The Koss QZ/99 that I have are NOT active noise cancelling. The QZ Pro 
apparently are electronic active noise cancelling phones.

I am very happy with the performance (comfort, audio quality, and 
outside noise isolation) of my QZ/99. No batteries to go dead. If you 
are familiar with Koss Pro 4AA stereo (high-fi) phones, these feel 
similar, are lighter, and have much greater outside noise blocking to 
the ears. They look a little like David Clarks although not green.

In their most recent catalog, AES has the QZ/99, QZ/50 and the QZ/2000. 
QZ/50 is an active noise reduction unit which uses a AAA battery and is 
only $50. The QZ/2000 is also an active electronic noise cancelling 
headphone, running on 2 AA cells, but closer to $180.

You may be able to buy the QZ Pro directly from Koss, or from some other 
audio or ham dealer.
