3m Auxiliary Audio Cable.

This is a 3.5mm auxiliary audio cable, commonly known as an AUX cable. It's used to connect audio devices like smartphones, MP3 players, or laptops to speakers, headphones, or car stereos. The packaging mentions "2.4A", which is likely related to charging capabilities if the cable also supports data transfer or charging, although its primary function is audio. The cable is white and appears to be a standard length based on the coiled presentation.
