I have BOSE QC for years now too, but they haven't been reliable at all.
I've been lucky that BOSE keep replacing / fixing them... There was a period where they were needing replaced every 8 months or so and I like to think I take good care of my stuff. I'm not rough with them. The current set has at least been good for a few years now. All I have to do is replace the ear muff bits but that's expected and I had to replace the cable about 9 months ago.
Can't fault the sound quality though and the noise cancellation is great.
similar - went through a pair of QC20 - replaced 5 times in 3 years. rarely do we get extended warranties - my wife had read a few places saying to get it, and we did. she got a pair - no problems, but she uses them at most a few hours a week. mine, I'm wearing probably 8-10 hours per day, 7 days a week. I slept with them in, initially, but I'm sure that contributed to the first breakage, so I quit doing that.
