+4 at 1600 Hz and +10 at 2400 Hz are rather aggressive and may
contribute to the excess sensitivity to breath sounds.  I'd be
looking at +3, +5 (which represents 3 db/octave) or +2, +3 (close
to 2 dB/octave) instead of the almost 6 db/octave your settings
represent.

Even the most aggressive of the "articulated" (aka, "DX") mics don't
have more than 6 or 7 dB boost at 3 KHz.

73,
