As I have posted before, the Bose X is the most comfortable headset I have ever worn. I have had my Bose now for more than 2 years and have put close to 1500 hours on it. In that time it had to go in for repair twice. Once for a squeal in an earpiece and once for a broken wire in the cord.
What I will say is I have never seen customer support from ANY company like you get from Bose. Both times the headset was repaired free of charge, including shipping and new leather ear pads.
Other companies can sure take a lesson from Bose.
