Identified playing object
_ Pulsar
Pulsar is Spirit's all-black headphone. It has an aluminium frame and four drivers that guarantee speed, precision and impact in sound reproduction.
BUY NOWPulsar distinguishes each instrument, reveals details and represents music in depth. Like the star from which it takes its name, it reproduces pure sound, capturing its spatiality in a unique way.
Pulsar is an open back headphone. Its technology conducts air through the ear cups, shaping a natural sound. It is equipped with a high-performance cable.
Pulsar is Made in Italy, built together with an ecosystem of small, high-quality companies. It smells of the finest leather crafted by the masters of Naples and travels in a wooden box that protects it and shows it off in the best light.

What is a pulsar, and why is it important?
When a massive star, slightly larger than our Sun, exhausts its fuel, it contracts until it becomes very small (a small planet a few tens of kilometres in diameter) but very heavy (about a million times the weight of the Earth). Above all, it becomes composed solely of neutrons, the heaviest element in the atom.
A neutron object, in itself, would be invisible. However, a neutron star can become visible under two conditions: if it has a strong magnetic field or if it rotates around an axis that is not aligned with the south-north direction of the magnetic field.
In the first case, particles escape from the poles, causing the plasma surrounding the star to oscillate, which emits electromagnetic radiation at all wavelengths. In the second case, the radiation emission becomes visible in the night sky, in a way that resembles the light of the Lanterna di Genova: a continuously emitted rotating beam, even if an observer can only see it occasionally.
What does a physicist and musician expect from headphones called Pulsar?
A Pulsar emits at many wavelengths, with extremely polarised radio emission; in other words, the magnetic field vibrates with great precision perpendicular to the direction of motion.
Sound is a pressure wave, so it makes no sense to talk about polarisation, but the Pulsar headphones should be able to reproduce very “pure” sounds in a technical sense, i.e. with few perfectly identifiable harmonics.
Above all, returning to the lantern metaphor, the Pulsar would be able to capture the directionality of sound in a unique way, reproducing each instrument in a symphony orchestra almost spatially.
If that were the case, it would be a dream come true.

Pulsar is the result of a process involving various industrial sectors, from precision mechanics to additive manufacturing, from chemistry to leather goods, from electrical engineering to carpentry, in an ecosystem of Italian specialists that includes 11 major companies in addition to Spirit itself. Building a Pulsar requires 140 components, 19 different types of materials, 5 hours of assembly and 100 hours of running-in.

Pulsar reproduces sound in a powerful, fast and material way. It offers extraordinary dynamic contrasts, making it ideal for enjoying music in a quiet place, capturing every detail. Its strengths are its dynamic impact, three- dimensional soundstage and precision even at high volumes. Dynamic impact is the ability to reproduce explosive sound.
At this level, the frame must be inert to the accelerations of the drive – like a good pen, a good headphone must also be heavy. Soundstage means listening as if you were in a theatre, imagining the place where the musical performance is taking place and perceiving the space through sound – seeing in three dimensions with your ears.
When the volume is turned up, the structure of the headphones is stressed and the materials are put under strain, so the materials must incorporate mechanical resistance to deformation and resonance – unlike a musical instrument, where the frame acts as a sound box, the perfect headphones reproduce sound without modifying it and do not contribute to the colour.
