I measured both of my NH-700s, and what this does is give you an extra
20dB of gain on hi-sensitivity. You pay for this with a 20dB impairment
in overload level - the NH-700 mic input clips at -31dBu on hi and -
11dBu on low
sensitivity measured at 1kHz

from the fact that the noise floor does not increase by 20dB on low
sensitivity although the clip level does decrease by the extra gain we
can infer that this is probably achieved by a gain reduction in the
input stage rather than a straight 20dB pad at the input, which is a
nice touch by Sony.
