I think he was trying to stay away from earbuds.

I can't wear them - guess my aural cavities are too small or my treggis is too large or something.

Could be worse... we were testing out a smaller set of headsets this summer - instead of a full single or double muff with headband and a rigid mic, they had a little secret service-type over the ear setup with a wire lip mic. Ambient noise blocking was MUCH less than desired and one of the shooters asked for an earplug for the other ear and to have this thing gaff-taped to his head, so I made a big production of waving around the black tape, then as he turned his head, I slapped a big X over his ear with hi-viz orange safety tape and sent him out. The confused look when he stripped it off 3 hours later was priceless.
