Abstract:
Audio reproduction devices, including without limitation headphones, universal in-ear monitors and custom in-ear monitors, are improved by electrical design that targets a flat electrical impedance across a predetermined frequency range such as the typical audible range of 20 Hz-20 kHz. Headphones and earphones having a flat or linear electrical impedance characteristic will have more consistent audio performance when driven by different sources.

Claim (Index 3):
The personal audio reproduction device of  claim 1  wherein the predetermined amount is \u00b125% of a nominal impedance of the personal audio reproduction device.
