## Summary description

PREMIUMCORD KJR-11 is a 3.5 mm jack coupler with gold-plated contacts designed to join two 3.5 mm stereo cables or extend headphone and audio connections.

## Long description

PREMIUMCORD KJR-11 Gold Plated is a compact 3.5 mm jack coupler engineered to join two 3.5 mm stereo plugs or to extend an existing headphone or audio lead. The coupler has gold-plated contacts to improve conductivity and reduce corrosion, and a small, durable housing intended for portable use with smartphones, tablets, laptops, car stereos and home audio components where a short, simple extension or adapter is required.
Advantages
The gold-plated contacts offer improved signal transfer and corrosion resistance compared with unplated connectors, helping preserve audio clarity over repeated connections. Its compact form factor minimizes added bulk and maintains a low-profile connection between cables. The mechanical design provides a stable electrical join that is easy to insert and remove without tools, suitable for temporary joins and quick setup changes.
Suitable for
Extending headphone cables for portable audio devices
Connecting auxiliary inputs in car stereos
Joining patch cables for desktop audio and computer setups
Temporary audio joins during meetings, presentations or rehearsals
Key specifications
Connector type: 3.5 mm stereo (TRS) jack-to-jack coupler
Contact finish: gold-plated contacts for improved conductivity and corrosion resistance
Compatibility: standard 3.5 mm stereo plugs used on headphones, aux cables and portable audio devices
Form factor: compact inline coupler suitable for low-profile connections
How to use
Align each 3.5 mm plug with the corresponding socket on the coupler and insert firmly until a secure fit is achieved. To disconnect, pull each plug straight out to avoid undue stress on the cable ends. Use the coupler only with standard 3.5 mm TRS stereo plugs; it does not convert between stereo and mono wiring schemes or provide impedance matching. Ensure plugs are clean and free of debris to maintain optimal contact quality.
Usage recommendations
For best performance, avoid subjecting the coupler to heavy tension or frequent twisting of joined cables. Store the coupler in a dry environment when not in use and periodically inspect the contacts for dirt or oxidation; a gentle wipe with a dry, lint-free cloth will help maintain reliable connections.
