3.5mm Jack Cable PREMIUMCORD KJACKMF3 — 3 m, male-to-female audio extension

PREMIUMCORD KJACKMF3 is a 3 m 3.5 mm male-to-female audio extension cable designed to extend an existing analogue stereo connection without additional adapters. The cable adds three metres of length between a source and headphones, speakers or portable audio devices while maintaining a simple, plug-and-play wired connection suitable for home audio, car interiors and office workstations.

Advantages

The cable delivers a direct analogue stereo path with a standard 3.5 mm TRS male plug and a matching female jack, enabling compatibility with most consumer audio equipment that uses a single stereo mini-jack. Its 3 m length provides flexible placement options for seating, listening positions and desk arrangements. The straightforward construction reduces the need to remove existing cables or connectors, and the female connector allows the original headphone or device lead to remain attached and protected.

Suitable for

• Extending headphone cables for comfortable listening at a distance
• Connecting portable players or smartphones to car or home stereo inputs
• Providing extra reach for speakers or desktop audio setups
• Temporary audio setups in meetings, classrooms or shared workspaces

Key specifications

• Cable length: 3 m
• Connector type: 3.5 mm male to 3.5 mm female (stereo TRS)
• Signal: Analogue stereo (left/right channels)
• Typical use: Line-level and headphone-level audio extension
• Compatibility: Standard mini-jack equipped headphones, speakers and portable devices

How to use

Insert the 3.5 mm male plug of the extension into the audio output or input on the source device, then connect the headphone or speaker cable into the female jack on the extension. Ensure connectors are fully seated to avoid intermittent contact. Route the cable to avoid sharp bends or heavy strain at either connector, and keep the cable away from power cords or strong electromagnetic sources to minimise noise pickup.

Usage recommendations

For best performance, use the extension for short to moderate cable runs such as room-to-room or desk adjustments; if a much longer distance is required, consider using dedicated audio cables or balanced connections appropriate for longer runs. Disconnect by pulling the connector body rather than the cable to prolong connector life.
