cruncher....one of our planes has probs with DC headsets but no others.... mine are Flightcom, no complaints but Ive only had em 2 yrs. Has gel ear seals and all, no probs in any plane Ive flown and was about half the cost of the DC's.
IMHO dont even consider altronics....all our hire headsets are altronics... i guess you get what you pay for!
