Cadenza 4 是 LETSHUOER 早陣子推出旗艦型號 Cadenza 12 的 “輕型” 版本。雖然單元少了、機身輕巧了，但仍然帶來高分析力及温暖的調音、充滿空氣感及音色細節。團隊歷經十多個版本的調改及研發，最終成就 Cadenza4 無瑕真實的音質，再度呈現一款散發着聲學無限魅力的藝術作品。

產品特色

全新雙腔體鍍鈹動圈

選用全新 10mm 大口徑鍍鈹振膜動圈單元，鍍鈹振膜擁有輕薄與極强剛性的特點，減少性失真的同時，可以大幅提升傳送速度，令耳機更易驅動。呈現更自然的聲音，以及寬鬆澎湃的低頻氛圍 ，突出聲音的细節表現，聽輕鬆小品文青風格的音樂更為悅耳動聽。

結合 Sonion x Knowles 高階動鐵

Cadenza 4 内置 1 顆 Sonion 聲揚動鐵以及 2 顆 Knowles 樓氏動鐵，結合各單元的優勢頻段，調校出最精準細緻的聲音及分頻，提升聲音密度，中頻表現及细節。高頻延伸自然明亮。

納米聲學導管

為實現平滑順暢的圈鐵銜接，Cadenza 4 以三路聲學導管以及四路電子分頻的方案，配以 50μm 的物理導管列印技術，確保聲音的準確順暢與一致性。四路電子分頻可以精確控制頻率分配來減少聲音相位誤差。音樂層次細節清晰分明，帶來舒適耐聽的音質體驗。

定制 3D 打印工學腔體

Cadenza 4 與 HEYGEARS 黑格科技再度合作，打磨製作耳機腔體。參考多個耳朵體積的資料庫製作最合適的腔體，自然貼合耳廓，確保長時間佩戴都有輕巧舒適的感覺、同時擁有更好的耐磨性，增強使用壽命。面板選用 CNC 磨砂鋁合金材質，觸感細膩質感十足。

392 芯單晶銅鍍銀線材

Cadenza 4 標配 392 芯高純度單晶銅鍍銀線材，提升聲音純淨度以及還原度，聲音細節飽滿豐富，無損傳導耳機聲音能量。採用三種 90° 可換插頭設計，自由搭配組合，大幅提升設備適配性。

Overview

Dual chambered beryllium coated DD

Cadenza4 uses a proprietary 10mm dual-chambered beryllium coated dynamic driver, which possesses the characteristics of being light and extremely rigid. It significantly improves response speed and is easier to drive while reducing nonlinear distortion.

Knowles + Sonion BA Drivers

The combination of Knowles and Sonion balanced armature drivers which makes the Cadenza4 to be packed with resolution, rich in mid-frequency details, and ample treble extension. The array of three high-performance balanced armature drivers leverages the strengths of each unit, precisely capturing the nuances of sound.

Physical and electronic filtering

Cadenza4 adopts three acoustic tubes that are combined with an electronic four-way crossover. The 50μm 3D printed acoustic tubes ensures accurate, smooth, and consistent sound. The four-way electronic crossover allows for precise control of frequency distribution and significantly reduces phase errors.

Lightweight earpieces

Cadenza4 once again collaborates with Heygear Technology to refine the earphone chassis. Ensuring comfortable long-term wear and enhanced durability. The panel is crafted from CNC aluminum alloy material with a matte finish which provides a delicate and textured feel.

High quality stock cable

Cadenza4 comes standard with a 392-strands high-purity silver-plated monocrystalline copper cable, enhancing the fidelity of the sound. With three types of 90° interchangeable plugs,which significantly improves device compatibility.
