What is a headphone extension cable

Headphone patch cords originated from mobile phones. Generally speaking, if your mobile phone can play music, but you have high requirements on the sound quality of music, then the randomly configured headphones may not be able to complete the good music playing function. At this time, the headphone extension cable can convert the 2.5MM jack on your mobile phone into a 3.5MM jack. The next available headset can not only experience super high sound quality, but also call. High-fidelity headphones used by many music enthusiasts are also played using the headphone extension cable. The 3.5MM jack is a type of jack that is common to our popular headsets.
