The Pro-X takes up much less space in my kit bag, is subjectively more comfortable on long legs, and is $300+ less than Bose with really good support.

Crew Outfitters will have DC sets to try out, but buy directly from DC to get the airline price.

What equipment has LEMO? I'd say get XLR and carry an XLR to Dual Plug adapter for those times you jumpseat on Boeing or whatever.
