The DUNU Hulk Pro is a hand-braided 4-core IEM upgrade cable with MMCX connectors, built on 22 AWG Furukawa Electric OCC copper with an independent aluminum shield around each core. It suits IEM owners who move between sources, since its Quick-Switch system includes 2.5mm and 4.4mm balanced and 3.5mm single-ended plugs.

Who the DUNU Hulk Pro is for

  • MMCX IEM owners: MMCX connectors let it replace the stock cable on earphones that have MMCX sockets.
  • Balanced players: 2.5mm TRRS and 4.4mm TRRRS balanced plugs are both included, for players and dongles with either balanced jack.
  • Switching sources: DUNU's Quick-Switch modular plugs change between balanced and 3.5mm TRS single-ended without swapping cables.
  • Cable upgraders: The hand-braided 4-core weave uses 22 AWG Furukawa Electric OCC copper with secondary fire refinement, every strand insulated and each core in its own aluminum shield.
  • Skip it if: your earphones use 0.78mm 2-pin sockets; this listing is the MMCX version only.
