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

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.
