  • 10 mm DLC+PU driver extends treble by 3 dB for sparkling highs

Tunable IEMs with interchangeable nozzles

The Kefine Delci AE in-ear monitors use a dual-sound tuning system with swappable threaded nozzles. Silver nozzles deliver a warm, smooth signature suited to pop music. Gold nozzles provide high-resolution, bright transparency for classical and instrumental tracks. This design lets listeners match the sound profile to the genre without buying multiple pairs.

Lightweight aluminium shells for comfort

Each housing is CNC-machined from a single block of aviation-grade aluminium for over 35 minutes to ensure acoustic consistency. At only 5.3 g per side, these are among the lightest metal IEMs available, providing a weightless feel during extended listening sessions. The 10 mm DLC+PU dynamic driver extends high frequencies by 3 dB for sparkling treble while maintaining punchy, atmospheric bass.

Hybrid 164-core cable with 3.5 mm plug

The Advanced Edition includes a detachable hybrid cable combining 72 cores of OFC copper for warmth and 92 cores of silver-plated wire for clarity. This 164-core structure delivers a cleaner, more balanced signal than standard cables. The 3.5 mm termination offers broad compatibility with portable players, laptops and desktop audio interfaces.

Questions about this item

How do I swap the threaded nozzles and which step do people miss?

Unscrew the installed nozzle counter-clockwise, align the replacement Silver or Gold nozzle threads, and tighten clockwise until seated; the step users miss is verifying the O-ring sits flat so the seal holds.

What part of the Kefine Delci AE will need replacement first?

The 164-core hybrid cable — 72 OFC copper plus 92 silver-plated cores — sees the most flex and connector cycles, so it typically wears before the CNC aluminum housings or 10 mm DLC+PU driver.

What limits the Kefine Delci AE during hours-long listening sessions?

The 3.5 mm plug and 164-core cable junction heat slightly under continuous drive current, making connector temperature the first sustained-use constraint.
