1. Overview of the KZ ZS5 Stock Cable
The KZ ZS5 comes with a detachable cable that uses a two-pin 0.75mm connector, making it easy to swap out the stock cable for upgrades or replacements. This flexibility is one of the defining features of the ZS5 and other IEMs from Knowledge Zenith (KZ), allowing users to experiment with different cables for various benefits.
The stock cable is a functional yet standard offering, providing basic connectivity without any frills. It is a typical budget cable found with many entry-level IEMs. While it performs its core function of delivering audio from the source to the earphones, there are several areas where improvements could be made, and audiophiles often explore aftermarket options for a better overall experience.
2. Design and Build Quality
A. Material Composition
The KZ ZS5 stock cable is made from a basic copper wire enclosed in a rubbery plastic sheath. Copper is a commonly used material for IEM cables due to its excellent conductivity. However, the quality of the copper and the insulation materials used in budget cables are often not as refined as those found in higher-end models.
The plastic insulation on the KZ ZS5 cable is soft and flexible, which is a positive for portability and flexibility. However, it can also be prone to tangling, which can be frustrating for daily use. The rubbery texture can make it difficult to neatly coil the cable, leading to tangles, especially when storing the earphones in a pocket or a bag.
B. Design Aesthetics
Visually, the KZ ZS5 cable is quite simple and unassuming. The clear plastic coating reveals the copper wiring beneath, which gives it a transparent, slightly shiny appearance. While this is a standard design for many budget IEMs, some users may find it a bit basic compared to braided or fabric-covered cables that offer a more premium look and feel.
The two-pin connectors are color-coded to ensure proper polarity when attaching the cable to the earpieces. This is a helpful feature, especially for users who may not be familiar with detachable cables. The 3.5mm plug is standard for most portable devices, such as smartphones, digital audio players (DAPs), and laptops, ensuring broad compatibility.
3. Ergonomics and Comfort
Comfort is a critical aspect of any IEM cable, especially for users who wear their earphones for extended periods. The stock KZ ZS5 cable, while functional, has some limitations in this regard.
A. Over-Ear Design
The KZ ZS5 cable is designed for an over-ear fit, meaning the cable loops around the top of the ear, helping to reduce microphonics (cable noise) and providing a secure fit. This over-ear design is common in higher-end IEMs and is appreciated by audiophiles for its ability to stabilize the earphones and minimize distractions caused by cable movement.
The cable’s flexibility helps with the over-ear fit, but its rubbery texture can sometimes cause discomfort, especially for users with sensitive skin. Over time, the cable may feel sticky or tacky, particularly in warmer climates where sweat can accumulate. Users may prefer a more comfortable material, such as silicone or fabric, which is commonly found in aftermarket cables.
B. Microphonics
Microphonics, or the transmission of sound through the cable when it rubs against clothing or other objects, is a common issue with many IEM cables. The KZ ZS5 cable, while designed to reduce microphonics with its over-ear design, still suffers from this problem to some extent. The rubbery texture of the cable can create friction noise when it brushes against clothing, particularly during physical activity such as walking or exercising.
While microphonics can be mitigated by using a cable clip or adjusting the fit, some users may find the noise distracting, especially when listening to quieter music genres like classical or acoustic.
4. Durability and Longevity
The durability of the stock KZ ZS5 cable is adequate for a budget offering, but it may not withstand heavy use or harsh conditions. Users who are rough with their cables, such as frequently coiling and uncoiling them or using the IEMs during rigorous activities, may find that the cable wears out more quickly than desired.
A. Stress Points
One of the most common failure points in any IEM cable is the connection between the cable and the earpieces or the plug. The KZ ZS5 cable has strain relief at both ends, but the strain relief is minimal and may not provide sufficient protection against repeated bending or pulling.
The two-pin connectors are relatively sturdy, but repeated detachment and reattachment can wear down the connectors over time. Additionally, the 3.5mm plug, while functional, does not feature a reinforced or angled design, which can lead to wear and tear if the cable is frequently bent at this point.
B. Long-Term Use
Over time, the cable’s rubbery texture may degrade, becoming more prone to stickiness or even cracking in extreme cases. This is a common issue with plastic-coated cables, particularly in humid or warm environments. Users who live in such climates or who plan to use the IEMs extensively may want to consider upgrading to a more durable cable.
5. Sound Performance
While cables may not dramatically alter the sound signature of earphones, they can have subtle effects on sound quality, particularly in terms of clarity, detail, and noise transmission. The stock KZ ZS5 cable performs adequately in this regard, but some users may notice improvements with an upgraded cable.
A. Signal Transmission
The stock copper cable provides reliable signal transmission for the KZ ZS5 earphones, ensuring that the hybrid driver configuration can perform as intended. However, higher-quality cables, such as those made from silver-plated copper or pure silver, can offer better conductivity and lower resistance, potentially resulting in improved clarity and detail in the sound.
For most users, the differences in sound quality between the stock cable and an upgraded cable may be minimal. However, for audiophiles who are particularly sensitive to small changes in sound, an upgraded cable could provide a more refined listening experience.
B. Noise Isolation
The cable’s role in noise isolation is indirect but important. A good seal from the earphones themselves provides most of the noise isolation, but a well-designed cable can contribute to a quieter listening experience by minimizing microphonics and interference. The KZ ZS5 stock cable does an adequate job here, but aftermarket cables with better insulation materials may offer improved noise isolation.
6. Upgrading the KZ ZS5 Cable
