The 3.5mm (1/8") stereo TRS connector is more commonly known as the Headphone Jack on portable mp3 players and mobile phones. This splitter cable features a male 3.5mm stereo (TRS) plug on one end and a pair of 3.5mm stereo (TRS) jacks on the other end, each with molded connector housings and strain relief boots. This splitter cable is ideal for splitting the audio output from a mobile device so that two people using earphones can listen at the same time.Warning: This cable is intended as a splitter only. Attempting to use it to combine two stereo signals into a single stereo signal can cause damage to your equipment. The only proper way to combine two audio signals is by using a mixing board.
