Planar Drivers: Not your typical headphone driver! The planar driver in the M1060C has been completely redesigned and engineered versus the driver found in the M1060. Several enhancements have been made, including a new symmetrical magnet structure that allows the planar driver to be much more efficient in a closed back enclosure. Closed Back Design: Outside noise stays out and only the music stays in! The 1060C delivers excellent audio isolation, allowing the sonic landscape to not be disturbed by the outside world, and the outside to not be disturbed by your music. This makes the M1060C the perfect audiophile choice for those that may need to listen in less than silent environments. Comfort: The Monolith M1060C has been engineered to be comfortable for extended listening sessions. Large, comfy earpads made of faux leather and a padded headband are designed to keep you comfortable as you listen.
