Dunu Mortise
The Dunu Mortise pairs a 50 mm dynamic driver with a carbon-fiber composite diaphragm in handsome black-walnut cups, creating an undeniably distinctive full-size design. Head-Fi highlights its premium material approach, while the supplied Q-Lock cable adds welcome flexibility through both 3.5 mm and 4.4 mm terminations. A carbon-fiber diaphragm, walnut earcups, and balanced connectivity give it enthusiast appeal.

Assessments of Build Quality, Usability, and Overall Propositions.
Comfort Fit
75/100
The available review does not discuss fit, clamp, pad comfort, heat, or long-session wearability. Although the listed weight is approximately 325 g, there is no reviewer evidence on how that weight is distributed in use.
Build Quality
77/100
The review describes attractive black-walnut earcups and identifies the Mortise as a dynamic headphone built around a 50 mm driver. It does not comment on the durability of the headband, yokes, connectors, pads, or long-term finish quality.
Features Usability
80/100
The supplied specifications list a detachable 3.5 mm headphone-side cable and Q-Lock interchangeable 3.5 mm and 4.4 mm source plugs, which should offer useful source compatibility. The available review does not comment on the cable's handling, connector security, accessories, or day-to-day ergonomics.
Value for Money
85/100
At roughly $400–$430, the Mortise sits in a competitive enthusiast-headphone segment. None of the available review material weighs in on whether its performance, construction, or supplied cable system is especially compelling relative to similarly priced alternatives.
