## Long description

PREMIUMCORD KJR-25 is a compact adapter that converts a 6.3mm (1/4") stereo plug to a 3.5mm stereo jack. It allows headphones, portable audio players and other devices with a 3.5mm plug to connect to amplifiers, mixers, instruments and audio equipment with a 6.3mm socket. The adapter is designed for straightforward signal transfer without extra wiring, enabling quick format compatibility in studio, stage and home environments.
Advantages
The adapter provides a reliable mechanical connection between two common stereo connector formats, preserving left and right audio channels. Its compact size makes it easy to carry and store, while the metal-plated contacts ensure consistent conductivity and resistance to wear. The simple plug-and-play design requires no tools or additional components, delivering an immediate solution when connecting consumer devices to professional audio gear.

 Contact plating: metal-plated contacts for reliable conductivity

How to use
Insert the 6.3mm (1/4") male plug of the adapter into the device's 6.3mm socket, then plug the 3.5mm headphone or audio cable into the adapter's 3.5mm female jack. Ensure connectors are fully seated to avoid intermittent contact. No configuration or power is required; the adapter passes the stereo audio signal through directly. To disconnect, gently pull the connectors straight out to avoid strain on the cable or socket.
Usage recommendations
For best results, use the adapter in dry, indoor environments and avoid excessive bending or force on the connectors. Inspect contacts periodically for corrosion or debris and clean gently if needed. The adapter is intended for line-level and headphone signals; avoid using it with devices that require balanced or specialized connectors without verifying compatibility.
