Sony WH-1000XM3 - v4.1.1 firmware failure?

[GapsOfTheGod]

Having updated my 1000xm3's over the wekeend, there seems to be an introduction of hiss and a background noise of what sounds like distant traffic (even though I can hear nothing at all without the headphones on) when using Active Noise Cancellation, which was previously stellar. The potency of the noise cancelling is noticeably weaker since updating (I'd estimate around 40% less). Familiar auditory environments which were previously rendered almost entirely silent are now notedly audible. I've checked that the noise cancelling slider is left-most, and indeed it is.

I'm also disappointed to find I can't ask Alexa to play music from Spotify, and I press the button and just say "Play Metallica", it responds with "Shuffling music by Metallica on Amazon Music", yet nothing plays at all.

This update is very much a downgrade as it stands.

Yeah, Sony loves our conversations.   Oh, the irony of it...

Sony Finland support:

" I got more information from our technicians, and they said there was no difference in the headset since the last update. For this reason, we cannot guarantee that the headphones are under warranty for this, but you can, of course, choose to send our headphone to Infocare at our service center if you feel that the headset has something abnormal"

Good luck with that, I got mine returned from Infocare with label "no errors found".  Your hope is with your retailer, exchanging the set to obtain customer satisfaction.

Well fortunately I got my headphones with th stock 2.0.0 and had internet connectivity issue while the upgrade process. As I was lucky not to update it the 4 firmware version 

As I found this thread I will for sure stick with the current firmware until future firmware STABLE releases

Really disappointed with Sony's way of managing their customers. Could issue mistakes and publish a fix firmware.

Hi. About the question regarding what firmware version the xm3 currently have. I bought 2 yesterday at Bestbuy in Miami USA. One in black and one in gray. Both still have firmware 2.0.0.
I hope this information is helpful to those who asked. Greetings.

What's the production month? It's on the bottom of the box.

Could you please explain how to read a label on the bottom and find the production month?

Thanks

Eh I was in an electronic store a few days ago, there was a sticker on the bottom / or side, with a date on it: 02-2019. So I assume it was produced somewhere around February but I can’t confirm. Maybe you can find a date somewhere ? Could be at a different place.

I can see only the label with serial number..
