Lizzie and Antoine,

Thanks so much for your input.  I could only access the 'T=C3=A9l=C3=A9char=
ce fichier' link on my Mac using the browser 'Opera'.  It would not
work in Firefox, nor in Safari.  But I did finally get it!  Yes
Antoine the noise is the same loud fizzing and popping that I was

Antoine, you ask, has a solution been found?

All I know is what Syntec in Sydney, Australia, have told me.  When I
first had the noise problem they said that Sennheiser in Germany DID
know of a noise problem with MKH 8060 and 8070, but that they DID NOT
know of a problem with the 8020s.  So we have to assume that this is
a NEW problem for Sennheiser, at least for 2011.

Syntec verified that there was a problem by taking an 8020 mic from
their stock, and testing it, and it was noisy.  They said "Sennheiser
in Germany have made suggestions for us to investigate, so as soon as
we have done that investigation, and come to a way to resolve the
problem, we will be in touch again to make sure you have some nice,
quiet mics !"  From this investigation (presumably squeezing the
sides of the mic, see below) Syntec were able to analyze the cause of
the noise, they think.  Sennheiser is replacing the batch of 8020
mics that were sent to Australia and hopefully the problem will be

But we just won't know for sure until we try them.

Lizzie, yes I am sure you will get one of the 'new' batch of 8020s
supposedly due to arrive in Sydney about Oct. 12.  You could email
the Product Manager at Syntec in Sydney, he was helpful in my case:

Syntec have this morning received my 2nd faulty set of 8020s which I
returned to them.

Antoine, apparently this problem is not only with the batch of 8020s
that were sent to Australia, it must be worldwide.  I am surprised
more people have not spoken up about it.
