Audio adapter cable Omnitronic 3.5mm to 2×3.5mm, 3 m length

The Omnitronic 3.5mm to 2×3.5mm audio adapter cable (3 m length) converts a single 3.5 mm audio output into two separate 3.5 mm outputs. It is intended for splitting headphone or line-level signals so one audio source can feed two devices simultaneously. The cable's 3 meter length offers extended reach for flexible placement of audio equipment in home, portable and professional environments.

Advantages

This adapter cable provides a straightforward, passive solution for duplicating an analog stereo signal without requiring power. The 3 m length delivers room for comfortable routing and placement of connected devices. Metal-plated connectors ensure reliable contact and consistent audio transmission while the flexible cable jacket reduces strain at connection points and supports repeated handling.

How to use

Insert the single 3.5 mm male plug into the audio source's headphone or line output. Connect one or two 3.5 mm headphones, speakers or line inputs to the female jacks. Ensure connectors are fully seated to avoid intermittent signal loss. The passive splitter duplicates the stereo signal across both outputs; avoid using with devices that require separate impedance sensing or active isolation.

Recommendations

For best results, use with consumer-level headphones and line inputs. Keep cable runs away from high-power cables or sources of electromagnetic interference. If you notice level drop or impedance-related issues when driving two low-impedance headphones simultaneously, consider using a headphone amplifier or an active distribution solution.
