Introduced at CES 2009, the CC_01 is a pair of higher end canalphones from Koss. Featuring a new dial-in fitting mechanism that helps elliminate the tinny response of poorly fit canalphones and the pain of forcing them in, the user merely turns the external dial ring to have thre ear cushion expand to fit the inner ear perfectly. This enables the earphones to sound their best while allowing for the greatest comfort and isolation. Available in March, with no details on whether they will be available in the United States, the CC_01 will cost $150.
