That's not correct. Headsets, Inc, sells a complete ANR headset for $399,
The kits to convert most headsets into ANR's are $169.

I purchased two sets of ANR headsets. One was an expensive model. The
other was a private labeled model made for Pacific Coast Avionics, which
sells for about $250. I use that one all the time and the passenger gets
the expensive model.

I see there is a ANR box that can be added to any headset. However, it is
$399 only for the adapter.

I am happy to leave my David Clarks in the drawer and use my $250 ANR
units.
