Immersive, natural soundstage

Designed for listeners who value the essence of sound, the DUNU Mortise delivers a warm, rich, and full-bodied listening experience. Vocals sound structured and harmonious, the bass is deep and controlled, while the highs fade gently without harshness or sibilance. Its spacious, well-structured sound remains fatigue-free even during long listening sessions and is ideal for pop, vocals, and instrumental music.


Open-back acoustic architecture

The open design minimizes internal reflections and interference from standing waves, allowing the sound to spread naturally. This expands the width and depth of the soundstage and ensures precise imaging as well as an immersive, balanced listening experience that remains comfortable even during extended use. The sound imaging is relaxed yet precise, with clearly defined spatial positioning.


Ultra-thin carbon fiber dynamic driver

Equipped with a 50-mm full-range driver featuring a high-flux-density N52 neodymium magnet circuit, the ultra-thin carbon fiber diaphragm ensures stable, linear performance. The W-shaped diaphragm profile and flexible surround system minimize distortion while improving detail reproduction and resolution across the entire frequency spectrum.

This configuration delivers ample power and precise transient response. It reduces unwanted distortion while improving speed and control.


Adaptive Ergonomic Structure

The Mortise’s headband features an adaptive suspension design that naturally adapts to different head shapes and distributes pressure evenly across the crown. A carefully tuned elastic steel frame provides stable support with minimal clamping force, ensuring a secure yet relaxed fit. Soft, highly elastic memory foam ear pads preserve acoustic integrity while offering long-lasting comfort.


North American black walnut housing

The housing is crafted from carefully selected North American black walnut, prized for its naturally warm grain and understated character. Beyond its aesthetic appeal, the material offers beneficial internal damping properties that help control resonance and reduce unwanted high-frequency artifacts.


Warm and Rich Sound

The Mortise’s tuning leans toward a warm, full-bodied sound. Vocals are richly textured, the low frequencies extend deep with controlled impact, and the highs are gently defined. Thanks to the balance between resolution and long-term comfort, the sound is spacious and relaxed, offering a refined listening experience.


High-purity single-crystal copper cable

The detachable cable consists of high-purity single-crystal copper conductors, ensuring efficient signal transmission with minimal loss and interference. A nylon outer jacket provides additional vibration damping and helps preserve fine details and maintain a clear, natural soundstage.

It features the Q-Lock Mini connector system with both 3.5 mm single-ended and 4.4 mm balanced connectors, as well as a 3.5 mm to 6.35 mm adapter. This ensures compatibility with a wide range of portable and stationary audio devices, as well as future-proof flexibility


Premium carrying case

The package includes a custom-made fabric carrying case that provides premium protection for your headphones and accessories.
