What Is an Audio Plug?
Audio plugs are connectors for linking audio devices to speakers or headphones.
These plugs, including the 3.5 mm mini-jack for portable devices and the 6.35 mm connector for larger audio equipment or instruments, facilitate signal transmission. The 3.5 mm plug is commonly used with earphones, while the 6.35 mm plug connects to professional audio gear.
Audio plugs can transmit either stereo or monaural signals, with stereo plugs carrying left and right channels separately for a more immersive sound experience.
