I also have used the Bose for about 3 1/2 years on the North Sea(Fairley demanding environment). I feel it is by far the most comfortable having started on peltor and tried DC as well. the ANR bit is superb but i agree that if the bat fails then it goes back to the old Peltor standard.
I understand although i have not tried it that Bose along with good ear plugs is the ideal solution but i havent tried that.
