What is AUX And how this Headphone Work

If you plug speakers or mics or headsets into a primary device , with the possible exception of some types of USB setups, you’re typically connecting in through what you would call an auxiliary port.

Computer port  (COM1) on a traditional PC is typically configured as an audio aux port. which is the first serial port with a preconfigured assignment for serial devices.

An RS 232 standardization applies to various PC audio attachments, many of which are converted to the 3.5mm or 1/8 inch standard audio jack on a lot of peripheral hardware.

Generally, the use of these audio ports requires different types of adapters and fittings for backward compatibility as system components evolve from many different manufacturers.
