Sennheiser debuts its latest premium headphone for the discerning audiophile, the HD 700 ($1,000). Featuring 40mm Duofol transducers, the headphones have a wide frequency range covering 10 to 42,000 Hz allowing for crisp highs and deep, accurate lows. The detailed sound is a result of the drivers being mounted in a stainless steel gauze that helps lower distortion. Available this March.
