Audio combo jack vs headphone/earphone with mic and speaker connector
Question

63i6EDB91E36AC72128

I see the audio combo jack in my T510 (indicated number 6 in the image), but I've used a regular headphone in it without plugging in the mic connector.

1. How do I hook up a regular microphone - does the port "know" the difference between 2- or 3-conductor microphone plug and a stereo headphone plug?

2. How do I use a headset with separate mic and speaker connections? Is there an adapter I need?
Answer

You may have two options:

Get a new headset with combo jack or
Purchase an adapter that can connect your current headphone with mic and speaker back to the machine audio combo jack.

Here is an example of the adapter / splitter listed on Amazon. There are a number of companies that make competitive versions of this priced between $10 and $15 .

2 порта USB 3.0, 1 порт USB 2.0, выход HDMI, VGA, кардридер "2 в 1" (SD, MMC), универсальный разъем для подключения наушников и микрофона

Чем не устраивает встроенный микрофон?
