3.5mm audio cable

Product Description of 3.5mm Audio Cable

As a classic interface solution in the field of audio transmission, the 3.5mm audio cable has become a core audio connection component for scenarios including consumer electronics, audio-visual entertainment, office & education, and in-car audio-visual systems, thanks to its wide device compatibility, stable sound quality transmission, lightweight and portable design, and multi-specification adaptability.

Based on the differences in the number of connector pins, the product is divided into three core specifications: 2-pin mono version (dedicated to mono audio transmission), 3-pin stereo version (delivers left and right channel stereo output), and 4-pin stereo + microphone version (supports both stereo audio transmission and voice call functions).

The entire product series adopts mainstream connection types such as male-to-male and male-to-female. Among them, the 3.5mm male connector is responsible for mobile audio transmission, commonly used in accessories like audio cables and headphones; the 3.5mm female connector serves as a fixed audio interface, integrated into the main bodies of various devices such as mobile phones, speakers, and computers. These two components work together to achieve accurate audio signal transmission and meet diverse usage requirements.

Personal Audio-Visual Entertainment Scenarios

The 3.5mm audio cable caters to different usage needs in personal audio-visual entertainment:

• The 3-pin stereo version is the mainstream choice, widely used to connect mobile phones, tablets, laptops to wired headphones and portable speakers. Through separate left and right channel transmission, it restores immersive stereo sound, ideal for music listening and movie watching.
• The 2-pin mono version is suitable for simple audio devices such as mono radios, vintage voice recorders, and basic speakers, realizing basic audio signal transmission.
• The 4-pin stereo + microphone version is specially designed for scenarios combining audio-visual entertainment and voice interaction. When connecting mobile phones to headsets with microphones, it can not only transmit stereo audio but also support voice calls and in-game voice communication, perfect for mobile gaming and online meetings.

Office, Education & Conference Scenarios

The 3.5mm audio cable acts as a core audio accessory in office, education, and conference scenarios:

• The 3-pin stereo version enables connection between laptops, projectors and conference room speakers, ensuring clear transmission of courseware audio and video conference sounds.
• The 4-pin stereo + microphone version is suitable for pairing desktop computers with headsets with microphones, meeting the needs of audio output and voice input during online teaching and remote work without the need for additional microphones, simplifying the device connection process.
• The 3.5mm male-to-female audio extension cable solves the problems of inconvenient audio interface positions and insufficient cable lengths in conference equipment, flexibly adapting to different conference room layouts.

In-Car Audio-Visual & Outdoor Scenarios

The 3.5mm audio cable demonstrates excellent adaptability in in-car audio-visual and outdoor scenarios:

• The 3-pin stereo version can connect mobile phones to car audio systems, realizing playback of mobile phone music and navigation voice through the car system and enhancing the driving experience.
• Most outdoor portable speakers are equipped with 3.5mm female interfaces; paired with the 3-pin stereo audio cable, they can connect to mobile phones, players and other devices for outdoor music playback.
• The 4-pin stereo + microphone version also has applications in outdoor live streaming scenarios, connecting mobile phones to microphones with mics to ensure stable audio collection and transmission.

In addition, for small audio-visual devices such as MP3 players, portable CD players, and vintage game consoles, the 2-pin mono and 3-pin stereo 3.5mm audio cables are core accessories to ensure the normal operation of basic audio functions.
