Hi,

I bought the Sony WH-1000XM3 in April 2019, but didn't update the firmware because of the issues with NC and related issues which people reported. Have the issues been fixed with later firmware updates? Is it worth upgrading or should I  leave it on the original firmware? Call quality was an issue, and I haven't used it on calls because of this,so if a recent firmware has improved things, it would be tempting to upgrade. Not if NC has got worse or other issues will creep in though.
