I have no belief in burn-in being anything but mental, so I use them straight off. If it was really a thing, manufacturers would do it before shipping.
Anyways, I was referring to switching between my current set of headphones.
But enough with the OT
I've never seen anyone complain about the sound changing for the worse after "burn-in", but if you say so :)
I know from experience that I mentally adjust when i change my main headphone, but it requires a couple of days.
Well in my eyes they seem ***** footed about the whole issue, information has to be pulled out of them on an individual basis and posted back here.
I'm guessing they want to avoid a full recall, even though it sounds like all units are affected.
Of course, I might be biased by the fact that I couldn't even get a response from CS.
So in other words they confirmed that this is a hardware design flaw affecting all the current M2 AEBT headphones sold, but that they will not do a full recall because not enough people trigger/report the bug.
