New Dual-Chamber Beryllium-Plated Dynamic Driver
Truly Custom, Exceptionally Sound The LETSHUOER Cadenza 4 features a new 10mm large-diameter beryllium-plated diaphragm dynamic driver. The beryllium diaphragm's lightness and rigidity reduce distortion and significantly improve transmission speed, making the earphones easier to drive. It delivers natural sound, spacious and powerful low frequencies, and detailed sound performance, perfect for listening to light, acoustic music.
Combined Sonion x Knowles High-End Balanced Armatures
The Cadenza 4 includes one Sonion BA and two Knowles BAs, each optimized for different frequency ranges. This precise tuning enhances sound density, midrange performance, and detail, with naturally bright high-frequency extension.
Nanometer Acoustic Tubes
To achieve smooth integration of dynamic and balanced armature drivers, the Cadenza 4 uses a three-way acoustic conduit and a four-way electronic crossover, with 50μm physical conduit printing technology ensuring accurate and consistent sound. The four-way electronic crossover precisely controls frequency distribution to minimize phase errors, delivering clear and detailed sound layers and a comfortable listening experience.
Custom 3D-Printed Ergonomic Cavity
In collaboration with HEYGEARS, LETSHUOER crafted the Cadenza 4's cavity, referencing a database of ear sizes for the perfect fit. The design ensures comfort for long-term wear and enhances durability. The faceplate is made of CNC matte aluminum alloy, offering a refined tactile and visual experience.
392-Strand Single Crystal Copper Silver-Plated Cable
The Cadenza 4 comes with a 392-strand high-purity single crystal copper silver-plated cable, enhancing sound purity and fidelity. The detailed, rich sound is transmitted without loss. The cable features three interchangeable 90° plugs, greatly increasing compatibility with various devices.
