Earphone cable replacement for 3.5mm interface devices, 20cm length, 3mm wire diameter, TPE outer sheath, featuring gold-plated connectors and enameled copper core in black, grey or white colour options
20cm AV134 Earphone Cable with Gold-Plated 3.5mm Connectors and TPE Sheath

This specific 20cm length earphone cable is designed as a direct replacement or connection solution for audio equipment utilising the ubiquitous 3.5mm interface. The AV134 model combines practical, stated specifications—including a 3mm wire diameter and an environmental TPE outer sheath—with functional material choices like gold-plated connectors and an enameled copper core. It is offered in a choice of black, grey, or white, allowing for basic colour coordination with your devices. The cable's defined length makes it suitable for desktop setups, portable audio gear, or other scenarios where a short, tidy connection is required, avoiding the clutter of excess cable.
Features and Construction

The construction of this audio cable is detailed through its component materials and measured specifications, focusing on functional performance and physical durability for everyday use.
Material and Build
The cable's performance hinges on its stated materials. The core is enameled copper, a standard choice for conducting audio signals with clarity. At each end, the 3.5mm connectors are gold-plated, a feature that helps maintain a stable electrical connection by resisting corrosion and oxidation over time. These connectors are housed in shells made from either ABS plastic or aluminium alloy, both offering protection for the internal connections from physical impacts and strain.
Size and Practical Fit
The cable's physical dimensions are precisely given. It has a total length of 20cm (0.2m), a specific size ideal for short-range connections without leaving excess wire to manage. The cable itself has a diameter of 3mm, contributing to its flexibility and handling feel. It is important to note that these are manual measurements, so minor variations may occur. This defined size makes it a purposeful choice for connecting devices in close proximity, such as a smartphone to a portable speaker on the same desk.
Uses and Placement

With its standard 3.5mm interface, this cable serves a fundamental role in audio connectivity, suitable for both casual and more organised audio setups.
Event or Professional Use
In scenarios requiring neat, short-run cable management, such as at a presentation desk connecting a laptop to a compact speaker or in a studio patch bay for a temporary monitoring connection, the 20cm length and robust connector shells provide a reliable, low-profile link. The colour options (black, grey, white) allow for some discretion in matching equipment.
Everyday Home Use
For daily life, this cable can replace a damaged cable on a pair of headphones, connect a music player to a home stereo auxiliary port, or link a gaming controller to a headset. The TPE outer sheath is designed for flexibility and daily handling, resisting kinks and tangles more than a bare wire might.
Benefits and Buying Value

The value of this product lies in its specification-matched replacement capability and its straightforward, material-driven design that avoids unnecessary complexity.
Reuse and Low Maintenance
As a replacement part, it extends the life of audio equipment whose original cable has failed. The material choices, like the oxidation-resistant gold plating and the durable connector shells, are intended to reduce connection problems and physical damage, minimising future maintenance needs.
Why Choose This Product
You would select this specific cable if you need a 20cm length for a tidy setup, require the audio fidelity associated with an enameled copper core and gold-plated connectors, or prefer the flexibility and colours offered by the TPE sheath. It provides a factual, specification-based solution for connecting 3.5mm devices without any unsupported claims about enhanced audio quality or extreme durability.
