DESIGN PHILOSOPHY

Inspired by Bu Lianshi, the gentle and elegant lady of the Three Kingdoms era, this product blends Eastern classical charm with modern Hi-Fi craftsmanship. The earphones feature a combination of an aluminum alloy faceplate and a resin cavity, with each material playing to its strengths: the aluminum faceplate delivers a refined yet robust texture with excellent acoustic damping to suppress cavity resonance while creating an exquisite, premium aesthetic; the resin cavity is lightweight and skin-friendly, ensuring zero weight pressure during long listening sessions while further optimizing the internal acoustic chamber. The exterior design is elegant and understated, free from unnecessary ostentation, reflecting the gentle and balanced nature of Bu Lianshi in history. Striking the perfect balance between aesthetics, wearing comfort, and acoustic performance, it is not merely an audio device, but an acoustic collectible enriched with Three Kingdoms heritage—ideal for both daily portable use and desktop listening, bringing ancient grace to your ears.

 

DESIGN PHILOSOPHY

One-pass four-iron mixing unit, full air volume range under precise control

1 Dynamic Driver + 4 Balanced Armatures Hybrid Setup, Effortlessly Handling All Music Genres Utilizing a 1DD + 4BA hybrid acoustic driver architecture, one large dynamic driver is responsible for building a solid bass foundation, while four high-performance balanced armature drivers meticulously split the mid-to-high frequencies, working in seamless harmony. The dynamic driver provides a natural and expansive sonic base, giving music structure and atmosphere; the multiple balanced armatures accurately reproduce rich mid-to-high frequency details, rendering subtle harmonics in vocals and instruments. Paired with a customized crossover network, the frequency transitions between different drivers are precisely tuned to eliminate the phase disjointedness common in multi-driver setups, delivering a coherent and smooth soundstage. The entire acoustic system pursues balance and harmony across all frequencies without artificially emphasizing any single range. Whether handling pop hits, classical traditional music, vocal tracks, or instrumental solos, it faithfully reproduces full, natural sound that preserves the original depth and emotion of the music.

TUNING PHILOSOPHY 

Balanced Harmony in Every Note, Meet Bu Lianshi in Your Ears.

Adopts a professional tuning approach aimed at a balanced three-frequency presentation. The bass features moderate quantity with natural decay and speed, providing just the right amount of dynamic musical support without feeling muddy or bloated; the midrange is smooth and steady, delivering natural vocals with accurate, comfortable imaging; the treble extends smoothly and softly with rich detail retrieval, free from harsh sibilance or sharpness. The overall sound signature is neutral and non-fatiguing, without intentionally boosting or cutting any frequency range. Balanced weighting across the spectrum avoids harsh listening experiences, making long immersive sessions fatigue-free. It seamlessly accommodates vocals, traditional classical, pop, light music, and more—staying faithful to the original recording to deliver music in its truest form.

Dual Connectors Option, Freedom to Upgrade Cables 

Equipped with a standard detachable cable interface, offering both 3.5mm and 4.4mm connector options to fit smartphones, portable digital audio players (DAPs), DAC/amps, and various audio gears. The 3.5mm single-ended option offers high versatility for everyday portable listening; the 4.4mm balanced connector lowers the noise floor and expands dynamic soundstage performance, catering to professional critical listening. Supporting cable upgrades, audiophiles can swap cables with different materials and specifications according to personal preferences to fine-tune tonal characteristics, unlocking versatile listening experiences and enhancing playability. The connectors feature optimal insertion resistance and stable, reliable contacts designed for durability against repeated plug-unplug cycles, fully meeting audiophile DIY upgrade demands.

4-Core Braided Silver-Plated Oxygen-Free Copper Cable 

Comes equipped with a 4-core braided silver-plated oxygen-free copper (OFC) cable encased in a transparent PVC jacket with an outer diameter (OD) of 1.45mm. The OFC silver-plated composite conductors offer excellent electrical conductivity, minimizing audio signal loss during transmission and preventing signal attenuation and unwanted sound coloration. The 4-core braiding effectively reduces microphonic noise (stethoscope effect) caused by cable friction; the flexible, tensile-resistant transparent PVC casing showcases the refined texture of the silver conductors underneath. The cable faithfully transmits the original audio signal from the drivers, maintaining a clean and transparent sound profile.
