Emily,

They're expensive, heavy, and require batteries.


Look again - at all of the factors you mention.

Expensive? You can get excellent ANR at a price below the passive DCs.
Heavy? Pure BS. The top-end Lightspeed is lighter than the passive DC,
not to mention the featherlight Bose.
Batteries? well, tere is one model powered of the mic power, there are
on-board powered variants, and the battery models run 20 to 50 hours on
2 AAs. Who cares?


The top-end Lightspeed, the 30-3G, is around 16 ounces, with some of the
middle-grade Lightspeeds weighing in at around 20 ounces. Quite a bit
more than the DC 10-13.4, at around 13.4 ounces.

Batteries are an inconvenience, but the battery life on most ANR sets
these days seems to be decent. There's always the panel-power option,
though that removes the flexibility to move the headset into another
aircraft.
