No, the topic is the new noise-cancelling headsets UA is introducing --- as the thread title reflects. A true noise cancellation system requires the second pin power, making it less useful to take home.
It is technically wrong to apply the term cancellation to a passive reduction production - a passive system noise does not cancel noise by phase reversal. Klipsch does not use the term canceling rather isolation or reduction.
As far as the total net effect on noise, some passive reduction systems do perform better than some active noise cancellation (But the passive systems are more sensitive to fit and will block out external voice communication - FAs - a perhaps undesirable feature).
concerning the Meridians - not much detial
Meridian's headsets address these challenges with advanced noise cancellation and balanced sound engineering. Dialogue and special effects stay clear, music sounds natural, and long-haul listening remains comfortable hour after hour
