Yes, you pretty much have it backwards.

Active noise reduction only affects what you hear, not what you
transmit - it takes place in the earcup of your headset. "Passive"
noise reduction refers to the ability of the headset to attenuate
noise from the cockpit, again so you dont hear it. Either ANR or
passive noise attenuation will improve your ability to hear
transmissions.

Note that active noise reduction and passive noise attenuation work on
different frequency ranges - high frequency noise is best reduced by
passive attenuation, while low frequency noise is best reduced by
active noise reduction, so all ANR headsets also passively block high
frequency noise.

However, there are also noise-cancelling microphones, which will
improve the quality of your transmissions. Most good headsets will
have these, independent of whether they are active or passive headsets.
