The Bose X is the best headset around by a big margin.
If you can afford it, it's worth the money. If you can't afford it then...
I have four of them.
But it's not something you can lend to careless people. It's not built like a tank. If you want something for club use, and generally kicking around, get a £200 David Clarke. They are crap but they will take the abuse of everyday GA usage by people who think a headset is £20.
Don't buy a used one though. Bose had a problem with the mikes, from about 1999 to about 2003. They still work (better than other headsets) but not as well as the current model.
