First, the Nectar headsets are different because they fit inside your ear, instead of using a loop around your ear. I wear glasses, so I've never been happy with headsets that have an ear loop.
Next, they embrace their position on your head. Instead of trying to be small and unobtrusive, these headsets are a showpiece. The 'daisy' flower model looks like you might be wearing a flower in your hair! The skull and crossbones model could be a tattoo or earring, and it even lights up! There is no attempt to be subtle with that one.
I had the chance to try it out at CES and I found it very comfortable, and it stayed put as it should. I'm looking forward to an extended test, in a variety of conditions.
They have plans for a wide variety of attractive in-ear headsets, and im really looking forward to their unique designs. But they need your help via Christie Street, a boutique e-commerce site specializing in crowd sourced gadgets.
