I flew with Clark's for years lol...I know I know.
I went with the Bose and Fly Mic...it was awsome. They have a great payment plan so I think I was paying like 50$ a month. Funny thing however soon as I bought them I switched jobs and now if I were to wear a headset I probably would get funny looks.
Never dealt with Bose customer service so I have no comment on that.
I use my Bose now only for my commute so no one bothers me and they are awsome. I rarely get the "hey shouldn't you be up front or how are you going to fly from way back here".
