I have not used this product for everything but I have used the headphone jack and HDMI port. The hub works great with my iPad Magic Keyboard. As for the headphone jack, I can start and stop music on my headphones, but I can't adjust the volume. I used the HDMI port to connect to my TV and it worked great and looked good on the TV screen. I have yet to try to transfer the files but I am very happy with the purchase so far.
