Unique Semi Open Design: Get the best of both worlds with the combined benefits of both open back headphones and traditional closed back designs. They balance and reduce ambient noise, while still providing a natural sound, with clear separation, transparent highs, accurate mids, and full driving low frequencies. Exceptional Bass Response: New 53mm diameter large drivers pump out ultra low, deep bass that will please the most demanding listeners. Style and Comfort: The high quality leather headband offers both luxury and durability, while the soft velvet honeycomb ear caps provide plenty of comfort for extended listening sessions. Quality Craftsmanship: Brushed aluminum sliding supports provide a robust, yet sleek foundation for these premium headphones.
