for my headset jack (4 points) works with, so do not press it down, you have to play on depth. There, it works but I have a loss on the stereo, it sounds like mono (compared with and without extension, the difference means)
if it sinks evil, was a big waste of his, no more volume.
I bought a 3.5 converter 6 to the brand mark and even worries.
not tried with a stereo headphone jack 3 points.
So for you to see.
