I have a small qty of EM158s left. I'm in the process of ordering another
batch this morning.

There are a few recordings at:

The last time I was out at night recording frogs I placed a pair of 158s on
each side of a tree truck and then placed a pair of 183s on the same tree
about a foot lower than the 158s. I alternated between the pairs recording
into the same RH1 recorder.  Just from listening with my Sennheiser HD 280
Pro headphones it seemed that the 183s were a little more sensitive and the
158s self-noise was a little lower.

Eric is still running tests but he stated a few days ago that it appears
that the freq. response of the 158 at the high end is a little better than
shown in the Primo spec.

Do you mean "EM158?" :-)!! Thanks to Gene Dorcas (tip on this list
9/2005) we've been using these caps with HiMD in my field audio class
this Fall. We should have a number of comparison tests to share by
the end of the semester.

I concur. Eric has some tests that he may be readying for release.
The EM158's seem to be on par with or perhaps a little better
noise-wise than the Shure WL-183's; a tad less sensitive. The 158's
are only ~6mm in diameter-- considerably smaller, less massive and
even easier to mount than 183's.

I believe Gene has them for sale in several configurations on his
site. I'll wait for Gene to confirm this before I drop his link.
Eric Benjamin plans to test the EM158's powering needs more
carefully. Rob D.
