"I simply cannot understand why anyone would prefer these to existing wireless headphones."
One example: people with a major investment in the Apple eco-system. Pair it once with your iPhone, and it's also paired with your laptop, with your iPad, with your iPod, etc.
I've had plenty of frustrations trying to get bluetooth headsets to pair with a single device, let alone multiple devices, so anything that makes that easier is valuable to me.
How valuable is another question: another $10, another $50, another $100? That's pricing for the market to decide. I can recognise the technical improvement, which just leaves the question of the monetary value of that improvement.
