I received this because I work from home and use an old laptop my IT department gave me to use which has separate microphone and headphone jacks. I don't use it for anything other than a phone. I don't know about these connectors but the IT guy told me I need a connector like the one in the picture to make it work. Too bad I didn't buy it sooner, hunched over the laptop for almost 1.5 months and yelling into it was stupid.
