Overall Rating:

A number of other accessories such as a dual airline adapter plug, and a headphone adapter plug (1/4”) complete the assembly.The cables supplied are compatible for connecting to the Apple® iPod®, iPhone™, iPod touch® and portable MP3 players. The AH-NC732’s will also work great with your home stereo and AV systems.

The noise cancelling offered is the active type where a microphone is located near the ear of the listener to detect ambient sounds and an equal and opposite sound is emitted inside the ear cups to cancel the sound out.
