Focal Utopia's are one of Audio Sanctuary's most exclusive headphones and offers what we feel is one of the greatest sounds that can be achieved from a an open back headphone. Used with a comparable source the Utopia offers a view into the musical world like no other. The Utopia is the reference high-fidelity headphone manufactured by Focal. They are the result of 35 years of innovation, development and manufacturing of high-end speaker drivers and loudspeakers.
Equipped with exclusive technology, they offer striking realism, neutrality, dynamics and clarity, for sound with unrivalled purity. Utopia are unique they are the world's first audiophile headphones to be equipped with totally open-backed full-range speaker drivers with pure Beryllium 'M'-shaped domes.
Made in France
Designed and manufactured in France, these very high-end audiophile open-back circum-aural headphones for low-noise environments are equipped with exclusive technology resulting from more than 35 years of expertise.
It has a pure, elegant and sophisticated design due to the carbon fibre yoke and true lambskin leather headband and ear cushions. You will forget the headphones are even there, and the reproduction of the audio signal is of unrivalled clarity.
Purity of Sound
One of the reasons why headphones sound different to speakers is due to the shape of the soundwave. Whether it's an inverted dome or a positive dome, a listening distance of an inch requires that the shape of the dome is completely redesigned to achieve a plane wave in ultra-nearfield listening. In order to achieve this, Focal innovated once again by designing a cone with a new 'M'-shaped dome.
Utopia, of course, is equipped with totally open-backed full-range speaker drivers utilising the famous pure Beryllium dome in order to offer an unrivalled mass rigidity damping ratio. Once more, the engineers at Focal have pushed back the limits of acoustic innovation and have succeeded in providing a listening experience worthy of the best Focal loudspeakers. The result: a transducer with a frequency response ranging from 5Hz to more than 50kHz without any crossover or passive filtering.
The cable supplied with Utopia was specifically selected for its capability to respect the original audio signal, such as its very low impedance (< 90 mΩ/metre). It is totally symmetrical in order to offer extremely low crosstalk (< 70 picofarads). The shielding protects it from electromagnetic interference and allows for a longer cable (4m/13 ft.). Finally, the 9.5mm Lemo connector and the 6.35mm Neutrik stereo jack enable easy customisation.
Monolayer Voice Coil
As part of the project, Focal has design the very first voice coil without former that also features a monolayer coating to make it even lighter. The result is a voice coil measuring 25mm in diameter by 4.4mm in height which is actually lighter than voice coils measuring 15mm x 1.5mm used in other highend headphones on the market. The goal is to have excellent mechanical coupling to the dome considering its diameter, and to ensure the voice coil is always controlled by the magnet's magnetic field regardless of the excursion
The surround is clearly a key component of the moving part. When it comes to the physical demands expected of Utopia and Elear headphones, the surround needs to offer an optimized compliance and have high Xmax, to ensure they are as lightweight as possible. Once again, Focal has proved its expertise with another world premiere: the thinnest suspension ever created, with a thickness of 80 microns! This challenge required months of work to conciliate very low mass, maximum excursion and the linearity of the moving assembly, all while ensuring perfectly balanced sound regardless of the volume.
