Yes I have - and I had no idea about the issue or controversy until after the update. I was in bed one night playing with the Bose app on my iPhone. It prompted me to do a Firmware update - I use these headphones A LOT - at the time I was wearing them for 6-8 hours a day for weeks on end and was very 'in tune' to their abilities. It was very quiet in bed, I'd been wearing them while reading a book for an hour before - I did the firmware upgrade and immediately noticed a difference when they rebooted. I was very confused and started playing with settings etc. I then Googled the issue and realised how widespread it was... The report linked is super interesting, but, I trust my own ears as a musician and I know something changed with the headphones 100%.
