FiiO FH5S Cable

Introduction

When it comes to in-ear monitors (IEMs), audiophiles often focus on the sound signature, driver configuration, and overall build quality. However, the cable that connects the IEMs to your audio source plays a significant role in the listening experience as well. In the case of the FiiO FH5S, the cable is an integral part of the product that reflects FiiO’s commitment to delivering high-quality components across all aspects of their IEMs. The FiiO FH5S comes with a high-quality, modular cable that not only complements the IEMs’ sonic performance but also enhances the overall usability and flexibility of the device.

This review will take an in-depth look at the cable that comes with the FiiO FH5S, discussing its construction, design, materials, and how it affects the overall sound quality of the IEMs. Additionally, we will explore the modular connector system that FiiO has included with the cable, which is a significant feature for users who switch between different audio sources.

Cable Construction and Design

The cable included with the FiiO FH5S is a premium-grade, high-purity silver-plated copper cable. The silver plating on the copper conductors is designed to reduce resistance and improve conductivity, which can result in enhanced clarity, detail, and overall resolution of the audio signal. Silver-plated cables are known for their ability to deliver a slightly brighter and more detailed sound, which pairs well with the hybrid driver setup of the FH5S.

Cable Material: Silver-Plated Copper

The choice of silver-plated copper for the FiiO FH5S cable is an important one. Copper is commonly used in audio cables due to its excellent conductivity, but when plated with silver, the cable can deliver better high-frequency performance. Silver is one of the best conductors of electricity, and by using it to coat the copper, FiiO has created a cable that optimizes both bass performance (from the copper) and treble clarity (from the silver plating).

• Copper Core: Copper provides a warm, full-bodied sound, making it an ideal choice for the core of the cable. It excels in delivering punchy, controlled bass and clear midrange frequencies.
• Silver Plating: The silver-plating enhances the cable’s ability to deliver high-frequency detail and airiness, which can add sparkle and brilliance to the overall sound signature. It helps with the articulation of higher-pitched instruments such as cymbals, strings, and vocals.

This combination of materials makes the FiiO FH5S cable versatile enough to handle the complex frequency range produced by the IEM’s hybrid driver setup. The silver-plated copper design helps ensure that the cable contributes to a balanced and detailed sound without introducing coloration or loss of information.

Cable Geometry and Braiding

The cable features a four-strand, twisted braid design, which is not only aesthetically pleasing but also functional. Braided cables are known to offer better durability and resistance to tangling, as well as reduced microphonics (the rustling noise that can occur when cables rub against clothing). This makes the FiiO FH5S cable not only robust but also practical for everyday use, particularly for listeners who use their IEMs on the go.

• Twisted Pair Design: The twisted strands help to minimize electromagnetic interference (EMI) and radio frequency interference (RFI), both of which can degrade audio quality. By twisting the strands together, the cable can better resist external interference, resulting in cleaner sound.
• Durability: The braided design also adds to the durability of the cable. Braided cables tend to be less prone to breakage, and the flexible nature of the design means that the cable can withstand bending and daily wear and tear without affecting performance.

The cable’s overall thickness strikes a good balance between durability and flexibility. It’s sturdy enough to feel premium and long-lasting, but still flexible enough to avoid becoming cumbersome during use. Additionally, the outer sheathing of the cable is smooth and free from any sticky texture, which is a common issue with lower-quality cables.

Modular Connector System

One of the standout features of the FiiO FH5S cable is the modular connector system, which allows users to easily switch between different termination plugs. The cable comes with three interchangeable connectors: 3.5mm single-ended, 2.5mm balanced, and 4.4mm balanced. This modular design adds a level of versatility that is rarely seen in stock cables included with IEMs.

3.5mm Single-Ended Connector

The standard 3.5mm connector is the most widely used termination for consumer audio devices, including smartphones, laptops, and portable media players. It’s a single-ended (unbalanced) connector, which means that the left and right audio channels share a common ground. While single-ended connections are more prone to crosstalk and interference compared to balanced connections, they are convenient for everyday use and provide a sufficiently clean and clear signal for most casual listening situations.

• Compatibility: The 3.5mm connector ensures that the FH5S can be easily used with almost any audio device, making it an accessible option for listeners who don’t have access to specialized equipment.
• Sound Quality: Despite being unbalanced, the 3.5mm connector still provides excellent sound quality, with a wide dynamic range and clear separation between the left and right channels.

2.5mm Balanced Connector

The 2.5mm balanced connector is commonly used with portable digital audio players (DAPs) and other high-end audio equipment. Balanced connectors provide better channel separation, reduced noise, and less distortion compared to single-ended connections. In a balanced connection, each audio channel has its own dedicated ground, which minimizes interference and crosstalk.

• Improved Clarity: Using the 2.5mm balanced connector with a compatible DAP or amplifier can result in improved clarity, better imaging, and a wider soundstage. The separation between instruments and vocals becomes more defined, making the overall listening experience more immersive.
• Noise Reduction: The balanced design also helps to reduce background noise and hiss, particularly when used with high-sensitivity IEMs like the FH5S.

4.4mm Balanced Connector

The 4.4mm balanced connector, often referred to as the Pentaconn connector, is becoming increasingly popular in the audiophile community due to its robustness and enhanced performance. Like the 2.5mm connector, the 4.4mm balanced connection provides superior sound quality by offering better channel separation, reduced noise, and higher power output.

• Power Delivery: The 4.4mm balanced connector is capable of delivering more power to the IEMs, which can result in a more dynamic and impactful sound. This is particularly beneficial for listeners who enjoy high-volume listening or need extra headroom for more demanding tracks.
• Wider Soundstage: The 4.4mm connector further enhances the soundstage, giving a greater sense of width and depth to the music. It’s an ideal choice for those who prioritize spatial accuracy and want to maximize the performance of their IEMs.

Sound Performance with Different Connectors

The FiiO FH5S cable’s modular connector system allows users to experiment with different terminations and observe the subtle differences in sound performance. Each connector brings its own characteristics to the table, allowing the listener to fine-tune their listening experience based on their equipment and personal preferences.

• 3.5mm Single-Ended: The sound through the 3.5mm connector is warm and balanced, with a focus on musicality rather than technical precision. It’s a great option for casual listening or for use with devices that do not support balanced connections.
• 2.5mm Balanced: When switching to the 2.5mm balanced connector, the FH5S reveals more detail and clarity, particularly in the upper midrange and treble. The soundstage becomes wider, and imaging is more precise, making it a great choice for analytical listening.
• 4.4mm Balanced: The 4.4mm connector delivers the most powerful and dynamic sound, with excellent control over the low end and enhanced separation between instruments. The soundstage is the widest of the three options, and the overall presentation feels more spacious and immersive.
