Letshuoer's Cadenza 4 are hybrid in-ear earphones featuring a dynamic driver with a beryllium-plated membrane and three balanced armature drivers. The design of these earphones has been entirely conceived around this specific feature, resulting in high-quality reproduction that combines rich sound with astounding precision.
Cadenza 4 earphones feature a brand-new dynamic driver with a 10 mm diameter beryllium-plated diaphragm. This diaphragm is characterized by its thinness and high rigidity. This considerably improves response speed, making the earphone easier to drive while reducing non-linear distortion. The result is a more natural sound and a fuller reproduction of low frequencies.
Cadenza 4 earphones are also equipped with 2 Sonion drivers and a Knowles balanced armature driver coupled with a surgically precise crossover filter. These additions enhance tonal density, enrich midrange detail and extend the treble frequency range. The combination of these 3 balanced armature drivers delivers a sound reproduction as delicate as it is transparent.
Cadenza 4 earphones adopt a solution involving 3 acoustic tubes coupled to a 4-channel electronic crossover. With its cutting-edge 50μm 3D-printed acoustic tubes, Letshuoer has ensured that they are calibrated to recreate a faithful, smooth and balanced sound. The four-channel electronic crossover allows precise control of frequency distribution and considerably reduces phase errors.
The Cadenza 4 earphones are the opportunity for a new collaboration between Letshuoer and HeyGear Technology to refine the chassis. The body of the earphones is precisely calibrated to ensure long-term wearing comfort. The front plate is made of CNC-machined aluminum alloy with a matt finish, giving a textured handfeel.
The earphones come with a cable made of 392 strands of pure silver-plated single-crystal copper, offering optimum conductivity combined with minimal signal loss. Furthermore, the cable comes with 3 interchangeable jack connectors (2.5mm / 3.5mm / 4.4mm) for maximum device compatibility.
