40 mm Dynamic Driver with Newly Developed Diaphragm
This diaphragm is consisted with newly developed composite performance film (CPF) laminated with a plurality of special materials and it 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 ambience that makes you feel as if you were in a concert hall. To maximise the effects of these characteristics, the shape of the diaphragm was designed with utmost attention to detail. The special bullet-shaped dome has realised improved rigidity. The natural and linear high-frequency characteristics provide a smooth and lustrous sound. The rib edge shape was optimised through simulation to attain high linearity across the entire input range, from weak to large input. All delicate nuances of music and realistic dynamics are faithfully reproduced.
A Precise Air Control Structure
Detailed simulation and fine tuning were repeated to achieve an Air Control Precision Structure that results in an optimal air flow. The two carefully designed ports and original construction create an accurate air flow to bring out the wide-range frequency reproduction capability from the driver.
Hybrid Active Noise Cancelling – 3 Modes
The hybrid noise cancelling system uses two different systems: the feedforward 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 cancelling performance.
High-grade Materials
High-grade Materials The outer parts are made of aluminium. The alumite treatment and spin finish bring out the high-grade ambience of the material. The Technics logo mark is laser-engraved and coloured. Every detail reflects the high-grade design.
3D Ball Joint Mechanism
The ball joint mechanism allows three-dimensional movement of the ear cuff to fit the ear at a comfortable angle. The ear pad is made of soft, low-resilient polyurethane foam.
3D Ear Pads
The shape of the ear pads is ergonomically designed and low-resilient polyurethane foam is used inside the pads to ensure a snug fit around the ears. The ear pads offer increased isolation and sound insulating performance as well as extra comfort.
Swivel and Fold Mechanism
The swivel and fold mechanism makes it easy to carry and store the headphones.
