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 the soundstage 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.
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.
