20cm 3.5mm Replacement Earphone Cable with Gold-Plated Connectors and TPE Sheathing

This AV134 model replacement earphone cable is designed for audio equipment requiring a 3.5mm connection. It serves as a functional extension or direct replacement for existing cables on headphones, portable speakers, and other compatible devices. The specified 20-centimetre length provides a practical solution for close-proximity connections or for replacing worn or damaged original cables. Its construction uses standard audio-grade materials, including an enameled copper core and gold-plated interface connectors, to facilitate clear signal transmission for everyday listening needs.

Features and Construction

The cable is built from several distinct components, each serving a specific function in audio signal transfer and physical durability. The materials selected are common in entry-level and mid-range audio accessories, balancing performance with cost-effectiveness for a replacement part.

Material and Build

The core conductor is made from enameled copper, a standard material used for its electrical conductivity in audio cables. The 3.5mm interface connectors feature a gold-plating layer applied over the metal contact points; this plating can help maintain a clean connection surface by resisting oxidation. The connector shell, which houses the plug's internal components, is constructed from either ABS plastic or an aluminium alloy, depending on the specific production batch. The outer cable is sheathed in Environmental TPE (Thermoplastic Elastomer), a flexible and durable plastic material designed to protect the internal wires.

Size and Practical Fit

The cable measures 20 centimetres in total length, which is also listed as 0.2 metres. This compact size makes it suitable for short-run connections, such as linking a phone to a small portable speaker on the same desk or replacing a short section of cable on a pair of headphones. The wire has a diameter of 3mm, contributing to a standard profile that is neither overly thick nor exceptionally thin. This combination of length and diameter offers a specific fit for users who need a short, direct connection rather than a long, trailing cable.

Uses and Placement

With its 3.5mm interface, this cable has broad application across consumer audio devices. It is a utilitarian component rather than a specialised audiophile product, intended for common scenarios where a reliable physical connection is the primary requirement.

Event or Professional Use

In casual professional or event settings, such as small presentations or background music playback, this cable can serve as a reliable, short-link connection. It could connect a laptop's headphone output to a portable PA speaker or link a media player to an auxiliary input. Its gold-plated connectors may offer slightly more consistent performance in varied environments compared to plain metal contacts by resisting surface corrosion that can cause intermittent audio signals.

Everyday Home Use

For home users, this cable is a practical spare or replacement part. It can extend the connection on computer speakers, replace a damaged cable on a pair of over-ear headphones, or connect a tablet to a compact stereo system. The available colour options—black, grey, and white—allow for a basic match with common electronic device aesthetics. The 20cm length is particularly relevant for tidy setups where excess cable needs to be minimised.

Benefits and Buying Value

The value of this product lies in its specificity and role as a functional replacement component. It addresses a clear need for a standardised audio connection of a defined short length, using widely compatible materials.

Reuse and Low Maintenance

As a replacement cable, its primary benefit is restoring functionality to audio equipment without replacing the entire device. The materials used, like TPE sheathing and gold-plated contacts, are chosen in part for their longevity in normal use. The cable requires no specialised maintenance; simple care involves avoiding kinks and keeping the connectors clean to ensure a good physical connection, which supports repeated use over time.

Why Choose This Product

This cable is chosen for its exact specifications: a 20cm length, 3.5mm connectors, and a 3mm diameter. It fits scenarios where a generic, longer cable would create clutter or where an original equipment cable has failed. The inclusion of an enameled copper core and gold-plated interfaces indicates attention to basic signal integrity within its product category. For buyers, it offers a straightforward solution matched to a common audio jack standard and a specific short-length requirement.
