H HIFIHEAR ST16 Plus 16-Core Silver-Plated IEM Cable (QDC

The KBEAR ST16 Plus is a 2-meter, 16-core silver-plated single-crystal copper IEM replacement cable with QDC-type pins and optional balanced terminations for clearer highs, solid mids, and extended reach.

This upgraded ST16 Plus cable from H HIFIHEAR is built for listeners who want longer reach and improved signal transmission without changing earphones. It pairs with a wide range of popular detachable IEMs — including many KZ, CCA, TFZ, and other models — and comes in multiple connector types and terminations (2.5mm/3.5mm/4.4mm) to match your source. The design focuses on balanced sonic performance, durability, and comfortable wear for everyday listening or on-the-go use.

How does this cable change sound compared with stock cables?

ST16 Plus uses 16-core 5N high-purity single-crystal copper conductors with silver plating to marry copper’s weighty lows and warm mids with silver’s enhanced high-frequency detail. The multi-strand 23AWG braid improves clarity, staging, and treble resolution without being overly bright.

• 16-core single-crystal copper with silver plating for better treble and detail
• 224 cores per strand for consistent signal delivery
• 23AWG diameter and tight braiding for reduced microphonics and improved channel separation

Which earphones and connectors are compatible with the ST16 Plus?

The ST16 Plus supports multiple pin types—QDC, MMCX, 0.78mm 2-pin, and TFZ—making it a flexible replacement for many detachable IEMs. Choose the right pin type for your IEM and select a 2.5mm, 3.5mm, or 4.4mm plug to match your player, DAC, or headphone amp.

Is the cable durable and comfortable for daily use?
