How common are cyberear enhancements?
The book makes out cybereyes being fairly common, but just wonder how many people spring for audio enhancements.
And with this would there be there a genre of music catering to folk with the ability to hear a range higher or lower than the norm?

While an admittedly small market, it could have its appeal in some circles.
