RAS. It works.

It also works well on my Samsung Galaxy Note 1 on my Lenovo Yoga Ultrabook 2 Pro. It allows me to use such conventional headsets (like Sennheiser) rather than in-ears not always very comfortable.

On my smartphone, it also serves to make me a little different connections with an external microphone to use a looper software and make beat boxing. By cons, with a multimedia headset for PC, my correspondents complain too big microphone volume. The impédences must be different. It therefore requires that I remove the microphone much of my mouth.

Nothing to do with the cable itself, but in passing information to those who would provide this use.
