How to use

Insert one 3.5 mm jack into the audio output of the source device and the other jack into the input of the receiving device until each connector is fully seated. Select the appropriate input on the receiving device (for example, AUX or Line-In) and set playback volume on the source to a moderate level before adjusting system volume to the desired listening level. For recording, set source and recorder levels to avoid clipping. When disconnecting, grip the connector housing rather than pulling the cable to prolong cable life.

Usage recommendations

For reliable performance, avoid sharp bends near the connectors and keep the cable away from strong electromagnetic sources or high-voltage power lines to minimize interference. Store the cable coiled without tight kinks. If using in a vehicle, route the cable to prevent pinching and check connections for secure seating before driving.
