Probably your ears are suffucient -- tweak the azimuth screw for maximum

Sounds like you're on the right road. You might get better
intelligibility if you use a parametric equalizer to boost 7.5kHz by a
dB or so after the de-noising has been done, which will make consonants
easier to hear, but that'll worsen the audible noise. You'll have to
decide whether that's worth the tradeoff.
Incidentally, what are you using for audio monitors?
