ANR Headset
I've put three batteries into my Bose X (~120 hours inflight time). I've gone half an hour on three flights before realizing I forgot to turn on the noise cancellation as the headset is quieter than my old DCs.
I bought them because they were best for me. I got to try the various other headsets (ANR DCs, Denalis, Lightspeed, Sennheiser) as students bought their planes with those other sets installed. It was a toss-up between the Sennheiser and Bose until I closely examined the Sennheiser and took em on a flight test. 1. That little wire holding on the earcups wouldn't last in my flight bag. 2. They are heavier than the Bose.
For customer service, Bose installed the microphone assembly into the right side BEFORE shipping my headset, only because I asked. If I had a problem with this set, I know I can call, email, or talk to their reps at a tradeshow (talk, not scream), and my problem will be solved. Like any company, I'm sure Bose has bad eggs working for them. The solution is to end the call and call back. So far (2 months), the headset had held up well with zero problems.
Next report at 1000 hours head time.
Fly SAFE!
