H HIFIHEAR ST16 Plus 16-Core IEM Cable 3.5/4.4mm

The KBEAR ST16 Plus is a 2-meter, 16-core 5N single-crystal copper silver-plated replacement IEM cable designed to lift detail, improve highs, and deliver durable, tangle-resistant daily use for MMCX and various pin connector earphones.

If your stock earphone cable feels short, thin in texture, or lacks clarity, the ST16 Plus offers a longer, higher-purity wired option. Built from 16 strands of 5N OCC single-crystal copper with silver plating, this braided cable prioritizes clearer treble, stronger mid presence, and fuller low-end body while remaining soft, flexible, and resistant to tangling. Multiple connector and plug choices make it broadly compatible with popular IEMs and portable players.

How will the ST16 Plus change sound detail and tonal balance?

The 5N OCC single-crystal copper cores with silver plating aim to combine copper’s warm mid-bass strength with silver’s enhanced high-frequency clarity. The dense 16-core braid and 23AWG construction provide finer signal transmission for improved resolution and micro-detail.

• 16-core, 5N OCC single-crystal copper with silver plating for improved highs and midrange cohesion
• 224 individual wire strands per direction for refined resolution
• 23AWG braided design to balance conductivity and flexibility

Which connector and plug options does the cable support?

The ST16 Plus offers multiple connector ends so you can match your earphones or player: MMCX, 0.78mm 2-pin, TFZ, and QDC. Output terminations include 3.5mm standard and optional balanced 2.5mm or 4.4mm plugs for use with balanced-capable devices.

• Swap between MMCX, 2-pin 0.78mm, TFZ, or QDC connectors
• Select 3.5mm single-ended or 2.5mm/4.4mm balanced plugs when ordering
• Gold-plated connectors and upgraded processes for longer lifespan

Is the cable comfortable, durable, and suitable for active use?

The cable uses a soft, one-piece injection-molded construction and a special braid to stay supple and resist tangles. Earhooks are ergonomically shaped to fit the auricle, so the cable remains comfortable during long listening sessions or light movement.

• Soft, tangle-resistant braid that stores easily
• Durable injection-molded terminations and tension-tested life
• Ergonomic earhooks that sit comfortably for continuous wear

What device and earphone models is this cable compatible with?

Designed as a universal upgrade, the ST16 Plus suits many popular IEMs and portable players when you choose the correct connector and plug. It works well as a replacement cable for MMCX and 2-pin earphones and is useful for hi-res players supporting balanced outputs.

• Compatible with MMCX and 2-pin earbuds such as Fiio FH3, FH7, FH9, FA9, FH5S

• Available with 3.5mm, 2.5mm, or 4.4mm plugs for single-ended and balanced sources

Who is this for? The KBEAR ST16 Plus is aimed at audiophiles and everyday listeners who want a longer, higher-fidelity wired connection without changing earphones. It’s ideal if you need a 2-meter cable for desktop or studio setups, want improved treble detail and midrange presence over stock cables, or require flexible connector and plug choices for cross-brand compatibility.
