I go off-roading quite a bit. Lots of wind and engine noise. I use my QC30 to cancel out the noise. It does a pretty good job. I was thinking to get another one for my navigator and was wondering if it would be possible to set the QC30s up to support peer to peer voice comms on iPhones. Has anyone attempted this? If so, what app have you tried. Bose, if you are listening please consider adding this functionality to your Bose Connect app. Thanks.
