HPOI x Celest Yaksha BC Hybrid In-Ear Monitors
The HPOI x Celest Yaksha BC is a five-driver hybrid in-ear monitor that combines two dynamic drivers, one balanced armature, one planar magnetic driver, and a self-developed bone conduction unit. Created through a collaboration between Celest’s acoustic engineering and HPOI’s ACG aesthetic, it delivers detailed, immersive sound with a distinctive anime-inspired design featuring custom faceplates of the HPOI kanban musume character.
Five-Driver Hybrid Configuration with Bone Conduction
The Yaksha BC employs a carefully tuned five-driver architecture with four-way crossover. An 8 mm custom dynamic driver handles low frequencies with strong magnetic force and controlled extension. A 10 mm LCP dynamic driver covers the mid-low to midrange for natural timbre and resolution. Lou’s RAN-62462 composite balanced armature unit reproduces mid to high frequencies with full, realistic vocals. A miniature planar magnetic driver extends the highs and ultra-highs with excellent air and detail. The self-developed 7 mm contact bone conduction unit adds subtle vibration that enhances low-frequency texture, ambiance, and on-stage presence without overpowering the overall balance.
Custom Anime Faceplates and Visual Design
Each earpiece features a unique printed anime faceplate of the HPOI kanban musume character, finished with smooth resin that preserves fine textures. Cherry blossom and mother-of-pearl elements are layered over the artwork, with every pearl detail hand-polished for a refined luster. The translucent black housings and coordinated braided cable complete a cohesive visual identity that appeals to both audiophiles and ACG enthusiasts.
Precision Acoustic Tuning
Celest’s acoustic team worked with HPOI auditory supervision to refine the frequency response. The bone conduction unit assists low-frequency extension and provides stronger spatial cues, resulting in a coherent, engaging presentation that remains balanced across genres. The low 10 Ω impedance and 105 dB sensitivity make the monitors easy to drive from a wide range of sources while retaining dynamic control and detail.
High-Quality Detachable Cable
The included cable uses 6N OCC conductors in a four-strand hand-braided Litz construction. It terminates in a 3.5 mm single-ended plug and 0.78 mm 2-pin connectors, offering reliable contact and a soft, flexible feel. The multi-color braiding complements the faceplate artwork while maintaining signal integrity over its 1.2 m length.
Complete Accessory Package
Every set includes three pairs of silicone ear tips in S/M/L sizes, the braided cable, a protective hard case, a themed badge, a cleaning cloth, and a user manual. The compact case keeps the monitors and cable secure for daily carry or travel.
