H HIFIHEAR KBEAR ST16 Plus 16-Core 5N Silver-Plated IEM

H HIFIHEAR KBEAR ST16 Plus is a 2-meter, 16-core 5N single-crystal copper silver-plated replacement IEM cable that delivers clearer highs, fuller mids and stronger lows for MMCX/2.5/3.5/4.4-equipped earphones.

Designed for audiophiles and on-the-go listeners who want wired fidelity without compromise, the ST16 Plus upgrades stock earphone wiring with high-purity materials, precision braiding and multiple connector options. Its longer 2.0 m length, soft over-ear hooks and durable molding make it practical for desktop, stage, and casual use while preserving sonic detail and reducing microphonic noise.

How does the ST16 Plus change sound compared with standard cables?

The ST16 Plus uses 16 cores of 5N (99.999%) single-crystal copper that are silver-plated to marry copper’s warmth with silver’s air and detail. This material blend improves transient response and high-frequency clarity without stripping midrange presence.

• 16-core braid for improved channel separation and imaging.
• 5N OCC single-crystal copper for cleaner signal transmission.
• Silver plating to sharpen highs and add sheen to detail retrieval.
• 23AWG strands and tight braiding to reduce interference and preserve dynamics.

Will this cable fit my earphones and player?

Yes — the ST16 Plus is offered with multiple connector choices (MMCX, 0.78mm 2-pin, TFZ, QDC) and a selection of output plugs (2.5mm balanced, 3.5mm single-ended, 4.4mm balanced). Pick the matching pin type and jack to ensure compatibility with most popular IEMs and portable DAC/amps.

• Pin options: MMCX, 2-pin 0.78mm, TFZ, QDC full-coverage.
• Jack options: 2.5mm balanced, 3.5mm standard, 4.4mm balanced.
• Gold-plated contacts for corrosion resistance and reliable connection.
• Broad compatibility with Fiio, KZ, CCA, Shure-style and other MMCX/2-pin IEMs.

How comfortable and durable is the cable for daily use?

The ST16 Plus combines a soft, low-memory outer jacket and ergonomic ear hooks molded to ear contours, so it sits comfortably during long listening sessions or light activity. The cable is produced with a one-piece injection-molding process and passes high-tension testing for long-term dependability.

• 2.0-meter length for flexible setups and less pull on connectors.
• Soft, shaped ear hooks that reduce fatigue and slippage.
• Tangle-resistant braid and neat aesthetic for easy storage.
• Reinforced strain reliefs and gold-plated plugs for longevity.

What aesthetic and color choices are available?

The cable comes in three distinct colorways so you can match your earphones or create a custom look. Each finish keeps the refined braided texture while varying tone to suit personal style or stage setups.

• Deep black-blue: subtle, stage-friendly look.
• Neutral brown-blue: understated and versatile.
• Bright silver-blue: eye-catching and modern.
