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.
