The technology behind 'Microphone & Headphone Combo' involves integrating two audio ports, combining both listening and microphone functions into a single 3.5mm jack on your laptop.

1. Legacy 3.5mm Jack.
For older laptop models (or desktop computers), there are two 3.5mm ports divided into two types:
Red Port: designated for Microphone (speaking).
Green Port: port reserved for Headphone (listening).

2. Evolution of the 3.5mm Port
For newer laptop and desktop models, the Microphone & Headphone combo is seamlessly integrated, promoting a more compact device and contributing to size reduction.
Devices like headphones have also transitioned from dual plugs to a single plug to be compatible with modern devices.

With the Microphone & Headphone combo, any 3.5mm headphones can be used to connect to your laptop, even those designed for phones. Especially as video calling apps become increasingly popular, having a headphone and a microphone for conversations is essential for frequent laptop users.
