The asking price is fair for the used market, sitting just above the A$413 median and below the A$432 75th percentile from nine recent Australian comparables. It is not a bargain at A$420, but neither is it ambitious; assuming the listing is complete and functional, the premium over median is modest.
The Mortise is a compelling open-back design for listeners wanting a relaxed, natural presentation rather than an aggressively analytical one. Its 50 mm carbon-fibre dynamic driver, walnut cups, comfortable adaptive fit, and modular 3.5 mm/4.4 mm cable system give it genuine enthusiast appeal, while the relatively easy-to-drive 38-ohm load suits a broad range of amplifiers and DACs. Confirm that the interchangeable plugs, cable, case, and pads are included, since missing accessories would make this merely fair rather than attractive.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
DUNU is a Chinese audio brand founded in 1994, with its origins in Dongguan, Guangdong, where it began as an OEM/ODM manufacturer before moving into its own branded products. The company is now identified with DUNU / DUNU Topsound and has built its reputation over decades of making earphones and in-ear monitors, with a strong emphasis on internal driver development and proprietary acoustic technologies. Public company background details are a little inconsistent across sources, but its Chinese manufacturing base and long heritage in personal audio are well established.
DUNU is best known for in-ear monitors and earbuds rather than full-size hi-fi components. Its range includes dynamic-driver IEMs, hybrid and multi-driver models, and accessories such as modular cables and interchangeable plug systems. Recent and well-known product lines include the SA series, Titan series, Falcon series, and higher-end statement models like the LUNA and Zen Pro, alongside newer releases that continue to target enthusiasts looking for technical performance and refined tuning.
In the market, DUNU sits in the enthusiast-oriented mid-tier to upper-mid-tier space, with some models reaching true flagship pricing. Its reputation is built on solid engineering, polished industrial design, and a generally musical, accessible tuning style, though not every model is aimed at strict reference neutrality. For buyers, DUNU is a credible and established name in modern personal audio, especially if you want well-made IEMs with strong technical ambition rather than a vintage or lifestyle brand.
