BQEYZ Vesper Bone Conduction Wired Earphones

BQEYZ Vesper: Dynamic Driver and Direct-Drive PZT Bone Conduction Hybrid In-Ear Monitor

Like the morning glow brushing your ears, hear the true colors of sound.

A 4μm ultra-thin diaphragm with fast transient response, plus close-ear high-frequency compensation from a direct-drive PZT bone conduction driver, so every vocal note carries sweetness and warmth.

4μm ultra-thin diaphragm, dual hot-pressed

Conventional dynamic diaphragms are formed in a single press, which gives rigidity at the expense of flexibility. Vesper uses a dual hot-pressing process with two mold cycles, accepting a higher production defect rate to balance rigidity and flexibility:

• First hot-press shapes the dome for rigidity, giving crisp, non-fatiguing highs.
• Second hot-press reshapes the surround for flexibility, giving powerful, elastic bass with deep extension.

10.8mm dual-cavity dynamic driver

Combined with the 4μm diaphragm, the 10.8mm dual-cavity dynamic driver brings soundstage and dynamics together: crisp, decisive drums, silky strings, and lush, sweet vocals without dryness or chill.

Direct-drive PZT bone conduction

Ordinary bone conduction merely vibrates; Vesper is engineered to transmit. The PZT bone conduction driver sits at the edge of the shell closest to the ear, in a direct-drive position, for maximum contact. High frequencies are compensated directly through bone conduction, bypassing air loss, so fine overtones and subtle details blend seamlessly with the dynamic driver.

• Lows: solid extension, elastic and rich in transients
• Mids: full and transparent, clear vocals, wide soundstage
• Highs: smooth and effortless, bright yet fatigue-free, with low distortion

3D-printed resin shell with relief faceplate

A durable, crystal-clear 3D-printed resin shell with a faceplate that combines aluminum foil and 3D relief craftsmanship for a deep, layered texture.

Note: because the aluminum foil relief process is random, every faceplate pattern is one of a kind. Photos are for reference only.

Gold-plated 0.78mm 2-pin connectors

Standard 0.78mm 2-pin connectors with a micron-level gold plating resist oxidation, keeping contacts clean and free of noise, dropouts and channel imbalance.

Furukawa copper-silver alloy cable

A brown cable made from silver-plated Furukawa copper-silver alloy: 4 main strands, each braided from 21 ultra-fine 0.08mm cores (7 micro-cores twisted, then 3-core twisted). The multi-layer twisting reduces electromagnetic interference and the skin effect. CNC-machined metal plugs, in 3.5mm single-ended or 4.4mm balanced.
