H HIFIHEAR ST16 Plus 16‑Core IEM Cable QDC/2m

The KBEAR ST16 Plus is a 2‑meter, 16‑core silver‑plated single‑crystal copper replacement IEM cable with multiple connector options (including QDC) for clearer highs, fuller mids and tighter lows.

This replacement cable from H HIFIHEAR is built for listeners who want a longer, more durable wired connection and a measurable audio uplift over stock cables. It pairs with a wide range of detachable in‑ear monitors (KZ, CCA, TFZ and similar models) and offers 2.5mm/3.5mm/4.4mm balanced or single‑ended termination choices. The ST16 Plus focuses on raw conductor quality, robust connectors and wearable comfort so you can use wired IEMs for commuting, studio reference, or stage monitoring.

How does the ST16 Plus improve sound compared with a stock cable?

The ST16 Plus uses 16 cores of 5N high‑purity single‑crystal copper with silver plating, combining copperʼs warm mids and strong bass with silverʼs enhanced treble clarity. The braided 23AWG construction reduces interference and refines detail retrieval for vocals and cymbals.

• 16‑core, 5N single‑crystal copper with silver plating for balanced tonality
• 23AWG diameter and tight braiding for lower resistance and better transient response
• Improved high‑frequency detail without overly brightening the overall sound

Which connectors and terminations are available and why choose QDC?

The ST16 Plus is offered with MMCX, 0.78mm 2‑pin, TFZ and QDC plug choices and gold‑plated contacts for corrosion resistance. QDC-style pins feature a fuller coverage structure that increases mechanical stability and broad compatibility with contemporary detachable IEMs.

• Interchangeable pin types for KZ, CCA, TFZ and many aftermarket IEMs
• Gold‑plated connectors to extend contact life and reduce oxidation
• Available terminations: 2.5mm, 3.5mm and 4.4mm to match balanced or single‑ended sources

Is the 2‑meter length practical for daily use or performance settings?

The extended 2‑meter cable gives you freedom for desk use, stage setups and situations where the source isnʼt in your pocket. Its soft, anti‑tangle braid and reinforced strain reliefs make it comfortable to wear and durable under repeated coiling or movement.

• 2 meters of cable for flexible routing and left/right source placement
• Soft ear hooks shaped for comfort during long sessions or active use
• Injection‑molded strain reliefs and tension testing for longevity

How do I choose the right color and connector for my IEMs?

Pick the connector that matches your earphones (MMCX, 2‑pin, TFZ or QDC) and a termination that fits your player (3.5mm for phones, 2.5mm/4.4mm for balanced DACs). Color choices — deep black‑blue, neutral brown‑blue and bright silver‑blue — let you match aesthetics or visibility on stage.

• Verify your IEM pin type before ordering to ensure proper fit
• Choose 4.4mm or 2.5mm for balanced rigs, 3.5mm for standard devices
• Pick a color that complements or contrasts your earphones and setup

Who is this for: The KBEAR ST16 Plus suits audiophiles, touring musicians, sound engineers and everyday listeners who prefer a wired connection and want improved fidelity, durability and length. If you use detachable IEMs and need a longer, better‑sounding cable with flexible connector and termination options, this cable is a practical upgrade.
