Hi jdoherty76,

I'd personally have a look at the benefits of the update then decide accordingly. I've had a look in on the latest version of this headset and can see that it's mainly adding Alexa and Google Assistant features. You can have a look at this here:

I've also heard from a couple of users regarding the NC and battery issues after the update but I also know other users who didn't face any problems after updating. Hence, I don't really think that this is due to the update. Otherwise, all users should've faced the same exact problems.

Hope this helps,
