No contest for me. I've tried both, and after three hours the Bose gives me a headache. I have worn the Lightspeed Zulu for up to 12.5 hour flights without any discomfort. We have Bose on one of the company airplanes, but I take my Zulu to work...uh...flying. Work is wearing the Bose, but not everyone will agree. For the amount of money you're going to spend, better try both.
Our 185 has two Zulus. The wifey loves hers, too.
