Focal-Utopia-HeadphonesFocal Utopia headphones are reference hi-fi headphones and uniquely feature Focal’s Beryllium driver technology. They are the result of 35 years of innovation, development and manufacturing of high-end speaker drivers and loudspeakers and effectively distill Focal’s Utopia speaker performance into a headphone.

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, this very high-end audiophile open-back circum-aural headphone for low-noise environments is 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.

Acoustic Transparency

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

Surround Sound

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.

Remarkable Comfort

Particular attention has been paid to the design of Utopia, in terms of use, comfort and overall aesthetics. These audiophile headphones feature elegant, high-quality materials, and comfort has been greatly enhanced thanks to the mechanical design which has been optimised to the smallest detail: the constant bend of the headband, an even distribution of weight, the design of the yoke and the memory foam ear-pieces.
