The headphones are fairly comfortable, and the mechanism for charging them is great - you just rest them on the cradle in the picture. I have worn them for 2 days pretty much nonstop at work and the cutouts have been fairly minor. I swivel in my chair and they hold up fine.
The only bad part was the "out of the box" experience, where you have to wait 16 hours for the batteries to charge. The base station has yet to report that the batteries are actually fully charged. Also, the headphones felt like they were dead at first, but after playing around with them they seem to have come to life and everything works great.
