I checked this with audacity by recording my voice. When I play the recording, my voice is very low and there was noise ("brrrrr") coming constantly. The volume can be increased if I take the microphone close to my mouth. But this is impractical while working.
I checked the earphone on a HP laptop running Windows 10 (by recording voice in "Voice Recorder" application). I was surprised by the quality of the recording. There were no noise at all and I didn't have to take the microphone close to the mouth. I should mention that my previous earphones worked well with the laptop running Linux Mint. And I didn't even had to bring microphone close to my mouth.
I thought there might be a problem with my laptop's hardware. So I tried using my friend's earphone (AKG) on my laptop. It was working nice and clean. There wasn't that noise and the volume was good.
