I've got Bose-x which broke (mechanically) after 12months, Pilot 17-79 which fell apart after 15 months, a pair of Peltors which still work after 5 years but the volume control is broken and A DC 10-60 which is 17 years old and still going strong.
If you do very little flying and like to pose - get a Bose. If you want a near bullet proof build quality that will last then get a DC. The 13.4 was not available when I bought mine but I have used one and would certainly recommed them.
