I'm merely pointing you to the website that everyone is using as evidence the noise cancelation changed between the versions of the firmware. It clearly states there was no change between 2B584 and 2B588. It does say that 2C54 is much worse than 2B584 (and 2B588). This is a site that many on this thread are using to validate their claims. The site uses equipment (not ears) to measure actual performance.

Perhaps, but the website that is being used to support claims of ANC reduction in 2C54 is clearly stating that 2B588 did not affect ANC. If the website is incorrect then their tests should all be reconsidered as valid evidence of ANC degradation.

You're the one misleading people since what you are broadcasting is personal here say while the above ling points to methodic testing.

According to the website responsible for the testing results 2B588 did not significantly reduce the ANC. 2C54 did.
