The EWI YIN-SPP cables are built with a molded 3.5mm Male TRS on one end and stereo molded 1/4" TS breakout on the other. The 3.5mm (1/8") TRS end has been designed to fit into most device output jacks even if a protective case is installed. These are typically used to provide a stereo output from your phone or tablet to the input of a mixer.
The cable is constructed using EWI TWS-2502 cable which is a 25 gauge, zip-cord style cable.
