Using this earset cable is easy. Just connect it to your audio device via the LEMO 3 - pin connector. When handling it, be gentle to avoid bending the cable too sharply as it may damage the internal wires. Store it in a cool, dry place when not in use. There's no need for special cleaning, but you can use a soft, dry cloth to wipe it if it gets dirty. Since we couldn't test this unit, keep an eye on its performance during initial use.
