I've recently bought the Sony WH-1000XM3 and was expecting there to be a quick mute function on the headphones rather than having to go to the laptop or phone application and mute within that. I'm very disappointed that there isn't!

I have a cheap headset on my office PC that has a physical button on the headset which I regularly use and is very convenient when in conference call and there is noise in the background that otherwise gets picked up by the mic.

Surely this is a function Sony can add into this headset!
