Presenting

NEUME

The all new, compact sized high-end universal fitting in-ear monitor for audiophiles and musicians. Featuring a five-driver, tri-hybrid configuration, NEUME delivers a warm, engaging, and spacious sound signature that creates an immersive experience that is both captivating and musically expressive.

Articulate, airy treble

A carefully sculpted treble response introduces crisp articulation, fine detail, and a sense of openness. The controlled presence region enhances definition and instrumental texture, while the upper-frequency response contributes sparkle and perceived air. This balance creates an engaging, revealing presentation without an intentionally aggressive tonal character.

Natural, expressive midrange

The midrange is carefully balanced to maintain a smooth, spacious, and fatigue-free presentation. A gently relaxed lower-to-center midrange provides a sense of depth and openness, while a gradual rise into the upper midrange restores presence, definition, and vocal articulation. Instruments retain their natural character, allowing vocals, and intricate arrangements to emerge with clarity without becoming overly forward.

Deep, controlled bass

A commanding low-frequency foundation delivers impressive sub-bass extension, visceral impact, and satisfying rumble. The elevated bass response adds richness and weight without excessive mid-bass bloom, preserving separation and clarity throughout the frequency spectrum.

Precision crafted

Neume is meticulously crafted using advanced 7-axis CNC machining, allowing for intricate geometries, dimensional accuracy, and refined surface detailing. Precision engraving introduces distinctive patterns that seamlessly compliment the sculpted anodized aluminum housing, creating a sophisticated balance between technical engineering and artistic expression. Beyond its stricking appearance, the machined construction provides a rigid, durable foundation for the internal acoustic components.

Optimized performance

At the heart of Neume is a custom-engineered, 3D printed acoustic chamber, developed to accommodate its sophisticated multi-driver configuration. By carefully managing driver position, chamber dimensions, and internal sound transmission, this architecture helps optimize acoustic integration, minimize unwanted resonances, and maintain consistent performance across the frequency spectrum.

Dual-driver synergy

Neume incorporates a push-pull isobaric dynamic driver configuration, utilizing two acoustically coupled drivers working together to reproduce deep, authoritative bass with exceptional control. This configuration is engineered to deliver powerful low-frequency extension while maintaining precision. The result is a rich, impactful bass foundation with satisfying sub-bass depth, controlled mid-bass presence, and minimal intrusion into the midrange.

Seamless integration

A sophisticated 5-way crossover netwrok serves as the foundation of Neume's multi-driver acoustic architecture, carefully distributing the audio signal across designated frequency regions. Each crossover section is developed to optimize the interaction between different driver technologies, balancing their individual characteristics to achieve a cohesive and naturally integrated presentation. This calibrated approach promotes smooth frequency transitions, refined tonal balanced, and exceptional clarity, allowing every driver to contribute harmoniously to the overall listening experience.

Pure signal transmission

Every detail matters, including the connections hidden within. Neume features our proprietary Copper XS internal wiring, developed in-house to provide reliable, high-quality electrical connections between its internal components. Copper XS supports efficient signal transmission throughout the intricate multi-driver architecture. From the external cable connection to the internal driver network, every element is thoughtfully considered in pursuit of a refined listening experience.
