We are receiving a number of reports from Sony Xperia Z1 owners that are complaining about compatibility issues with headsets. The Sony MH1c headset is bundled with the Xperia Z1 in a number of European countries, yet many cannot get the two to work.
Once the button of the headset is pressed it brings up the Smart Connect notification. Therefore users cannot change the volume or answer calls using the answer. We understand that this problem is not only limited to the MH1c headset, but others too. We expect Sony to fix this bug soon, so we’ll keep you posted. If you’ve suffered from the issue let us know in the comments below.
