InLine Audio Adapter 3.5mm Plug / 2x 3.5mm Stereo Socket

The InLine Audio Adapter 3.5mm male / 2x 3.5mm Stereo female provides a 3.5 mm male plug and two 3.5 mm stereo female sockets in a compact black housing. It is designed to let you connect two devices with 3.5 mm stereo jacks — for example headphones and PC loudspeakers — to a single reproducer or audio source with a 3.5 mm stereo jack.

Advantages

This adapter allows simultaneous connection of two 3.5 mm stereo devices to one 3.5 mm output, preserving standard stereo signal routing. Its compact, lightweight design and black finish make it easy to carry and blend with common audio setups. No external power is required and the passive construction avoids signal conversion or latency.

Suitable for

• Sharing audio from a phone, tablet or laptop to two headphone sets
• Connecting headphones and PC loudspeakers to one audio output
• Temporarily splitting a single 3.5 mm stereo output for two listeners

How to use

Insert the adapter's 3.5 mm male plug into the audio output of the reproducer or device. Plug the 3.5 mm stereo plugs of the headphones or speakers into the two female sockets. Adjust the volume on the source device to a safe listening level before full use. If both connected devices have volume controls, set both to a moderate level to avoid sudden loud playback.

Recommendations

Use this passive splitter for simple audio sharing and basic stereo devices. Avoid relying on it for professional audio mixing or where independent volume control and impedance matching are required.
