#1 has rattle, (on "how to plan and manage", both before & after), #2 doesn't have rattle.
On second thoughts, I think the rattle is mechanical, being generated in the microphone, as it's faintly on the unprocessed audio. Lowering the pitch is bringing it down from 12kHz-14kHz where it's barely audible, to 10kHz-12kHz where it's subjectively louder. Then the treble-boost makes the rattle even more conspicuous.
So the rattle originates in the mic, but is being made conspicuous by pitch-shift down, and treble boost.
#1 & #2 there is too much de-essing : the volume dips noticeably on sibilance and those parts sound muffled.
The de-esser threshold set to low for that "essential items" audio.
