Work pretty well on an airplane. Slight electrical hiss when noise cancelling.
Decent sound, better lows than highs.

great product. greatly reduces the amount of background noise when noise canceling is active. is is especially good for low frequency sounds eg when in a bus, on a plane or in a car.

We have thrown them in a drawer with all the rest of the junk we have purchased. They do not work as the package claims they will. Even with the noise cancelling feature. We tried them for about 2 months at B***** and N***** because we sit next to a knitting group which gets very loud. We have to turn the volume way up for us not to hear them as they get louder and louder. We are looking at other headsets to see if anyone else has a better set without costing and arm and a leg. Sorry but your headsets do not work as described.

Pretty mighty little guys. They cut off low frequency noise only and you truly notice that immediately after switching to ON. So, you still hear voices of those around you, telephone ringing, etc. They pump rather clear sound, a bit weaker than generic ear buds, but surely wider in the scene. I would say these are worth the try. I will definitely test them in the subway and on board the plane some time later. Recommended for use.
