"Tune out the world for under $40!" Noise canceling that works at a very reasonable price! Give Bose credit for a great idea but the "concept" is well out of the barn! These phones sound great, are very comfortable to wear, 30 hour play time and if you do manage to run down the battery just plug them into the wired input to connect the phones to the player and keep listening. Alternatively, eBay has these listed for $84.63.
