Focal, the French loudspeaker manufacturer renowned for its exclusive speaker driver technology, is unveiling three new models of headphones. They bring major innovation in acoustic components and mechanical design. Initiated four years ago, this huge project has now given life to Listen, Elear and Utopia.
Embodying Focal’s core values, these products combine exclusive technology, remarkable audio performance and the brand’s own design codes. This month also sees the inauguration of Focal’s new production line at its site in Saint-Etienne, France which will be entirely dedicated to manufacturing Elear and Utopia headphones.
Utopia & Elear
Experience the sound of the high-fidelity loudspeakers in headphones
Utopia and Elear headphones are the result of a rather risky challenge: to offer an audio experience worthy of the brand’s high-fidelity loudspeakers through two new products. In order to achieve this, Focal approached the design of the various components in these headphones very differently to other players in the market. Focal’s desire was to bring the sound and feeling of listening to its high-end Utopia loudspeakers to headphones.

The first obvious aspect is the extent of the open design of these two products. When Utopia or Elear are being worn, the sensation is remarkable: there is no change in perception in terms of room size. This desire to not have an impact on the feeling of the room the user is in, clearly contributes to the realistic sound of these two headphones.
The next step for Focal’s mechanical engineers and designers was to improve the comfort of the headphones. There are still many high-end headphones which no doubt offer excellent performance, but comfort is a difficult issue over long periods. So, Focal focused on designing a headband with a constant bend, regardless of the size of the user’s head size. This spreads the weight of the headphones evenly over the head to avoid the feeling of pressure on the head or ears, which is all too often the case with other products.
The yoke developed for these two projects is also very impressive, both in terms of purity of the design and in terms of comfort. The yoke doesn’t have traditional vertically rotating mechanics, as this has been integrated into the headband.
In addition to this, the asymmetry of the attachment points connecting the yoke to the ear-piece improves the distribution of clamping pressure and ensures excellent sealing and great comfort.
The ear-piece also deserves praise for its remarkable aesthetics and its impressive open design. This avoids any mechanical compression of the transducers while preserving exceptionally realistic sound. Equipped with high-density memory foam, the headphones provide perfect sealing and adapt seamlessly to heads of all shapes and sizes.
By refusing to accept the compromise of having ports, which would of course allow for numerous tuning possibilities, particularly in the low end, Focal’s priority was to get rid of the distortion typically experienced with this type of open design. The only limit with this concept is the necessity to conceive the headphones from the start around a loudspeaker with a perfect frequency response. The only possibility for sound tuning would come down to the choice of materials and their properties, for example the magnet, the voice coil, the surround or, of course, the dome. There was just one watchword: to have the lightest moving assembly possible in order to be able to reproduce the highest frequencies.
A characteristic which really sets Focal apart is its ability to innovate and push back the limits in the field of speaker drivers, while managing its own industrial process at the production site based in Saint-Etienne, France.
The only means of succeeding with these acoustic challenges was to perfectly master the development and production processes. For this reason, a whole new production line was developed at the Saint-Etienne site for manufacturing Utopia and Elear.
Utopia — The Purity of sound at its apogee
Utopia is Focal’s flagship product. The sound quality is striking in terms of realism, neutrality, dynamics and clarity. The user will forget the headphones are even there, and the reproduction of the audio signal is of unrivalled clarity. The Beryllium “M” dome delivers music and speech with an ease and naturalness unheard previously from headphones. Particular attention has also been paid to the design in terms of types of use, comfort and overall aesthetics. The shifting of the articulation to the inside of the headband is the perfect example of this, and gives the carbon fibre yoke a perfectly smooth and seamless design. The lambskin leather sourced in New Zealand, chosen after many alternative samples were examined, tested and even auditioned, used for the ear cushions and headband emphasises the sleek design, the high performance and the comfort of Utopia, and creates a sense of elegance. Supplied with a 4m OFC cable, including a Neutrik® 6.35mm (1/4“) stereo plug and two shielded Lemo® connectors with self-locking bayonet system.

Elear — The high-fidelity experience
Elear are the brand’s audiophile headphones. In essence, they are the same as Utopia headphones when it comes to the loudspeaker design and the mechanics. The solid aluminium yoke gives these headphones a remarkably smooth seamless design. The microfibre ear cushions provide the user with maximum comfort, an essential quality for long sessions. The key difference being an Aluminium/Magnesium alloy dome. Supplied with a 4m OFC cable, a 6.35mm (1/4“) stereo Jack and two 3.5mm (0.14“) Jacks with self-locking system

Pure innovation The new ‘M’-shaped dome — tending towards a plane wave with an ultra-nearfield loudspeaker
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 the famous pure Beryllium dome in order to offer an unrivalled mass:rigidity:damping ratio. Elear, on the other hand, has a dome made of an aluminium/ magnesium alloy just like Aria speakers.
Surround — tending towards invisibility
The mass target must also take into account the surround. After trying several raw materials such as PE, mylar, fabric, silicone, the only one able to reach both compliance and mass targets was NBR. This material combines by essence softness, lightness and mechanical functioning linearity. At the end of the development process, the result was a world premier: a surround almost three times thinner than the competition.
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 a high potential Xmax, to ensure they are as linear and dynamic as possible.
A new monolayer voice coil — A monolayer voice coil without former
As part of the project, Focal designed the very first voice coil without former (patent pending) 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 high- end 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 of the moving part.
The sum of the parts
This challenge required months of work to partner very low mass, maximum excursion and the linearity of the moving assembly, all while ensuring perfectly balanced sound, regardless of the volume.
Listen — Premium mobile headphones with Focal sound
Listen are premium mobile headphones and like all of Focal’s other headphones, they are designed in France and combine all the advantages of premium mobile headphones, for intense listening sessions. They provide excellent noise isolation with large ear cushions that ensure Listen headphones preserve all their acoustic qualities, even in loud environments. The heat-sensitive, very high density memory foam offers impressive comfort for the listener. Listen also benefits from all the research that went into designing Utopia and Elear headphones with the aim of keeping the shape of the headband constant, regardless of the size of the user’s head. This has resulted in remarkable comfort, even during long listening sessions.
When designing Listen, particular attention went into ensuring their ability to withstand the great physical demands one has of portable headphones. What’s more, the compactness of the headphones when folded away makes them an ideal travel companion.

Listen are supplied with a flexible carrying case and an aircraft adapter. A 1.4m cable is also provided with a 3.5mm jack and a bayonet connector locking device, where a quarter-turn holds the cable in place to ensure it stays connected to the headphones, however demanding the environment. The in-line omnidirectional microphone offers excellent sound pickup, even in loud surroundings. Finally, the large remote control with just one button (compatible with all smartphones) makes it extremely simple and quick to manage calls and control your music.
In terms of speaker drivers, Focal showcases its 35 years of expertise. At the source of Listen’s acoustic quality is the innovative 40mm driver. A Mylar cone has been used on the entire driver, and the dome has been given a titanium coating.
This ensures optimal suspension compliance and gives the dome a lot more rigidity. Thus, Listen also has an excellent dynamic range, tight bass and remarkable tonal balance.
