Technics premium wireless over-ear headphones feature high-resolution audio quality, hybrid active noise-cancellation technology, and intuitive ambient sound enhancer. The expertly developed diaphragm has achieved high rigidity and high internal damping. The result is a powerful bass that seems to soar from the bottom depths and a spatial ambiance that makes you feel as if you were in a concert hall. The bullet-shaped diaphragm dome has realized improved rigidity. The linear high-frequency characteristics provide a smooth and lustrous sound. The rib edge was optimized through simulation to attain high linearity across the entire input range. Delicate nuances of music and realistic dynamics are faithfully reproduced. Detailed simulation and fine-tuning were repeated to achieve an air control precision structure that results in optimal airflow. The two carefully designed ports and original construction create an accurate airflow to bring out the wide-range frequency reproduction capability from the driver. Technics F70N wirelessly deliver pure sound, just like the artists are performing live right there with you. It realizes high-resolution, high-quality sound, and reproduces the subtle ambient acoustics within the music. Ready for major high-definition formats such as LDAC and aptX HD, so you can enjoy high-quality sound easily. The outer parts are made of aluminum. The alumite treatment and spin finish bring out the high-grade ambiance of the material. The Technics logo mark is laser-engraved and colored. Every detail reflects the high-grade design. The hybrid noise-canceling system combines two different systems to realize high noise-reducing performance - the feed-forward system which uses a mic mounted on the outside and the feedback system which uses a mic located near the driver positioned close to the ear. In addition, the circuit was originally designed to provide improved noise-canceling performance.
