QC700. @pemerick07 suggested the QC700 because of the call quality.

BOSE? Whats wrong?? Give us a downgrade option until you sort it out??? How hard can it be?? What is taking so long?? Why you make us wait??? You will not force us to buy the new 700 by letting us wait like this.....
I suggest that everyone on this thread contact Bose at their customer support number. For the US it's 1-800-379-2073 and reported this issue. I think if the customer support gets flooded with all the issues with this firmware, that will make a difference. I called them to report an issue with my iPhone dropping from the Bluetooth and reconnecting on its own. I also informed the rep about the firmware update 4.5.2 and the loss of ANC quality. She made a note of it. It was suggested that I go to btu.bose.com and do the firmware update from there. I will not do that since mine already has the 4.5.2 firmware per the app.

We have looked into this extensively for you and have escalated this to our engineering team. They have been able to confirm that no changes were made to the ANC functionality in the most recent update. That said, we want to make sure we are supporting those who may still be having issues and may be reaching out to some of you directly for more details to support a continued investigation.
There are a number of troubleshooting steps you can take regarding ANC that can be found below: We encourage you to review it for a potential solution.
