Adapter cable Omnitronic 3.5mm to 2×3.5mm, stereo splitter, 1.5 m

Omnitronic adapter cable converts a single 3.5 mm stereo output into two 3.5 mm stereo jacks, allowing one audio source to feed two sets of headphones or two input devices. The 1.5 m length gives sufficient reach for desktop, living-room and portable setups, and the cable is designed for use with smartphones, tablets, laptops and audio systems that use 3.5 mm stereo connections.

Advantages

The cable provides a simple passive solution for splitting stereo signals without requiring power or configuration. Its 1.5 m length balances flexibility and manageability for home and mobile use. The compact 3.5 mm connectors are compatible with most consumer audio devices and allow simultaneous listening or signal routing to two outputs. Construction focuses on basic signal integrity for unbalanced stereo connections.

Suitable for

• Sharing audio from a smartphone or tablet with two sets of headphones
• Connecting a laptop to two speaker inputs or recording devices
• Portable audio setups where a simple stereo split is required
• Home audio systems needing an extra headphone or auxiliary output

Key specifications

• Connector type: 3.5 mm male to 2 × 3.5 mm female (stereo)
• Cable length: 1.5 m
• Signal type: stereo, unbalanced
• Application: audio splitting for headphones and line-level devices
• Compatibility: devices with 3.5 mm stereo jack inputs/outputs

How to use

Plug the single 3.5 mm male connector into the audio output of your source device. Connect headphones, speakers or line-level inputs to the two 3.5 mm female jacks. Adjust volume on the source device as needed; note that both outputs mirror the same stereo signal and volume control is shared. Avoid excessive bending near the connectors to maintain longevity.

Usage recommendations

For best results, use the adapter cable with devices that accept unbalanced stereo signals. If long cable runs or professional balanced connections are required, consider dedicated audio interfaces or active splitters. Keep the connectors and cable clean and avoid tension on the cable during use.
