Narrative:
I'm writing this to bring up a point concerning the new headsets and the oxygen mask. I had always worn the old ear mold and never had a problem donning the mask. I picked up my new headset 1 day before this event took place. We had the cabin warning horn go off at FL330 with the cabin climbing at approximately 2000 FPM. I grabbed my mask and promptly tangled it with my headset. Could have been a problem with a rapid depressurization at FL410! I had to remove my headset and untangle the mask to get it on. With the warning horn blaring; thunderstorms; and in the dark; it is not a good time to discover this problem. I would strongly recommend that people practice the procedure with the headset before they really need it.
