Here is my basic understanding:
DPA 4060 =3D 20 mV/Pa
Primo EM172 (used by Teling Clip-ons) =3D 39.8 mV/Pa
However, this value is valid for 1kHz, it can vary based on frequency.

That means Primo is more sensitive. Just wanted to point out that
self-noise is not the only spec affecting the final noise figure.
