Can I Use Just the Microphone from Wired Earphones with My Phone?

Yes, you can definitely set it up to use just the microphone from wired earphones! If your setup involves a combo jack, you’ll need a specific type of splitter that separates the headphone and microphone inputs. I personally use a similar setup where I connect my headphones to the computer’s audio jack and use an old headset’s microphone through a splitter into the mic jack. Just make sure it's not a regular splitter—get one that's designed for separating those signals. If you're using a laptop or a mini PC with only a combo jack, you'll need another specialized splitter that changes the male 3.5mm jack into two female jacks for mic and headphones. If you’re up for a DIY project, you could also wire it directly to achieve the same results, although that would involve more hassle!
