3.5mm Stereo Extension Cable Omnitronic 30210060, 3 m length

Omnitronic 30210060 is a 3.5 mm stereo extension cable with a 3 m length designed to extend audio connections between devices equipped with standard 3.5 mm jacks. The cable provides a straightforward wired extension for headphones, speakers, car audio systems and portable players, allowing more flexible placement of devices while reducing mechanical stress on the original connectors.

Advantages

The cable offers a reliable mechanical extension without requiring adapters or reconfiguration of audio settings. Its 3 m length gives additional reach for connecting devices across a room or vehicle interior. The stereo 3.5 mm connections maintain left and right channel separation and allow continued use of in-line controls and microphones where supported by the connected devices. The simple, single-cable design minimizes signal loss over short distances and supports unbalanced analog stereo audio signals.

Suitable for

• Extending headphone connections to audio sources at a distance
• Connecting portable music players to home or car stereo systems
• Linking smartphones or tablets to external speakers or amplifiers
• Temporary or semi-permanent installations where extra cable length is needed

Key specifications

• Connector type: 3.5 mm stereo male to 3.5 mm stereo female
• Cable length: 3 meters
• Signal type: analog stereo (unbalanced)
• Compatibility: devices with standard 3.5 mm audio jacks (headphones, speakers, car audio, portable players, smartphones, tablets)
• Cable construction: single shielded audio cable suitable for short-distance analog connections

How to use

Insert the male 3.5 mm plug into the audio output of the source device (for example a smartphone, laptop or audio player) and connect the female 3.5 mm jack to the headphone plug or audio input of the target device (for example headphones, speakers or a car stereo). Ensure both devices are powered on and set to the appropriate volume levels before playing audio. If the connected headset includes a microphone or remote, test in-line functions to confirm they work correctly through the extension.

Usage recommendations

For best audio performance, avoid routing the cable parallel to power cords or other sources of electromagnetic interference. Keep cable runs short when possible and avoid sharp bends or heavy tension at the connector ends to prolong service life. If using in a vehicle, secure the cable to prevent movement and reduce wear on connectors.
