Abstract
A canalphone system may include a canalphone housing, and a low audio sound-tube to carry a low audio signal to the canalphone housing's outside. The system may also include a high audio sound-tube to carry a high audio signal to the canalphone housing's outside, the high audio sound-tube phase corrected with respect to the low audio sound-tube by sizing it to be longer than the low audio sound-tube, and the high audio sound-tube's length is greater than 3 millimeters but less than 10 millimeters.
