I have two: Bose X and the Telex ANR 1D. The Bose is probably the better one, not by much though. The reason I didn't go straight to the X was the $400 difference, the fact that the ANR unit of the Telex can be powered by 4AA and/or a cigar lighter input. The Bose is also a bit lighter than the 1D.
I have used headsets with electronic add-ons, but am not really impressed. It depends how much your hearing is worth...
