endurance test
1980-1991 1031 hours flown in GA aircraft 2 cheap headsets trashed BER.
1991-to date 2980 GA hours flown DC headset working as well as the day I got it, cost of ownership one set of ear pads.
So to put is another way you can expect about 515 hours use from a cheap headset and that headset would have to be 5.7 times cheaper to mach the cost per hour of the DC that is still running well today.
As the old Arab proverb says Cheap is not so cheap.
