Noble Audio / Lu Ban NBA-LU-BAN

Noble Audio's "Lu Ban" is a hybrid IEM that combines natural materials with advanced technology. It features a cocobolo wood shell and houses a 10mm wooden composite dynamic driver and two newly developed planar magnetic drivers. Achieving both natural tonality and overwhelming speed, it's a new statement model embodying the precise craftsmanship of a master artisan.

■ IEM Inspired by "Lu Ban"
・The Lu Ban is a new, precisely designed hybrid IEM that combines natural materials with advanced magnetic driver technology. Inspired by Lu Ban, a legendary Chinese craftsman, its exterior design embodies meticulous craftsmanship and respect for materials. The shell is manufactured using cocobolo wood, selected for its structural stability and unique grain pattern, combined with a high-precision 3D-printed resin internal frame. This ensures precise driver placement and achieves consistent acoustic geometry across all units. The driver configuration employs a three-driver setup: a dynamic driver with a 10mm wooden composite diaphragm and two newly developed super-magnetic planar drivers. It is designed to deliver power, speed, and refined expressiveness across a wide range of sound sources. The Lu Ban is a new statement model in Noble's universal IEM lineup.

■ 10mm Wooden Composite Dynamic Driver
・Wood has been used in instrument making for centuries due to its natural resonance and tone. The 10mm dynamic driver used in the Lu Ban incorporates a wood composite material into its diaphragm structure, resulting in deeper, richer, and more controlled bass. The sub-bass extends powerfully without lingering resonance, while the mid-bass maintains a clear and balanced expression. The midrange benefits from rich harmonics and realism. Vocals gain depth and presence, and acoustic instruments retain natural decay and weight. Rather than adding artificial warmth, the wood composite driver brings out musical appeal through a materials engineering-based approach. This dynamic driver forms the "emotional core" of the Lu Ban's sound, delivering natural tone and a tangible sense of presence.

■ Dual Super Magnetic Planar Driver
• Supporting the wood composite dynamic driver are two newly developed Super Magnetic Planar drivers, representing a significant evolution from conventional planar magnetic drivers. The Super Magnetic structure employs a new generation of ultra-high magnetic neodymium-iron-boron material, with precisely controlled copper components added to optimize magnetic flux stability and efficiency. This advanced magnetic circuit design achieves faster transient response, improved reproduction of fine details, and enhanced high-frequency accuracy. The planar driver delivers clarity, airiness, and separation. High frequencies extend smoothly without harshness, maintaining layered structure even in complex music, and preserving clarity without distortion even in information-rich recordings. While the wooden composite dynamic driver provides weight and musicality, the dual Super Magnetic planar drivers deliver speed and technical precision. The combination of the two creates a unified hybrid sound that harmonizes natural tone with analytical precision.

■High-Purity OCC Silver-Plated 4-Core Braided Premium Cable and Accessories
・The Lu Ban comes with a high-purity OCC silver-plated 4-core braided cable designed to preserve signal purity and tonal accuracy. The cable features a fiber braided surface coating, a standard 0.78mm 2-pin connector with L/R markings, and a copper gold-plated 4.4mm balanced plug. Three types of ear tips and a carrying case are included.
