Hi-Xcursion (High Excursion) technology is the key to the astonishing sound the Hi-X60 headphones deliver. All Austrian Audio Hi-X headphones feature a 44 mm driver and a ring magnet system. This design allows for improved airflow and includes the strongest magnetic field in its class. The ring magnet, combined with a copper-clad aluminum voice coil, reduces the weight of the membrane and the voice coil connected to it, allowing the membrane to move or change direction faster, providing a more responsive impulse reaction. Recording, Mixing and mastering with the Hi-X60 headphones is an absolute pleasure. Expect great bass imaging and low THD (total harmonic distortion) at low frequencies, together with a linear frequency response and open, precise high resolution sound that is very revealing and makes error detection easy.
