real nice, but somewhat fragile
I've owned a Bose-X privately for several years. The rotating plastic microphone boom broke once. This would have been expensive (about $400), but thankfully Bose covered it under their excellent guarantee. Next time it will have to come out of my pocket. Now I'm very careful to watch how I move and position the microphone before returning the Bose to my flight bag. While the Bose-X is a great headset for private use, I'm not so sure about its suitability as company equipment. Not that people are careless; it's just not as rugged as a Davis Clark and parts like the microphone and wiring are more vulnerable to damage than most pilots would expect. I've owned three Davis Clarks for passengers for over 20 years and only ever had to replace covers and pads on those.
