QC 35II sound issue (lack off bass in one side and higher frequencies on the other)
I have just bought the QC35II (15th of May) on the Airport.
I have noticed that the sound is not equal on both sides.
The right side is significantly lacking in Bass comparing to the left side, and it seems that the higher frequencies are lacking on the left side.
I have upgraded the SW to 4.3.6 and performed a reset and re-pairing of devices as described in the troubleshooting and it didn't solve the issue.
I have tested the device using the following link
The problem occurs in all of my devices (MacBook Pro, LG4 and Samsung Galaxy S8)
I have also asked one of my friends to listen without telling him what to expect (to make sure it is not my hearing that got wrong), and he had pointed the same issue.
