IMO there are really only 3 tiers of headset: Junk, David Clark, and Zulu/Bose.

I've had a Lightspeed for my entire career with the exception of one place that, for whatever reason, required a TSO'd headset. I had a Thirty3G and now have a Zulu 2. Hands down would recommend it.
Our Twin Bonanza has an installed Bose Aviation Headset X...I care not for it, unplug it, and use my Zulu when I fly the 'Bo.
