This is a slim metal-bodied IEM with detachable cables offering 3.5mm, 2.5mm TRRS and 4.4mm TRRRS connector options; metal shells and multi-connector compatibility suit headphone amp users and balanced-output setups. Limited buyer feedback on the AliExpress listing prevents strong reliability claims — treat this as a niche Hi‑Fi IEM candidate rather than a proven widely-reviewed model.
Buyers wanting metal‑shell IEMs with removable cables and balanced connector options; avoid if you need verified long‑term user reviews or measurements.
