Well putting aside the marketing hype why do they make audio equipment that produces sound outside of the normal hearing range?
"Humans have a maximum aural range that begins as low as 12 Hz under ideal laboratory conditions,[2]<http://en.wikipedia.org/wiki/Hearing_range#cite_note-1>to 20,000 Hz in most children and some adults, but the range shrinks during life, usually beginning at around the age of 8 with the higher frequencies fading." http://en.wikipedia.org/wiki/Hearing_range#Humans My theory is that by producing sounds outside you are adding back in harmonics in an attempt to more accurately reproduce the sound at lower volume. I only base this on my observation that the brawler the range the lower the volume I need to enjoy the music. If this is not the case ( as I can not prove it either way ) then a good $22 pair of headphones ( now assuming a good sensitivity of => 105dB/1mW ) is all you should ever really need.
