HarmonicDyne Romantic Open-Back Over-ear Headphones 60mm Bamboo Fiber Bio-Composite Driver with Detachable 4.4mm Balanced Cable

60mm Bamboo Fiber Driver & Open-Back Earcup Design

The Romantic headphone features a self-developed high-stroke bamboo fiber driver—its natural damping keeps the diaphragm moving evenly, minimizing distortion and harsh "ringing". Paired with its open-back earcup structure, it widens thesoundstage for a natural, live-like experience, enhancing instrument/vocal positioning. Its great stiffness-to-weight ratio enables lightning-fast response, and stays punchy without lag in big orchestral swells

High-Efficiency Magnetic Circuit System

The Romantic is equipped with a high-efficiency, high-performance conversion magnetic circuit system—this system cuts energy loss for better electro-acoustic conversion. With 107dB SPL/mW sensitivity, the Romantic headphones perform brilliantly across all sources, from smartphones and laptops to high-end desktop amplifiers, unlocking full performance potential without demanding specialized gear

Romanticism-Inspired Design Philosophy

The Romantic draws on 19th-century Romantic ideals, rejecting cold industrial aesthetics. Its earcups are shaped like natural mountain ridges, turning function into poetic expression. More than a sound device, it amplifies melody emotion—whether stormy passion or moonlit tranquility—celebrating the wildness and solitude of the human spirit

Ergonomic Comfort for Extended Listening

HarmonicDyne Romantic prioritizes wearing comfort with carefully designed earcups and an adjustable headband. The lightweight frame reduces head fatigue during long listening and gaming sessions. Protein leather earpads with "soccer net" fabric lining offer plush cushioning and breathability, conforming to ear contours without pressure. The adjustable headband distributes weight evenly, making it ideal for studio monitoring or cozy home listening

Premium Hybrid Braided Cable

To unlock its ultimate performance, the Romantic comes with an exclusive custom hybrid braided cable. Crafted from silver-plated oxygen-free copper and imported single-crystal copper, paired with tailor-made solder. 4-strand braiding with 924 total cores (231 per strand) ensures unimpeded signal transmission, preserving every emotional nuance in the music. The 4.4mm balanced connector enhances channel separation for immersive soundstage
