Nickel plated connectors - For a high quality connection.

Screened cable (shielded) - This prevents interference and reduces noise and crosstalk from other sources that may be situated around the cable. The signal produced is a lot cleaner with fewer defects.

Durable PVC jacket - This thick jacket helps to protect the cable against wear and tear.

Cable strain relief to protect the cable - Enables the cable to be bent in a multitude of directions without breaking.

OFC - oxygen free copper to increase signal quality across the length of the cable.

This lead could be used for connecting a device such as an ipod with an 3.5mm output into an amplifier with 2 phono inputs, whilst allowing additional phono plugs to be stacked on top, therefore allowing an additional input into the amplifier.
