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.

Ok I just downgraded using the Python script (very easy if you follow the steps correctly)

Will give a report tomorrow after full day of use.

Thanks

You for real? Adaptive sound control is off. Never used it. I'm on Android

First listen back on 2.0.0 in an office environment. There’s a definite improvement with voices. I had a colleague make a phone call next to me and I couldn’t hear a thing. This is much improved over 4.1.1. Excellent!

1. If you don't know what you are doing I would advise against it, as you may end up bricking your headphones.

2. Probably best not to discuss the procedure on this forum, better to discuss it on the original reddit post.

So far after downgrade to 2.0 I have also noticed voices with ANC on are more subdued.

But apart from that overall performance is the same.

Thanks
