H HIFIHEAR ST16 Plus 2M IEM Cable 5N OCC Silver-Plated

The KBEAR ST16 Plus is a 2-meter, 16-core 5N OCC silver-plated replacement IEM cable engineered to improve clarity, extend reach, and offer multiple connector and balanced plug options for most in-ear monitors.

If your stock earphone cable is too short or you want clearer, more detailed sound from wired listening, the ST16 Plus provides a longer, high-purity alternative. It combines single-crystal copper cores with silver plating for a wide frequency balance, soft earhooks for comfortable wear, and optional MMCX, 0.78mm 2-pin, TFZ, or QDC connectors to suit popular IEMs and DAPs. Choose between 2.5mm, 3.5mm, or 4.4mm plugs depending on your source device and listening setup.

How does the ST16 Plus affect sound quality?

The cable uses 16 individually insulated cores built from 5N (99.999%) single-crystal copper with silver plating, which aims to combine the warmth and solidity of copper with silver’s clarity in the upper frequencies. The result is intended to be a more detailed treble response while maintaining a full-bodied lower end.

• 16-core construction for reduced signal loss and improved separation
• 5N single-crystal copper for coherent mids and controlled bass
• Silver plating enhances high-frequency detail and clarity
• 23 AWG braided arrangement improves durability and noise rejection

Which connector and plug choices are available, and why do they matter?

The ST16 Plus offers multiple connector types (MMCX, 0.78mm 2-pin, TFZ, QDC) and several output plugs (2.5mm, 3.5mm, 4.4mm). This flexibility lets you match the cable to many common IEM shells and to balanced or single-ended headphone outputs on players and amplifiers.

• MMCX and 2-pin choices fit a broad range of aftermarket IEMs
• TFZ and QDC options support specific proprietary sockets and versatile compatibility
• Gold-plated connector surfaces resist corrosion and maintain contact quality
• Balanced 2.5mm/4.4mm plugs available for devices supporting balanced outputs

What ergonomic and build features improve daily use?

The cable is designed to be soft and tangle-resistant, with molded ear hooks shaped to follow the ear for secure wearing. The one-piece injection-molded terminations and stress-tested wiring increase longevity for frequent plugging and movement.

• Soft, memory-retaining earhooks that fit most auricle shapes
• One-piece molding at terminations reduces failure points
• Durable braid resists tangles and stores compactly
• Passed high-intensity tension testing for extended life

How long is the cable and what use cases does that support?

At two meters, the ST16 Plus exceeds typical stock cable lengths and gives freedom for desktop setups, portable players in pockets, or couch listening without moving the source. The additional length is especially useful when you prefer wired reliability over Bluetooth or when you need more reach for studio or gaming environments.

• 2.0 m length accommodates desktop DAPs, music players, and casual movement
• Useful for DJs, home audio rigs, and workstations that sit away from the listener
• Reduces strain on connectors compared with short, taut cables
• Offers more flexibility for seated or relaxed listening positions

Who is this for: The KBEAR ST16 Plus is suited to audiophiles and everyday listeners who want a longer, higher-quality wired connection for their IEMs, people replacing worn or broken cables, and owners of compatible IEMs (MMCX, 2-pin, TFZ, QDC) looking to upgrade to silver-plated 5N wiring and optional balanced connectors. If you need greater reach, improved treble detail, and a comfortable, durable cable for portable or home use, the ST16 Plus is a practical option.
