Specification

BQEYZ WINTER II — Hybrid Dynamic + PZT Bone-Conduction In-Ear Monitor

Silky sound · Supreme comfort · Re-engineered bone-conduction system with refined aluminum housing

12 mm Dual-Cavity DD PZT Bone Conduction 5-Axis CNC Aluminum Anodized High-Gloss Single-Crystal Copper Litz 0.78 mm 2-Pin 3.5 / 4.4 / Type-C 5–40 kHz

Key Features

Hybrid architecture: Custom 12 mm dual-cavity dynamic driver for bass + PZT piezoelectric bone-conduction driver (≈11.6 mm assembly) for mid/treble ambience and detail.
Re-engineered PZT unit: Japanese silver-palladium ceramic paste (Pd ratio raised from 2%→5%) improves conductivity, clarity and sensitivity.
High-power motor system: Optimized neodymium magnetic circuit + DAIKOKU DCCA coil for wider dynamics, faster transients and better separation.
Dual-cavity airflow design: Reduces turbulence and phase error—lower nonlinear distortion and deeper, cleaner bass.
Refined comfort: New housing is ~22% smaller than the previous generation; ergonomically contoured for long, stress-free wear and more efficient bone-conduction transmission.
5-axis CNC aluminum shell: High rigidity raises natural resonance frequency and lowers spurious amplitude for a purer, quieter background; anodized high-gloss finish.
Upgraded cable: 4-core single-crystal copper in Litz T2 architecture, supple hand-braid for low resistance and transparent sound.
Three terminations included: 3.5 mm SE, 4.4 mm balanced and Type-C options with 0.78 mm 2-pin interface.

Sound Signature

WINTER II is tuned for a smooth, balanced response with glossy highs and an open, organic stage. Upgraded dynamic and bone-conduction drivers contribute airy extension, precise imaging and layered space; vocals remain clear and emotive while bass transitions are tight and seamless across the spectrum.

Engineering Highlights

PZT Bone Conduction
The piezoelectric driver excites the rigid aluminum shell to transmit mechanical energy efficiently. Higher Pd content (5%) in the Japanese silver-palladium paste boosts sensitivity and treble brilliance while controlling artifacts.

Magnetic Circuit + Coil
High-flux neodymium motors with a DAIKOKU copper-clad-aluminum voice coil enhance conversion efficiency and linearity, delivering punchier dynamics and cleaner mid-to-high detail.

12 mm Dual-Cavity Dynamic
Independent cavities create smoother airflow during diaphragm travel—minimizing turbulence and phase inconsistencies for lower distortion and deeper, firmer low-end.

Aluminum Monocoque
5-axis CNC machining, flawless chamfering and an anodized surface improve durability, wear resistance and resonance control.
