Valkyria is an open dynamic headphone, driven by a powerful twin pulse isobaric motor with revolver drive for absolute control of diaphragm movement. Given the exceptional weight/power ratio generated by 40 neodymium magnets, arranged to concentrate the magnetic flux on the moving coil, the four drives push the motor assembly to capture every sound detail, right down to the threshold of audibility.
Valkyria is characterized by its extraordinary analytical capabilities, exceptional acoustic resolution, dynamic range, and high-volume precision. The speed of sound transients allows each instrument to be distinguished even in the most intense orchestral passages. Valkyria owes these extraordinary qualities in particular to its titanium frame, as the exceptional rigidity of this metal allows for impressive acoustic focus and positioning. The metal architecture undergoes an anti-reflective and anti-resonant treatment made with a combination of materials including Dynamat Xtreme. Valkyria is designed to ensure maximum comfort thanks to its soft headband and weight distribution, compatible with the specific weight of its structure.
The Twin Pulse Isobaric System motor unit is the first isobaric system applied to a headphone. Two high-performance drivers, connected in series, move in synchronisation across the entire audio range, allowing the airflow from the ventilation ducts to be channelled quickly. The results: excellent acceleration times; halved mobile unit excursion, limiting distortion and dynamic compression; doubled power load; doubled 64 Ohm impedance for easy driving with a wide range of amplifiers.
The pads, developed based on the Spirit design by industry leader Dekoni, incorporate the Ventilation Pad System 4.0, an additive manufacturing architecture that ventilates the ear chamber while maintaining optimal heat and humidity levels. The structure, completely redesigned in 2025, is combined with a new driver configuration that once again changes the standard for Spirit's top-of-the-range headphones. The substantial improvement in sound goes in three directions:
— Three-dimensional external sound stage
— Extended frequency response in the sub-bass range
— Greater ease of driving with tube amplifiers
The Valkyria cable, lightweight and highly flexible, deserves a separate chapter.
The signal is carried by a fully symmetrical double-wiring structure consisting of a perimeter braid made up of 16 pure silver cables and a coaxial OFC copper core cable per channel, for a total of 36 cables soldered with silver solder directly to the revolver drives, so as not to lose efficiency in current transport.
Valkyria travels with a solid walnut wooden case inlaid by master cabinetmakers and designed by Spirit. The headphones and case travel in a wooden box for maximum protection.
