I have a new touch bar 13" MacBook Pro coming, and I'm looking for a dock for it. I like to use it as a desktop once in a while so some USB ports, SD, external display (either HDMI or Display Port - explained below), and also a headphone port for external speakers. It appears most of the docks do not have a headphone port on them. Besides the OWC USB C dock https://eshop.macsales.com/shop/usb-c/owc/usb-c-dock, are there any others that have a headphone port? Next question is about the display. I have a Samsung 28" 4K monitor that has HDMI and Display Port. With my current 2012 MBP I use HDMI, but with the new MBP, should I use Display Port instead? I don't really know the big difference between the specs of the two. The external monitor connection will help determine which dock I need to buy. Do any of these function as a portable charger at the same time? I think that would also be a really nice feature.
