Thanks Arjay,
Pretty high then given an EM272 is ~14dB. For the price I'll order a couple as they're <?1 each. But I hold no expectations.

So this capsule has a noise figure of c.24dB.
Note that this figure is 'A weighted', which will normally tend to 'flatter' the actual noise figure a bit.
Not that special.... ( gives some idea of where that kind of figure stands in the 'range' of mic noise figures ).
