KEFINE Klean SV wired IEMs pair a 10mm DLC diaphragm dynamic driver with a detachable 0.78mm 2‑pin cable and metal housings. They promise punchy low end and cable upgradeability for hi‑fi listeners; suitability depends on fit and cable choice rather than exotic tuning.
For listeners wanting a metal‑shelled IEM with a 10mm DLC driver and replaceable cables; avoid if you need verified comfort or measured tuning data before buying.
