I just purchased the 700 headphones and so far I love them. I do have one concern. When ANC is turned off or at a low number when I rub my finger on the microphones on the earcups it makes a loud scratching noise. Does not do this if ANC is on. Is this normal? I am on the latest software and use a iPhone.
Regarding this issue, this isn't something that I've heard of. I would recommend a reset. I have included a LINK HERE to assist you with this.
Let me know how you get on!
