How durable are planar magnetic headphones (LCD X)? Dropped off table

[headchiq]

My pair of LCD-X fell of my table and hit the ground from about 4 feet or so. They sound fine. I'm just curious if durability is something I should worry about with planar magnetic headphones?

My Sony MDR700 drivers from a decade ago still work great.

I guess it depends on the build quality. The driver itself is between two magnets, so if the overall construction isn't wood or plastic, it should be fine. For example, Abyss guys drove over their AB-1266 with a jeep in one of their Youtube videos and the headphone survived, haha.
