Product information

Description

The StarTech 3.5 mm Audio Coupler Female-to-Female (GCAUD3535FF) is a compact inline adapter designed to join two 3.5 mm male audio cables. With two 3.5 mm female connectors in a black housing, this passive adapter lets you extend or connect standard stereo headphone cables, aux leads, speakers and other analog audio devices where a longer continuous cable is needed.

Advantages

This adapter provides a simple and space-efficient solution for linking two stereo audio cables without additional electronics or power. The compact form factor and black finish make it discreet in home, office or mobile setups. Gold-plated contact surfaces increase conductivity and help reduce corrosion for reliable signal transfer over time. The passive design ensures no alteration of the audio signal path other than the physical connection.

Suitable for

Extending headphone cables to reach further from devices
Connecting in-line aux cables between phones, tablets, or car stereos
Joining speaker or portable audio device leads for temporary setups
Adapting cable lengths for recording or monitoring in small studios

Key specifications

Connector type: 3.5 mm female to 3.5 mm female stereo
Function: Passive inline audio coupler for stereo analog signals
Contact finish: Gold-plated connectors for improved conductivity
Color: Black housing
Form factor: Compact inline adapter, lightweight and portable

How to use

Insert each 3.5 mm male plug into the coupler’s female jacks until fully seated. Ensure both connected cables are compatible stereo 3.5 mm plugs for correct left/right channel transmission. Use the adapter to create a longer continuous cable run or to join temporary connections between portable audio sources and playback devices. No power or configuration is required.

Usage recommendations

For best audio performance, use with quality shielded stereo cables and avoid excessive bending or tension at the connection points. Remove the coupler when not in use to prevent strain on cable ends.
