Abstract
A canalphone system may include a canalphone housing, and a first high frequency driver carried within the canalphone housing. The system may also include a second high frequency driver carried within the canalphone housing where the second high frequency driver is tuned with the first high frequency driver to deliver lower distortion than a standard canalphone high frequency driver and/or lower distortion than two standard canalphone high frequency drivers that are not tuned with each other.
