Hi-

I'm 52. I cranked it up through my stereo, and I could hear down to the 24 year old (18khz) if I cranked it up very loud. At normal volumes I could hear 15k clearly.

I bet most PC desktop systems can't even reproduce the more high pitched notes. So those of you who couldn't hear above 14khz or so, it may not be you. I know the published specs say they can reproduce to 20khz, but they probably can't, or not at a volume you can hear the tone.

My Logitech PC speakers are rated 20khz, and I could only hear 14k through them, even with Shure in the ear earphones plugged into them.
