I've got the same problem, and with TV monitors, as well.
Last time I tested, I could hear above 23KHz.  While using
one particular set of terminals I had to use ear plugs.  If
you have to resort to this, try using the little foam cylindrical
ones.  Thery're very comfortable.  Now, I just use a portable
CD, which seems to mask most of the noise (and monitors seem to be getting
better, in general, and I suppose I'm starting to lose high 
frequency response with age).

BTW, who ever thought that 22.04KHz frequency response was adequate
for CD's?
