By now, I take it you saw the leash that they're throwing in to help anchor them for swimming and other such activities? I'm trying to figure out how the leash really attaches into the holes I see on The Dash. My best guess is maybe they're magnetic or that the leash recesses into the holes and grab onto The Dash. I've been speaking with the inventor (Nikolaj) a lot, and I intend on asking him.
For the amount of features on a 100 mAh battery, 3-4 hours is quite a bit of battery time (4 hours for just music listening and 3 for music and use of sensors). For many people, it might be ample power. Nevertheless, I have to agree that it could be rough for us power users who tend to drain batteries -- even with the amazing charging case that's included. A few people had asked whether Bragi could make it possible to charge The Dash via a cable while it's in use, which I thought is an great idea. Nikolaj misunderstood the suggestion (twice), and although he liked the overall idea, he thought the two posters meant to store a charging cable within The Dash's housing to enable this possibility, which clearly wouldn't work due to the housing's size. I tried to re-clarify their idea, so I'm waiting on a response from Nikolaj. It really shouldn't be difficult to implement their idea. I would love the option to be able to plug a Y-cable, whether from the charging case and/or a USB outlet, into The Dash while I'm wearing it. It wouldn't be much different than having a cord on traditional headphones, only when the charge is complete an hour later, you just yank them out! It would be even better if the charging cord could wind into the charging case when not in use, but even if there weren't room within the case for a winding mechanism, I'd be fine with keeping a separate spare cord in my bag. For long distance runners, bikers, etc. who would really rely on the music and sensors, I bet they'd really appreciate this feature -- otherwise, they'll be screwed midway through their race when the power dies. Even in an office, on a long day outside, etc., this option could come in handy. Eventually, I'm sure Bragi will find a way to pack at least twice the battery power into the same amount of space . . . but until technology catches up, hopefully this other idea might come into play.
