Most headphones are relatively straightforward. They're usually built around a simple metal or plastic frame, have leather or pleather ear pads, and if you're lucky, are comfortable. Hopefully they sound good, too. What they aren't, usually, is bendable or droppable. Nor do they have Kevlar-coated cables, steel frames, or military-level testing.
That's exactly what makes the M-80's so unique. That military testing certainly means they're durable, but with a $230 price tag, you would hope they sound great, too.
