Do check but I seem to recall that the advertised price of the Bose X is around the $1450 mark these days.
And I enjoy using my Bose X. The batteries seeem to last about 35-40 hours of life and my ears do enjoy the quiet. It is a lightweight, comfortable unit. I clip the control unit to my pants leg with the clip provided.
The only thing that irks me about the X is that for the price the headset bag is not as good as the el cheapos. I now use a bag that has space for the headset but also has compartments for fuel tester, licence and ASIC and maybe spare batteries.
Mr Bose please take note. The carry bag needs to be improved along the lines above.
