Slight background: I have a friend with the "original" "Zeo Sleep Mobile", so I'm familiar with the way it looks/acts/connections. I've been thinking about getting one for a bit, and see multiple models at my local store, and various places online. It's pretty unclear, and has the potential to change which model I want to get.
A few related questions:
1) I've searched all around, but can't find detailed information about this. What, specifically are the differences between these three models? The closest I've found is http://www.myzeo.com/sleep/what-difference-between-zeo-sleep-manager-pro-and-pro, but it leaves some questions unanswered. I assume that the Pro has a micro USB port on it, otherwise it couldn't be charged. But does it also contain the docking connector (so you could buy the dock separately)? Does the Pro+ have both (so you could charge with just USB) or just the docking connector? How does it differ (if at all) from the "Mobile" version?
2) On the subject of charging and docks, how many days will the Headband last without being charged (say, when traveling)? I've been searching all over and can't find this info, either. If will last for a few days, it would potentially save lugging the dock around (a potential benefit of the Pro vs Pro+, depending on if the Pro+ has usb, as well). Similarly, is there any way to turn off the headband once it's charged, so that it can be packed, without bluetooth on, draining battery, or needing to be put on the dock?
3) I've found this: http://www.myzeo.com/sleep/update-your-headband. And it's clear that it won't work with the Pro. What about the original Sleep Manager? If it's identical to the Pro+, then I'd think yes, but it's not entirely obvious to me, so I suspect I'm not the only one.
Of course, if I've missed some obvious post, feel free to refer me to it, and similarly move this quesiton somewhere else if it's in the wrong section.
