Narrative:

Problem: on landing, gear was unlocked but up. Contributing factors: busy cockpit. Did not notice gear down and locked light was not on. Discovered: gear up was discovered on landing. Corrective action: was unable to hear gear warning horn because of new noise canceling headsets. Recommend removal of 1 ear piece in landing phase of flight to allow audible warning devices to be heard by pilot. The noise canceling headsets were tested by 3 people on the ground and all 3 people noted that with the headsets active that the gear warning horn was completely masked by the headsets.
