The shoes are comfortable, but if you have extra sensitive skin on the bottom of your feet, there is a wavy ridge pattern that takes some getting used to. Registers on PC as an Xinput device instead of a Dinput device. That took me longer than it probably should have because I messed up the first time and didnt realize until I was almost done so had to start from scratch. The connection is excellent! I use the keyboard mostly on a MacBook and a little with Windows. Just like the numerous other people out there, I had one side of my Bose QC25 headphones go out. Its only been 2 months and one charger is starting to come apart and the other has stopped charging. Pieces were easy to tell how they fit together and instructions were pretty easy to follow. I find myself adjusting the ties a few times when I wear them to get the right fit. Unfortunately the mic does not work when Bluetooth is turned off and the headset is wired.
