The price is a bit steep, but it does exactly what I needed. I bought it because I had a problem with the jack port on my laptop. With this, my headphones (both audio and microphone) work properly. Tested on Windows 10 with Samsung handsfree and Marshall Major Headset.

Update: It requires attention not to bend/stretch the cable. After a few months, it started losing connection with the port because I had it in a position where it was constantly "hanging".
