Neon 4, from FiR Audio

The Neon 4 is for the lover of smooth, creamy sounds, and it sacrifices no resolution to achieve it. It's equipped with (x3) BA drivers and a 10mm Dynamic for lows, all fed into FiR Audio's Kinetic Bass port. Neon 4 shines in its lush, upper mids and trebles, and a stellar sense of space and positioning from its ATOM XS module. Top it off with snappy, speedy bass, machined aluminum shell, and a sapphire glass faceplate, and you have an immersive, detail-oriented listening experience.

Kinetic Bass

Kinetic Bass is a bass you can feel. Traditional IEMs often lack depth and feel because they only provide you with half the sound. When you listen to music in a natural open-ear environment, you hear sound in two ways: air conduction and bone conduction. Air conduction is sound that you hear with your eardrums. Bone conduction is the conduction of sound through the bones in your head as it reaches the inner ear (cochlea). Hybrid conduction is when you can hear with both, air conduction and bone conduction, taking the IEM sound experience to a whole new level.

Kinetic Bass technology features a 10mm dynamic driver that is open and ported in an optimized manner directly facing the outside of the IEM shell. This allows low frequency sound to be transmitted directly to the ear cartilage and surrounding area. These low frequencies are converted to kinetic energy and reach the inner ear via bone conduction. This results in a more immersive sound with increased dimension and an off-the-charts low frequency extension.

ATOM Venting

No more pressure. Just easy listening, safer and longer. With a traditional in-ear, your ear canal is completely sealed. When the diaphragm is moving to create sound, it creates air pressure which has no way to escape, directly impacting your ear drum. This air pressure triggers your ear’s acoustic reflex which tightens the ear drum to protect the ear from loud sounds and causes listener fatigue. Triggering this emergency acoustic reflex can lead to hearing loss in the long term.

With the ATOM venting system, your ear drums can stay in their natural relaxed position, and you can listen to music longer and safer without your ears getting tired. The soundstage is wider and feels more natural like an open-ear listening experience but with all the benefits of in-ear monitors. All Frontier Series Universal-fit models come with the super ergonomic and easily swappable ATOM XS modules.

Open Acoustics

Open drivers with no sound tubes for freely flowing sound. Traditional in-ear monitors use a driver with a sound tube that carries the sound to the canal stem. The tube introduces unwanted resonances and results in a closed-in, stuffy sound. The FiR Audio Open Acoustics System consists of three major parts:

Open Drivers
The open drivers use no sound tubes and radiate sound directly into the Sound Reactor which allows the sound to freely flow to the ear canal. This results in a much larger soundstage and a more pure and natural listening experience.

Sound Reactor
The sound reactor is a chamber which shapes the sound that comes directly from the open drivers. The sound reactor uses natural acoustics to shape the sound instead of dampers and filters which are found in most traditional IEMs.

Sound Reflector
Our open high driver is located in the canal stem and features a sound reflector that directs the high frequencies into the ear canal. The results are remarkably smooth and airy highs with great extension.

RIGID Technologies

Rigid 2-Pin
The most durable 2-Pin connection on the market, rated for 1,000 connections without issue. Features revolutionary quadrant socket design and fits any 2-pin standard.

Rigid Snap Screen
An acoustically transparent mesh screen that protects debris from entering the canal stem and is easily replaceable.

Rigid 3D Printed Shell
The most comfortable and most durable CIEMs on the market. FiR uses a proprietary 3D scanning and 3D printing process that yields a fit so good you will forget you’re wearing IEMs. Shells are 20% thicker than the industry average which protects the external and internal components from getting damaged.

Kinetic Bass

Kinetic Bass is a bass you can feel. Traditional IEMs often lack depth and feel because they only provide you with half the sound. Kinetic Bass technology features a 10mm dynamic driver that is open and optimally ported directly facing the outside of the IEM shell. This allows low frequency sound to be transmitted directly to the ear cartilage and surrounding area. These low frequencies are converted to kinetic energy and reach the inner ear via bone conduction resulting in a more immersive sound.

ATOM Venting

No more pressure. With a traditional in-ear, your ear canal is completely sealed with created air pressure which has no way to escape, causing fatigue in your ear drum and potentially long-term hearing loss.

With the ATOM system, your ear drums stay in their natural position so you can listen to music longer and safer without tiring. The soundstage is wider and feels more natural.

Open Acoustics

Traditional in-ear monitors use a driver with a sound tube that carries the sound to the canal stem. The tube introduces unwanted resonances and results in a closed-in sound. The Open Acoustics System consists of 3 major parts:

Open Drivers
Uses no sound tubes and radiates sound directly into the Sound Reactor for freely flowing sound and a much larger soundstage.

Take a Journey to a World of Incredible Audio

Stunned – you’re left in awe and wonder. When you see the northern lights up close and personal, no other feeling comes close. They say, the journey counts so much more when you finally get to see the Aurora Borealis’ ribbons of light seemingly running and dancing endlessly up the dark, northern night sky.

FlipEars proudly say the same about their journey towards their latest flagship model – the FlipEars Aurora: A thing of awe; a thing of beauty. From the ground up, they've tried to outdo themselves, and here we are – caught in the wonder of these new in-ears.

The Aurora features FlipEars' twin 10mm dynamic SoniXwoofers, resulting in a tight bass response with deep extension. Mids are very transparent, purely reflecting details of any recording. Highs are truly crisp, but non-fatiguing – displaying dynamic flickers as wonderful as the polar lights.

Introducing Focal BATHYS

In order to meet the growing needs of the headphones market (wireless, portability, etc.), Focal has spent over three years working to adapt their knowledge to the world of “active” headphones, and to prove that they can equip them with high-fidelity sound.

Enter the brand-new Focal Bathys, the first set of wireless headphones with active noise cancelling and high-fidelity sound!

Bathys Dune: Step Into the Light

Focal has designed a luminous finish to join the Bathys collection, in contrast with the existing Black Silver finish and catering to its customers’ differing tastes. Applied to the headphones in their entirety, the carrying case and the cables, the Dune finish is inspired by quarry minerals, Greek landscapes and desert sands – in short, delicate spaces flooded with light. It combines a beige colour with silver details (grilles, rings, etc.) for an elegant, mellow and harmonious finish.

Cutting-Edge Technologies

Featuring the latest Bluetooth® 5.1 technology, a battery life of over 30 hours when using Bluetooth® and Active noise cancelling mode, Bathys headphones make the perfect travel companion to take with you wherever you go.

Compatible with SBC, AAC, Apt-X™ and Apt-X™ Adaptive codecs, they provide a broad choice of connectivity modes. For anyone looking for the best possible sound quality, the USB-DAC mode delivers a resolution of up to 24 bits / 192kHz for an uncompromising listening experience, thanks to the DAC and the integrated amplifier in the headphones!

Two modes of active noise cancellation are available: a Silent mode, optimized for trips with high background noise (planes, trains, etc.) and a Soft mode to aid concentration at home, in the office, etc. In addition, a Transparency mode enables you to stay connected to your surroundings.

Its fast-charging feature gives you 5 additional battery hours in 15 minutes of charging. A full charge only takes 1 hour and 30 minutes.

The Bathys design is inherited from Focal’s open- and closed-back headphones. The earcup grilles pick up Focal’s design code, with its highly aesthetic curves. Focal’s flame symbol features at the centre of the earcup, incorporating a white backlight system to be activated if desired, for an understated, chic effect. Another standout feature of Bathys is its elegant and timeless Black Silver color way.

Speaker Drivers Manufactured in France

In terms of sound, the Aluminum/Magnesium ‘M’-shaped dome speaker drivers – made in France in our ateliers – give the headphones an audio quality that’s unrivaled in its category. Our speaker drivers, equipped with patented Focal technology, have been slightly revamped to adapt to the constraints of a portable set of headphones – they are now lighter with a smaller volume. The result is a clear, dynamic and very precise sound, while retaining a sound signature that is optimized for use on the move: a present, ever-controlled bass.

Bathys Additional Features

A dedicated Focal & Naim application will enable access to an EQ that will adapt the sound to your musical preferences and other settings.

Bathys incorporates Google Assistant and Amazon Alexa voice assistants to stay connected at all times. It is also compatible with Google Fast Pair for a faster, more intuitive connection!

The headphones are supplied with a Jack cable and a USB-C® cable to serve frequent travelers who want to watch films on the plane. Their compact, rigid carrying case also means they can be taken anywhere!

From Focal

Following the launch of Stellia in 2019, global audio leader Focal presents Celestee. Delivering uncompromising audio quality, these headphones feature modern design and a blue finish, showcasing the French brand’s savoir-faire in audio. Focal has been present on the headphones market since 2012, developing a universally acclaimed collection of open-back and closed-back headphones.

A Brand New Navy Blue Color

Navy is the new Black! Dark blue is a versatile and timeless colour that has been increasing in popularity. By choosing Navy Blue, we are adding a sophisticated,
sumptuous feel to the headphones. The combination of this blue with copper and bronze accents is a trend influenced by interior and accessory design, and
has become popular in watchmaking and consumer electronics sectors. These shades offer a very interesting and elegant alternative to more traditional chrome and silver parts.

Focal focuses on combining sophisticated shades to create headphones with a highly original identity, unique in its market segment. The brand has chosen
Navy Blue after working with a Designer & Product Colourist. It is the first time this blue has made an appearance in the Focal collection, and it blends harmoniously with the Soft Copper finish.

Unique Focal Savoir-Faire

For over 40 years, Focal has been characterised by French innovation and manufacturing. The engineers have taken inspiration from their developments with
the Elegia headphones and introduced acoustic treatment inside the Celestee earcups. The sound is precise, balanced and boasts beautiful depth in
the bass. This exclusive technology is enhanced by the French savoir-faire of Focal: once the five manufacturing stages involved in the speaker
drivers are complete, they are tested and measured, and then kitted out by dedicated teams to provide uncompromising audio quality.

Fine Materials and Comfort

Celestee incorporates a combination of fine materials. Once again, attention is paid to every detail, including the accessories with the thermoformed woven carrying case in colours to match the headphones. The clean
lines of the aluminium yoke create controlled geometry to mould perfectly to the head while providing optimal grip. The choice of a semi-aniline leather and microfibre headband, as well as leather earpads, provides added
comfort while offering excellent soundproofing, whether you use Celestee at home or on the go.

Made in France, the new Clear Mg boast upgraded performance thanks to new magnesium dome drivers.

After more than three years of research and development, our engineers chose this new alloy which - combined with the dome’s ‘M’ shape - gives the headphones even greater lightness, rigidity and damping: the three success factors for any speaker/headphone driver.

The light and flexible surround also provides better dynamics and greater bass impact. The sound reproduction is even finer, with even greater precision and impact, creating a strikingly realistic sound.

The new grille has a honeycomb ‘M’-shaped design that more closely follows the curves of the driver. The more open design allows for a wider soundstage, while the reduced space between the driver and grille enables even more precise high-frequency reproduction.

Clear Mg headphones stand out first and foremost for their look. With their Chestnut and Mixed-Metal finish and their fine materials (leather, aluminium, microfibre), the headphones are extremely elegant. The new honeycomb grille on the earcups is a design highlight: not only does it increase the perceived value of the headphones; the more open structure contributes to the upgraded sonic performance. Finally, their perforated microfibre earpads offer enhanced opening and comfort.

Acoustics are also exceptional: the full-range drivers with ‘M’-shaped magnesium dome provide even more dynamic sound rendering, particularly in the low frequencies, and more detail across the full spectrum. Meanwhile, we have preserved the neutral sound signature that was so popular in the Clear.

A Brand New Version of Utopia Headphones

The winner of best headphones in the world several times over, Utopia has become a market leader in high-end headphones. In 2020, Focal introduced new packaging, including several accessories (two cables and a carrying case) to give our customers an improved unboxing experience. Today, we are proud to introduce the new 2022 Utopia: an evolution in acoustics, design, and aesthetics.

The Best of High-Fidelity Sound

Utopia still harbors its ‘M’-shaped dome, pure Beryllium speaker drivers for transparent and true sound reproduction. However, Focal has developed a brand-new voice coil that brings together reliability and lightness to the speaker driver.

Some customers have unfortunately encountered issues with speaker drivers in their original Utopia headphones, so Focal has worked tirelessly to resolve this. The new voice coil is made of 30% copper and 70% aluminum making the driver extremely reliable whilst maintaining excellent performance.

Pushing the limits even further, Focal improved linearity and reproduction of the treble by incorporating the ‘M’-shaped speaker driver grille (developed for Clear Mg), following the curve of the dome. With the new Utopia, you get unequalled sound performance with vastly improved reliability!

A Distinguished Design

Combining comfort and aesthetics, the design and concept behind Utopia certainly live up to these exceptional headphones. The forged carbon yokes, made from recycled carbon, are modern and sophisticated in style, whilst providing more lightness. The honeycomb grille, synonymous with Focal's open-back headphones, and the Black Chrome ring showcase subtle design details, like the Yin & Yang on the outer case and the black and red double grille on the speaker driver.

So many aesthetic features that fiercely embody Utopia: the perfect balance between technology and design!

With the new Utopia headphones, we are delighted to introduce new design codes, which will also be used on Focal's future Utopia products.

Utopia are the Ultimate Focal Headphones

Their full-range, Beryllium, ‘M’-shaped speaker drivers are fully open-back and run with no passive or active correction, from 5Hz to over 50kHz! The listening experience they deliver is strikingly real, precise, and dynamic, with a soundstage that is both wide and deep: close your eyes and feel the musicians beside you. Combining comfort and aesthetics, Utopia delivers uncompromising design and conception. The forged, recycled carbon yokes are modern and sophisticated in style, whilst providing more lightness. The honeycomb grille and Black Chrome ring showcase subtle design details, like the Yin & Yang on the outer case, the black and red double grille on the speaker driver, and more.

Artisan Crafted Open-Back Sound

The Fostex TH616 Limited Edition open-back headphone commemorates the 50th anniversary of the birth of Fostex. Carved from high-quality solid black walnut wood in a design reminiscent of traditional Japanese woodwork, the headphone has been crafted into an open housing while achieving reliable acoustic performance. Enjoy a new premium-feeling headphone that combines "Japanese" taste with an excellent acoustic structure, carefully assembled one by one.

Detailed Features

Open housing carved from solid black walnut. The housing is carved from solid black walnut, a high-quality wood, and has an opening with a design inspired by the fantastic natural phenomenon of sunlight shining through gaps in the trees. This machined design not only reduces weight and maintains rigidity, but also avoids uniformity on the housing surface, suppressing the generation of mode vibrations and reducing unnecessary resonance. In addition, in order to eliminate the effect on the sound caused by the resonance of the openings, all the openings vary in layout to suppress the occurrence of resonance at specific frequencies.

Biodyna diaphragm uses ultra-fine bio-cellulose fiber material. Utilizing know-how accumulated over many years, Fostex blended bio-cellulose and other fibers under optimal conditions. Achieves low specific gravity, high Young's modulus, and high internal loss. In addition to delicate, high-resolution, beautiful mid- and high-frequency reproduction, the adoption of free edges with good linearity faithfully reproduces large-amplitude low-mid frequencies.

Super strong magnetic circuit. The magnetic circuit is equipped with a 50mm driver unit with a magnetic flux density of 1 Tesla. The ultra-strong magnetic circuit provides a wide dynamic range with low distortion.

High quality and lightweight mechanical parts. Aluminum is used extensively for mechanical parts, achieving a high quality feel and light weight. By using high-density resin for the baffle plate, a reduction in the generation of resonance sound has been achieved for high resolution, rich midrange, and high-quality bass reproduction.

Detachable connector port. The cable side terminals and the detachable contact terminals on the headphone body side are rhodium plated for high hardness, wear resistance, and corrosion resistance, improving reliability. In addition, it is also possible to support balanced connections with the optional replacement balanced cable ET-H3.0N7BL.

High-performance pure copper headphone cable. A high-performance pure copper HiFC high-grade cable that exhibits excellent conductivity through special processing is used to clearly express all bands.
