Importer considerations:
DUNU offers a focused audiophile range, mature accessory ecosystem, international direct sales and a visible dealer network. Performance claims still require production-sample measurement, and natural-wood colour, moisture and finish variation require lot-level controls. Interchangeable plugs, cables, eartips and model-specific drivers also enlarge the spare-parts and compatibility burden.
Commercial evaluation path:
Lock the exact regional SKU and approve golden samples for frequency response, channel matching, sensitivity, impedance, distortion, rub/buzz, cable and connector durability, headband force, wood moisture and finish. Obtain model- and factory-specific material, chemical, packaging and labelling evidence; add electrical, EMC, radio and environmental documentation for powered DAC/AMP products where applicable. Contract DOA handling, local return authority, matched drivers, cables, earpads and labour/freight reimbursement instead of treating the consumer one-year warranty as a distributor service-level agreement.

Products and positioning
Applications
Personal high-fidelity listening at home and on the move; open-back desktop listening; portable DAC/headphone amplification; cable and eartip fit or termination upgrades; audiophile retail demonstration and specialty distribution.
Product strengths
Focused audiophile engineering, a catalogue spanning IEMs through full-size headphones, interchangeable cable/plug systems, first-party international commerce and a visible dealer network. Mortise combines a carbon-fibre dynamic driver, N52 magnetic circuit, natural black-walnut housing and 3.5 mm/4.4 mm terminations; all performance and wood-finish claims remain sample- and lot-verification items.
Market and channel fit
Target customers
Audiophile and enthusiast consumers, specialist headphone retailers, hi-fi distributors, reviewers and demo-led dealers able to explain fit, source matching, open-back use, cable compatibility and regional warranty limits.
Export experience
A current English direct-to-consumer store, stated worldwide international shipping outside mainland China, international warranty wording and a multi-country dealer network demonstrate active cross-border sales. They do not by themselves prove distributor volumes, exclusivity or a local repair SLA.
Partner and service support
After-sales support
The Mortise page states a one-year international warranty and 30-day returns, with a 5% restocking charge when unopened and 10% when opened unless waived; support is listed at [email protected]. A distributor agreement should separately define DOA screening, local return authority, matched-driver replacement, cables/connectors/earpads, wood-finish exceptions, labour, freight and response time.
