KZ Eldar is equipped with a single dynamic driver IEM featuring a custom super-linear driver with HM Graph Signature tuning, 5-precision-technology driver architecture, an OFC dual-parallel anti-tangle HiFi cable, and a gold-plated detachable 2-pin connector. With 24Ω impedance, 105dB sensitivity, and a 20–40,000 Hz frequency range, it delivers audiophile-grade bass, midrange, and treble performance at a fraction of the cost of comparable IEMs. It includes an HD inline microphone with a one-button remote.
