Audio cable EFB Elektronik K5813SW.3 3m 3.5mm Black

The EFB Elektronik K5813SW.3 3m 3.5mm Black audio cable is a 3-metre analogue audio lead with male 3.5mm connectors on both ends. It is designed to provide reliable line-level connections between portable devices and audio equipment. Gold-plated contacts minimise contact resistance and help maintain signal integrity over the cable run, while the black outer jacket offers a low-profile, neutral appearance suitable for home and office setups.

Advantages

This 3 m audio cable combines a simple, robust construction with gold-plated 3.5 mm plugs to reduce corrosion and contact noise. The length allows flexible placement of source and playback devices without additional extenders, and the symmetrical male-to-male configuration supports straightforward connection between smartphones, tablets, laptops, DACs, stereo systems and powered speakers. The black finish conceals wear and fits common audio environments.

Suitable for

• Connecting smartphones or tablets to active speakers or car auxiliary inputs
• Linking laptop or desktop headphone outputs to amplifiers or recording interfaces
• Temporary or permanent connections for line-level audio between consumer devices
• Use in home audio setups, conference rooms, classrooms or office desks

Key specifications

• Cable length: 3 m
• Connector type: 3.5 mm male to 3.5 mm male
• Contact plating: gold-plated contacts
• Colour: black
• Signal type: analogue stereo line-level

How to use

Insert one 3.5 mm plug into the headphone or line-out socket of the source device and the other plug into the line-in, auxiliary or headphone socket of the receiving device. Ensure connectors are fully seated to avoid intermittent contact. Route the cable to prevent sharp bends or kinks and avoid placing it next to power cables or equipment that may introduce electromagnetic interference. For best results, use at line-level volumes to prevent clipping on connected inputs.

Recommendations

Inspect connectors periodically for dirt or oxidation and clean gently if required. Store the cable loosely coiled to avoid permanent bends. If long runs are needed beyond 3 m, consider using balanced connections or an appropriate active solution to maintain signal quality.
