Kefine Arnar — 14.5mm Planar + Knowles BA Hybrid IEM

"Wide Soundstage. Three Tunings. One Masterpiece."

The Kefine Arnar is Kefine's flagship hybrid in-ear monitor, combining a 14.5mm planar magnetic driver with a Knowles balanced armature unit for a sound that is simultaneously wide, resolving, and musical. Three interchangeable stainless steel tuning nozzles let you shape the signature to your preference, while the five-axis CNC aviation-grade aluminum housing and 392-wire silver-plated OFC cable with modular 3.5mm/4.4mm plugs deliver a premium ownership experience at every level.

14.5mm Planar Magnetic Knowles BA Driver 3 Tuning Nozzles 5-Axis CNC Aluminum 392-Wire Silver-Plated OFC Modular 3.5mm & 4.4mm 0.78mm 2-Pin Detachable 20Hz – 40kHz 13Ω Impedance “Wish Window” Faceplate

Key Features

  • Hybrid Planar + Knowles BA Architecture — Each earphone integrates a 14.5mm planar magnetic driver handling the full frequency spectrum with a Knowles balanced armature unit joining from ~800Hz to reinforce midrange clarity and treble refinement. The result is a coherent, wide-bandwidth sound with the dynamic authority of a planar and the precision of a BA — the best of both worlds.
  • Three Interchangeable Stainless Steel Tuning Nozzles — The Arnar ships with three pairs of precision stainless steel nozzles, each offering a distinct sound profile: the silver nozzle delivers balanced, neutral tuning; the gold nozzle emphasizes clarity and transparency; and the black nozzle provides a warmer, richer, more relaxed signature. Swap in seconds to match your mood or music.
  • Spacious, Transparent Soundstage — The large 14.5mm planar diaphragm delivers exceptional resolution and fast transient response across the full frequency range. Bass is powerful and controlled, vocals are warm and natural, and treble extends smoothly to 40kHz without fatigue or sibilance — thanks to precise tuning and damping components.
  • Five-Axis CNC Aviation-Grade Aluminum Housing — The shell is machined from aviation-grade aluminum alloy using five-axis CNC with extremely tight tolerances. The thin-wall construction improves acoustic precision while keeping the earphone lightweight and comfortable for extended wear. The iconic “Wish Window” faceplate — inspired by traditional Chinese window patterns symbolizing good fortune — gives the Arnar a distinctive, culturally meaningful aesthetic.
  • 392-Wire High-Purity Silver-Plated OFC Cable — The included 4-strand braided cable features a total of 392 individual silver-plated oxygen-free copper wires, preserving the warmth of copper while enhancing high-frequency extension and detail retrieval through the silver plating.
  • Modular Plug System & Detachable Cable — Interchangeable 3.5mm single-ended and 4.4mm balanced plugs are included for seamless compatibility with any source. The 0.78mm 2-pin detachable connector allows easy cable upgrades and extends the lifespan of the earphones.
