CES 2007

Sennheiser’s PXC 450 ($499.95) headphones are both the new top model in their noise-canceling series and the first using the Talk Through technology, which distinguishes between general ambient noise and the voice of a person talking to you. I tried them briefly, and was impressed both by the sound quality and by the acoustical isolation. They’re modeled here by Nicoll Public Relations’ Erika Pearson.
