I recently purchased a pair of Sound Intone I68 headphones that come with a built in mic, the issue I'm having with them is that if I Skype someone or use them to talk to someone then I can hear them clearly but they have difficulty hearing me, they say I sound like I'm far away from the mic even though it is built in and hangs less than a few centimeters from my face. Whenever I go to audio settings to try to fix the problem no mic other than the one built into my laptop shows up. Is there a way to boost the strength of the mic or is this a hardware problem and should I just send them back?
