Not being a slave to fashion or badge snobbery I fly with a Racal Jetgard headset which I bought back in 1994; I have seen friends and other club members get through several pairs of DC's which seem to fall to bits after a couple of years. And I cannot wear Peltors as they are THE most uncomfortable headset I have ever tried.
Racal Acoustics now seem to market the Jetgard as a groundcrew headset, but mine was configured for GA and has worked flawlessly for 14 years and looks nearly as good as the day I bought it. It has never needed repair and I have yet to find a radio, intercom or headset mix that it hasn't worked correctly with. They also have impressive passive noise reduction too.
Not sure who sell these now or how much they cost, but back in '94 they were comparible in price with the cheapest DC's.
