I'm a Zulu guy. The Bose actually hurt my ears after a while because they press on the ear instead of going around it, which I prefer.
The Clark's are the most durable by far but also the most uncomfortable.
The Zulus are a bit more delicate and that bugs me. Have to treat them like an egg. The Clark's you could drop out of your plane on the way by the hanger and they'll prob be just fine.
The comfort, blue tooth, and music quality is why I stick with the Zulus.
Haven't tried the newest version of any of them tho.
Really good if you have a friend that'll let you borrow the different ones for a flight. You'll know right away. Like most things, the price savings of a cheaper one is not worth the long term discomfort of dealing with them in my opinion. Save a Lil longer if you have to...
If Zulu and Clark had a baby, that'd be the headset I'd want.
Good luck.
