LETSHUOER Sonata Review — Headfonics

Flagship tribrid architecture with 10 drivers

The SONATA uses a flagship tribrid configuration on each side: 2 dynamic drivers, 4 Knowles balanced-armature drivers (BA), and 4 electrostatic drivers (EST). Each driver's acoustic performance is precisely tuned across the various frequency ranges.

Isobaric push-pull design for the dynamic drivers

SONATA uses LETSHUOER’s isobaric push-pull design for its dynamic drivers, enabling deep-reaching and clearly contoured sub-bass reproduction. This woofer configuration multiplies acoustic energy, maximizes extension, and delivers absolute clarity with extremely low distortion even at high volumes. It produces powerful punch and dense spatial depth without any bleed into the midrange, keeping the mids and highs completely uncolored.

Precise resolution with Knowles BA & Sonion EST drivers

SONATA’s midrange and treble section is based on four high-performance Knowles BA drivers, which deliver authentic vocal textures and precise instrumental layering through their fast transient response and high resolution. The super-treble frequencies are handled by a Sonion quad-electrostatic array, providing airy extension and crystal-clear overtones. Working in perfect harmony, these drivers create a seamless transition from solid mids to brilliant highs, making the finest nuances and richly detailed layering of the music audible.

Hybrid cable for flagship performance

SONATA is equipped with a 280-core braided hybrid cable made of monocrystalline copper and silver-plated copper, ensuring uncompromising signal purity and high-fidelity transmission. The native gold-plated 4.4 mm balanced plug ensures a stable connection, while the 0.78 mm 2-pin connector enables easy cable replacement and flexible customization.

Precise 4-way crossover

SONATA uses a meticulously hand-crafted 4-channel sound guide (4-bore), combined with a precise crossover. This architecture eliminates phase interference, ensures seamless frequency transitions, and delivers strict acoustic consistency. As a result, it not only unfolds a holographic 3D soundstage but also preserves a first-class tonal balance.
