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

The Omnitronic 3.5mm to 2×3.5mm ECO series adapter cable (3 m) converts a single 3.5mm stereo output into two 3.5mm stereo outputs, allowing one audio source to feed two headphones or two line inputs simultaneously. Constructed for everyday use, this splitter cable provides a convenient, flexible connection for portable players, laptops, mixers and compact studio setups where a simple and reliable signal split is required.

Advantages

This ECO series adapter cable offers a straightforward and compact solution for sharing audio or routing a single stereo signal to two destinations. The 3 m length gives greater placement flexibility compared with very short splitters, while the cable's flexibility supports easy routing and storage. The product is compatible with standard 3.5mm stereo jacks and is intended for splitting headphone or line-level signals without altering sound balance when used within typical device impedance ranges.

Suitable for

• Sharing headphone output from smartphones, tablets or portable players
• Feeding two sets of monitors or line inputs from one stereo source
• Connecting a laptop audio output to both headphones and an external recorder
• Small rehearsal or podcast setups requiring simple parallel connections

Key specifications

• Connector configuration: 1 × 3.5mm stereo male to 2 × 3.5mm stereo female
• Cable length: 3 m
• Cable type: flexible audio splitter cable suitable for portable and desktop use
• Signal type: stereo analogue audio for headphone and line-level applications
• Compatibility: standard 3.5mm TRS jacks on consumer audio devices

How to use

Insert the single 3.5mm male plug into the audio output of the source device. Connect headphones or line-level inputs to the two 3.5mm female sockets. Adjust volume on the source and on connected devices as needed. When using headphones, keep overall playback level moderate to avoid excessive volume to either listener; when connecting to line inputs, set levels to match the receiving device to prevent clipping. Disconnect by pulling on the connector housings, not the cable, to help preserve the cable and connectors.

Usage recommendations

For best results, use the cable with devices that support standard headphone or line-level outputs and avoid connecting multiple active outputs together. If precise level matching or isolated outputs are required, consider dedicated distribution amplifiers or active splitters instead of a passive cable splitter.
