Make high-performance audio completely portable and personal. Acoustic equalization and TriPort technology produce superior, natural bass without bass boosting. Highly-efficient drivers produce big volume even from wimpy preamps in portable players. Advanced ergonomics; lightweight design; soft ear cushions; thin, adjustable headband; and swiveling earcups make them the most comfortable high-end headphones ever. Great visual appeal with slick-looking design and high-tech finishes.
