Recently, I am sometimes asked how to connect headphones with a microphone to a laptop that does not have a separate jack (input) for connecting a microphone …
As a rule, in this case, the user is faced with a headset jack (combo). Thanks to this connector, manufacturers save space on laptop sockets (and the number of wires). It differs from the standard one in that the plug for connecting to it must be with four contacts (and not with three, as with a normal microphone connection to a PC).
Let's consider this issue in more detail …
Laptop only has one headphone and microphone jack
Take a closer look at the laptop socket (usually on the left and right, sideways) – sometimes there are laptops where the microphone output is on the right side, for the headphones – on the left …
By the way, if you pay attention to the icon next to the connector, you can uniquely identify it. On the new combo jacks, the icon is 'headphone with microphone (and usually just black, not marked with any colors)'.
Regular headphone and microphone jacks (pink – microphone, green – headphones).

The very same plug for connection looks like this (see the picture below). It has four contacts (and not three, as on ordinary headphones, to which everyone is already accustomed …).

It is important to note that some old headset headphones (for example, from Nokia, released before 2012) had a slightly different standard and therefore may not work in new laptops (released after 2012)!
How to connect regular headphones with a microphone to the combo jack
1) Option 1 – adapter
The best and cheapest option is to buy an adapter for connecting ordinary computer headphones with a microphone to the headset jack. It costs between 150-300 rubles (on the day of this writing).
Its advantages are obvious: it takes up little space, does not create confusion with wires, and is a very cheap option.

Important: when buying such an adapter, pay attention to one point – it needs one connector for connecting a microphone, the other for headphones (pink + green). The point is that there are very similar splitters designed to connect two pairs of headphones to a PC.
2) Option 2 – external sound card
This option is suitable for those who, in addition, have problems with the sound card (or are not satisfied with the quality of the reproduced sound). A modern external sound card provides a very, very decent sounding in an extremely small size.
It is a device, the dimensions of which, at times, are not larger than a flash drive! But you can connect headphones and a microphone to it.
Advantages: sound quality, quick connection / disconnection, will help in case of problems with the laptop sound card.
Cons: the cost is 3-7 times higher than when buying a conventional adapter; there will be an extra 'flash drive' in the USB port.

3) Option 3 – connect directly
In most cases, if you connect a plug from ordinary headphones to the combo jack, they will work (it is important to note that the headphones will be, but the microphone will not!). True, I do not recommend doing this, it is better to buy an adapter.
Which headphones are suitable for the headset jack
When buying, you only need to pay attention to one point – the plug for connecting them to a laptop (computer). As mentioned in the article above, there are several types of plugs: with three and four contacts.
For a combined connector – you need to take headphones with a plug, where there are four pins (see screenshot below).

There are also separate adapters for such a task (the cost is in the region of the same 150-300 rubles). By the way, pay attention that on the plugs of such a connector there is a designation which plug is for the headphones, which is for the microphone. I somehow came across such Chinese adapters where there was no such designation and I had to literally re-connect the headphones to the PC by the 'method' of tests …
