Acoustic noise cancellation is a very challenging project. It is most effective on low frequency sounds, less effective on higher frequencies like speech.

Having retired from a long career in pro audio, it's not surprising to me that Bose, a company with a VERY strong engineering department, is a leader with that technology. About 40 years ago, I evaluated a Sennheiser headset on a commercial flight. They are another industry leader.

After reading the article in this weekend's Wall Street Journal about the
improvement in Active Noise Cancelling earbuds, I am curious if anyone is
using them for contesting.  If so, I am curious as to which ones you are
using, how you connect them to your radio (a K3 in my case) and how they
compare to over-the-ear phones like the CM-500?  Since I normally wear
hearing aids, I am curious if you can wear them with your ear buds (I
usually take them off for contests anyway).
