It works fine, but I had a couple issues:
First, the 3.5mm side is not that smooth, you need to force the plug into it a bit at the end to secure it firmly
But a more serious issue is that the 3.5mm side is mono as well, meaning that if you plug a stereo headphone into it, you will hear only one channel. It kind of makes sense, but I did not expect this frankly.
Fir the above reason, unless you really need mono, I would suggest getting the stereo version instead.
