    Our refurbished products are in excellent or nearly-new condition, typically returned within our 30-day return period.

    SIVGA Luan’s nickel-coated diaphragm edge balances light weight, rigidity and elasticity to deliver deep, clear bass and smooth, layered mids. Its carbon-fiber dome controls vibration for delicate, non-sharp treble. A 24.5 mm NdFeB magnet with 350 KJ/m³ energy provides a powerful driving force, ensuring high sensitivity and precise sound reproduction.

    Open-back, over-ear design features a CNC-carved solid wood housing refined by traditional grinding, polishing, painting and air-drying. This careful finishing enhances acoustic resonance and adds a premium aesthetic. CNC-machined metal brackets and connectors add strength and a premium finish, while handmade wood cups impart elegant warmth.

    Lightweight, ergonomic build with large oval velvet earpads and a velvet-padded headband provide pressure-free comfort. Leather accents enhance softness. The detachable cable uses a 3.5 mm connector on the housing side for wide compatibility and TPU rubber construction for silent, tangle-free handling.

    Diaphragm Technology
    The Luan’s nickel-coated diaphragm edge combines light weight, rigidity and elasticity to move swiftly and precisely. A macromolecule carbon-fiber dome suppresses resonances, keeping treble delicate and non-fatiguing. Together, they deliver deep, impactful bass and smooth, layered mids that uncover every nuance in your music.

    Magnetic Circuit System
    At its core is a 24.5 mm NdFeB magnet with 350 KJ/m³ energy, generating a stable field that drives the diaphragm with exceptional force. This high magnetic energy boosts sensitivity, faithfully reproducing subtle signal variations. You get a wide dynamic range and
    precise accuracy, from thunderous crescendos to the quietest whispers.

    Wood Housing Craftsmanship
    Each ear cup is CNC-machined from solid wood, then refined by grinding, polishing, painting and air-drying. The result is a silky-smooth, warm surface that enhances acoustic resonance. This artisanal process also reduces internal reflections, delivering a more open, natural soundstage.

    Precision Metal Components
    The headband brackets and connectors are CNC-machined metal, offering rock-solid durability and a sleek, high-end finish. Precise tolerances ensure a perfect fit and lasting integrity. These metal parts extend the headphone’s lifespan and add a subtle sheen that complements the wooden cups.

    Ergonomic Comfort Design
    Lightweight by design, the Luan features large, oval earpads and a velvet-padded headband to eliminate pressure points. The skin-friendly velvet is exceptionally soft, even during marathon sessions. A leather-topped band adds comfort, creating a snug yet breathable fit.

    Versatile Detachable Cable
    Sporting a 3.5 mm connector on the housing side, the Luan’s cable works with virtually any aftermarket option for effortless upgrades. Its high-quality TPU sheath stays flexible and noise-free, so handling won’t introduce rustle. The tangle-resistant design keeps your setup neat and ready to use.
