I'll give a detailed report on my one time speaking with Bose customer support in the 5 years of my ownership of the headset.
I had owned the headset for about 4 years at the time of incident. I was on the road doing Aerial Survey and I noticed the ANR would cut out and then come back on randomly. I called Bose support for the Aviation X headset (Seperate support #), which was fantastic because there was no automated system, just a human answering. We spoke on the phone for some time trying to diagnois the problem for the issue I stated.
I told Bose my situation of being an on the road, aerial survey pilot. I told him I would need to headset to be inspected, fixed and returned as quickly as possible. I'm from Massachusetts, Bose is in Massachusetts however, at the time I was in Dallas, TX for a project (KTKI). He told me to ship the headset to Bose, overnight. I paid out of pocket for the shipping which was approximately $60.00. I shipped the headset out on Wednesday night. Thursday morning I called Bose to verify they had the package. The same individual I spoke to previously answered this day too. He informed me the package had arrived, they would diagnois, fix and overnight ship the headset back to Dallas that day so I would have the headset Friday before 10am. Sure enough, about 9:00am the Cutter Aviation FBO at KTKI was calling my cellphone to inform me of a package that was there with my name on it from Bose.
I looked over the repair report. They replaced a driver/mic/pcb assembly, yoke left, yoke right, pin/hinge, two new ear cushions, 1 new wool head cushion, and at my request put a high force torsion spring in to make sure the ear cushions would stay secured around my ears. This high force torsion spring is a special spring bose has for guys that are flying in an loud interior environment. It's supposed to keep the ear cushions firmly fixed around your head to ensure the ANR is functioning to its best ability. I have not noticed a difference in "clamping" between this high torsion spring and the stock one.
All said, $60.00 out of my pocket. headset shipped on wednesday pm, I got it back friday am, fixed and ready.
Not too shabby Bose!
