I've had a Bose headset for just over three years and I have never had an issue. The only thing I have replaced is the ear muffs due to flying in hot weather in Florida and they get sweaty. The material started to break down. It was my fault because I should have cleaned them more regularly. This happened after a year or so and I was flying around 5 days a week for at least 4 hours a day.
I love them. I have tried on the lightspeed ones and they are nice too. I prefer the Bose ones though. The bluelink attchment looks pretty cool but it does add a lot of extra expense. I think I may invest though.
Asian rotor hunter; why were they so bad? What type of operations does your company do? Maybe you just got a bad batch!!!
