In ear headphones with five dynamic drivers Groundbreaking innovation Five custom dynamic drivers Precise electronic crossover High-purity silver-plated copper cable Groundbreaking innovation Earphones with multiple drivers are not uncommon, but most are based on balanced armature drivers, which are less technically sophisticated. 7Hz is breaking new ground by introducing the FIVE, the industry's first earphones with five dynamic drivers per side, setting a new standard in audio technology. Five customised dynamic drivers The 7Hz FIVE is equipped with five customised 6 mm dynamic drivers per side. Each driver operates independently in its own acoustic chamber so that each driver contributes to the overall sound. This design provides unrivalled clarity and separation, creating a rich and engaging listening experience. Precise electronic crossover and premium components The FIVE utilises a carefully engineered electronic crossover consisting of high-precision imported electronic components. This combination ensures seamless integration of low, mid and high frequencies for a uniquely refined listening experience. High-purity, silver-plated, oxygen-free copper cable The earphones are supplied with a high-purity, silver-plated, oxygen-free copper cable. This cable has a four-core, parallel design with 49 wires per core, totalling 196 wires. This improves signal transmission and reduces interference, resulting in pure, unadulterated sound. Inspiring sound quality The 7Hz FIVE delivers solid, thunderous low frequencies, robust mids and smooth, non-fatiguing high frequencies. With their high energy and fast dynamics, these earphones offer a sound experience similar to that of high-quality speakers, enveloping users in rich, detailed sound. What`s in the box In ear headphones High-purity, silver-plated connection cable Transport case 6 pairs of silicone tips

14 BA driver in-ear headphones High-precision 3D-printed acoustic tube structure Ultra-thin acoustic tube structures O.15mm RLC network Frequency division correction technology High-damping air pressure equalisation system Lossless high-frequency vibration suppression technology Ultra-low frequency enhance acoustic module High-precision 3D-printed acoustic tube structure The first technology is the acoustic crossover. It utilises physical frequency division to adjust the frequency response of the individual drivers. It has been finely tuned and optimised to harmonise the sound waves of the different tubes. This eliminates the peaks caused by the resonance of the device with conventional frequency division technology. Non-Destructive Direct Drive Topology Technology The Non-Destructive Direct Drive Topology technology in AFUL Cantor earphones improves the clarity of sound by eliminating resonance through an asymmetrical sound path to deliver extended, smooth highs. This advanced approach outperforms conventional attenuation methods and preserves the detail of high frequencies without drowning them out. Multi-dimensional Frequency Division Architecture Technology The AFUL Cantor's multi-dimensional frequency division architecture integrates 14 BA drivers, each with a specific function, to deliver a cohesive sound image with smooth frequency transitions and a comprehensive, balanced sound experience. High-precision 3D-printed acoustic tube The Cantor earphones utilise high-precision 3D printing technology to create acoustic components with ultra-fine paths of just 0.15mm, pushing the boundaries of 3D printing. This precision improves audio performance and delivers bass with unrivalled depth and clarity. RLC network frequency division correction technology It can act directly on the frequency response of the pair, helping to overcome peaks caused by the resonance of the unit with conventional frequency division technology. It also gives the balanced armature drivers a smooth high frequency response that rivals that of an EST unit. High-damping air pressure equalisation system The third technology is Air Pressure Relief. It equalises the air pressure in the ear canal. This reduces the fatigue and discomfort that can occur after prolonged listening. The air pressure equalisation technology also improves the texture, depth and elasticity of low frequencies. Acoustic module for ultra-low frequency enhancement Two composite driver units are used. One unit extracts an ultra-low frequency range of 10-100 Hz through an ultra-thin and ultra-long sound tube, the other is used as a bass unit. The overall low-frequency characteristics have changed fundamentally, the elasticity has been greatly improved, and the bass depth has reached an excellent level. Lossless high-frequency vibration suppression technology The AFUL Cantor uses a specially developed acoustic structure to install high-frequency units that can reduce structural resonance peaks. It has been developed using a special mould design, sound channels and precise calculations to further reduce resonance. The high-frequency attenuator achieves a smooth high-frequency response, the extremely high frequency extension is not attenuated, and the overall quality of the treble reaches the level of electrostatic headphones.

Hybrid in-ear headphones 2DD+4BA+1Micro Planar High-precision 3D-printed acoustic tube structure LC network frequency division correction technology Highly damped air pressure equalisation system 8-core, high-purity copper cable with 144 cores and silver coating Wide frequency range A wide frequency range enables more accurate and realistic reproduction of instruments by effectively capturing both the primary fundamental frequencies and harmonic overtones. Many earphones on the market can only handle the main frequency ranges and fail to reproduce harmonics due to their limited frequency range. Easy to drive Thanks to its advanced technology, the Performer 5+2 is highly efficient and easy to drive. While a high-quality source maximises its potential, it also offers excellent sound quality when used with portable dongles or Bluetooth DAC/amplifiers. Exceptional bass and treble The addition of two dynamic drivers and a microplanar unit, as well as AFUL's unique acoustic and circuit design, ensure that the bass structure, depth, treble resolution and instrument separation are first class. Technology High-precision 3D printed tube structure LC network frequency division correction technology High damping air pressure equalisation system By integrating precise and complex 3D acoustic structures with RLC network crossovers, AFUL has significantly enhanced acoustic performance. This advanced modelling and design of the ‘acoustic structure-speaker-RLC network’ combination has enabled a significant leap in sound quality. Exceptional low- and high-frequency acoustic performance Low frequencies have been enhanced by two dynamic drivers and a 3D-printed Y-shaped structure, significantly increasing bass elasticity and density. The addition of a microplanar driver for the high frequencies significantly improves the extension of the treble and increases the overall sound accuracy. The acoustic structure and crossover have been further refined, improving the overall sound coherence and texture.

Flagship in-ear headphones 2 dynamic 6 BA 8 drivers IEM's push-pull dual dynamic driver units Custom Knowles enhanced mid-BA drivers Titanium+7000 aluminium construction Semi-open design Mid-frequency notch filter Four-way acoustic design Patented S.Turbo design, improved bass extension, more robust bass 3 interchangeable audio filters enabling different listening experiences High-purity monocrystalline sterling silver cable, 8 strands with a total of 224 wires Co-developed with Tokyo Onkyo Ltd. Rubycon film capacitor crossovers in audiophile quality Physical pass-through, refined frequency division Optimised wearing ergonomics Interchangeable 3.5/4.4 mm plugs Flagship sound Three years ago, the FH9 was launched, the first high-end hybrid headphones from FIIO. With its energetic dynamics, wide soundstage and pleasant sound quality, it was enthusiastically received by hi-fi users worldwide. It gradually became known among audiophiles as a great example of ‘balanced headphones’ and far exceeded expectations in terms of popularity. It is still a competitive headphone on the market today. The new FIIO FH19 from FIIO is a significant upgrade that incorporates a lot of user feedback. It retains the distinctive sound and premium build quality of the FH9 and has also been developed in partnership with Tokyo Onkyo Ltd. in Japan and Knowles in the USA. It features a truly high-end acoustic design, with richer and fuller mids and a more robust yet flexible bass. In addition, the fit has been redesigned and optimised based on the characteristics of the human ear, so you can enjoy flagship-level comfort. The top, further improved The new FIIO FH19 is equipped with two 13.7mm dynamic drivers and six balanced armature drivers, matching the flagship. The bass is reproduced by a completely new push-pull dual dynamic driver unit, which was developed jointly with Tokyo Onkyo Ltd. in Japan. This driver is characterised by significantly improved extension, cohesion and speed in the low frequency range. The mid to high frequencies are handled by specially adapted, improved Knowles Balanced Armature drivers for the midrange, achieving greater sound energy density for rich and delicate vocals that are wonderfully musical without sacrificing detail. As the cones move back and forth, the overall direction of movement of the two dynamic drivers remains consistent due to the push-pull arrangement, ensuring phase consistency. This effectively doubles the driving force and allows the diaphragms to damp each other with air. As a result, the dynamic drivers exhibit more stable movement and completely suppress any residual sound after the end of the audio signal. Compared to typical dynamic drivers, push-pull dual dynamic drivers require only half the amplitude to reach the target sound pressure level. This results in lower cone excursion, which significantly improves linear drive performance and further reduces intermodulation distortion, allowing the driver unit to deliver a cleaner sound. Customised Knowles Enhanced Mid-BA Drivers The FIIO FH19 uses six Knowles Balanced-Armature drivers as mid and high frequency units. To achieve an even higher level of vocal sound quality, FIIO has worked with Knowles to develop a custom balanced armature driver with enhanced midrange. By adding acoustic vents in the rear cavity of the driver, the mid-frequency driver gains more sound energy compared to typical mid-frequency drivers. This brings out the benefits of the midrange driver even more, resulting in rich and smooth vocals that sound as immersive and realistic as if the singer were standing right next to you. 7000 Series titanium and aluminium construction The FIIO FH19 boasts a build quality worthy of a flagship speaker, helped by its titanium centre frame. Its luxurious feel and uniquely charming titanium colour give it a premium look. As the part of the headphones that is touched the most, the rigidity and corrosion resistance of the pure titanium metal bracket thoroughly protects the rest of the headphone housing and makes it resistant to everyday wear and tear. The FIIO FH19 uses 7000 series aluminium*, which ensures a robust and resistant housing while reducing the weight of the headphones. Thanks to this aluminium, the FH19 offers a comfortable wearing experience even with more drivers and a more complex acoustic design. *7000 series aluminium alloy is widely used for aircraft fuselages, wings and other important components. It has high strength, rigidity and corrosion resistance. Fatigue-free listening, large sound stage Semi-open design The semi-open design was highly praised in the FIIO FH9, FH7S, FH5S and FD5. In the FH19, this proven semi-open design is used again and has been specially adapted to combine with FIIO's balanced pressure relief technology for the front and rear cavities - the result is a more natural and relaxed sound with a wide sound stage. This design efficiently equalises internal air pressure, eliminating the feeling of pressure on the eardrum, which also helps protect your hearing. Enjoy long listening without fatigue. Mid-frequency cut-off filter The FH19 features a variety of different drivers and acoustic design principles. The scientific tuning of the individual parts so that they form a harmonious whole is the essence of high-level tuning. To achieve this, the FIIO development team has developed a special ‘mid-frequency cut filter’ for the FH19 hybrid earphones. Further enhanced mid-range tests have shown that the FH19's mid-frequency cut filter not only retains the high resolution and clarity of the BA drivers, but also increases the sound pressure level in the mid-frequency range. This makes the vocals denser and fuller while ensuring a smooth transition between the dynamic driver and the BA driver for the mid frequencies. The FH19's mid-frequency cut-off filter effectively filters out the high-frequency 8 kHz peaks generated by the mid-range drivers. This reduces the overlap between the sound produced by the midrange and tweeter drivers, eliminating sibilance while ensuring high sound quality. The mid-frequency cut-off filter can also advance the crossover point of the balanced armature units. This ensures that these drivers have a truly independent frequency range and there is no interference with the other drivers, allowing the tweeters to perform to their full potential. The working principle of the FH19's mid-frequency cut-off filter: When the frequency of the sound wave is close to the natural frequency of the resonance chamber, the inner wall of the resonance chamber and the air generate vibrational friction, which converts the sound energy of certain frequency bands into mechanical and thermal energy, thereby consuming sound energy and achieving a sound absorption effect. Conversely, the resonance effect in the cavity is weaker if the frequency of the sound wave is far away from the natural frequency of the resonance chamber, resulting in less sound absorption. This principle forms the basis for the operation of the FH19's mid-frequency cut-off filter, which adjusts the sound produced by the mid-range drivers and achieves a physical pass-through effect. Focusing on small details to achieve big improvements Suspended voice coil To achieve flagship-level driver performance, the FIIO FH19 utilises a suspended voice coil. With this design, the voice coil leads are routed directly from the centre hole underneath the cone, allowing them to float in the gap. This avoids unnecessary contact and prevents additional adhesive load. Compared to conventional diaphragms*, the floating voice coil design ensures smooth and gentle diaphragm movement, minimising interference from other factors and fully exploiting the diaphragm's inherent potential. *Conventional diaphragms often use special adhesives to bond the voice coil to the diaphragm surface. However, this approach not only increases the overall weight of the diaphragm, but can also lead to a dynamic imbalance during dynamic movements of the driver. Uneven local weight distribution can lead to vibration irregularities, change the compliance of the cone and even cause distortion due to voice coil scraping. This ultimately affects the overall performance of the driver. Scalpel-like accuracy Rubycon audiophile-grade film capacitor crossovers The FH19 is equipped with the same high-precision Japanese film capacitors as the FA19, which offer exceptional accuracy in phase matching and have been developed with the utmost care for sound quality. While conventional resistor-based crossover components typically have an accuracy error of around 1%, the FH19 achieves an impressively low error rate of 0.1%. In addition, the FH19 not only achieves more precise crossover points compared to conventional ceramic capacitors, but also effectively improves the resolution in the high frequency range and results in a more detailed sound overall. Acoustic four-way design "While the basic design is derived from the FH9, the FH19 builds on and surpasses its predecessor by updating the bass and midrange drivers and implementing them in a more precisely controlled four-way crossover design. Special push-pull dual dynamic driver units are used in the low frequency range, and a ‘Turbine Low-Frequency Boost Technology’ is used for physical low-pass filtering for relaxed yet natural bass. For the mid frequencies, the FH19 introduces an innovative ‘3+1 semi-open’ acoustic layout with balanced armatures. This is complemented by a newly designed resonance chamber that allows for two separately managed mid-range areas, resulting in richer and more emotional mids. For the high frequencies, the FH19 retains the coaxial design with an acoustic guide, but also incorporates audiophile-quality Rubycon film capacitors. This combination enables high resolution with excellent high frequency response." Chief Engineer of FIIO IEM's R&D Centre Turbo-charged energy Patented S.Turbo design Inspired by turbochargers in super sports cars, the FIIO development team has created the patented S.Turbo acoustic design. This design ingeniously utilises the properties of sound wave guidance and improves bass performance through a turbine-shaped structure. The result is a deep and lively bass. In addition, the design skilfully filters out excess mid to high frequencies from the dynamic driver, ensuring smooth transitions between the low and mid to high frequencies. The result is a powerful and robust sound. Patent number: ZL2018211416279 Interchangeable audio filters As befits an IEM flagship, the FH19 has three pairs of interchangeable audio filters. Each filter has a different internal attenuation and mesh density, so you can customise the sound to your preference: Red audio filter - Boosts low frequencies and provides powerful and impressive bass Black audio filter - Provides a balanced sound that is clear and transparent Green audio filter - Delivers fine and detailed highs *Green filter is pre-installed. The other filters are included in the carrying case. Top-class comfort Optimised wearing ergonomics 10° ear cup angle Based on user feedback and numerous optimisations, the angle between the ear cup and the wearing surface along the Y-axis is exactly 10°, while the length of the ear cup remains unchanged. This adjustment means that the earphones fit even more precisely in the ear canal, which significantly improves both wearing comfort and stability. Gap-free, comfortable fit, the FH19 has a completely new, more three-dimensional rear recess design. Numerous tests led to numerous ergonomic optimisations, such as ear-friendly protrusions with a thickness of approx. 1.4 mm, which ensure a firm and stable fit by minimising any unwanted movement. The brand new design of the FH19 back panel features a slight reduction in thickness - approximately 1 mm - in the area corresponding to the fold of the human ear. This structural design significantly reduces the feeling of pressure and compression on the ear from the earphones. In combination with the excellent housing materials, the FH19 disappears into your ears while delivering a first-class sound. Pure silver for pure sound The FH19 comes with a high-purity pure silver cable as standard. Each of the 8 strands consists of 28 wires, totalling 224 wires. Each individual wire is insulated with enamel and the cable is braided into strands. The outer jacket is made of imported, transparent and environmentally friendly TPU, which enhances the transparent appearance of the cable. In addition, this material effectively prevents the cable from yellowing with prolonged use and becoming stiff at low temperatures. *The cable is identical to the LC-RD Pro 2022 Straight, interchangeable twist-lock audio plugs Supports 3.5/4.4 mm plugs and features extended stainless steel MMCX plugs *Patent for interchangeable audio plugs licensed by FABRILOUS. Listen the way you want 22 pairs of ear tips included As befits a flagship model, the FH19 comes with 22 pairs of ear tips in different shapes and sizes* to give you a comfortable listening experience no matter what your preferences are. In addition to the popular HS18 and SpinFit ear tips, the new HS18 silicone ear tips are also included. Specifications Headphone type: Hybrid in-ear monitors with dynamic and BA fittings Frequency response: 8Hz-40kHz Impedance: 16Ω@1kHz Sensitivity: 109dB/mW@1kHz Cable type: 8 strands with a total of 224 wires of high-purity pure silver Length of cable: Approximately 1.2m Weight of headphone unit: Approximately 12g (without cable) Earphone connection: Extended MMCX Audio plug: Straight twist-lock plug3 pairs of HS20 silicone ear tips (S/M/L) 3 pairs of HS18 ear tips (S/M/L) 3 pairs of SpinFit ear tips (S/M/L) 2 pairs of foam ear tips (M) 3 pairs of bass ear tips (S/M/L) 3 pairs of balanced ear tips (S/M/L) (size M pre-installed) 3 pairs of vocal ear tips (S/M/L) 2 pairs of dual flange ear tips (M) 1x HB7 carrying case 1x cleaning brush 1x MMCX quick release 1x magnetic cable clip 1 set of audio filters red/black/green 1x pure silver earphone cable with interchangeable plug 3. 5/4.4 mm 1x quick start guide

The smooth grain of the wood, which is unique to each piece, and the fine texture bring out its natural beauty. This very dense solid wood also helps to effectively reduce cavity resonances and minimise standing waves. 60 mm dynamic driver The FIIO FT1 features a newly developed 60 mm second-generation dynamic driver specifically designed for FIIO's first closed-back over-ear headphones. The larger-than-average driver improves the efficiency of energy conversion and provides a solid foundation for powerful bass. In addition, the larger size of the driver results in lower resonance points at low frequencies, allowing for deeper bass, dynamic sound and an overall authoritative sound. Nanofibre composite cone - paper making technology and the art of sound The cone of the FIIO FT1 is mainly made of carefully selected paper wood fibres based on 90 year old spruce wood from Northern Europe. European spruce is a premium raw material for musical instruments and fibre products, known for its clear and natural sound. Mature northern European spruce wood undergoes a series of processes including soaking, boiling and beating to produce a specific pulp. A certain amount of carbon fibre material is added to meet the acoustic resilience requirements. The membrane is then baked and moulded in a further round so that it finally reaches a thickness of around 0.1 mm, is light and resistant. To bring out the full acoustic performance of the nano wood fibres, a lightweight PU material with high internal resistance is used for the suspension seal, which improves the compliance of the diaphragm and increases elasticity in the low frequency range, enhancing the density of voices from the sound source, resulting in warm, rich voices. In keeping with its overall acoustic concept and high-quality listening experience, the FIIO FT1 uses a nano wood fibre cone. This membrane consists of carefully selected paper fibres in combination with a lightweight PU (polyurethane) suspension seal. It is characterised by excellent high-frequency extension and excellent transient response, resulting in a clean, precise sound with clear imaging and giving you the unique sweet, rich and dense midrange sound of paper cones. This driver works in harmony with the FT1's other acoustic design elements to deliver a specially tuned frequency response for a pure and pleasing sound experience. It's as if the elegant aesthetics of the ‘paper’ driver translate perfectly into beautiful sound. Cutting-edge technology and innovative applications The FIIO FT1, FIIO's first closed-back over-ear headphones, pioneers a new generation of in-house acoustic technology - the W-shaped suspension seal. The 25 mm diameter voice coil is larger compared to similar models and has been specially optimised and tuned. Compared to typical, similarly sized cones, the W-shaped cone achieves a 25.8 % larger effective vibrating area, allowing it to store more energy reserves. The FT1's cone with a hard dome and a compliant suspension seal allows the 25 mm voice coil to drive the stiffer dome region directly. This design minimises vibration losses between the different materials and reduces distortion caused by driver break-up, allowing the FT1 to deliver a more refined sound. Ultra-fine Japanese CCAW voice coil To ensure a robust and high-quality sound, the FIIO FT1 uses a specially imported Japanese ultra-fine CCAW (Copper-Clad Aluminium Wire) voice coil with a diameter of up to 25 mm. A longer copper wire of the voice coil can directly improve the efficiency of the transducer and the drive capacity, resulting in a better transient response and a purer, more pleasant sound. Each individual wire core in the CCAW coil has a diameter of approx. 0.035 mm and is therefore as thin as a hair. In addition, the voice coil frame of the FT1 is made of lightweight KSV (Kapton), which also contributes to a significant reduction in overall cone mass. The result is improved response speed and minimised reverberation. Closed-back design The FT1 is FIIO's first closed-back over-ear headphones and incorporates a number of features specifically designed to enhance the closed-back listening experience. A series of sound-absorbing components in the FT1 effectively reduce ambient noise, including external voices and ambient noise, by up to 26 dB. Whether you're commuting, editing recordings, working in the office or gaming, the FT1 lets you immerse yourself in a high-fidelity audio world. It is a truly great sounding all-rounder headphone. U-shaped sound attenuation tube for improved noise reduction The U-shaped sound attenuation tube specially developed for the FIIO FT1 not only improves passive noise reduction, but also ensures that sound energy is channelled through the flute over a certain length and angle, increasing the air viscosity and reducing the resonance frequency of the cavity. This further improves the bass expansion. You will clearly feel the air movement and the focussed power of percussion and strings. Conical baffle The pursuit of excellent sound has always been the essence of hi-fi. Based on the characteristics of the FT1 dynamic drivers, the development team has designed a conical baffle for them. This device allows the entire driver to be positioned parallel to the human ear, breaking sound convergence and avoiding standing waves. The result is minimal attenuation of high frequencies for true hi-fi sound quality. 32-Ω design with high sensitivity The FIIO FT1 is designed to provide users with a high-quality hi-fi experience in various usage scenarios. To achieve this, the FT1 has a low impedance of 32Ω and offers an acoustic sensitivity of 113dB/Vrms@1kHz (equivalent to 98dB/mW@1kHz). This significantly reduces the need for drive power, allowing you to enjoy outstanding sound quality effortlessly. Adaptive 3-axis headband The FT1 has inherited the excellent ergonomic design of the FIIO FT series. The adaptive 3-axis headband allows free rotation at different angles. This design adapts to different head sizes and ensures a snug fit on the head for improved comfort and minimised sound loss. 10Hz-40kHz ultra-wide frequency response The FIIO FT1 has a frequency response of 10 Hz to 40 kHz, providing a studio-like listening experience. Every little detail is reproduced cleanly, just as you would expect from a professional audio device. Lightweight, portable headband To make the FT1 headband more portable and lighter, it is equipped with high-quality steel rails that significantly increase the durability of the headband. You will feel the precision and sophistication of the mechanical construction every time you adjust the headband. In addition, compared to similar products, the FT1 offers an extended adjustment range from 0 to 11 clicks to adapt to different head sizes. The part of the headband that comes into contact with the head is made of lychee leather for a soft and comfortable feel. Breathable fabric ear pads Experience comfortable long listening sessions and say goodbye to congestion. The FT1 is equipped with breathable fabric ear pads, which are made of a textile material that comes into contact with your skin. The high-density, breathable mesh design efficiently dissipates the heat that builds up between the ear pads and your ears. The side of the ear pads is made of protein leather, which not only looks good, but feels good too. Dual TRS headphone jacks The FIIO FT1 features two 3.5mm TRS headphone jacks, allowing you to easily switch and upgrade to a different headphone cable. Includes high-quality headphone storage bag The FT1 comes with a high-quality headphone storage bag, made with the same materials and techniques used by top French brands. It offers a refined and elegant look rarely found in this class, but undoubtedly useful for protection. 2 silver-plated oxygen-free copper cables included The brand new FT1 comes with two headphone cables - with 3.5 mm plugs (single-ended) and 4.4 mm plugs (balanced). Both cables are identical and consist of an oxygen-free, copper-coated silver wire base with 392 wires, have a thickness of 24AWG and are 1.5 metres long. This makes the FT1 compatible with many audio devices as you can easily switch between cables.

With a powerful, high-quality amplifier you can tap into the vast sound potential of the FT3 350Ω version – experience its fully extended treble and bass, vast soundstage, and ultimately relaxing yet powerful soun Art of harnessing energy for great sound - 60mm large dynamic driverSound comes from the vibration of material – thus, the choice of the driver is quite important in determining sound quality. The FT3 features a large 60mm dynamic driver, uncommon in its class. Compared to a smaller driver, the FT3 can push more air and convert energy into the sound more efficiently – resulting in a more natural yet robust sound with an expansive soundstage.The FT3’s large dynamic driver also has other benefits. For example, due to its large size, the diaphragm is capable of bearing higher output power, leading to less distortion under large dynamic signals. Also, the larger driver is more easily able to produce lower frequencies for deeper reaching bass. Thoughtfully designed - Beryllium-plated gasket + DLC diaphragmThe diaphragm is one of the most important parts of a dynamic driver. And not just any diaphragm material can meet the demands of the FT3 due to the large driver size. After countless testing at FiiO, a beryllium-plated gasket + DLC diaphragm was chosen.The FT3 driver gasket is plated with beryllium. This not only results in a lighter gasket (and thus a lighter driver), but also a more rigid gasket better able to handle the movement of the large dynamic driver for less distortion. The diaphragm of the FT3 is made of DLC (Diamond-Like Carbon),  – which is both highly sturdy and lightweight compared to other diaphragm materials. This means that the FT3 driver is less prone to breakup and thus nonlinear distortion, while also having an extremely extended frequency response and improved soundstage. Pure sound - 350Ω high impedanceThe FT3 was designed with great sound as the primary goal, and features 350Ω impedance to achieve that. Compared to lower impedance headphones, higher impedance headphones more effectively filter out noise to the listener resulting in a purer sound with higher signal-to-noise ratio performanceThe voice coil is made of ultra-fine Japanese copper-clad aluminum only 0.035mm thick in diameter. This finer voice coil allows the driver to better and more quickly follow signals, has anti-interference capabilities, and allows for thunderous dynamics across a wide frequency response range.Hear the artist’s intent - Asymmetrical internal and external magnetic circuit systemThe FT3 utilizes powerful N52 neodymium magnets to maximize sound quality under its 350Ω impedance design. These magnets have been arranged in an optimized asymmetrical internal and external magnetic circuit system. When the voice coil starts to move during the reproduction of sound, the optimized magnetic circuit balances this movement of the voice coil and diaphragm, especially during large dynamic changes - which allows more effective use of magnetic energy and better control over the voice coil. Quality cable - Furukawa monocrystalline copper wireStandard with the FT3 is a 3m, 23AWG diameter cable consisting of high-purity Furukawa monocrystalline copper wire.Outer shell material: TPEShielding layer: PCOCC-A (26/0.12X2) Insulating layer: PFA Conductor: PCOCC-A (3/20/0.8X2AWG23)Outermost diameter: 2.4mmx2 (parallel structure)Widely compatible - 4 swappable audio plugs come standardThe FT3 cable features swappable plugs of the following 4 kinds:3.5mm/4.4mm swappable plugs3.5mm to 6.35mm adapter4.4mm to XLR-4 balanced adapter*Interchangeable audio plugs are officially licensed from the patent by FABRILOUS.Lighter and stronger - Aluminum alloy constructionThe exterior of the FT3 is made entirely of aluminum alloy that not only feels luxurious to the touch, but is also highly rigid yet lightweight. This gives the FT3 the perfect combination of being comfortable to listen to and being durable enough to withstand life’s challenges.Full of comfort - With a lightweight hollow mesh designThe FT3’s design begins with hexagonal elements as its base, and when combined with how open-backed headphones usually look, gives off a bold sci-fi appearance. The open-back design features a hollowed-out mesh to not only further reduce the weight for greater listening comfort, but also to fully unleash the capabilities of its driver in a more open environment. Removing a layer of veil from your music - Open-backed designThe FT3 features an open-backed design that reduces unwanted vibrations and resonances and results in a larger soundstage, since when the driver is pushing air in the housing the open-back means that air encounters. The result is that details in the music come through more clearly and naturally in a wide open soundstage, just as if you were listening to a live performance.Free to rotate - 3-axis swiveling designThe FT3 has undergone much fit testing in FiiO Labs, and the 3-axis swiveling design is one result of that testing. The 3-axis swiveling design was specifically made so that the FT3 could better fit a wide variety of head and face shapes for improved comfort and better seal to maximize sound quality.Innovative touches - Angled drivers parallel to the earThe FT3’s driver is placed at an angle to be parallel to the ear when worn, which helps to reduce high-frequency response caused by the waves hitting the contour of the ear and not entering it. Angled drivers can also minimize unwanted reflections caused by the shell of the headphone that would cause standing waves and also reduce frequency response distortion. Additionally, towards the rear of the FT3’s shell is a reflective tip that is specifically designed to direct soundwaves produced by the driver to prevent unwanted reflections from interfering with each other, to both further minimize sound flaws and reduce unwanted frequency response artifacts. Rich sounds - 2 sets of distinct-sounding earpadsThe FT3 comes with 2 sets of earpads, each with their own soundSuede earpads: Balanced sound, enhanced ambience, majestic experienceImmitation leather earpads: Clear sound, large soundstage, highly detailedThorough protection - Storage bag includedThe FT3 comes with a storage bag, which comprehensively protects your headphones in a light yet luxurious feeling package.FT3 Basic specificationsHeadphone type: Dynamic driver headphonesFrequency response: 7Hz-40kHzDriver type: 60mm dynamic driverDiaphragm material: Beryllium-plated gasket + DLC diaphragmImpedance: 350ΩSensitivity: 102dB (1Vrms)@1kHzWeight: About 391g (excluding cable)Earpad pressure: 4.0N±0.3NCable length: About 3mCable material: Furukawa monocrystalline copper wireHeadphone connector: Dual 3.5mmAbundant accessories3.5mm interchangeable plug    4.4mm interchangeable plug    3.5mm female to 6.35mm male adapter    4.4mm female to XLR-4 male balanced adapter    Storage case    Imitiation leather earpads    Suede earpads
